this super charger has been pulled off my commie because we are going the turbo route so this is up for sale excelent conditoion has a clucth which means you can switch the supercharger on and off via a switch (microswitch included)everything you need to put this straight on to your commie including used belt,and pully this puts out 5 psi which, can be changed to higher boost if you like the engine on a commie can handle 16psi believe it or not. thats what im doing 5 psi is still alot of extra power for these beasts turn your car in to a tyre shredding machine if thats what you want. i paid 2000 for this a year ago will also fit other applications
