Les, actually they are quite smooth, they use a counterweight on the eccentric shaft behind the flywheel to balance it out. Smoother power than any other car I have owned.

It moves in a circle, no transfer of up and down motion to circular motion, this makes for a very smooth engine.

Is it pride or a rabbid following that keeps the rotary in production. The same could be said for the rear engined 911 platform, obviously the Cayman posses a much better balanced platform with its mid engine layout and could easily replace the 911 as the super car that Porsche makes.

The same goes for the Rotary engine, I am not interested in the RX8 at all, I think the Renesis engine, while a remarkable piece of technology putting out 250HP with out a turbo is amazing, Its what happens to them when you boost them that disapoints me. The side seals let go.

So here I am stuck with my 20 year old RX7 making over 500 HP from 1.3 liters because everyone knows they have poor volumetric efficiency running circles around most every car I encounter on the track and at autocrosses.

I am now challenging other members of a local wesite to beat me in an Autocross, think of it as street racing but with turns and timing lights, I will pay anyone that beats me $100 but if they loose I get $50. I am going to make a lot of money with my poorly designed poor volumetric efficiency, Rotary car.

Hopefully Mazda will grow some balls and turn out a 20B powered RX7 in the future along the lines of the one Pettit Racing makes. They transplant a 3 rotor engine (20B) into a 3rd Generation RX7 and it makes 550HP easily. Many go into the 700HP range with them.

Consider my 2 rotor engine put 400 to the wheels and will soon put over 450 to the wheels and trust me there is plenty of torque. Enough to make my 10" wide Hoosier slicks gove up the fight as I rail through the RPMs in 2nd and 3rd Gear making me use my right foot an aweful lot to keep it straight.... god I love that car.

You may now continue with your Rotary bashing.
