I did a 14.7 in the quarter mile in a stock 85 gn with a larger camshaft and a cold air kit. I had old Good Year Eagle tires that were hard. The car was not able to break the tires loose. This was last year.
This past winter I put on Poston Headers, high flow cat, High low hooker exhaust,adjustable waste gate solinoid and hot wire kit. The car now is totally changed. It scares me. When I punch it now to floor the old tires just spin until they get hot enough. Needless to say that new tires are on order. This will keep me happy for a couple of years until my engine warranty is up.
Next-TA33a turbo, 36pound injectors, adj. fuel reg. and a walbro fuel pump. I should be into the twelves. Brad
