GM Supercharger Kits
Notes: This Vortech blow-through carbureted supercharger system will provide an increase in horsepower ranging from 30% to more than 75% depending on boost level and volumetric efficiency. Systems include a cast aluminum carburetor enclosure assembly for use with Holley 4150-type, Quick-Fuel Q-QFT-850-BAN or Demon 825 MD carburetors. The enclosure pressurizes the float bowls and throttle shafts for seamless response. It features front and rear -8AN fuel inlet ports as well as multiple locations for pressure/vacuum connections. Linkage arms, splined shaft , and left/right hand spherical rod ends are included for simple throttle connection and adjustment. Carburetor studs are also supplied. Kits are designed for ''long-type'' water pump configurations. Short-type water pump applications will have to use a custom accessory drive crank pulley and spacer that is not available from Vortech. Low-rise intake manifolds are recommended due to hood clearance. Compression ratios between 8:1 - 9.5:1 are suggested with 9:1 being ideal. Includes 3.33'' diameter 10-Rib pulley
Streetable Horsepower! Vortech supercharging systems are 100% complete, right down to the wire ties. Each kit is designed, tested, and sold to be installed on vehicles in their original or otherwise stock form. Superchargers are engineered to deliver maximum performance and long term engine durability at safe boost levels on stock engines. Kits are the best-bang-for-the-buck when bolting on horsepower.
