Cool Hp no problem.

Craig its all theory untill you get the car going i did say calculations it was only few years ago when the nascar boys said that for every mph over 200 mph you need another 10 hp to get one more mph.
it sounds cool to say it is capable of doing it . I have a gt45 turbo on the shelf its rated to 1000hp so all i need now is a pair of gangollies to go with the turbo. if i wanted to go 200 mph i guess i could build a cobra to do . the celica got to a 126mph in 400 meters so what can happen over several thousand meters i know there is a big differance between 126 and 200 but at least i am over 1/2 way.
Craig did you ever work out how fast you beast went in top on the limiter now lets see from memory you had 3.0 gears and a 285/40/17 or 45 rear tyre top gear in a glide is 1 to 1 i guess revlimit 7500

so a rollout dia of 660mm circum of 2072mm thats 2500 rpm x 60 = 150000 rph x 2.072 mtrs divided by 1000 = kph of 310 not far from 200 mph 193 mph that is with a 40 profile. with a 45 profile it would be 324 kph or 202.5 mph. its all just theory i have not allowed for slipage craigs trans builder would be the one to tell us that number.


please Paul no corrections on my maths.
