I got my coupe back after installing the 3.12 pulley
Well, the broken cog belt for the Vortech pulley finally came in yesterday, so I was finally able to get it to Jeremy (at PerformanceFactory.com) to get the car running again. I had him install the 3.12 pulley in place of the standard 3.33 pulley for a couple more pounds of boost. He also retuned the UTEC so it is buttery smooth. Jeremy got a reading of 382 whp. All I can say is this is FUN!!! It really comes alive around 4000 rpm. I need to start saving for another set of rear tires because I have a feeling these aren't going to keep tread long.
Attached is a printout of all 3 max dyno runs. The bottom line is my original base line that was done on the dyno day of January 7, 2007. I got a best of 235 whp.
The middle line is with the Vortech 3.33 pulley for 347.98.
The top line is with the 3.12 pulley for 382.13 whp. I like the 3.12 pulley because the power curve moves farther down in the RPM range.
For you guys that do a Vortech kit (Jeremy has great pricing right now) just start off with the 3.12 pulley. You won't be disappointed. And if you get a used kit, start with all new belts.

the smile on his face when he got back from the test drive is all i needed to see!!!
the car is very smooth and very fast!! we might try a new exhaust here soon and see what it will do. should be interesting...
with a vortech you really have to get up in the revs, but once you are past 4000 well...
