so i found my answer:
The Cobalt SS Supercharged Coupe features a Ecotec 2.0-liter supercharged four-cylinder engine and five-speed manual transmission. The engine includes an Eaton M62 helical roots-type supercharger and features an air-to-water intercooler to reduce the temperature of air entering the engine. The supercharger produces a maximum boost pressure of 12 pounds per square inch (psi).
So you guys have the same type of charger as i do. only difference is, i will run 7-8 psi to get to 300 and you guys are pumping 12 to make 225-230. thats why your inlet temps are high. i'll be cooling the temps with 520cc injectors.
