- Adds 6-13 Horsepower
- Adds 6-10 Ft./Lbs. Torque
- Pressure Fits Into Throttle Body
In just minutes you can add the VR Velocity Stack to your LS1 throttle body and gain horsepower and torque that you can feel in the seat of your pants. The stack reshapes the throttle body housing to greatly improve air flow throughout the entire RPM band so you feel the power the instant you stab the throttle and until you reach peak RPM. In fact throttle response will be immediately improved with this high temperature ABS unit that simply pressure fits into the throttle body housing. The VR Stack works well with the factory air cleaner and works best with the factory accordion hose. However, for even better results the VR Stack provides the optimum power gains with aftermarket intake systems.
