I just wanted to give you guys a follow up of my experience with Ohio cranks. I remember a big thread somewhere about 'em.
My engine builder suggested using one and I had doubts because of what I had read on RJ. He was honest and told me the limits it had and rated at max 1500hp.
My motor (632) ended up a little over 1200hp (no nos, yet) and I 've been running it since December 08. I've run the snot out of this motor. Every race it turns 7,400+rpms no problems. Early January I blew a rear ring and pinion apart and hit the rev limiter at 8,400. Also recenty (the pass just before the picture you see as my avatar) had a shifter maulfunction and go into netural. Again pegged the rev limited at 8,400 and still going strong. I know it's no comparrison to a Callies, but just wanted the guys on a lower budget to know that the Ohio cranks have been doing well (so far) for us.
