Rotary Engines
#11
I have an Atkins built rotary in my autocross RX7. Three years and 32k miles running consistantly at 9500 RPM, no problems ever, runs like a champ. Atkins can build a rotary that is reliable and turns over some serious power. Hope this helps....Donnie

I recently built a ceramic seal motor which is capable of 800/900 hp and it's a two rotor 13b not a three rotor like the boat.

615 ft/lbs is out of 120 cubic inches.
