    Weiand's Pro-Street Superchargers represent a significant leap in technology for obtaining substantial performance gains while maintaining drive ability and reliability. The 177 Supercharger is very similar to the 6-71 series in style but the 177 is a compact version, allowing you to fit this supercharger under most medium sized cowl induction hoods on trucks and muscle cars. The 177 Series superchargers are engineered to produce 25-40% more power while maintaining excellent drivability!

    All Weiand superchargers feature 100% NEW CNC machined parts (no remanufactured components). New thick-wall cases and rotors eliminate high-RPM flex and provide maximum reliability. All superchargers are 100% Boost Tested to help you squeeze the maximum power and efficiency out of your supercharger!

    Features & Benefits
  • Gain 100-175+ Horsepower (depending on application)
  • Substantial increase in torque, great for heavy vehicles and towing applications
  • Instant power every time you hit the gas! No Lag!
  • For Small Block applications, the drive ratio with the included pulley set is 1.71:1
  • For Big Block applications, the drive ratio with the included pulley set is 1.95:1

    Installation Notes:
  • Superchargers are perfectly suited for stock/modified engines with 7.5:1 to 9:1 compression ratios.
  • Designed for stamped steel v-belt accessories. Use of billet pulleys may require custom machine work and/or spacers.
  • Superchargers mount to manifold using 6 bolts along perimeter of blower.

    Kits Include: Manifold, Blower Assembly, Drive Snout, Pulleys, Belt and Hardware.
