What tire pressure did you guys figure out for the drag races, I could sure use the input, got test and tune on Friday. I'm running the M&H 390's, is 22lbs. a good place to start?

Damn, 180's would drop my ET's to 8.20. Gotta get some tires...eddie102870 said:1.81 was my best most were in the 1.80 ish bogged a few times, needed to launch at a higher rpm.
Trainman said:My best 60 foot times were with 17 lbs in my M&H 390's. I am naturally aspirated and do about a 2 count burnout...1001,1002 , get it. I also have a Hurst Line Loc. I found that 15 lbs was too low, an observer said the side walls were buckling. I leave at about 2800 rpm and I have Caltracs.
The thing is, you can't shift worth a crap!!!Trainman said:RC , 2004, with 4.56 gears, Fidanza flywheel, Centerforce clutch , headers, Magnaflow, Volant Ram Air and DC tune. 482 RWHP, 526 Ftlbs. Best 60' 1.825 average around 1.86. If I try to leave @3000 or more then 60' jumps into the 2.00 range. I am going to try and get my differential angle set at -2 degrees and maybe go with some of Justins adjustable shocks to get in the 1.6 range.
