Please review my runs and make suggestions I have an 01 Z28 M6 with Jethot LT into a hooker aero chamber kit. The rear has been changed to a 4.10. The car has 78,000 miles on it. My goal is to get the car well into the low 12's. Here are the times from my runs this weekend
60 feet 330 feet 1/8 mile 1/8 mph 1000 ft 1/4 mile 1/4 mph
2.107 5.847 8.861 81.92 11.409 13.587 104.44
2.206 5.912 8.97 82.18 11.578 13.748 105.13
2.209 5.919 8.99 81.89 11.601 13.774 104.97
2.122 5.873 8.971 81.33 11.592 13.778 104.39
2.206 5.919 8.965 80.47 11.565 13.944 91.03 Misses 3rd
2.171 5.892 8.996 80.14 11.566 13.788 102.75
2.39 6.059 9.051 82.79 11.567 13.786 99.5
2.0438 5.7105 8.7584 83.1 11.3 13.55 105.77
I know the 60ft sucks but I am taking it easy until my 12 bolt arrives leaving the line at 2,500. Once I get the new 12 bolt and my new Mcleod clutch if I'm launching hard on drag radials are 12's within my reach given my trap speed? What trap speed do I need to reach low to mid 12's?

I have had zero luck launching hard on DRs. My best 60s are a very aggressive clutch slip launch, 4K or so to start & ride it most of the way thru 1st with increasing throttle. With a 4.10 gear the other thing I needed was a cam, I kept running out of RPM in 4th.

z28---man your 60 foot times are pretty good...im not exactley sure why youre not going any better than 13.5....i ran my 98 SS manual with a k&n filter and exhaust through at 13.53 @106 with a 2.26 60 foot time...i need to get that 60 foot time down and ill be 13.4 or 13.3... especially with longtubes i would think that you would be trapping higher too...maybe your car just needs a tune up?

The tune up was recently done when I had the LT installed. I'm wondering how much never having the PCM tuned after the LT install is hurting me. I was thinking that with that trap speed I should be able to break into the 12's.
