ok guys looking at a 91 GTA with a stock 305. not sure if it is rated at 170hp or 210 (which engine came in this car) it also has dynomax headers and ehxhaust other wise stock. but it also has a paxton supercharger on it. how much power (ball park estimate) would this engine make? and what is a normal amount of boost to run on a daily driver with this setup?
thanks
Tom

 

you have a TPI unless someone has altered it. This means you're rated at 210 and w/ the hedders lets say 225 HP. Add a blower...prolly another 100 HP (lets say approx. 50% increase) So about 325. You probably have more than this, but this is the "lowest" you'd have IMO. 325 HP is a very nice # BTW

 

thanks. this sounds like a very nice street car. i hope that everything works out and i get it.
thanks
Tom
