does anyone know what size pulley the 500 efi side mount kit came with? im making about 4-5 lbs of boost and might be looking to up it a couple lbs once i get the bmax drives on.......thanks, ted

anyone?

ive got the same set up i will look this weekend

Cant you just measure the diamater of the pulley?

I think they were 3.125" I have a 10 rib one if you need it.

just measured mine 3 inches on blower 9 on bottom

Thanks guys, I guess what I really need to know is what pulleys do I need to run 7-8 lbs of boost and does anyone know where I can buy them or does anyone have a pair they wana sell

2.75"...I think is what I ran on my 454's. 8.75:1 pistons with those 2.75's gave me about 9.5lbs or something like that on box-stock Edelbrock aluminum marine heads (same as the 525efi's)

ok thanks jason......
