04 gtp pulley questions?

[Jtg1551]

I recently bought a 2004 grand prix GTP completly stock, and i was wondering what the smallest pulley i can switch to without having to do other mods???

Your car already knocks.

Don't touch the pulley unless you do headers.

Option 1:

You would be better going to a larger pulley.

Stock will knock.


Option 2:

How long do you want it to last?

 

[Jtg1551]

i know people who run a 3.4 with just a cold air intake, who never have had the knock. but i deffiantly want my car to last

 

[mechguy]

Well to be honest if you have a way to measure knock then just let her rip.

 

[Jtg1551]

i mean yes it still knocks there all going to stock, but he drove it for years and never had a problem, but just looking to be pointed in the right direction

Those people are pennywise and poundfoolish.

If you want your car to last, do the appropriate mods.
04+ take more modding to drop pulleys.

This is your starting point.

thanks i'll take some time and read this, just a random question, how often should you change your supercharger oil?

 

[Tuner-Extraordinaire]

id say every 60k.

 

[Jtg1551]

i just bought the car with 100k and have no clue when it was last changed, so i just bought some.

Good call.

Take care of your car and it'll take care of you.
