So I blew my engine over the weekend

We know what kind of power simple things like exhaust make on even stock port rotaries so I stand by my prediction.

190BHP/210BTQ

So what kind of RWHP/RWTQ should we see at that level? 150/160?

You have to take intake charge temperature into account, too. The thermal efficiency of Roots blowers doesn't tend to be very good. But I'd be very interested in seeing the results if you do go this route.

Basically, if you're looking for monstrous power, look elsewhere. But the drivability and throttle response are outstanding. It feels more powerful than it probably is. And it makes such a lovely sound. Yes, I agree, turbos are "better", but supercharged rotaries certainly put a smile on your face. I'll be able to compare the two directly after I build my REPU's new engine.
