Man, ATI takes their time!

I ordered my damper in mid october and was told today that I should have it by about the 1st week of February. Originally I was told 6-8 weeks. Man, that's about 14 weeks!

Yeah, I had the same experienceon the last three crank pulleys I ordered. Good product quality, lousy customer service...go figure!!

yeah, but this is a custom damper not an off the shelf. Mine's currently being plated and should be done in about 2 weeks.

sure is. I wish they'd get a move on. The car is depressing to drive without boost. Once you have it, you can't go back!

BTW, my prediction with the 27 tooth cog drive- 15 psi+ of boost. I was seeing 10psi with a 2.75" pulley previously.

What's the tooth ratio on your setup?
Crank:blower

Nevermind, saw it in your other post

OK
ran these #'s, figuring about ~100hp to run the blower

torque = (HP*5252)/RPM

100hp
7,000 engine rpm
75 ft*lb @ crank

74 tooth/27tooth

~20,000 rpm @ blower

~26 ft*lbs @ blower

So that's tells us roughly the sized sprag we need.
