I shot out to Dragway 42 in West Salem OH last night to try and work on my launches with these DR's. Turns out besides being T&T, it was also a Import Quick 8 night. There were more cars than when I usually bracket race. Worse yet most of them ran in the 16-18 second range, so I only managed to make two passes. First race was against a new VW Beetle. He ran a 17.6 with a terrible 1.2 RT, I ran a 14.26 with a .652 RT. My 60 ft. was a lousy 2.185. Tire pressure was 22 PSI. Second race was against a stickered up Acura. He ran a 15.00 with a .952 RT. I ran a 14.31 with my best ever .514 RT. Another lousy 60 ft, 2.165 with tire pressure at 18 PSI. Any recommendations on where to run my tire pressure with these Nitto DR's? My car is basically stock, it has a TPIS Fast Pak, 24# Accel Injectors, bumped timing, Jet fan switch, 160 thermo and cat back. Also has 157,000 miles. Suspension consists of Lakewood LCA's, Panhard, Energy Suspension Poly bushings throughout and Monroe Sensatrac shocks and struts. Thanks
