i was there wed at 730 for fuel (methanol), , the temp was good (low 40s) but the air was damp and traction will suffer because water dragged up wont dry ( and few slick cars to help out the grip) and with the small turnout they usually end the night early like just after 9
a friend had done a turboed 3.1 in an 89 and we managed to put mt 28/10.5s et drags under his with a little banging ,m/t makes a 28x9 drag that would fit no problem
hard to compare your chassis to mine or what ive done on other nights to what wed nights track conditions were , but i usually managed 1.5s at night on 255/60-15 mt radials aired at 20psi but i'm trapping over 115, and over 90 1/8th (fast as i can push it and not get the boot) , i also pit with the faster slick cars (lane 9-10), try not to run with or right after the street cars(they run in lanes 1-5) as they drag a lot of water to the line (because many are too dumb to drive around the water box) ...daytime the grip improves greatly
and if your blowing the tires away at 5psi , then launch with less boost learn to pedal out of the hole , with the mickey radials i used to limit launch to 6-7 psi at night usually leaving at 3psi, with slicks i could manage to hook a 12psi launch
are you planning on making it this wed night?
