New pb for s366 4.8
#5
the best I can describe it is that its running like its N/A lol. Early this year I was running 1.54-1.56 60fts on stock rear shocks leaving on same boost level. Switched to QA1 double adjustables in rear and have yet to find the sweet spot. Went stiffer with them today because last sat I was spinning to a 1.61 and ran 10.99 at 121.9. Well going stiffer on them didn't help and roasted them through 1st, and spun the 1-2 shift on slicks and ran a 11.15 at 120.8, the log showed I never went 100% throttle except for the 2 step. Backed the shocks back down, and truck went 10.92 at 122.3, but even on this pass it spun right on launch and I let out, then punched it again. I would have to think that letting out before the 60ft, would not be netting any better then 1.6s on this pass. The time slip printer broke today and they were just writing down 1/4 time and mph and that's it. Looks like im only back halfing 22-23 mph. could be that im only running 12.5 degrees and rich afr. Truck has always kinda worked this way. I feel like if I can get the 1.5s back should have a bottom 10.7 in it at 122.
