I can confirm that for NA engines. My 4000CSQ w/schrick 272 is definatly
slower than stock until around 40 mph, about the same as stock from 40-50,
marginally faster from 50-60 and considerably faster to redline (~76).
Bob noted inconsistant times for what should be a similar car (Ur-Quattros),
An inaccurate spedo cold well be the culprit. That is some of you may be
computing times from 27-71 as I would if I'd trusted my spedo. I used the
tach for my times since it is easier to read full scale and I know 1000rpm
in third is ~11.75mph - hence 30 is 2550rp[m and 70 is 5960rpm.
