Another Pulley Question-(sorry)

[FearTheSnake]

I hate to beat this question to death but can someone explain all the different size pulleys available and approximately how many lbs. of boost to expect from each one?

Also, is there one available that offers a small gain w/o having to change Tunes/HE's or cause Belt Slip until I can shell out the bucks to compensate for a higher boost pulley?


Thanks in advance!

Typical boost gains over stock pulley (3.65")

1.5-2.5 lbs. 3.400"
3.5-4.5 lbs. 3.100"
5-6 lbs. 2.930"
6-7 lbs. 2.760"


The 3.4" pulley is the non-chip pulley. In otherwords you can get about a 2lb boost gain without having to retune the cars computer.

Hope this helps.:)
