With a best 60 foot of 1.97 on a tire and corrected passes in the 12.1 range at 115mph, it was time for an upgrade....and badly.
I called Andy at ADM Performance and had him order me a Yank SS 3600 converter. It was installed a few weeks later, and was ready to get back to the track.
Weather this time was awesome. DA actually started the day at -46' (yes, negative at 1:30 in the afternoon) and ended up 280' by 5pm.
If I remember right, the first pass had 20-22psi in the 305/45-18 NT05R's and the car spun to a 1.79 60 and 11.93@114.3mph. So the 60 was better even though I was spinning, and ET was better than the corrected times I was seeing pre converter.
After some playing with tire pressures and launch strategy, I managed to get it down to a 1.66 60 and an 11.76@114.7mph. On that pass though, there's was definitely a tuning issue and the car seemed like it was hitting a rev-limiter around 5000rpm in 1st gear.
And my 60's were all over the place, from the 1.66 to 1.85. Not good.
But I'll still take an 11.76 at nearly 115mph for a full weight car with the little GT11 cam.
Now I just need to figure out this tuning issue and get this car to consistently hook.
