So much success that IMSA and SCCA started issuing 300 and 400 lb weight penalties, doubling the rated displacement of rotary engines, and banned porting the intake ports(the equivalent to higher cams). The RX-2 and RX-3 had a pretty fair amount of success

What else built in 1972 can keep up?

Prices on these can actually get kind of crazy. In 2009 I used to get people that would follow me home in Puyallup when I’d drive mine. Biggest spur of the moment cash offer I ever got was $6,000. And it needed a fair amount of body work. I saw a mint one go for about $18,000 about 2 or 3 years ago.

There are only 4 moving parts in a 3 rotor engine. It’s not rocket science.

That poor Ranger didn’t deserve that.

Wankel engines weren’t designed for puttering around town, hence the misinformation about fuel efficiency. At speed is where Felix Wankel’s little engine GETS IT. In stock form, a naturally aspirated 12A or 13B will give you upwards of 40 miles/gal. between 70-80 miles/hour. And I say that as I recently did that in an…
