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??)
