Buyt Hector is right, too. our superchargers superheat the air anyway. It'* not really going to do us that much good. There'* a couple ways to beat that, though.
Yes they do. They add heat to whatever the temperature of the air is to begin with.
So if the incoming charge is 130 F and the supercharger adds another 140 F = 270 F.
And if the incoming charge is 50 F and the supercharger adds the same 140 F = 190 F.
There is still a net gain.
Of Course adding an intercooler between the supercharger and the engine will cool the charge back down again.
Below is a quote from Thrasher:
Thermocouple testing has shown aftermarket intercoolers to reduce charged air temps up to 130 degrees F (from 270 down to 140)! This results in a dyno tested 40HP, with considerably less possibility for engine-destructing detonation, thereby allowing even more boost!
Will - That 130 degree drop equates to a 13% increase in power. Their claim is 40 Hp
