I have had my GTD/40 for a little while now, and have always felt it was seriously under-geared. So this week I went out onto a quiet stretch of road and made some measurements, road speed as indicated by GPS versus engine revs, in increments of 1000rpm. The results are attached - a screen shot of an Excel sheet. Blue figures are extrapolated (my passenger started to yell blue murder when I exceeded the speed limit...). Although I have quoted estimated road speed at 6k revs, no chance that that will happen any time soon.
The spread is nice and even, but the absolute speeds are, I think, ridiculously low for a GT40. Its a mildly tuned 302, with bags or torque. The box is a Renault 369, car running on 265/50x15 wheels.
Anyone know what final drive these boxes had? Are my figures significantly low? Any other comments?
Thanks
Peter
