Supercharger Intercooling

[Paladin]

I am running a 302 with a vortech supercharger at 11 psi boost and I notice a dramatic loss of power on hot days (25+) especially after driving for a while and the motor is above 180 degrees. I am thinking about getting the vortech powercooler (air to water) to drop inlet temps, which should allow for slightly more boost (13psi) and timing. Just wondering if anyone has experience with adding an intercooler vs. non. It seems to not be an option on turbo cars. they all have intercoolers. Any suggestions /experience would be helpful as i checked the major mustang magazines and the old articles on the powercooler testing were not very informative
