I am just going to throw this out there, but what about Rally X red :-
it is a proven fact that red adds BHP to any engine

this one being my last engine build a full custom 1380cc A series with T3 turbo charger pushing 20psi boost and producing 225 bhp at the crank.... kinda makes ya wonder what they did wrong with the large CC V8's we have in our carriers
Hope i have tickled some of you
