Pro drag racers ARE all over this!
NASCAR has found gains all over the place;
1) Down sizing oil pump to flow just enough oil and no more, gains 8-10 HP
2) Running a vaccum on the crankcase to suck out air below the piston before the down stroke, gains 10-12HP
BAT lists the electric water pump as gaining 6HP on the Duratec.

Little things can make a big difference.



also keep in mind that doing something small my give little gains but in conjunction with other mods that small gain will become greater just like adding just and intake yeah you gain some power but add exaust to that and your gains are gonna be more than if you just looked at the exaust with a stock intake
