I have an 02 Trans Am with TR224 cam and full bolt-ons as well as a TNT F1 kit. I have been testing and tuning the car for about 2 weeks with a 100 hp shot. The car has a little over 65,000 miles and I would like to step up to a 150 shot. Can anyone offer some advice on what to expect and what size jets to use?

Stock Fuel pump? You might want to look into a Racetronix Fuel Pump if your still stock. Pulling a few degrees of timing wouldn't hurt either.

I have been told that the tnt f1 kit (150) shot is too much for the stock fuel pump. thats why im upgrading. Check the sponcer section for a group price on the fuel pump..

I was told by one of our sponsers that tunes our cars, that with a 150 shot on a car that's already making 400 or more rwhp NA, your engines on borrowed time. The hyperutictic (spelling?) pistons can only handle so much hp. He said that people get away with it by using race gas and lowering timing more for so long, but that in the end...boom.

I do have the racetronix fuel pump (need to add to sig ) and am considering lowering timing to 25* using a Predator. The car makes 385 to the wheels N/A. I am hoping for trap speeds around 125 mph+ with the 150 shot. Am I clear for takeoff?

Oh then you should have no problems then. Race Gas is better than pulling timing. If your worried you can try both and work from there.
