That's exactly how crate engine controller will work with the pressure sensor in AC system and PWM fan control. Will modulate fan output only enough to control pressure. This is how Jackass, Red Devil, Mayhem and Camaro XV are set up.

I hate listening to a car and all you hear is the fan screaming.

Ok Charlie - next time we'll use small words and speak slowly (or buy you enough margarita's you won't care). I get this same abuse from my wife and kids - now you too?

I don't know what your talking about - there were tons of women in Rolla, just not many of them.
