3rd gen 3sge does anyone know the recommended octane? Or most likely RON since it's not a US engine? I've been bashing my brains in trying to figure out this problem and refuse to go to another race with it. After about 30 hard miles 5k RPM.... the engine starts cutting out lower and lower in the RPM range until I cant rev over 4k RPMS.
I've been running 87 octane, i'm thinking the knock sensor could be detecting something and slowly pulling timing. If this is the case i'm an idiot, and created a lot of headache for a stupid easy fix.... just sucks cause there's no easy way to test it.

Could the fuel pump be overheating? Not sure what fuel pump you are using but I could see where the pump might be wearing out if it's still the original pump. I'm a bit surprised that you don't have a wideband installed in the car, but I guess it makes sense. I certainly wouldn't take the time to look at it mid-rally.

I installed a new fuel pump before sno*drift, much quieter than my last one. I have external pumps since I have a fuel cell. -6 lines through the interior of the car. Personally i wouldnt waste my money on wide band unless it was turbo'd. -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq
