G'day guys just wondering if any knows what's roughly the max hp u can put through a standard Nissan rb30 crank?

RIPS has a car that has 1400hp using a standard rb30 crank,

I don't think there is a Max power limit on the standard crank, the block an cylinder head will split before you have any problems with the crank. The only problem people have an that's with all rb's is the oil control issues, if you run out of oil you will spin a bearing an chew the crank.

Thnx for ya help :-)

there forged std . u wont break it

Don't know about them being forged, but they are nitrided from factory which is a hardening process. That's why if rebuilding an RB engine you only want to have it linished which will polish it up nice for the new bearings, if the journals won't clean up without having to go the next under size bearing you have to have it nitrided again, going under size bearings ain't a good idea any way as it reduces the over all serface area of the journal.
