I then moved the setting to the 26.95 that the car had set stock. The difference in times was not much if any on the car. First run was 3.7 to 60 and 7.6 to 100. Then changeing to the stock size of 26.95 it was 3.9 and 7.8. So i put it back to the 27.35 and did another pass and it was 3.9 and 7.8 again. da was 2000. So its not much and certinaly not a half second for the differenc in size speed o setting. I always use the launch control on the car and its a 10 speed. I can not dupalcate its repeatability. I can no doi as good as it does either. So for what uits worth.

What's done to your car?

Sorry but I mis spoke the tire size was 285 and not 295. The car has a p1sc procharger and alky control meth injection. Nothing else.

I spin like crazy since I have had my mods done. I had a lower pulley, headers, and cam done. I pull a 4.4 but I’m spinning the whole time. I have about 5k miles on my Nitto 05’s. I have some Toyo888R’s but I’m saving them for the strip. I tried massaging the throttle but I still spin.

The launch control controls spin pretty good with the 10 speed but once the rpm gets above about 3200 it lets go and then it starts to spin again. thats what gives me pause about makeing more power.
