I currently have a gm stage three pulley but can get the zzp 2.9. is it worth my time to change it or just leave it alone? Can't see there being a huge diff. Just thought i'd ask the pro's.!

 

smoothflowpulleys.com ..... ftw

 

^ What he said ^

 

okay but i have a zzp in my hand and a gm stage three on the car what do i use

 

They are different sizes, 2.9" is smaller = more boost (more heat)

 

stage 3 gm is 2.99", basically 3.0"
the others are 2.90". almost a 1psi increase.

watch your injector pulsewidths and afr. 2.90 starts to overwork the 42# injectors pretty bad in most cases.

 

does the zzp pulley have the 4 bolts to match up to the gm stage 2 hub???? if the zzp doesnt have the 4 bolts it wont work. Trust me just go buy the 2.9" from smoothflowpulleys.com......there the best i have had 3 of his pulleys, all have been fantastic

 

i have a nate 2.9 pully for stage 2 hub for sale for 40 shipped if any one is looking
