81Malibag, sounds like she is going to get serious next year. What are going to have for build on your 468?
Pontiac6269, Back when my GN was new I ran it box stock for a couple 13.9s at 98mph. Later I got a threaded waste gate rod so that I could turn up the boost. I put a few ounces of Marvels Mystry oil in a 5 gallon can of Xylene then put it in the tank before filling it with 94 octane Sunoco for a 100 octane mix. All stock yet, we could turn the boost up to 22 or 24 psi ran 13.30s either way. Seems like with the stock turbo etc more boost equaled more heat so it made no more power. Also think it was getting close to pushing the limit of our home brew. Anyway fellow at the track came up looked at my slip and said aint you got no slicks. I said no he said I got some GN wheels with a soft compound recaps if you want to try them. No other changes and it droped to 12.7s at 107. Now with more mods she is still only running 12.4s at 109 but on pumpgas with a methanol/water injection kit. GNs can be fickle but with a scan tool and some patience be very rewarding.
Life is short enjoy your ride. When you turn your car on does she return the favor? Mine's a hybrid burns both gas & rubber.
