We're you able to reuse the crank or did you have to replace it?
I have a factory pulley on my messed up crank now with pins in it holding it to the crank, the pulley itself can almost slip into the snout.

Depending on the blower it takes way more than 50 hp to spin it. SME did some testing a while back that shows 200+ hp to drive these things. I think the F2 was around 350 hp.

Pin it, it's a no brainer. If you know what your doing it takes like 10 minutes tops to pin it.

Maybe so, back when I had a bolton 01 lightning the talk on nloc.net was it took about 100 crank hp to spin the eatons hard enough to make like 11-14lbs. I wasnt sure if the centuri type took more or less hp to get similar results. Figured Id err on the safe side.

That's a great comparison. It reminds me of when people just getting into blowers want to buy an F-1R and stick it on a 4 bolt per cylinder LS engine, when an F-1A will normally (in most instances) push all the boost the engine can handle. They don't realize how much power is needed to turn an F-1R, and a lot of times they would make more power with an F-1A. Bob

pin it now. later when you build a motor you will have a forged crank with a key on it. wont have to worry bout it then.
