For those wanting a free stopwatch for their stopwatch-less Symbian phone, I found this: http://www.racechrono.com/about/?lang=en

Works with GPS too! So I'll be checking this out tonight on one of the many MK circuit configurations.

Oh and check this - "performance tester. With the Performance Testing feature, you can test your vehicle’s acceleration. You can select from various different tests, for example 0-100 km/h acceleration test and a quarter mile test. Remember not to try these tests on the public roads!" :- http://www.racechrono.com/manual/?page_id=23&lang=en

Sweeeeeeeeeeeeeeeeet! Ooh I'm all excited.

Surely it depends on how quickly your GPS updates?

Yeah, probably too slow for an internal GPS - 1Hz sense instead of 5Hz sense. It'll be a gimick probably, but nevertheless I'm struggling to hold back the sex wee until I get home tonight to download it!

Just look at all those sexy graphs!

I'm doing it! Tonight it's gonna be played with whether it works well or not, that is if it's not raining which it is currently

nice n sunny here iv downloaded the track thing to my n82. only prob is we cant get 3g up here in the hills.

Could you cheat? Get someone in the back seat to throw your phone to the front of the car at the last moment! Could shave 0.1s.

welformed, the laws of physics prohibit that, so it wont work, einstein's general theory of relativity!!!

I don't get how it works? Is it off the GPS signal?

Surely you need GPS on your phone!? I have an N95 so I THINK it will work on there, someone correct me if I'm wrong!

me cheat? noo.. wey its working, had 6 sats.. took it for a run but couldnt do it as they were to many cars n had to slow down, plus its all up hill got 120ish out of it but wasnt pushing it. also i need to set me dump valve proberly. al have to try n find a better spot.

n82 is the same as the n92 but smaller, cant see why it shouldnt work.

I still don't get it lol!

in the settings change the gps receiver to internal gps

Ah cool I shall go home, download it and see what it does!

Already researched that bit http://www.racechrono.com/manual/?page_id=56&lang=en

Just charging my phone up. Seems to work ok. Sadly on foot I could only manage a 0-10kph performace test!

my traveled route was 15 mins. think 164kph was my highest but up hill n cars in the way.

I did 320 kph up the motorway the other week, according to my AVCR. Do you think it's lying to me?

nice bit of kit uv found, probs have to pay for it after a month.

somethings not right, dont think me mob is.

Actually it's still in beta. So it just says download the next beta version in a month, hopefully still for free, but dependant on how well it works on an internal GPS, I'd probably pay for it anyway.

found 185kph on me track time

Well iv installed it so im gonna have to give it a go!

I just about make 100mph in third. Strange that Autocar were running to 7000rpm on their test car, which equated to a max 108mph in third, and 72mph in second. My Racelogic Vbox Mini tells me i'm getting 68mph in 2nd, and I can just about nudge 100mph in third. How can rev limiter be raised?

It can be raised using a custom chip for the ECU - but on a standard turbo you wont benefit much from raising the limiter.

Has anyone attempted a group buy for Racelogic PerformanceBox. They are only around £330 inc VAT. I'm sure we could get a minimum 10% discount on an order of 10 bringing peice down to £300. This unit updates at 10hz so very fast and accurate. Clicky http://www.performancebox.co.uk/overview.html

On the subject of meaningful tests, I reckon a 30-70 in any gear, plus 50-100mph in fifth. Anything over 100mph is too risky unless we can hire out a runway somewhere.

My contribution is:

Std 20VT 1997 95,000 miles

30-70 through gears:- 6.2sec,
50-100 in fifth gear :- to be added
60-100 in fifth gear :- 16.82 sec

i can get aroundt 100mph in 3rd and my car is running about 270bhp

BHP won't determine maximum speed in each gear, rather just how quick you get there.

Gearing and max rpm determine max speed in each gear.

If you cant quite reach 70 in 2nd or 100 in 3rd then get some slightly bigger tyres...

I had thought of that...what size do you recommend?

i hit the limiter in 3rd at a 108mph with the standard rev limiter and now 110mph with raised one.

I had 215/35/18 on 18" wheels, I considered trying 225/35/18 or 215/40/18 but I have no idea about sizes on standard wheels!
