godofthunder Posted February 6, 2003 Report Posted February 6, 2003 Hi yall I see on this site that the 3100 is said to have 160 HP, some others I have seeen it saying its got 175 HP. Which is more true? Anyone ever dyno these? Also, I have my K&N, and should be putting a new exhaust on soon. This exhaust will be /-----(Dynomax Super Turbo) ---- (y tip) ------(cat)-------- \-----(Dynomax Super Turbo) ---- (y tip) What would the est. HP be after this? Just curious. I know the only real way to tell is dyno. Just wanted to know what this would be close too. Jon Quote
Robby1870 Posted February 6, 2003 Report Posted February 6, 2003 well, your 3100 has 160HP. The new ones they put in Grand Prix SE have 175HP. The re did them or something. Im not sure what the differences are, but I know they re did the motor in 97 or 98 and got 175HP. -Robby Quote
Brian P Posted February 6, 2003 Report Posted February 6, 2003 It was '99 they changed the intake manifolds to have bigger ports, the heads slightly different, maybe some computer enhancements, that's about it. Quote
