Run Pre-mix or run RA OMP?

So you're aware that not premixing or removing the OMP will shorten the lifespan of the engine, yet you're willing to do it?

I don't remember the exact hours, but Mazda did test running the engine without any sort of premix about 10-20 years ago, it was in either SAE papers or the book about Rx-8. I have to look it up

reason why Premix does not burn off as fast is because it's staying on the wall, which is much cooler and that's the reason why it will stay for a while. As for how many revolutions? if the engine can last hundreds of hours without any sort of premix, I think it will be fine for a while. Will it cause extra wear? a bit. but Rotary Engine have other problems that might kill it before this "Extra wear" happens.

off the top of my head, when Mazda first test Rotary Engines, their sample actually last about 200 hours before it failed from chatter marks, and that's lmore than 40 years ago.

Actually the best of both worlds would be an OMP adapter and premix in the tank.

if I can get rid of OMP without modifying the ECU in my FC and FE, I would. you can be on the safe side, but I would take it out without a 2nd thought.
