When I can thrash the power the motor makes now I'll put some 1600cc injectors in there and wind her up some more and see how it goes, its got to pop sooner or later but at this stage its putting out good numbers and loving it.

We don't want it to go pop
Well I know some probably do, to prove themselves right about over-priced OS Giken RB30's vs RIPS RB30's, and to show that you are talking rubbish about standard cranks being good enough for the job.
So far, that's exactly what has been proved, the standard crank is able to run at the same level that the OS Giken runs at. OS Giken reckon they are strong enough for 1400bhp or 1500bhp, I forget which, but nobody here running one has 1400bhp or 1500bhp anyway.
So your standard crank seems to be able to handle the power that you have no problem at all, and I'm guessing the OS Giken boys here are running at the same level of power, their wallets will be considerably lighter of course. I don't see how paying a hell of a lot more cash for an OS Giken is really worthwhile, at the levels they are being run at. The RIPS RB30 seems to match it no problem at all, and that's without a fancy crank.
So why bother?
I'd take a RIPS motor anyday, the cash saved could be spent on big brakes and decent suspension, and other handling improvements.
ps: I suppose when it does go bang, you'll have a nice reference point of where to stop trying to increase the power. I still think it's a shame to kill that motor though, it has served you well.
