just responding to this statement made by you.

you gonna hit 500 hp on fuel at the fall brawl with your "benched pump" or do you need drugs to see that number?

Ok gas engines change timing due to rpm changes and so do some dieselsthe point of retarding the timing is to keep the egts down at the higher rpms its kind of a way to govern the fuel without the govonor kicking in. Ok in most case advancing the timing is done to keep egts down hence the reason why when we add more fuel we advance the timing. Well advancing the timing is like predicting that the fuel will be put in at this point and burned at this point by putting the fuel in early we cool the piston wich cools egts it still burns at the same moment but we put it in sooner at least that's the way it was explained to me. So when the pump retards the timing its preventing overburn of fuel so to speak
