Wilson Manifolds High Flow Throttle Bodies were developed using the latest computer modeling software and test equipment available to produce designs that yield the maximum flow per square inch of cross-sectional area. This results in maximum power for any given throttle body type and size. Four barrel style throttle bodies are designed to work with our line of billet spacers and incorporate a tapered and radiused throttle bore and precisely machined progressive linkage for smooth throttle operation. They also feature inward opening throttle blades to eliminate any part throttle directional influence by the blades that can cause poor air distribution. We have also redesigned our Dominator style throttle bodies to incorporate improved throttle linkage and to significantly reduce overall mass. All throttle bodies feature stainless throttle blades to control vibration and reduce thermal expansion Throttle blades are fastened to the throttle shaft using aircraft quality hardware that is both Loctited and peened to assure positive retention of the blades. Throttle shafts are machined to decrease their cross-sectional area, which increases the actual cross-section available for airflow. All throttle bodies are machined from billet 6061-T6 aluminum on precision CNC machining centers for consistent quality and light weight. High flow throttle bodies are available in 4500 and 4150 four-barrel styles as well as many single bore sizes in Ford style.

Racers spoke and we delivered! New for 2021, the 123mm “HB” will join Wilson Manifold’s Hi-Boost throttle body line up. Specifically developed for severe duty and high boost applications, the new design provides industry leading performance and durability. We start with a massive 5/8” (.625”) stainless steel shaft with unmatched sealing strength, Precision fit TPS engagement that is compatible with either Ford or Motec TPS sensor, accompanied by a more versatile two way adjustable linkage system. Also, introducing a unique tapered blade; designed to enhance air-flow and strength. The same 5” V-Band inlet and outlet makes the 123mm HB a direct replacement to our original 123mm throttle body.

HI-BOOST (HB series) of performance throttle bodies. Specifically developed for severe duty and high boost applications, the new design provides improved performance and durability. We start with a sealed shaft that is pressure tested to 100 psi and stable under the high engine temperatures and high inlet air temps seen in competition and high-power street applications. Next, we've redesigned the mounting coupler for the TPS sensor to eliminate erratic signals sometimes seen under high boost. Then the blade is installed in a split-shaft for superior strength – counter-sunk mounting screws hold the blade in a contoured design for improved airflow at full throttle.

Holley Carburettor (4160) 600cfm Alloy Body Vacuum Secondary Manual Choke

One of the most trusted carburettors of all times -the 1850! Its 600 CFM of airflow, vacuum secondaries, single fuel inlet and mechanical choke makes it amazingly universal. The 1850SA is constructed from aluminium which compared to its zinc counterpart equates to a weight savings of 40%! Being aluminium also means it will hold its shine and can be hand polished for a custom look! Don't trust your performance to just anyone, Holley is the only modular carburettor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.

• Vibratory polished aluminium for good looks, weight savings and long lasting shine
• Performance upgrade for stock to mildly modified vehicles
• Universal calibration for easy bolt-on performance
• Manual choke (cable actuated - hand controlled) for precise cold start control
• Vacuum secondaries for use on wide variety of vehicles. Compensate for all vehicle weights, gearing & transmissions to allow smooth opening of secondaries.
