Supra-Dupra Posted September 28, 2006 Share Posted September 28, 2006 180 given enough room Id be hoping for. Considering I got 167 when stock and that felt like it had more left in it. Have never got that high since Link to comment Share on other sites More sharing options...

Have never got that high since Surely you'll only go faster if your peak power goes higher up the rev range? Link to comment Share on other sites More sharing options...

Will have to wait and see what someone else with more experience says but Id be expecting a small increase tbh Link to comment Share on other sites More sharing options...
Supra-Dupra Posted September 28, 2006 Share Posted September 28, 2006 I felt when stock I could had touched 175, so 180 wouldnt be expecting a huge increase. This is going by a digital speedo and rev display. Link to comment Share on other sites More sharing options...
scott23 Posted September 28, 2006 Share Posted September 28, 2006 wit 273rwhp and 320of torque has got me 171mph or170 on speedo head boost only at 0.6 thats on stock twins wit fmic my speedo has 200 mph marked up on them so thats my aim Link to comment Share on other sites More sharing options...
Gaz6002 Posted September 28, 2006 Share Posted September 28, 2006 Depends on rev limiter, aerodynamics and mods carried out to get to 400bhp i'm guessing. My standard supra has been on the dark side of 165 on speedo on a very private stretch of very private road. That was at 5700rpm so theres more to go but factor in the speedo error and i'm guessing mine will go to about 170ish, maybe a little more. IIRC 400RWhp should get you close to 190ish? Someone correct me! Link to comment Share on other sites More sharing options...
Homer Posted September 28, 2006 Share Posted September 28, 2006 Been waaaay off the clock and seen well over 180 on the gps thats with only 360rwhp. It took an enourmous amount of test track to for the last 15mph. Link to comment Share on other sites More sharing options...
Thorin Posted September 28, 2006 Share Posted September 28, 2006 I've seen about 185mph, well about where 185mph would be on the speedo if it went up that far, at BPU Private test track. Link to comment Share on other sites More sharing options...
tooquicktostop Posted September 28, 2006 Share Posted September 28, 2006 I have heard before that the difference in 170MPH and 180MPH then 190MPH etc needs a huge jump in BHP because of the aerodynamics and to break the 200MPH barrier as someone mentioned above requires a very special car indeed, may stand corrected Link to comment Share on other sites More sharing options...
chris aka fonz Posted September 28, 2006 Share Posted September 28, 2006 Im sure ive read that 600 hp will see 200 mph , but would that be rwhp or fwhp ? Link to comment Share on other sites More sharing options...
chilli Posted September 28, 2006 Share Posted September 28, 2006 I think before when it was discussed, something around 500-550 @ wheels should see 200mph was the general opinion IIRC. I'd reckon it should be possible to get close to 190 with good bpu some people have said 181 is possible stock, so I've read somewhere Link to comment Share on other sites More sharing options...
