Another repeat dyno customer, this time he needed velocity stacks installed. Being a street racer, this customer is trying to get every ounce of horsepower out of his Suzuki GSXR 750. Do you think the velocity stack install was worth it?

From what I have learned, the golf ball dimples create a boundary layer of air, which makes it more "slippery" for the intake charge. I would like to see a set without the dimples tested.

$37/gal for MR12 Ohhh man. That's some spicy pricey. Basically the intake velocity stacks function very similarly in principle to why 2-stroke engines have traditionally run the stomach-shaped exhaust headers; it has to do with the pressure pulse traveling back and forth both in exhaust systems and intake systems. When an intake valve opens and shuts, a pressure pulse travels back up the intake opposite the flow of air at a given velocity, and rebounds inside the confines of the airbox. Changing the length of the stack ultimately changes the timing of that pulse wave in the airbox and throttle body, affecting efficiencies at a given RPM range. Hence, high revving engines usually have pretty short stacks and bikes built for lower RPM power have longer stacks. Yamaha has designed a 2-stage stack to open and shut based on engine RPM and load, to make the power curve a little more flexible. Most automobiles on the road these days have a 2-stage intake system in the plastic intake manifolds, to switch to short runners at higher RPM and back to long runners at low rpm. It has everything to do with the pressure wave going in and out of the engine intake. Engines are an air pump, but airflow through an engine is anything but constant and smooth. It's really a very quick successions of gulps, with pressure waves in/out of both sides of the "pump."

"Better" Velocity stack really help for the close-open throttling,it make the air enter faster,cause it make the air more laminar... IMHO the wide open throttle not so much different... I got so many riders ordered the long one....rather than the short...they feel the torque delivery is smoother,and you can easily control the throttle mid corner...less peaky

@@AndrewNoronha-cb2gy Depends. First, most people aren't actual racers. They wish they were, but most aren't. Also, how much time do you spend at peak? Versus coming off a turn, or riding around in the Mtns, where that midrange punch coming off the turns translates to faster times? Been riding a long time... 400k+ miles on street and track, over a period of 27 years and spanning 31 bikes... I have considered stacks, but when I would talk to my tuner about it, he would point out that they just move a few HP from one part of the rec range to the other. Lots of guys call themselves racers, but they turn out to be straight line guys playing on the interstate... A lot of them just like chasing a number on a dyno sheet... But when you think about where most riders spend most of their time riding, the midrange is usually a better place for that power than a couple ponies that they rarely touch up top...

I think you should do some serious R&D on the velocity stacks to get decent power out of them, maybe for the street they aren't worth it but for the track it surely is, at the track you spend alot of time at high rpm's in lower gears,midrange is really important for the street, you should take care of that next time you make them for the roads!!

Every video I have seen in regards to velocity stacks on numerous dyno's show the same thing. If you have an indy car they would be a worthwhile investment, but losing power on the wat up the range to make a little extra at the top, looks like a net loss to me as you are slower getting up to peak power. But when you pour the liquid gold in the tank, the fuel is gaining you more than the stacks.
