I have not seen anyone do a thread on Crank Pulley's and nothing like we have for the Cat Backs, so here is my attempt. In alpha order (I will edit as people tell me what they want to see)

This is a nice complete list. When I started investigating crank pulleys it seems like everyone recommends the ATI.

 

Wow, I didn't know there were so many! Yeah, I'd definitely like to hear what people think is the best.

 

Clint from Defenders of Speed and Jan from RVM normally recommend the PRW SFI FluidGel one if you hit the track.

 

I like the Alta and Craven never had an issue with either and see no reason to spend more money than I have to actual fix a stock issue.

 

perrin = alta btw , and that pulley you showed is not for our cars.

And that eary R53 crank pulley that is destroyed is from my car
(Way's jaw about hit the floor ( )when he first saw the damage! haha)

 

Yeah I know Perrin is Alta, but Horsepower Freaks offers a Perrin specific for the MINI Cooper, now if they ship an Alta, then it would be different than what they have pictured, which would not be the first time someone has the wrong thing for us!

Think I should add in the blurb from each Manufacturer with their website link?
and a few Vendors at the very bottom that sell each?

 

no worries. The photo posted is just the image HPF pulled for all of the perrin performance pulleys. the one pictured in particular is for a subaru EJ series motor

Ours has no need, nor clearance, for two accessory belts as the one in the picture has

 

I just installed the alta 2% reduction crank pulley since my stock one flew apart... but somehow my belt still stayed on the slick metal underneath... I was able to drive it home. Anyway, so far so good. I can feel a bit more pep with the ac on. But that is just my butt dyno. Went in super easy too.

Im enjoying my new found power.

 

Do I get bonus points for my pulley just by showing up in this thread?
