Rotaries are amazing!

I'd say almost 500hp is pretty good out of a 1.3L motor. Especially in race classes restricted by displacement right? it's hard to find a lighter engine with that much of a usable power band

The 1.3L is a bit of a misnomer actually when compared to a standard internal combustion engine. Each rotor face has a displacement of .65L per rotation x 2 rotors = 1.3L per rotation. Now take your .65, and multiple by 6 faces = 3.9L. so by the same way a piston engine is calculated the 13b would actually be a 3.9L engine.

Interesting... I need to do some more homework maybe. I do stand by my statement that light is good, and so that is one thing rotaries do have over their similar piston powered counterparts.

Lots of hostility in this thread though

I own both a Piston & a Rotary powered vehicle. Both have their cons & both have their pros.
