As Jody pointed out....cooler charge means more power per/lb of boost.

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.
