Chris ain't no fuel going over those stacks... The heck you talkin about??

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."

@Thomas B I guess if you're racing on circuits and have a lot at stake.

Excellent video. I learn more about tuning parameters every week. 🏆❤🏍

This is really informative and entertaining man

Great video! Let's see that ecu flash from the 2022 Busa though. Got us all drooling and simping your channel just waiting. I'd pass on stacks. No one lives in the peak rpm range. He could get way more out of that bike with actual motor work.

Very nice airfilter and velocity stacks! Try to little bore out throttle body and bigger airbox and big bore funnels... highest hp ever! I'm deaf and you are one of my most favorite tuners! You are really top on my list for enjoy to watch your videos for tunes!

It shifts the power!!!! Details thank you sir.

good info on the air filter. little things like that help the guy who wants to spend money on there road pride and joy. :)

I can’t wait to bring my 2019 Ninja 636 in here. So far I’ve got the Graves WORKS2 Titanium (High-Mount) exhaust system installed, just ordered Graves titanium header, Graves DNA filter already installed, I’m grabbing some Graves velocity stacks next, and I’ll be in for a full dyno tune. I’m after 126-130WHP on 93 pump shell gas. I hope I get it!!! Fingers crossed.

"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

I really like this 2022 HAYABUSA And the contest of the your KZread channel is very nice the content wont get any other KZread channels i am really a greate lover of the 2022 hayabusha it is my bream bike

Am I the only 1 who noticed dyno at beginning was 135 on pump gas. And he ended at same with the stacks

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!!

I would love to see this test made on a f900r, 790 or a mt07.

I don't see the dimples working like you said because there is no fuel in the velocity stack it is sprayed in below that so not sure how the dimples will help but I do know that velocity stacks do make a diff.

Hell yea

Never been a fan of stacks myself. It was explained to me years ago that they don;t make power, so much as move some of it. You gain up top and lose somewhere else... Glad I never wasted my money on them.

@@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...

So I talked to you about 7 months back or more about Velocity stacks on my 2012 750. At the time there wasn’t anything out for 750s So watching this video on those stacks I’m saying not worth the money. And I thought it would be better to have different height and also they need to be smooth I think.

Awesome vid bro so I brought all these thumbs ups for ya algorithms Mate 👍👍👍👍👍👍👍👍👍👍👍🔥💯🙏

why do the center ones have those longer bits?

Those 750 Gixers” Was only 750’ to Beat My’ Kaw 750 Turbo”!! Still Bad a zzz. Whooo!

I have a 2018 GSXR-750 I personally would pass on them. I only street ride, if I really wanted more power I would move up to a 1000 then maybe I might get them

Hi Chris love your channel I watch it all the time I've got a question and I can't find anything about it on KZread so I know if anyone would know it would be you If I was going to buy a GSXR 750 any year model and I wanted to put let's just say upright handlebars on it maybe something similar to the GSXS 750 clip-ons is that possible ? The reason I'm asking about this is I believe that I would like the GSXR 750s horsepower better than the GSXS but my back tells me that I would need a better upright seating position if this is possible I would like to know Thanks

I think if the stacks were dragging in air directly from above, instead of an angle, it would change again.

So is MWR race filter better or not as good as sprint cause that’s what I have and my stacks are factory pros and these sukkas are short

Why didn’t y’all remove the 2 talls

On a golf ball the dimples create a laminar flow. Which is a smoother less resistant air flow. I would assume it would be the same here.

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.

So simply put, this mod is hardly worth the money. May be somewhat beneficial in street/rolling races, but if the bike is a circuit weapon, it's better to be left alone with stock stacks and more linear power curve. In any case, the best and cheapest mod to make the bike go faster would be saving money on food and stop stuffing the stomach of that black hunk owner 😂
