Well from the get go I haven't had much luck with my cobalt....First off the supercharger quit boosting so it had to be replaced. Now the supercharger dosen't "Whine" It whistles almost like a turbo, and at low speed with heavy throttle and max boost its hisses then goes up to a high pitch wistle. Boost and vaccumm, patterns are normals but the proverbial "Whine" isn't there. Could this be the charger cuppler or a bad exhaust leak. It also sounds like a constant farty hiss inside of the car when you step on it... Any suggestions would help..

Engine is stock....i dont want to mod over problems an blow it up lol.....

Thanks

 

gasket leak

 

can i fix it in the driveway or do i have to take it in...AGAIN.....

and which gasket?



thx

 

If it's under warranty there's no reason you should have to fix it yourself. Definately take it in.
