A few years ago we tested intake air temps on a well built 355" SBC running 18lbs of boost. We started our testing w/ 240* intake air temps and made 720hp. We made controlled pulls on the dyno and lowered the intake air temp to a respectable 140*. Our next pull was really lean indicating there was more air density. Once we added the fuel, we noted 807hp.
With our new intake air temps, the engine now responded to added timing. Our first 2* netted 20hp across the board. Our next 2* netted an additional 20hp across the board totaling 847hp. That's a 20% increase in power! We stopped there as the combination was out of fuel pump and injector.

In your last sentance, That would not have happened if you were using Methanol Injection! 1). Methanol Injection would pick up where your fuel system falls short seeing it's a fuel and another injector! with this said that also means it lowers your injector duty cycle quite a bit and you don't have to wory about intercooler heat soak.. Plus you loose the weight of the intercooler and don't spend a fortune on race gas...
ALOT of possitives to Methanol Injection..
