Rb30 - Rpm Questions

[The Mafia]

Guys, is it relatively easy to make one of these blocks rev safely at 8000rpm?

I want to start building one and get it balanced and blueprinted.

Can people with this kind of block tell me about it?

Thanks

I dont believe any RB will consistently rev to 8k safely.

Bu5ter has gone the whole hog inc. aftermarket harmonic balancer.

From what I gather a nice build, keep everything light + a good balancer and its as close as you will get to safely.

EDIT: Oh ... and huge cams.

Cam it as if you had an rb25 reving to 9000rpm.

the rb30 thread tells all you need to know, but i think theres issues over 7000 with the harmonic balancer, at least i recall reading that

you probably wont need to rev out that much with the 3 litre bottom end anwyay

so I could still rev a balanced 3l bottom end to 7 like I do with the 25?

I just don't want to loose any RPM if I build one, as I love having 7000rpm to play with

my rev limit on the 3Lt is set to 7200

from a few guys who have found out the hard way, the RB30 crank reportedly has major harmonic issues at 7500rpm. MAJOR issues.

having said that, i'd just rev it straight through that pissy little harmonic, it'll be gone quicker than you think.
