Rotary engine gear cuts question
Posted: Wed Feb 04, 2026 1:11 pm
Anyone here have some experience tuning rotary engines. I am tuning a 2 Rotor for Time Attacks. This one will be on straight ethanol/methanol mix and 35psi boost and would like some opinions regarding the settings on flat shifting. On piston engine i did a lot of tuning but rotaries are more sensitive when it comes to cutting fuel, ignition and retarding.
I have already experimented using retard and ignition cuts but shifting is still hard on big loads. I am hesitant on adding fuel cuts too as the fuel itself is the internal lubricant of the engine or i am being to cautious as cutting the fuel for so short of time (100ms) will not harm the engine?
Thanks guys.
