ChrisV, mate u got it wrong. At 3000revs a single rotor would fire 9000 times. Remember that they have three faces to turn per rev. I have an Rx4, with an early modle RX7 engine. It make 495.6 hp @ 16psi. with no boost in makes just over 350hp. Just like mafs said, thats a yell of a lot of hp/l. I'd like to see a piston engine do that from 1.3L. I closest thing that comes to my mind in comparison is F1 cars. 3L and about 800hp, with no boost. I make 269hp/L, Ferrari makes 266hp/L. Imagine if Ferrari started to develope rotary engines for there f1 cars. I'd say about over 1000hp. Rotary's will never be common place. That is why they are so great. Boys in their Holdens and Fords and Vettes just don't and never will understand them.
