OK, Old car with 0.89x4.857,& 28" tyre= 147mph...about 7600rpm. Chassis car that I crashed, 147mph,w'0.82x4.857 & 28"...about 7000rpm. N/A engine in old car not yet run but geared to run about 7000rpm @ 120mph...ie 5.42x0.89 & same 28"tyre. MPH=(rpm x tyre radius) divided by (final dv ratio x 168) EG: (3000x12.5) divided by (4.125x0.89x168) Equals 60.8mph.....clear as mud?

Hey Stevey, how about some info on your car. I believe it is turboed now? Does that mean those 46IDAs are back under your bed? Is the engine the same only turboed? You know, cam,compression,boost,best times(both n/a & boosted).Your car still has style after all these years!
