TOTAL TORQUE: Edelbrock VRS-4150 Carburettors
TOTAL TORQUE: The all NEW Edelbrock 1306, 1307 VRS-4150 Series: A Revolutionary Leap in Carburetor Technology
We know the Edelbrock VRS-4150 carburetor series might remind you of a few others on the market. Trust us, we have heard it all: “Isn’t this just like a Holley version?” But we assure you, while the resemblance is there, the VRS-4150 series is far from being a mere copy. This series of VRS-4150 Carby’s are a ground-up reinvention, challenging all your assumptions about modular carburetors. Let us tell you why.
A veteran in the carburetor business, Edelbrock is well recognized for its unique Performer and AVS2 series carburetors. So, why would Edelbrock introduce a new carburetor series that resembles others on the market? To unravel this mystery, Edelbrock engaged with Wesley Cameron, Edelbrock Group Product Development Engineer, and Brent McCarthy, Carburetor Product Manager.
The need for a new VRS-4150 series arises from Edelbrock's commitment to provide more tunability for racers while still being street-friendly for high-performance enthusiasts. The Performer and AVS2 series have been fantastic plug-and-play carburetors with limited adjustability. However, the racing community always craves more. The VRS-4150 series is Edelbrock's response to this need.
Cameron assures us that the VRS-4150 is a universal carburetor that will work straight out of the box with little to no adjustments, just like its siblings. Despite lacking a choke, the VRS-4150 carburetor series shines due to its added tunability. However, if you are not into tweaking your fuel flow, the VRS series might be more than you need.
The decision to go modular for the VRS-4150 came from Edelbrock’s intent to innovate within the established framework of a modular carburetor platform. Rather than completely reinventing the wheel, Edelbrock spotted several areas for enhancement within the well-understood modular carburetor design. What separates the VRS-4150 from its counterparts, however, is its unique design perspective.
Now, you may be wondering, what makes the VRS-4150 series so special? Here are five reasons why it is a giant leap for carburetor technology in the performance market, at a fraction of the cost:
Increased Average Power: The VRS-4150 outperforms competitors in terms of cylinder-to-cylinder fuel distribution, thanks to its large annular boosters and likely the taller venturi, which ensures superior fuel atomization.
More Cubic Feet per Minute (CFM): The VRS-4150's ½-inch additional height allows a better venturi design, leading to greater airflow compared to a standard carb.
Leaner Cruise: The VRS-4150, though designed for racing, offers adjustability to cruise at almost any air-fuel ratio (AFR) using the idle discharge jet.
Superior Base Calibration: Like its siblings, the VRS-4150 offers excellent out-of-the-box base calibration. The only difference is that it may take a while to warm up due to the absence of a choke.
No More Starvation: The VRS-4150 series float bowls are designed to keep the main jets submerged in fuel, preventing starvation during hard cornering, road racing, or autocross.
While we've only scratched the surface of the VRS-4150's capabilities, it's evident that Edelbrock's new offering is more than just a familiar face. Additional features like dual sight glasses, drain plugs on the float bowls, a TPS sensor hookup built into the flange, and easy-to-reach air bleeds further set it apart.
With the VRS-4150, Edelbrock has pushed the boundaries of carburetor technology, delivering a product that not only looks good but also offers superior performance. Whether you're a professional racer or a high-performance enthusiast, the VRS-4150 series is a game-changer, offering a whole new level of customization and performance.
