New Track Times for my Twin 67's; 9.16 at 146.197
Finally got some good weather - at least for up here. Track was great both Saturday and Sunday, well prep, weather similar on both days.
Saturday was a loss as I had some serious traction issues. Every pass, 1 to 2 shift would cause the SS kick the rear end out and had to fight the car the entire pass. This got really sick'n. Total of 6 passes on Saturday. Best of 9.62, with a best of 1.41 60'.
Sunday. We decided to change back to my old Hoosiers - 30x10.5x15R vice my new M/T 29.5x10.5x15S.
1st pass on Sunday: (Same set-up as Saturday except the tires)
60': 1.397
1/8: 5.926 at 117.568 (my 1st 5 second 1/8)
1/4: 9.266 at 145.724 (new best)
2nd pass on Sunday: (Increase 2-step to 3900)
60': 1.336
1/8: 5.840 at 118.283
1/4: 9.166 at 146.197
3rd pass on Sunday:
Found the limit of the tires out the hole on boost - set 2-step to 4100 and it blew the tires off. Oh well.
OH BY THE WAY - THIS WAS ON 8LBS OF BOOST We are getting close to our goal of 8 second pass on 8lbs of boost. Next race in 2 weeks.
Big thanks to Joey (my sponsor/builder/tuner) and Ryan (best damn helper/pit crew).
Here's the time slip

Excessive AutoSports - Joey's shop - no one help us on motor build except W2W with the cam and LS1Tech in general. Read every post I could get my hands on turbo builds. Joey was the final say. Great build - you think .

I tell ya. I couldn't believe the difference. After fighting with the SS for the last 3 weekends, to finally get a glass smooth run was great. The 1.33 60' carried the tires for 40-50' about 4-6" off the ground. Felt absolutely great !!!!
I agree, every car will work differently with the same tire - in general.

Never have really dyno'd the SS on 8lbs. A guess would be 650-700rwhp. The twins really spool up fast - by 4700rpms I'm at full boost. 14lbs = 850rwhp from 4700 to red line.
