• Edelbrock VRS-4150 Race & Performance Carburetor #1308-E85 has features that benefit both racers and high-performance street enthusiasts.
• 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.
• Two auxiliary idle air screws allow users to change idle speed without moving the parked throttle blades away from their ideal position.
• 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 great street performance driving. Protection circuits prevent backfires from damaging the diaphragms.
• Annular Boosters for superior air-fuel mixing.
• Custom billet metering blocks flow more fuel to provide the ideal E85 AFR.
• Custom metering blocks and extra-large fuel jets specifically built for E-85 applications.
• Provisions for TPS Sensor, multiple vacuum take-offs, and trans kick-down attachment for ease of use in street oriented 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 50cc accelerator pump circuits can satisfy large engine sizes.
• The one-piece 3.75-inch-tall aluminum body is a direct fit on either 4150 or 4500-style intake manifolds.
• The throttle arm includes all the popular transmission kickdown take-off points.
• Vacuum ports for PCV, power brake, vacuum advance, and transmission modulator for a direct bolt-on installation.
