They dont use 3mm thick pipe

They use the same thickness as the rest of my intercooler pipes

You got to bear in mind that Prospeed exhausts also speialise in intercooler pipes and custom induction pipes, so they know what they are doing

Ben

cool, id be interested to see the finished product benny, they arent that far from me, even with crossing the bridge, so may end up taking a trip abroad in the new year.

Bit of progress today by painting and reasembiling the lower rad support

painted

fitted

Ben

welldone benny,, keep up,

Got my pipe made up

pipe

Fits very well, need to reassembly it propely tomorow and
give it a thougher test on the weekend

Boost take off added

Ben

nice one benny, i like the little ridges to keep the silicon pipes on,

nice one, am getting mine done like that for my evo intercooler.

Just spotted this and by coincidence mines booked in next week to get some hard pipes made up

Bit of weld does wounders

Ben

Bear this in mind, everyone who i've seen who runs a evo
cooler with there pipes under the rad, they are extremly low

The only way at the mo is/what i've done is to modify the rad support

Ben

its been modded to fit the coop, cant see the pipes causing too much trouble. touch wood!

Touch wood also

I'll post some pics tomorow when the coupe is back together
and take some measurements as well

Ben

did you use stainless steel pipes?

Thin gauge stainless pipe, not the same as you would use
for a exhuast.

Ben

Benny you getting the lower pipe made up at pro speed?

Good job done!
Will consider the same if I ever do the FMIC route.

Yep charlie at prospeed did my pipe, though i did make up a protype for him to copy

Ben

Right then



Fitted it finally this morning pic

Only went out for a quick drive this morning and the difference is actually noticeable

Bearing in mind i run a 64/ar gt28rs, i'm now getting positive boost under 2k and full boost well under 3k and
the main thing its on torque/song around 2.9/3k



I'll give a better write up tomorrow with figures

Inmagine what it will be like when i do the rest of the
pipes

Ben

Took the coupe out this morning for a thougher test

First impressions were the coupe felt a little more responsive low down, and seemed to want to get into
positive boost all the time regardless what gear i was in

A few tests were performed

In 5th gear at 1000rpm WOT foot down i measured

Positive boost at 1450rpm

Came on boost( 1.3bar) 2850rpm

And what i felt, came on torque roughly 3000/3100rpm
previously came on torque 3250rpm.

Measurements

The original route from the turbo to the intercooler was

147cm long and has 5 bends in it

The pipe i made up has 2 bends in it and is 51cm long.

I will be making the rest of the induction pipes into hard pipes so keep watching



Ben

Very tidy job Benny

Cracking sucess if i say so myself

< waits for a repliy >



Ben

I would be interested to know why Pro Alloy and Phil (was it highwayman originally??) chose that pip route if such a shorter one was possible.

The longer route keeps the pipes level with the bottom of
the intercooler, which is fair and makes it plug and play

My route is dramacticaly shorther with less bends,

but mine requires modification to the rad support and it sits all of
a 1/2' lower than the original

Come the end of January i'll see on the RRd if it does improve spool up

Ben

Getting my hard pipe made (insert sexual pun here) up as I type this, so I'm wandering around Cardiff freezing my nips off. Will upload some pics when I get back later!

Nath

my pipes...



I got some of lag. in runing when squeeze the clutch when the rpm's down to 700rpm and 900rpm's the back.. the lag I think I will settle with more pressure to turbo. what can I do?

my material:

filter box K&N
Dump bailey dv26
FMCI
stock Turbo
G-tech1

in future:

g-tech2
gt2860rs
walbro 255ltrs
exhaust pipe 70mm
fpr

great job benny.will be following your progress

Cheers Zonta

Hopfully when i get the top pipe made up and get it checked,
i might offer them in a GB

Ben

Ben

orcale i think you will find its down to running lower preasure but also the main thing is the air flow as you need to fill the intercooler and on the standard turbo it will take longer as it flows less air hence more lag.
so really need a bigger turbo
on the plus side by having the fmic you won't really get much power increase as you don't have the air at peak to make more bhp but you will make your torque as it will have colder air with more oxgen in it so you will get a higher torque read out but it will be at a higher rpm because of the lag.

Yes peanuthead, I see that the only solution will be replacing the turbo. thanks for your help. I will leave soon and later replace the turbo, and there must be good.

thanks...
