    If you are looking for a supercharger to fit under the hood of your hot rod, then Weiand's 142/144 series superchargers are exactly what your looking for! These Pro-Street supercharger kits are designed and engineered to give small block Chevy's 25-40% more power while maintaining outstanding street-ability!

    144 Series Weiand Superchargers feature a low-profile design that offers even more hood clearance than the 142 series. The 144 series is great for tight engine compartments and they are a practical addition to any performance or tow vehicle where hood clearance and/or the use of a long water pump and three v-belts are required. PTFE tipped rotors in the 144 superchargers create tight rotor to case tolerances for improved boost capabilities.

    Both the 142 and 144 series 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
  • 400-450 Horsepower from a mild 350 Chevy.
  • Low-Profile Design (may require cowl induction hood in some applications).
  • Improved torque for heavy cars and towing applications.
  • Great power adder for low compression crate motors.
  • Full-Time Power every time you hit the gas with no lag!

    Installation Notes:
  • Superchargers are perfectly suited for stock/modified engines with 7.5:1 to 9:1 compression ratios.
  • Superchargers mount to manifold using 4 bolts through the bearing plates.

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