Can you use any pulley for the supercharger? Like a 3" steel idler pulley from the auto parts store? This might be a stupid question but I am a cheap ass.

NO!!!!!!!

Do not use any type of "finger" puller. Only use pullers specially designed for pulling the S/C pulley. The stock pulley is so soft that you will bend the snot out of it and may end up damaging the shaft in the process.

Herc, I think he said pulleY no pulleR.


And to answer your question, no you can't. You can only use specially designed supercharger pullies, along with speically designed pullers.

Besides, you probably don't have the supporting mods to RUN a 3" pulley, given the question being asked.

dont even think of doing a pulley swap......but if you do run a smaller pulley with no supporting mods you might as well run a 2.6"

Heh. I want to see someone try and press a 2.6" on an unaltered snout. That would make for some interesting drama, as long as it wasn't my car.

i wonder what would give first... the puller, pulley, or fins on the snout..

probably the pulley

My money goes on the little threaded portion of the puller that goes into the snout breaking.

Thanks for the help guys but I am not a moron. I mentioned the 3" pulley at random, I know plenty about engines

From the 97-03 FAQ:

Supporting mods for a 3.4" pulley:

CAI/FWI
U-bend delete
3" D/P
PCM
180* T-stat (drilled prefered)
1 heat range cooler plugs (copper core prefered)
A scanner is highly recommended in order to monitor the KR that will be introduced with the smaller pulley.
Hope that helps!

Lesson on grammar? WTF does that have to do with the search tool on the site? p.s. I was a diesel mechanic in the Coast Guard and currently carry a 4.0 GPA at Texas State university. So you might want to think about what you know about someone before opening your mouth. Furthermore, it was a stupid question but asked with a bit of humor and I was almost certain of the answer. However, if a blower goes out on a diesel at sea it is common to use anything available. So as a lesson for you I won't say anything about you because I don't know you. But I have a good idea of your age and type.

.........what the piss just happened?

This coming from someone who uses a k instead of a c to spell words? Hypocrisy runs rampant!

bobcatgtp10, don't worry about it. It's better to ask and find out then to waste money not knowing.

Thanks Rook and everybody for all the info.

guys guys dont flex your muscles over the internet,its not gonna help anything...insted you should be helping each other with one common goal, makeing the GP's bigger faster stronger.
