Matt Harwood Posted September 19, 2004 Share Posted September 19, 2004 210 @ 7600 rpm, with the right sized tyres, if you can find a steatch of road long enough! Link to comment Share on other sites More sharing options...

I cant get over 7400 at the moment but i may have the 295/35/18's coming in time as opposed to the 285/30/18's on at the moment , i have a long enough bit of road and datron equipment to varify it , i was at 185 befrore the mile at TOTB and that was 1.5 bar Dude:flame Dev Link to comment Share on other sites More sharing options...

dude Posted September 20, 2004 Author Share Posted September 20, 2004 With 295's the theoretical speed would be around 235 !!!!!, of course aerodynamics ansd chest wigs etc come into this quite a lot at these speeds . Dude:flame Dev Link to comment Share on other sites More sharing options...

Matt Harwood Posted September 20, 2004 Share Posted September 20, 2004 Some time back, Ian C and I measured our cars true speeds in their respective 1:1 ratio gears. Ians manual car in 5th at 3000rpm had a reading of 66/67 My auto at the time in 3rd at 3000rpm was reading 56/57 It would be interesting to stick a GPS unit in your car John and see what it reads in 3rd. I need to get out more Link to comment Share on other sites More sharing options...
tbourner Posted September 20, 2004 Share Posted September 20, 2004 3000 revs in 6th is about 90 in mine. Link to comment Share on other sites More sharing options...
Guest N 500 PRA Posted September 20, 2004 Share Posted September 20, 2004 My UK auto was doing a steady 95mph (indicated) @3200 rpm Link to comment Share on other sites More sharing options...
Scooter Posted September 20, 2004 Share Posted September 20, 2004 i think matt's point is that in the 1:1 gears you can directly compare the effect of the two different diff's on the speed and therefore maybe extrapolate from this to give an idea of a auto with manual diff etc..... .......i think i need to get out more too.

dude Posted September 20, 2004 Author Share Posted September 20, 2004 That was measured on a GPS Matt !!!!, if it had the right height rear tyres i reckon it would be 95mph at 3000rpm so thats 190 at 6000 with 1500 left to go = 237.5 mph which woul be about right at the moment its only about 225mph at the limiter Dude:flame Dev Link to comment Share on other sites More sharing options...
Matt Harwood Posted September 20, 2004 Share Posted September 20, 2004 Now go and do the same test again in 3rd @ 3000rpm to get a comparison against an auto and manual stock gearing. Link to comment Share on other sites More sharing options...
