What sort of auto set-up is it...transbraked powerglide?
If only we had the $$ to develop a GTS-4 auto to run some times in a GTR, or maybe adapt a glide for 4WD.
It takes a real skill to drive these manual cars consistently down the quarter.
I just had a look at some old data from when we first took the car to the strip...running 11.2 i was loosing 0.6 secs 1>2...0.5 secs 2>3...and 0.4 secs 3>4...thats 1.5 seconds during the run when the car is not accelerating.
It may be a matter of hiring the track to get more practice and runs under my belt as ive only done 18 drag passes total and seemed to be only getting the hang of it with the last 6 or so runs.
If your car is ANDRA tech'd would you be interested in coming to our test day?, as we need 10 tech'd cars to fill all the spots.
