Edelbrock VRS-4150 Race & Performance Carburetor 950 CFM

Edelbrock VRS-4150 Race & Performance Carburetor #1309-E85 has features that benefit racers and high-performance street enthusiasts running E-85 fuel.

• Custom metering blocks and extra-large fuel jets specifically built for E-85 applications • Annular boosters provide superior air-fuel mixing for exceptional performance • The 20% larger fuel bowls use ribs to minimize incoming fuel foaming and control slosh • Nitrophyl floats shaped to avoid shutting off fuel flow during hard cornering. Jet extenders in the secondary bowl keep the jets covered in fuel under hard acceleration • Dual 50 cc accelerator pump circuits can satisfy large engine sizes • The one-piece 3.75”-tall aluminum body is a direct fit on either 4150 or 4500-style intake manifolds • The throttle arm includes all popular transmission kick-down take-off points • Vacuum ports for PCV, power brake, vacuum advance, and transmission modulator for a direct bolt-on installation • Built-in provision for a GM three-wire TPS • Four-circuit billet metering blocks use industry-standard-size screw-in bleeds and jets • The intermediate fuel circuit provides extra fuel just after the blade passes the transfer slot for incredible throttle response • Air bleeds on top of the carburetor provide a quick way to fine-tune each fuel circuit • The high-speed fuel circuit has two air bleed paths – one for lower and one for upper sections of the main well for greater fuel ratio control at high RPM • The idle circuit features interchangeable jets and four mixture screws to create a smooth, clean idle, even with the biggest camshafts • Dual power valves allow leaner cruise and add fuel as you get deeper into the throttle for excellent street-performance driving. Protection circuits prevent backfires from damaging the diaphragms
