Not my car but I installed a kit on a 03 auto coupe. at about 7 psi it put down 350 hp and close to the same tq. Been a while so not positive on the exact numbers. But the car has 54k and been SC'd for about 20K. Not a single hiccup
394whp/335tq with 3.12 pulley. Added 2.87 and getting tuned in a couple of weeks. Motor has 13000 miles with vortech and 18000 miles without. It's my DD.
so how much does it really change going from 3.33 to 3.12? anyone have numbers or graphs to show the difference here...and opinions of it would be great? thanks

yeah thats all i have to go by really...sucks not being able to compare in person by riding in each or something...any dyno graphs to show any differences will help...I just wanna know if its worth it cutting my vortech warranty down from 3 year to a 1 year...i know people have problems with these blowers so i would hate to kick myself in the *** if i change it then have problems 2 years from now and need to pay out of the pocket..but if its worth it its worth it..
dynos for each pulley span 30-50 hp it seems. You could run a 3.33 and have higher hp than another car with a 3.12 etc etc. lots of 3.12 guys pulling much higher #'s than guys with 2.87s.

I'm in the same position. I'd like to jump down to the 3.12 but don't want to void the 3-year warranty. Maybe wait 2 years and if all is running fine jump down. My car isn't daily driven so maybe it won't make a differance for me anyways.

ah if i didn't DD the car i would go with 2.87 already, but i do dd it and am about to get tuned and have decided to just do it and go with the 3.12 at the same time as the tune..might as well. Hopefully the vortech kit treats me good and doesn't give me problems..

You just changed my mind.....screw it, I'm going to go with the 3.12 after my first oil change
