Unlock Your GSX-R1000’s Potential with Carpenter Racing Velocity Stacks!
If you’re looking for one of the simplest, most effective upgrades to boost your bike’s performance, it’s time to take a serious look at Carpenter Racing Velocity Stacks. Designed specifically for the 2017 and newer models, these stacks are the result of extensive dyno testing and real-world performance tuning.
Why Velocity Stack Design Matters:
Not all velocity stacks are created equal. The length, taper, and radius of each stack play a critical role in airflow dynamics and power delivery across the RPM range. Carpenter Racing stacks are not only equal length – ensuring balanced airflow to each cylinder – but also the proper length to optimize pressure wave tuning and improve volumetric efficiency at high RPMs. This means better throttle response, more midrange torque, and increased top-end horsepower.
Precision Taper and Inlet Radius:
The taper and bell-mouth radius aren’t just aesthetic features – they’re essential to performance. Our stacks feature a specifically calculated taper that accelerates airflow without causing boundary layer separation, maintaining high air velocity into the intake ports. The inlet radius is optimized to reduce turbulence at the entry point, allowing for smooth and consistent airflow that supports maximum cylinder filling.
Whether you’re chasing lap times or dyno numbers, Carpenter Racing Velocity Stacks deliver race-proven performance gains that stock components simply can’t match.
Key Features:
Whether you’re chasing tenths at the drag strip or just want your street bike to feel more alive, this upgrade delivers. It’s a smart, affordable mod that works great on its own—and even better when paired with other performance upgrades.
Bottom line? If you want noticeable gains without digging into your engine, Carpenter Racing Velocity Stacks are a no-brainer. Simple install, serious results!
