COMPETITION THROTTLE BODIES
UNIVERSAL 4-BARREL THROTTLE BODIES
These progressive 4-barrel throttle bodies bolt directly to standard square-bore or 4500 Series carb mount flanges for competition electronic fuel injection systems based on our Victor Series manifolds (see EFI Manifolds). Fully machined by Edelbrock, they are assembled/calibrated by Magneti Marelli USA and include a GM style throttle position sensor (TPS). #3878, #3879, and #3888 include a Delphi/GM idle air control (IAC) motor. #38783, #38793 and #38883 include a Hitachi Linear IAC motor and must be used with our ECU systems on the Pro-Tuner EFI Application Chart. Standard style air cleaners (5-1/8" or 4500 series) will fit. Available in standard finish or black powder-coated finish for a great look with performance to match.

*NOTE: It may be necessary to plenum match the carb flange of the intake manifold to eliminate a positive step created by the oversized bores of the #3888, 3988, 38883 & 39883 throttle bodies.
 
VICTOR LS SERIES RACING THROTTLE BODIES
VICTOR RACING THROTTLE BODIES & ADAPTERS
Based on our 80mm LS1 throttle body #3867, the Victor LS series 90mm racing throttle body is designed to increase flow and horsepower potential in competition applications. The lower water tube has been removed, but it retains the stock LS1 style TPS, IAC and PCV port. Extra idle control is provided with the addition of an idle bleed screw. It has both an LS1 and LS2 intake manifold flange and can be mounted on aftermarket LS1 manifolds with a 90mm opening, or LS2 and LS7 factory manifolds, but does not retain all stock equipment or throttle cable setup. It is perfect for enthusiasts who want to use an LS2 or LS7 manifold or entire engine in an older vehicle with no fly-by-wire throttle.

COMPETITION THROTTLE BODIES
VICTOR RACING THROTTLE BODIES & ADAPTERS
Based on our 5.0L Mustang throttle bodies, the Victor 70mm and 75mm race throttle bodies can be easily adapted to a wide variety of applications. We eliminated the idle air motor mount and all unnecessary vacuum tubes, making these throttle bodies especially well suited for boosted applications. The throttle arm has a cable wheel with multiple take-off points. They are cast and fully machined by Edelbrock, then assembled by Magneti Marelli USA and come complete and ready to run with a throttle position sensor installed and pre-set. These throttle bodies can be adapted to a number of applications using our 1/2" thick spacer/adapters. Intake port matching will be required.

UNIVERSAL THROTTLE BODIES
PRO-FLO XT THROTTLE BODIES
These throttle bodies have provisions for either LS1 or LS2 mounting bolt patterns. They use a LS1 style TPS and 4-wire stepper motor IAC. They have been designed with the addition of an idle bleed screw to offer better idle control than other 90mm throttle bodies on the market. The bleed screw can be used to create a base amount of idle air flow instead of throttle tip-in, leaving the TPS signal unaffected. Ideal for use with Edelbrock Pro-Flo XT intake manifolds #7135, #71353, #7137, #71373, #7139, #71393, #7144 and #71443.

SMALL BLOCK FORD
This throttle body was developed for use with our Throttle Body Intake Elbows or with our new small-block Ford Pro-Flo XT intake manifolds #7128 and #71283. Includes a Ford style TPS and provisions for a Ford style IAC motor, OEM or Edelbrock #36017. Uses a standard Ford 5.0L mounting bolt pattern.
