SD is very low profile & reportedly has good low end for a single plane & it's a spreadbore. rpm performer is very tall & reportedly good top end for a dual plane & it's a square bore. I have a SD but no actual exp w it yet

I have both to try out! From what I recall from a previous magazine article............ the Perf. RPM had more torque in the low-end as would be likely......but not much.

I've used both on 440's before, the same engine even. The RPM is much better but does cause clearance issues. SD isn't bad at all, but I would go w/ the RPM if possible.
I want my fair share
