Stock 12a rotary puts ~90hp to the ground.
SRX7 12a rotary puts ~105hp to the ground.
ITA 12a rotary puts ~125hp to the ground.

I do not know what a stock 13b puts out, but most SpeedSource cars put ~180hp to the ground.

The rotary can be tuned for more peak power, but sacrifice a LOT of power below 5500rpm. The figures I posted are what people actually use (The highest SRX7 hp I've seen is 107rwhp, but it had nothing below 6000rpm).

I only posted this since Kirk's multipliers were mentioned.
