VRS-4150 Race & Performance Carburetor # 850 CFM

Description

Edelbrock VRS-4150 Race & Performance Carburetor #1308-E85 has features that benefit both racers and high-performance street enthusiasts. 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 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. 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.

When you design and sell the best-engineered performance products in the world, you have to have a rigorous testing program. Why? Without adequate testing, there's no way to stand behind your product with confidence. That's why every product we design and sell at Edelbrock is tested and approved by Edelbrock engineers in a real world environment on state-of-the-art equipment. Our three Super Flow computerized engine dynos are capable of measuring 11 separate engine variables up to speeds of 12,000 rpm. For 2007, we added a new Super Flow SF902 engine dyno. It's fully automated and programmable to simulate various driving situations, and is equipped with WinDyn software for the very latest in testing equipment. For real-world tuning, there's our Super Flow model SF-840 eddy-current chassis dyno that can handle up to 1,000 hp at the wheels and speeds of 200 mph. When all testing is completed, the results evaluated, and the part has passed all performance criteria, then, and only then, is the product deemed ready for production. These precise testing procedures are applied to the entire Edelbrock line for performance that's guaranteed. Edelbrock test vehicles are driven by Edelbrock engineers and employees to get a "real world" feeling for the performance improvements. Our products are also tested and used by professional race car teams and drivers. Working with these talented individuals is just another extension of our research and development process so when we say "proven performance" we really mean it! Top racing teams in all forms of motorsports rely on Edelbrock to produce parts that they can count on to win races and championships. Further underscoring our commitment to the racing community, Edelbrock is the only aftermarket intake manifold manufacturer licensed by NASCAR.
