Ok.. So I have a Unorthodox main pulley on my current motor.. And the one I bought from Gotham is coming with a Pettit main pulley..

Does anyone know if there is a size difference? Performance difference?

I'll keep one and sell the other.. just don't know which one is which yet.. Any help appreciated.

i thought the unorthodox one had the splined sleeve built onto it or is that a different brand that does that? Mean you can **** up while swapping pulleys and allow the front cover bearings and thrust washer to drop out of position while installing it. The pettit is bolted to the splined sleeve.

You know... I think you're right. The Pettit pulley does only replace part of the stocker.. (same outcome I'd imagine).. price is like 250 for the unorthodox, and 219 for the pettit.. Hmmm..

Well, damn. I do like the unorthodox one.. It's super sleek; well made..

Oops.. They are almost the same price.

UR shows a 16HP gain after install..

Pettit claims 10HP gain after install..

you can make up the hp/weight ratio loss by boycotting mc donalds, burger king or wendy's for a week

i don't foresee a 10-16 hp gain from the pulley.... i had all underdrive pulleys on both FDs and really couldn't tell a difference.. i did it just to reduce WP caviation at higher RPMS.... I have a Pettit Main pully for sale if you are interested though...

Me either.. But they do show a dyno graph? Who knows.. I did so many mods I don't know if the turbo made more HP than the black interior LOL!

Don't need it.. I have one!!
