Crank pulley for Eaton blower, anyone?
 

Anyone stumbled upon an easy solution here? I'm looking forward to getting some bracketry/other layout figured out, and if there was a easy off the shelf pulley setup/solution I could start with, I know how far out I need the blower to be.

Thinking I want about a 3.63" diameter crank pulley, but not set on that yet. It seems awfully small, but on paper would drive it about as fast as I think I want to drive it. This figuring 12krpm blower redline at 9krpm engine redline, stock ford blower pulley size of 3.15" diameter. Haven't verified the 3.15" figure and I know many drive them past 12K, but this is just a starting point.

Unless I won the lotto and could buy one of embree machine's reman (heck, re-engineered) eatons that support crazy RPM and ~500hp. :)

I know I should probably hit up Sterling and Peejay directly as I bet both of you have input here!

JR still hasn't sent me pics of what he had done up when his was "on" his car.

Thanks in advance!

hey crack smoker
wacth your mouth. if you want to find a pulley that size and promade. go hit the super coupe forum. there is a guy on there that sells them. but his are 3.65 but they should work do the math and sun it to just a hair over seven. What are you gonna run this one? The smoke machine? By the way i ahd fun at the auto cross you should have come out. I had pics of my eaton there but you were not there. i should get them transferred over this week but i ahve to get time i spent the weekend purring new bushings in my car to find an se suspension today at the meet. well if you need any other info drop me an email i ahev the link at work for the guyys page he has a bunch of toys for those eatons.

Does that super coupe pulley go right on a 12A or 13B eccentric shaft?
