Modding my GTP

[NewPrixOwner666]

Im looking into modding my 98 GTP soon, and was just wondering, if I followed all the steps in the post http://www.grandprixforums.net/f81/safely-modding-your-3800-powered-car-17482.html to get it to a 3.4, about how much horsepower would it be adding to the base 240?

youre more than likely making about 215-225 stock depending upon how healthy your motor is. with a 3.4 setup youd be hard pressed to get 250 whp with a fantastic tune with higher timing.

usually to run low 13s (13.0-13.3) you need a setup capable of running a 3.2 pulley with at least stock timing, but probably more.

short answer 20-35 crank HP depending on your supporting mods and tune...........

Stock I'd say 200-210 FWHP. Basic 3.4" setup I'd say around 240-250 FWHP on a good tune IMO.
