Supercharger pulley

[whoender]

Where is the cheapest place to get a 3.5in pulley for my GTP? Cheapest I've found is $80.

Or you can look in our for sale section.

Thanks

The pulley itself is the cheap part, it's the MPS hub that adds to the cost.

Make sure you other mods before you just slap a pulley on.

I am u bend and resonator delete and colder plugs

[dsmuts]

That's probably not enough. How much KR do you have now?

[whoender]

Approximately 10

[dsmuts]

You have 10* of kr?

[Scottydoggs]

if you have 10 degrees of knock you dont get a smaller pulley.

[ericspecullaas]

death is knocking on that engine at 10˚ of kr....

[whoender]

How to i solve the problem

[Scottydoggs]

whats done to it so far? all stock?

[whoender]

Yes

[Scottydoggs]

i bet your motor mount and trans mount are shot to hell causing a few degrees extra, i was seeing 8.5 stock till i did u bend delete. that made it drop 2 degrees or so. headers would also lower the KR.

[whoender]
