I haven't seen a thread started on RB engines so I figured I'd start one.

I have a question about the RB V12 5 port engines. Anyone use it? How do you like the power? How's the power compared to a Mugen X12. I only race at the club level, and I'm looking for an engine that'll keep up with my Mugen X12 at Sun Valley's long straightaway, and thru the corners of course.
