- Precise Fuel Injection Control: 20-12 accelerator pump cam will allow you to "tailor" accelerator pump performance to your engine's actual requirements. They include cams that have a different shape or profile to give different results. Each cam’s lift and slope profile regulates fuel delivery volume and timing, eliminating engine hesitation during sudden acceleration and optimizing power response.
- Performance Tuning: Cam "lift" directly affects the accelerator pump stroke, and, therefore, pump capacity. Ramp profile or shape controls the "timing" of the shot. A steeply-rising ramp shape will give a fast, heavy fuel shot right off idle. Conversely, a gently sloping ramp will spread the pump action over a longer period of time.
- Wide Compatibility: Accelerator pump cam for Holley 2300, 4150, 4160 carburetors, widely used in classic cars, modified vehicles and V8 engine setups for reliable performance. Ideal for street driving, mild racing and daily commuting; adjusts fuel-air mixture for improved combustion efficiency and smoother throttle operation.
- 8 Color-Coded Options: Covers a full range of fuel delivery levels from light to extra heavy (black, pink, white, red, green, orange, blue, brown), Adapt diverse engine displacements and driving scenarios.
- Durable Construction: The carburetors accelerator pump cam kit is crafted from premium materials to withstand high engine temperatures and frequent use, ensuring long-lasting stability in carburetor performance adjustments.
