The Ultimate Rotary Engine

Last updated: December 21, 2003

OK, so this may not be THE ultimate engine, as there are a few things that could be done differently. Or different vendors besides Pineapple Racing. Or for other generations besides the FD. Or to use a 3-rotor as a starting point. But the point here was to do an exercise in what-if money were no object? What would it take to build a no-holds-barred rotary engine? Check it out:
