    Chevy Small Block Carbureted Supercharger Kits

    Fits: Carbureted Small-Block Chevy

    Vortech's blow-through carburetor systems increase horsepower from 30% to more than 75% depending on boost level and volumetric efficiency. The kit comes with a 3.33'' pulley system that generates 8-10psi @ 5500 on a mild 350c.i.d. This System is designed to be used with a long-style water pump and OEM V-belt drives or GM Performance Parts serpentine accessory drive system (809-12497697, 809-12497698 or 809-12497869). Vortech recommends compression ratios between 8:1 to 9.5:1 with 9:1 being ideal.

    This kit includes a cast aluminum carburetor enclosure assembly for use with Holley #4150 or Demon 750 MD carburetor. The enclosure pressurizes the float bowls and throttle shafts for seamless response. It features front and rear -8 AN 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. For Holley or Quick Fuel carburetors use fuel fitting kit 933-8M110-020. For Demon carburetors use 933-8M110-030.


    Features:

  • V-1 T-Trim supercharger
  • Vortech gear driven supercharger for unmatched reliability.
  • Supplied Belt/Pulley ratio will produce approximately 8-10 psi at 5500 rpm on a mildly modified 350 cubic inch motor (S-Trim systems)
  • Oil feed and oil drain assemblies deliver the best possible lubrication and cooling for the supercharger, even under sustained boost conditions.
  • Cast aluminum mounting bracketry with all necessary hardware.
  • 3/8" thick nickel plated steel for rigid supercharger attachment.
  • Inlet and discharge duct connection utilize-heat resistant silicon sleeves and premium quality stainless steel clamps. 10-rib, 6061-T6 billet aluminum supercharger crank pulley with hard anodize finish (6" diameter) and pulley spacer.

    Each Vortech Supercharging System is developed to operate as a seamless addition to the base vehicle. By employing the same methods as original manufacturers, Vortech engineers create integrated supercharger systems that appear as if they're original equipment yet operate at an even higher level of sophistication. The boost curve generated by Vortech Superchargers is ideally matched with today's highly evolved engines and provides a power-when-you-need-it sensation. The supercharger and its subsystems fully integrate into the vehicle's existing platform, yielding a smooth continuity of power and performance.

    Tuner Kits
    These configurations are designed for those qualified tuners or race shops who do not require the fuel managements items included in Vortech's standard systems.
