I have a used Weiand supercharger I'm looking to sell. It's a nice unit very low miles. It made 5 pounds of boost off the gauge in the car. Yes it has the teflon strips on the rotors. It's for a SBC it comes with what u see here plus a belt an lower pulleys. Look at how clean the rotors are!!!! The whole set up could use a good polish job. Other than that drop it on your engine an it's go time.... I'm just up grading set ups that's the only reason I'm selling. I want less than half of the price of a new one this size. If interested please contact me. Don't really wanna cause its heavy but I will at buys cost.... Thanks for your interest!!!!
