Description

For full tuning capability and street friendly with a universal fit throttle arm vacuum fittings and provisions For a TPS sensorEdelbrock VRS-4150 Race Performance Carburetor #1308 850 CFM is street friendly but race ready. The one-piececast aluminum body fits all 4150 and 4500 carb flange manifolds without requiring an adapter plate. A street throttle armMoly-coated throttle shafts and built-in provisions for a standard GM three-wire TPS mount add features to this carburetor that are ideal for any user. Multiple vacuum hook-ups keep this carburetor usable on the street but still ready for the track with larger capacity fuel bowls and four circuit billet metering blocks with screw-in emulsion bleeds. All of these features make for easy tuning and great versatility in many applications. The 20% larger capacity fuel bowls feature internal ribs to control fuel sloshand a sculpted baffle directs incoming fuel to the sides to minimize bubbles. The floats have corner cuts to avoid shutting off the fuel flow during hard corneringand jet extender notches and jet extenders in the rear to keep the jets covered in fuel under hard acceleration. VRS carburetors allow users to externally adjust idle bypass air as the adjustment screws are accessible without removing the air cleaner/scoop. The advanced idle circuit features interchangeable idle discharge jets in all four corners to allow for a smoothclean idle with the use of biglow-vacuum camshafts. Normally found only in high end racing carbsthe VRS includes fully adjustable intermediate fuel circuitswhich help to provide incredible throttle response. Finallyfor greater control at high RPMthe high speed/main fuel circuit is split into two bleed circuits â?? one each for the lower and upper sections. As an additional featurethe power valves are located on both primaries and secondaries that support optimized jetting. The power valve will add fuel as necessary while the power valve protection circuit prevents diaphragm damage from backfires.
