It calculates to 381rwhp which is about 15-20 more than rolling road measurement for my car......BUT sinse the RR session i have fitted the pro alloy intercooler and the hard pipes, which might have made up the small difference in figures? Plus i was not given my speed trap time but i read my speedo saying 125, which could be anything from 120-125? It would be good to put her on the rollers again to see if the nubers add up?

I'd say more like 120 or slightly less. At 180mph mine was reading just under 200!

120mph gives you 337bhp at the wheels.

At 176mph at Brunters, my speedo reads approx 185mph which would indicate it's 5% out. So you are right, 125 on my speedo would be more like 120ish.

I just re-put the figures in and 337rwhp is more like it, with 120mph and an estimated 1/4 mile in 11.36 (which proves i could probably do it about half a second quicker maybe)!

Adrian, did you have problems?

i think anything with more than 500bhp at the wheels just couldnt get any grip all the way down, I could wheelspin in any gear, at first i thought i'd broken the clutch.

I turned it down to 500bhp and 400ish lbs and it ran a 12.6. I only did it because the tyres were shot, in hindsight it would have run much better with new tyres.

Maybe i should get a pair of wheels just for this stuff and put some sticky slicks on.

On the way home on the hot tarmac road it didnt spin up when i floored it in 3rd.

Na, only do that with you in the car

As I recall I got 160 at Brunters and the speedo was bang on.

[NobleGuy]

My speedo's 10mph out at 100.
