Spec Twin PT Helped my HCI NA C5Z into the 10s today Clutch was very predictable, took slip, shifted perfect couldnt ask for more today and a new PB for me too boot! Ive got 5000 miles on it now
Last run of 2009 put my z06 in the 10s NA
Made 4 passes and progressively got faster...after my breakage earlier this year i didnt want to get greedy. Was launching at 3500 with a clutch slip while feeding throttle...the last pass I upped it to 4000 with a little more aggressive throttle feed and clutch release. Came out strong as my gearin is pretty good...nailed my 1-2 at 6900 nailed my 2-3 at 6900 short shifted the 3-4 at 6700 as i knew i had a good pass going and didnt want to bump the limiter like I did on the 3rd pass 3-4 shift...on the return road i seen thumbs up from a few friends so I knew I had it
1.63 60ft
7.06 at 99.7 1/8
10.93 at 128.25 1/4
2002 Z06 22,000 miles
Stock 346 short block with heads, cam, intake, RPM diff and trans, spec twin disk clutch which took a beating like a pro today. It was on 26 11.5 17 Et streets at 16.5psi cold GTO spares and MH racemaster skinnies up front. Safe 12.0 AFR 28 Degrees timing (I tuned it)...Im sure with a 1.50 60ft I could get 10.70s and if I powershifted possibly 129-130 mph. Im sure if I removed my sway bar it would help the 60 as well. Drove it there and drove it back...all is well with no strange noises.
Thanks for the look guys!
Track was Coastal Plains Dragway in Jacksonville NC at 230 this afternoon DA was supposedly -800 ish

Kurt...thanks for the update! It great to see that you have improved on your previous times and I am glad the clutch is all that you hoped it would be. I do hate to hear that you are heading overseas though and I hope that all goes well for you. Let me know if you need anything else and have a Merry Christmas.
