Heartbreaker pt 2, 504bhp, 400trq @ 1.5bar!

Hi,

I would like to take this opportunity to share my experiences, with regards to the latest tuning developments, on the Torque Italia 2.4L Fiat Coupe. Many on here are familiar with the ongoing quest to push the boundaries far beyond anything we’ve done before. All thanks to those for their support and encouragement through the highs and lows on this ground breaking project.

My current spec is:

Forged 2.4L 20v
Big valve head, plus C&B cams
700cc injectors, Bosch Motorsport 044 inline pump, 1.5ltr Surge tank
Tigart exhaust manifold with Tial MVR 44mm ext WG.
Garrett GTX3076 .82ar,3 inch Vband turbine housing.
Full 3.5inch exhaust system.
Methanol injection 50/50
Helix Twin Plate paddle clutch, rated at 550lbs.

A brief insight of the challenges faced. Up to the current levels of tuning, we have been encountering several restrictions which have hampered our ability to break 500hp easily. Earlier this year we were running a GT30r .86ar turbine housing (internally WG), exiting through a 3 inch exhaust system. Surprisingly it turned out to be mostly from the exhaust side i.e. exhaust pipe diameters and wastegate setup. Anyway, not going to bore you with all the techy stuff, but the most popular belief was that the stock manifold would have been the limiting factor and the most extreme claim was the cylinder head flaws. Finally, we have refuted those misconceptions...

Now to the power run at Surrey Rolling Road aka ‘the heartbreaker dyno’. Arrived at 3pm and had a quick nose around my engine bay to check for those notorious boost leaks which have haunted me for the past year. Gave a quick briefing to Charlie (dyno operator) on the current spec level and strapped her down. First run, she almost leapt off the rollers.... blimey!, nearly stalled the ol’ ticker! We struggled for 30mins adding more shackles to keep her down as the torque was overwhelming.
In the end, we were forced to turn the boost down from 1.7bar to 1.5bar, yet at 1.2bar it made 489hp!
There were several runs at the 500hp mark before we settled for the most stable result. As we expected she was running lean after 6k, so 875cc injectors are on the cards. Charlie was amazed that it cracked 500hp on a modest boost level.
Note, the current map is yet to be tweaked by Señor Flea to accommodate the latest upgrades.

So we arrive at 504bhp, 400trq @ 1.5bar with more on the way!

It was well worth all the effort to expand the tuning options for the Fiat Coupe 20vt 5cyl platform.

What a Masterpiece of an engine!

Thanks
Barbz (coming out of the shadows)

Sounds like great results, with more on the way! How does this RR compare with the one Flea uses, anyone know?
Well done Barbz

Eh?

Seriously th', gud jarb buddy - obviously more to come too!

Pffft, "another" 500 horse car? So run of the mill these days Barbz

To think 300 was pushing the envelope not that long ago.

I look forward to a spin in this one

What will be achievable in another few years?!

its less "generous"

well done Barbz, thats an amazing result with that boost on those rollers.....looking forward to the extra "tweaking"

From what I gather the RR Flea uses was recalibrated early in Jan this year and results have dropped as a result, so I suspect this "difference" to be nil. My own 20vt was used to test this theory, and made 335 horses at 1.3 bar. About 2 months later I had it on the RR at red dot (unplanned freebie), and it made 360 at 1.35 bar, and 351 at 1.3

So many variables affect dyno results, I'll leave Flea to comment with any further insight though.

Not at 1.5bar it isn't buddy

At 500hp+ level, 30bhp difference between dyno's is hardly a cause for worry.

I don't disagree for a second!

Re my car, it feels the same to drive after Fleas latest map, despite the difference in the dyno's the car has been on. To me, that's more important than the top BHP number each dyno records, and of course how it drives throughout the rev range.

Now I know my car is running around 350 as the spec and map are good for. A dyno is infinitely more useful for your monster, as your build is pushing the boundaries and a one-off, as you will have no idea what it's pushing out!

As I say, I look forward to a spin

The power at 1.2 bar is crazy, on a higher setting on the road that's going to be an absolute animal!

Well done mate, looking forward to the last bit of fettling!

I wish that was the case as i'm enjoying the exclusivity but there's several in the pipeline, roll on 2012.

Your are welcome for a ride .

Will be in the Bristol area early this week.

When I said one-off, I definitely meant currently

Give me a shout when you're about and I'll happily hop in.

Dont forget its not bhp, its the torque that talks.

The 2.4 delivers more and lower in the rev range. The result is more tractability and more 'under the curve'. Most pub talk boys wont appreciate that in their pursuit of max bhp.

The engine is better than just the max bhp figure, and 500 bhp from a 2.4 will be different to 500 bhp from a 2.0

Id be interested to see when and how the power is delivered.

How are the diffs going to stand this power? Any plans for uprated ancilliary parts so all the gear can cope?

All I want to say is Well Done, you really are the man for this forging/power custom build thing!

I have an strengthened early 5 speed under going testing and so far its holding out.

I can tell you it's an incredible car to drive. With my current setup, lag will definitely be a problem, but in this car there is no lag whatsoever!

The setup allows for loads of torque low down, and before you know it, you're on full boost, at the red line and have to change up. It almost feels like a naturally aspirated car, just 10 times quicker.

As for tractability, you really do struggle to keep the car on the road in 2nd and 3rd gear as the wheels just spin up! You get to crazy speeds in no time and you have to be awake behind the wheel!

It's the perfect road car setup with minimal lag and awesome top end power.

Nice results Barbz

wow.. that is some achievement.

The last time I had a go in it, around 450hp, it was like being in the ring with Mike Tyson. Cant think what it must be like now.

Hats off to the legend barbz, always bringing something special to the forum.

Incredible results,certainly impressive.
Any video footage of it at all?

Well done again Barbzbara.


Proof yet again that your da man.

Don't forget me in the new year Barbz ( re : our conversation )

I'm still in the queue I hope but for a few tweaks to the 2.4 I have.

As you noted in the past, the next bit is the box' & trying to keep it reliable

FWIW pal, I'd probably suggest you look into the cooler I fitted ( the box just gets so hot, very quickly ). I can hear my g/box pump whirring away after 10mins of gentle driving ( when I ever drive it ! )

I remember when Flea told me I only made 440hp, then when I heard it was at only 1.2bar I was quite taken aback, on the road, she runs 1.5, and the difference as you noted is VERY noticeable, quite savage

Keep the updates coming, as 2012 is my turn

Great results Barbz

Yeah, you should come out more!! Exciting stuff going on there though!

nice result Barbz

Hey buddy,

Of course, you'll be one of the first in.
Got some special tweeks waiting for you mate.

Hi, nice results.

Just a few questions about the setup, Where is your redline set ? Which camshaft profile is being used (med road, road max etc.) and At what point do you think (if at all) the turbo will max out on this particular setup ?

Thanks.

great result!!!

Hi

Thanks,

Limiter is set to 7800 but we dumped the run just before 7500 due to lack of fuel (power was still climbing).

Camshaft are just the off the shelf C&B's for the 2.0L, which are one type. I haven't used their timing set up though.

As for the turbo, its maximum flow rate is 64lbs compared to 55lbs of the GT30r, probably gain about 10% more power which translates to about 50hp. We shall see on Tuesday.
I will be running closer to 1.8bar and if power still climbing after 7800, then we'll push it to 8k onwards.

Hi John,

Thanks

Longtine bruv!

Give us a buzz when you got a mo'.

Lots to catch up on.

Fantastic results Barbz, well done mate.

Wow, great to see such progress on high powered Coupes. Barbz you didn't hang around since you've been back!

Yeah, been back a year and a half now, sometimes i wonder myself what going on upstairs.

Good to see you posting so much lately sir - "coming out of the shadows" was very apt.

Now get back to working more tuning alchemy.

EDIT: Oh and congrats on the results.

Congrats on the results

I can´t imagine what feels a Coupé with 500bhp it must be like sitting on rocket or going on the roller coaster

Cheers
Filipe

Congrats Barbz!!

Looking back 3 years ago, JohnS's ar was made 616bhp on race fuel... (if I remember correctly)

I wonder if the 600bhp figure can be achieved with out race fuel??
I know nothing is impossible now a days.

Maybe a question for flea but is there any limits to the standard ECU?? Or will 600bhp be ok to run on the standard management?

Also seeing a you have a tigart manifold, GTX turbo ect I can't wait to see what flea can do with this when it goes back for a "tweak"

When is that planned mate?

Well done barbz good to see your pushing it forward all the time.

Thanks Marco.

John S' ran a gt3082 which is rated at 550hp and he made around that figure on pump gas.

GTX3076 is rated for just over 600hp, so not impossible.

Will be going with a slightly larger on MAF to increase the range and 875cc injectors.

Booked in for Tuesday morning.

It's a big figure 500bhp, a half century of horsepower giving a power to weight ratio of 390bhp/tonne. So what company do we keep with the big 5-0...

I was recently in a Z06 at Donington following Barbz on track with his old setup running 460-470bhp on the same dyno. Now Barbz, aka "Street Warrior", struggles a little in his old age to navigate the corners without lighting up the tyres, but at no point was he holding us up and there was absolutely nothing to be gained in the straights with the Z06. Of course, the Z06 wasn't scrabbling in the corners, in fact there was some significant G to be felt, but it has RWD and fantastic leaf spring suspension (yes the yanks have made it work!). My point being, don't get hung up on this and that technicalities of X vs Y, there is no black and white when making real world comparisons.

We have reached a genuine watershed with the Coupe over the last 2-3 years. Such is the the development, 400 is now the new 300, and 500 is the new 400. The good thing is that it can be backed up with reliability, these engines are being tested with countless track days and hard driving, all without failure. I include many non-forged 350-400bhp engines that have the original engine, these having been pounding the tarmac for the last 2-3 years at full power.

Marco mentions the Bosch Motronic factory ECU, yes that's right, the most powerful and (proven) fastest Coupes do indeed still use the original ECU and with good reason. 100% reliability, an ECU that is far more sophisticated in managing the engine under all situations. I am proud to say that FC Performance has opened up the potential of this ECU far beyond any other tuner across the globe.

The Coupe has never had it so good. Power, suspension, brakes and reliability are all being optimised with ever increasing results. Of course, not to be outdone by the TorqueItalia 2.4, well the FC Performance 2.0 is currently under the knife for some upgrades... as Barbz says we are going to see some interesting developments in 2012

That's a fantastic wright up there flea!!

Interesting to see a little old coupe could and SHOULD be messing around with some big brand ad BIG named cars!!

Fingers crosse Barbz gets into a tangle with some of them one day

FC performance car is under the knife ay...

Could we be seeing the FCperformance coupe VS the torque italia monster 2.4L coupe on a drag strip in 2012???

And it's about time you started playing with your car again Flea!!
What are now.... 3rd on your own league table??

well done barbz nice results keep up your top quality work!!!! catch up with you soon

good write up flea well explianed even i managed to understand it

Thanks Leighton. It gives me the confidance to progress. Nice results all round.

We'll see it as early as next April Marco, assuming Barbz and JBT do some Scuderia sessions.....Spa is an epic track and last year JBT, Taffy and Joe gave the exotica something to think about and i don't believe any of the coupes was 100%!!

Would be amazing if Flea was there too - watch out supercars, the boys are coming for you

Oi! Cheeky.



And i was only in 1st gear!
Running road tyres on the front gave me a hard time all day but had to take the 'bull by the horns' and show who's boss., innit!



Agreed, top job Leighton.

Well done B another mechanical masterpiece.

It's great to see the coupe going from strength to strength.

Barbz i wonder what we could do to mine to help me keep up with those pesky westfields in the SMRC in the dry. We've been discussing over boost buttons and perhaps as GT29 to keep things spooling quickly without mega boost. I know Leighton might not be up with the Motec but i'm sure there are improvements lurking.

By the way how do you find the Tigart manifold, i'm looking at getting one made but if theirs is good then it might save me a few pennies.

Unless you plan to make yours out of gold, I'm not sure you'll be saving anything as those Tigart manifolds are quite expensive!

Depends what you class as expensive Biggenz. Over the last few years whilst building my Coupe race car i have spent a fortune on bits and pieces. My gearbox was the best part of £6k so £1500 for a manifold is relatively reasonable in my book. You only get what you pay for.

I couldn't agree more!

FML.

He Barbz,brilliant result (what else could we expect from you )

over 500bhp at `only` 1.5 bar she`s not even warmed up yet buddy

I really need to pull all my fingers out and get my `old banger` down to you.........if you still have time to fit it in ......after these latest results ,even more people will be beating the path to your door..
great to hear about the latest news well done ....wil you EVER stop

Hi Sparco

Thanks.

Send me current spec' in detail and i'll see where we can improve it. torque.italia@hotmail.co.uk

Regarding Tigarts manifold, it was a bit of an unknown, with no R&D data. I paid £1200 for it and spent £350 having it ceramic coated in and out to increase gas speed and longevity. First test run of the unit proved to be impressive as i hadn't lost any spool but gained it, especially with running a larger Turbo. Throttle response is sharper and feels so much smoother right through the rev band. The dyno graph also confirmed that there weren't any potential restriction at the top end either. Its also very well made and solid in construction (heavier than the OEM). So the thumbs up so far.

To attempt one yourself will prove to be more costly.

Leighton could you put the graph up to prove, just in case we have any 'snake oil' comments.

How drivable is 500+ bhp and what sort of fuel return is there? Genuine interest, not trying to prove any points I might add.

I appreciate that 500+ in a car is hardly going to make it one's family wagon now

LOL!
Blimey, where have you been hiding mate?
Mothball that thing and get it down here, you were supposed get it here last year. Do it before you get snowed in again.

Dont know what else to do after 2 decades of grafting?
Maybe take up gardening.

Well, very drivable baring the Helix twinplate, needs getting used to.

I managed 400 miles on £120 to Donny and back, inc track time.
As a daily driver, about 280 miles.

Not only fantastic top-end, but a wonderful shape of the graph as well!

4000k to 4500k looks mental great results, keep it coming Barbz

I thought you said it had good spool up?

Come on - get it coming in at 3000rpm and then we are talking!!

Ross

really looking forward to see what flea can do with Barbz's monster tomorrow!!!

shall we all start having a guess??

It was run in 3rd gear Ross, so you can take away 200-300rpm if using 4th gear, and then another 100-200rpm when on the road.

looking at the FC performance hall of fame...

it makes REALLY good reading!!

we now have 3 people in the 500bhp club and an impressive 13 people in the 400bhp club!!!!

this is such a fantastic achievement!! well done to all involved!!

So maybe 3300rpm-3500rpm?

For a monster thats pretty impressive! Thinking back to the good old days when a gt28rs coming in at 4000rpm with 400bhp was impressive, this just blows it out of the water!!

Ross

Nah, let's not go down that route. It'll be mental. Like... 560 or something.

Errr... oops.

Where do you get that from? HOF shows 3 in the 500+ range without Barbz or me

Correct, on the road whatever boost i dial in its full on by 3.5k in any gear, and she's rampaging .
I had a couple of 2 bar overboost mishaps whilst setting up the Apexi and O' My God! , that felt nuts !

Just look at the spec of the Z06 LS7 vs mine..

Z06 7.0L
503bhp
470trq
1.4 ton

Vs

TI 2.4L
460bhp
360trq (Heartbreaker figures)
1.3 ton

Great work, very impressing..

Hi Barbz, sounds really great.
Congratulation to your results (as always, if you are starting a new project :-) ).
I think that a big advantage is using the new GTX3076r, too.
We in Germany have direct comparison between the new GTX3076r and the older GT3040r with same exhaust housing 0,82AR in the same car, same spec (Delta Integrale).
Result: the new turbo spools a bit quicker at more top end power. Bespoke Delta Integrale makes easily >500HP!
We think that even >600HP should be absolutely no problem with this turbo.
To the downpipe – bigger is always better at turbo engines :-)
But a 3” exhaust should be enough for 800whp as well – only difference is, that you will lose some efficiency, because you will have to compensate the additional backpressure of the downpipe – means you will need more boost to get the same results as with your 3,5” pipe. Therefore I would prefer 3,5” as well :-)
Another big thing is your manifold – I love it. It looks good and has in my eyes best pipe size for good response and top end power (36mm ID).
Mine has 34mm ID only and I think that I will get problems to get most power out of my GTX3582R – my goal is to get >=650HP – we will see next year.
I think, my engine (E85 conversion with very big adjustable fuel pump, 1200cc injectors, blockguard, very strong M12 studs, modified hydraulic lifter oil bores for higher revs etc.) should be able to do this… only problem is to get the gas through my small manifold :-(
Another good thing is using the original ECU – In my eyes this is a better way than using free programmable ECU’s. There are too much variance like starting at low temps and so on to reach the attributes of the original ECU.
Keep it up, Barbz and Flea, I love it!
Juergen

Alright mate!!

i got my info from the dyno table in the traders section! i included Barbz in there as he is running an FC Performance map... Just Flea is too lazy to update it

Also, today is the day!!! good luck Barbz and flea!! fingers crossed for a brilliant result!!

+1 - could be very exciting

I can't wait until I win the lottery, really looking forward to my own 500bhp coupe!! Well done guys!!

Thanks,

Wanted to take a different approach this time round as I initially purchased a GTX3582 on a 62ar turbine housing but returned for a GTX3076 82ar.
Why?
I would of needed to push the boost threshold to enjoy its benefits.
Hence, i had set myself a max boost limit not to go beyond 1.8bar.
My main goal is to achieve the broadest powerband as possible rather then chasing a high power figure, for power figures sake.

The manifold is proving to be a real gem in the equation

On my current setup it proved to be a major limiting factor, so in this case the size was critical

Sorry guys, rain stopped play . Rebooked for next week now

gutted

But keeps us wanting more for next week!!

Next week it will probably snow!

Flea, are you sabotaging the weather so you don't have to face the beast?

Flea you will have to invest in your own RR mate and not have the weather hamper you. There are so many grown men just about to wet themselves with excitement over Barbz's puddle jumper! Just so happens i know a man who sells them. I've just taken one over to Austria the other week.

we need some vids aswell. would like to see it on the track

The dyno is not the problem Marco (I know Gerry btw ), I have pretty much unbridled access to the dyno I use. While I could tune any car exlusively on the dyno, I don't like or choose to do so because the road and dyno can be dynamically very different. This is even more important as the power increases and the variables become much more demanding. Ultimately most cars live and work under "tarmac" conditions, therefore I ensure that every single car leaves me prepared for this state.

You mentioned you car on Motec, if you need any advise/tuning then let me know as I am au fait with all the common standalone ECUs such as Motec, DTA, Emerald, OMEX, Megasquirt etc, and I also map Unichip. These ECUs are really very simple when compared to dealing with a factory ECU (which are infinitely more complex), and rightly so as they are commercial systems and are required to be made user friendly. Let me know your current spec and I'll advise accordingly. Certainly if you are on the same GT2871R 0.64 turbo then turning up the boost will not give you any further power as you have already reached the flow limit. There are many turbo options, and they don't have to mean any loss in response if specced correctly.

The start of this coming year I am launching a new enterprise that will move beyond Italian cars. I already tune many, many other cars, including race cars e.g. M3s, VWs, Caterhams etc, as some on here will know. Of course the Coupe is still very much on my own personal radar, and 2012 will see my final solution!

Hi Barbz,
I myself varied from a GTX3076 0,82AR to a GTX3582 0,63AR as well. There were some posts in web about a mismatch of the GTX3582r with a too small 0,63AR, which made me unconfident. Posts said that the 0,63AR is too small to handle with the big GTX compressor wheel.
Nevertheless I doubted this conclusion, because there are a lot GT3582r with 0.63 AR, which do proven >600HP – I thought that the GTX compressor wheel won’t need as much turbine revs to get same power output as the old GT compressor wheel. Therefore the GTX35 with 0.63AR should be able to make more power than the old GT35 counter part and more power than mentioned by Perrin, which did a test with a standard Subaru engine with bad VE. He found, that the 0.63 AR was too small – I could not believe this completely.
Link: http://forums.nasioc.com/forums/showthread.php?t=2110277
Meanwhile there are other results from Germany like this from a well known German tuner:
http://www.c20let-forum.com/viewtopic.php?p=905896&sid=eb1cf7b842a89909bf06aace0c1ce3d5
700HP with GTX3582R and 0,63AR at 2l engine and satisfying boost response at 2,79bar.

Therefore I decided to order the GTX3582R with two housings 0,82 and 0,63 and to start with smaller one...
A very good friend of mine started with the GTX3076r 0,82 - with very good results so far...

Good luck, keep it up, Barbz
Juergen

I read this article, thats what put me off the GTX3582

Cool

I recommend you go for a full 3.5 inch exhaust system as the 2.4L suffers back pressure issue's at the topend.

Manged to twist Fleas arm and get in for Thursday.
Moment of Truth is almost upon us.

We all look forward to this...

Flea thanks for that i'll catch up with you soon. Makes sense too mapping on the road so i see what you are saying. Only problem with car like mine is they are not road legal so it would have to be done at a track session i guess. John at Extreme has already done a few when we rebuilt my engine last. I think i need the manifold first then see where we are at with everything before we go changing turbo's. Car is very drivable just now and i have to say no slouch but i am always looking to make it that little bit better.

Sparco- is your turbo externally gated?

http://forums.nasioc.com/forums/showthread.php?t=2110277

The back to back testing of GTX variants vs GT's makes a suprising conclusion.
Also take into account that Scooby's have a very laboured pipework route for their FMIC setup, which induces higher than normal pressure drop across the system, leading to slower spool .

Beware...........HIGH BOOST HERO'S

Looking forward to the results tomorrow.If the diff holds in the box then im sure we will see a new winner.
Dont forget to give me a running commentary Bruv.

Flea..Chris in the Corvette did say Barbz's was quick.

If im honest Chris was realing me in on both the main straights at a fair rate.But didnt have the minerals on the corners.Or the grass in my case .
But think Barbz held him off.

When i went in the Vette it was definitely the quickest thing there on the day.Just didnt feel quick.

Barbz no it's not but i'm assuming your train of thought is that we switch to an external WG and at the same time change the manifold, yes?

The GTX does look like a very nice piece of kit.

Just FYI i'm running 450bhp with just over 400 lbs at 1.7 bar just now on the GT2871R. We have also changed the pipework to shorten it dramamtically which has made a big difference.

@sparco: which pipework do you speak about? Thanks, juergen

Well, if you going down the manifold route, then yes.
Do you have headwork?

We were the first to use these units on Jbt's (GTX3076 ext wg) and Angelo's (GTX3071 int wg) with awesome results. They do exactly what the say on the tin, min 10% more power at the same boost. Billet wheel Turbo's are the way to go now and you will definately benefit from a GTX unit.
What revband are you using on track?

Nothing wrong with trimming the lawn a bit and scaring the wildlife.

Will keep you in the loop for sure

Good luck tomorrow fella.

Thanks Bud.

Looks like we may have snow out west?

Magician - work your magic tomorrow.

I'll try and phone and annoy you tomorrow.

Ross

Hope not!Only in your case!I'll have a look and report back in a sec.

*40% chance of rain in and around bristol between 12pm and 4pm...Otherwise overcast...*

Wish I had the petrol to come up and have a look at you monster somepoint during the day

Hang on....25 mile train journey...wonder how much a ticket will cost...

Get it shipped over here Barbz, the weather is perfect at the moment, I've not seen a cloud for about two weeks!

I'm sure Leighton would appreciate the weather, roads and night life whilst working his magic.

What difference has this made Marco.
Also what diameter are you using as Barbz told me mine were too big.

Barbz i'm still using one of your TI stage 2 heads with C&B cams and back on a ported standard manifold. Running a 7800 rpm but it does creep up to 8k when i'm hunting stuff down.

The pipe work we shortened was the intercooler pipes, specifically the one from the drivers side of the IC back, it now goes in a straight line to the turbo. We've modified some of the others too to suit our needs.

To piping of the FMIC – a diameter of 60mm ID is sufficient for most applications…
I did following calculation – up to a gas speed of 0,4 mach the pipe diameter is ok, gas speed > 0,4mach will lead to increased loss.
When calculating the air consumption for 650HP and 60mm, you will get 0,4 Mach (is ok), at 750HP you will get 0,45Mach… (not sooo good any more).
Bigger piping will affect in nothing but slower response…
Juergen

Yes we only shortened the pipework, we didn't alter the diameter Juergen/JBT

Air speed concerns before the last few inch in a forced induction is wasted, it's mass that matters. I'll take slow mass over fast anyday. We've been here before and I'm just saying, no need for an argument. Just think about what the air is trying to do, the mass is there regardless of how fast it's moving but if it's being forced through that's when a delay comes into play.

By the way, great sounding engine Barbz, I'm not dissing you.

The air also has to be compressed. Response is about how quickly you can put the mass of air that is in there under pressure, taking into account where it's going into of course.

Compressor wheel does what it says on the tin if you let it turn.

This is what I did too, straight from the turbo to the FMIC.
How much difference was there? (I never even tried the long-2x180deg-route, so I don't know..)

Not sure Per as we had chanegd a few other things too. You've been in it round Spa with me what do you think.

Just received an interesting text with Barbz new power output, a smiley summary would be

i too have recieved texts..

all i will say it OH MY GOD!!

and well done to all!!!

Fasten your seat belt!
569hp, 448torque @ 1.7bar

Seriously?! That's ridiculous!!

Well done to everyone involved, that's mental!

Great stuff, Barbz & Flea

Fantastic results well done.

569hp.. Ok!! Christ..


What I think? Uncomparable. Your Coupe's a very nice monster that's all I can say.. thanks again for the ride!

Awesome stuff!Well done bud and all involved Think I need to re-evaluate where I want to go with mine after seeing those results.Fresh plans and ideas with you required before I bring it to you next year...

So the question to be asked now is.......where are you going to go from here?What are your limits

Once again.Well done bud.

geezer, nice one Barbz

when you adding the shots of NO2?

top result , Barbz & Flea

Bloody brilliant result!

Look forward to a passenger ride very soon!

WOW, congrats

Considering that mavric got 600bhp on race fuel, to get 569bhp on what I presume is 99ron, is just amazing.

And considering that this is Barbz just finding his feet again, I can only imagine that 600bhp will be broken soon enough.

Nice results Barbz and Leighton

Woohoow.

Only 569? Pfft.




Congrats fella's.

Leight. Do you know how to map MBE ecu's?
Barbz. I've still got that Aquamist kit if you think you might be able to use it. Will give me an excuse to come and see the wee beastie.

I recall that JohnS' Coupe ran 550 on pump fuel, so assuming this dyno run wasn't octane-boosted, we now have a new UK record

I guess it would be nice to see what it would give on race fuel (to try to beat John's 616), but is there any point?

Well done

Holy horses!!!!

JBT sent me a text this evening, and you could sense the shock and awe.... great job! Can't wait to see her on the track.

I have 670bhp on my driveway, but shared between 3 cars

well done barbz all i can say is keep up the great work mate and a big thank you for making the coupes what there are [a massive shock to the expensive toys lol]

Wow - just wow!!! Can't wait for a ride in that at Spa

Well done Barbz, truly stunning result. JBT texted me too, work folk wondered what i was laughing at

LOL! Nah mate, modern day super fuel's are well up to the job.

Thanks

Well done mate that's a mighty impressive result and compared to the Jap boys etc at a paltry boost level. Also well done Leighton for woring his magic once more.

Well done mate,great efforts this year.

And here is the RR graph

More details here

Good results...this is going to dominate those ferraris abd lambos at spa..

Yikes!

the pair of you are geniuses ........should be in a circus show

NO coupe with that little boost should ever be able to create sooo much bhp and torque.......go knock on Mclarens door and show them how it`s really done.

Absolutely fantastic result and what a lovely smooth torque curve too,must be immense to drive with such an even output

All i can say is barbz you best be at spa dude cant wait to see the faces of rich boys look at a coupe fly past!!! top work

Thanks mate.

Thats the plan buddy.

good plan dude i love sleepers

fantastic result for the undisputed king of Coupe tuning!

I'm sure it'd do more than mine did on race fuel too.

Do you miss it John??
What you driving now a days??

Hey Barbz ive not been on here for a while and all i can say is wow the master is at it again.

Ive read the whole thread and its EPIC!!!!

Man! 569hp thats awesome!
Barbz please put some vids here on this monster in action!

Certainly looks like fun

Thats what Im talking about!

..and then a dragrace please!

Sounds nice, the billet compressor wheels really are quiet

Sorry mate,

That was on my old GT3076 setup

Ok, fair enough ! is it any quiter now then ?

Yes, much quieter and smoother.

The loudest thing in the car is normally the passenger... screaming for their life.

I've just noticed this - the turbo is now much quieter than the last one

Going sideways

Okay. I'll amend to 'Screaming whilst looking out of the passenger window'.

Barbz, well done.

Great achievement. You lunatic.
