A little while ago I had a Driftbox strapped on my car. Driftbox is a GPS based data-logged, which calcualtes acceleration from the GPS information. It's more or less the same equipment as the local mags use.
Anyway, with the Driftbox on my car I managed to clock the following 400m times (with 30cm roll-out):
- 14.02sec @ 164.56kph (60' = 2.29)
Did not have much traction in 1st gear, but still pretty consistant with the times from Calder ... expect the trap-speed was much better here.
and and shifted at about 6000rpm but still lost a bit of traction in 2nd.
Are you talking about every gear, or just 1st here?
i just bought myself a gtech pro timer which came in the mail today
Will be interested to see the times for your car and also the 335. I hope that you'll take it to at least 160kph, and post detailed data ;-)
