Went to the track last night and managed to get 3 runs in, before I was told thats it until I get a helmet , which actually made me laugh.
Best run
RT: .244
60': 2.106
330: 5.885
1/8: 8.952
MPH: 80.81
1000: 11.587
1/4: 13.810
MPH: 101.62
The other 2 runs where 13.980@101.13 and 13.861@101.20.
Since the last time, I've gone to 15% OD on the blower, which from what I'm seeing is hurting my car. At 10% OD I was getting the same times but trapping faster at 102.5mph. My ACT's ended up being about 15 to 20 degrees higher at the top end, which means more timing is getting pulled.
At 10% OD I was seeing about 13.2 pounds of boost at peak, with evidence that there was belt slip, and it was mentioned to me that my 5% JS pulley may have become polished with the belt slip I had last year.
At 15% OD I was seeing about 15.1 pounds of boost at peak, and no evidence of belt slip.
I think that 15% may be too much for the stock inlet and/or blower at the track, but its alot of fun on the street . I'll probably drop back to 10% next time at the track.
I've also took the plunge and turned off my knock sensor and I'm running the car with 26 degrees of timing with 94 octane fuel. All is good so far .
Unfortunately, on my last run I heard a clunk from the rear of the car about half way up the track that I need to check out. The car is running fine and doesn't feel any different, so I'm hoping its nothing.
Thats it until next time....

Edit: I also did one run with spinning up the tires before staging and not a wit of difference.
