P.s. Id be surprised to see 200hp being transferred into them. I dynoed my zx12 @191hp and 101tq. I usually go through a set of axles a year due to twisting from the tq. I don't think the 1k motors could ever come close to the TQ#'s of the 12 and I'm sure that it's not so much the hp but more the tq that will hurt the 10bolt
