It's an ATI convertor, but was cut by PTC due to time constraints...there was nothing found askew. I know the weather conditions will have a great effect, but even in good air and track prep we saw a loss of launch performance and it has never improved to date...seems to be stuck in the 1.52 range. We did notice some tire slippage running 18psi and I recently went up to 20psi...did'nt seem to have any effect on the 60' times. As for the driveshaft I don't think there is a great difference in weight between the two.
Here's a for instance time slip. This was in pretty good conditions and before the carbs were worked on...despite the poor launch the car goes faster than it ever has before at every other point on the track. I remember these passes because the car felt like it was just driving off instead of hitting the tires hard and snapping the front-end up. If I can figure out whats going on I believe it will run 11.20's in decent air. This pass the car had the same Calvert SA shocks that it wore when it went 1.45 - 1.47 60' times...it now has DA shocks on the rear, but I'm not working the back hard enough for them to have any effect atm.
