Developed through extensive dyno testing and real-world performance evaluation, Brock's Performance Velocity Stacks are designed to help optimize airflow into the engine for improved performance. Precision-machined from billet aluminum and finished in black anodizing, these velocity stacks are engineered for riders looking to maximize the effectiveness of supporting upgrades such as exhaust systems, ECU tuning, and performance air filters. Browse available applications for select Kawasaki, BMW, Ducati, Honda, and Suzuki motorcycles.
What Do Velocity Stacks Do?
Velocity stacks help improve airflow into the engine by reducing airflow disruption and enhancing intake tract efficiency. While results vary by motorcycle and supporting modifications, riders commonly install velocity stacks as part of a larger performance package designed to improve overall engine performance.
Velocity stacks are often paired with:
- Performance Exhaust Systems
- Power Commander Fuel Controllers
- ECU Flash Services
- Sprint Filter Air Filters
When airflow and tuning upgrades work together, riders can maximize their motorcycle's performance potential.
Why Choose Brock's Velocity Stacks?
Not all velocity stacks are created equal. Brock's Performance velocity stacks are developed through extensive testing to ensure they deliver meaningful performance improvements on the motorcycles they support.
Rather than offering universal solutions, Brock's focuses on motorcycle-specific applications developed through dyno testing, track evaluation, and decades of high-performance motorcycle experience.
FAQs
What is a motorcycle velocity stack?
A velocity stack is an intake component designed to help improve airflow into the engine by reducing turbulence and optimizing the path air takes into the intake tract.
How much horsepower does a velocity stack add?
Horsepower gains from velocity stacks alone are typically modest and are best measured as improvements in throttle response, top-end pull, and how the engine breathes at high RPM. Gains scale up significantly when velocity stacks are paired with exhaust, tuning, and air filter upgrades that let the engine take advantage of the improved airflow.
Are velocity stacks better with an aftermarket exhaust system?
Yes. Velocity stacks work best as part of a complete performance package. Riders installing an aftermarket exhaust, ECU flash, and performance air filter will see meaningful gains in throttle response and power when adding matched velocity stacks. Velocity stacks on an otherwise stock bike deliver more modest results.
Do I need ECU tuning with velocity stacks?
Velocity stacks can change the way air flows into your engine, so tuning requirements depend on your motorcycle and the other performance modifications installed. While some bikes may run acceptably without tuning, riders often pair velocity stacks with an ECU flash or fuel tuning to optimize performance, throttle response, and air/fuel ratios.
Can I install velocity stacks myself?
Yes. Most velocity stack installations are a straightforward airbox job that a competent home mechanic can handle in about an hour with basic hand tools. The airbox comes off, the OEM intake components are swapped for the Brock's stacks, and the airbox is reinstalled.
