[QUOTE="Bad Company, post: 17023914, member: 141815"] To make Hp and have the engine survive you have to work on what restricts air into and exhaust out of the engine first. The reason you do this is to keep the intake air temperatures lower. If the air entering the cylinder is much cooler than normal then the chance to have detonation occur drops significantly. The idea that these engines are going to self-destruct on a specific fuel at a specific Hp output is ridiculous. They self-destruct when they encounter detonation no matter how high the Hp output. To me the only thing you have to manage is detonation. If you can do this then the engine shouldn't be limited in its Hp output. I also think that an aftermarket high quality ECU is the best way to monitor the engine and to be able to limit timing easily to stay away from detonation at all times. The Hp limit is not controlled by how much Hp the engine produces, but by what the conditions are at the moment in time that exist in the engine that causes detonation. Stay away from detonation and the Hp output can be much higher than what is considered normal for that engine. I'd be leery of 1200 Hp on pump 87 octane fuel to 93. The problem I would worry about the most while on any pump fuel you try to run the engine on is the quality and consistency of the fuel you purchase. Just because the pump is advertising the fuel as 93 doesn't guarantee the driver that was delivering the fuel to the gas station didn't inadvertently make a mistake and dump 87 in the 93 storage tank. Too many variables in the fuel you purchase at a local gas station. I'm seriously thinking of limiting both boost and RPM for anything lower than E40 in my car to lower the potential. Talking with Shawn I know he will be extremely conservative in timing of this engine. He also monitors intake air temperatures with the MoTec ECU to adjust timing tables in real time to limit the possibility of detonation while the car is being driven. [/QUOTE]
