N2O and rev limiter?

[Blown14psi]

Does anyone know what happens when the engine, on an apex, hits the rev limiter? Does it cut fuel, spark, or both? I'm curious because I'm using a wet N2O kit and if it cuts just spark or both fuel and spark that should be no problem. If it cuts fuel and not spark then we have a big problem LEAN OUT and possible engine burn down if the engine bumps the limiter for an extended period of time.

I always believed it was spark that was cut out by a rev limiter.. Anyone ??

Cuts the spark, and will give you a slight pop sound on the bottle. Hit this many times and still no problems, but you don't want this to hit all the time. I usually hit the rev limiter when I have loose snow conditions.

at what rpm does it cut out and is it the same on an rx?

There is a number(11200?), but it seems people have revved the motor higher on the tach.....

11,200 rpm is the rev limiter on a stock machine with stock ECU/CDI. Same on RX-1.

Thanks Guys

Yamaha did it right then. I have a supercharged mustang, and when it hits the limiter it cuts fuel but not the spark so it leans out big time if U spray with a wet kit.
