Just what does the velocity stack do? If all one has is a air intake and exhaust mod will it help?
The all-new VR Velocity Stacks are the solution for the poorly designed GM throttle-bodies. Installation takes just minutes. Increase power output throughout the entire RPM range, improve throttle response and increase gas mileage. There is no more need for a ported throttle-body! Basically, what the VR-B3 velocity stack does is remove any and all turbulence and straightens the force full airflow coming in from the intake system. On the dyno it actually showed a nice gain especially in torque throughout the RPM band.
Good question. I forgot to post our findings on the dyno with the VR-B3 velocity stack. With the VR-B3 velocity stack, we saw a 1 rwhp increase and a 3 rwtq increase. Keep in mind that that was the max value output on the dyno graph, but in some parts of the dyno graph pulls we saw upwards of 5-6 rwtq with the velocity stack over the dyno pulls without the VR-B3 velocity stack. It does work and for $29.95 extra, it is well worth the money!
