Hello All
Just joined today! Here is my question I have a 2004 GTP Comp G and I just changed the pulley to a 3.4. I have 17,000 miles on the car.
Do any of you have experience with Supercharger failure resulting from a smaller pulley? Are their other issues or concerns I should be aware of because of the modification. The vehicle is still under warrenty. I know the pulley will void the warrenty for the supercharger.

Welcome!


If that's your ONLY mod, I would either take it off or start a decent sized savings account earmarked for engine repair :-(

First & best bit o' advice: get a scanner! You will be amazed and appalled at the KR an unsupported 3.4 will produce, especially in colder weather.

Here's a good source for what you should & shouldn't do:

Thanks for the response Cliff, I should have added more information. I have also installed a K&N cold air charger or intake along with a Borla
cat back exhaust system. I will look into a scanner. Please feel free to add further thoughts.

OK that's a little better smile .

Although you probably should at least have a 3" downpipe and 1.8 or 1.9 rockers to run the 3.4.

Definitely get the scanner, or better yet a Powrtuner, which allows you to make adjustments to your PCM to maximize the benefits of your mods laugh .
