I have driven a gsl-se rx7 for about 7 years and the way that I describe the 
power of a stock 13b is think of it as a 2 liter 6 cyl. Six combustion chambers 
making about the power of a 2 liter. Just my opinion.

Since the rotary lobe has three sides, isn't it more like 3 power 
pulses per revolution per rotor?? (I had a visible wankel model as a 
kid... trying to remember...)

And since a 4 cycle piston engine basically has one power pulse per 2 
revolutions the factor would be more like 6x...

Just thinking out loud... (is there a rotary specialist in the house??)
