On my 11.24 pass the 60' time was a 1.66
My best ever 60' time was a 1.63
I have a pile of timeslips with 60' times in the 1.63-1.69 range dating back to 2003. My dragracing chassis setup hasn't really changed. I've always just lowered the torsen bars, clamped the springs, set the rancho shocks on 9 front/9 rear and run wore 285x75x16 BFG AT's on stock aluminum rims. I only launch with 10-15 psi of boost (measured at the compressor housing) and I always run in T/H mode with the Elocker on and the copilot on kill (locks up as soon as the allison gets into 2nd gear).
I even tried a set of 285x60x17 toyo proxes on 17x8.5" H2 rims but I couldn't get any better 60' times with them that I was getting with the BFG AT's.
