Answered: Do You Need Velocity Stacks?
This week we answer the question as to whether or not the velocity stack is all that stands in the way of being the first ATV across the mud hole:

The only thing I ever had a velocity stack on was an EVO 2X powerboard (scooter). With that I was able to use an ADA Racing air filter with better airflow. And I added a power pipe exhaust and was able to boost a 50cc engine with 4.something HP up to 6 HP. In my case it was a big gain in a small engine, but I don't think you can get a big gain like that on a bigger engine.
