Price is absolutely crazy for a couple peices of aluminium. $100 per 1 horsepower. Like the gains tho for smthn so simple. But is it truly worth a nickle? Wait a year or two for a price drop
I don't understand why then the velocity stacks don't come shorter from the factory already. I guess factory team is trying the best to get most power out, while considering the lifetime of all parts to be in good equilibrium. Otherwise what would hold factory off doing so?
I have a 2020 kawasaki zx636 6r. Gonna put those Venturi Stacks on it. When they go on,,, Do I need to retune the bike. I'm sure it does but need to truly know. Bike has been flashed. I have a PC5 that was taken off when flashed. Has a 2 Brothers slip on
I have a 2018 gsxr 1000 that I just installed these velocity stacks on. I was told to add 5-6% fuel from 13500-14500. No fuel needs to be added thru the midrange?
Do you ride? HP per ton. If you had a car with 500 hp that weighed 4,000 lbs (2 tons) that's effectively 250 hp per ton. A bike is 350-450 + rider. A 180 hp bike (we'll go even at 500) x4 is 720 hp per ton. So 7 hp is effectively 28 hp, and people will buy a cold air intake at $300+ for 5 hp. If you're trying to get everything out of your bike these are well worth it.
@@KingBob3456 I had the name LONG before the car OR that stupid movie. If you want real power these days, electric is where you'll find it. I have no doubt there will be soon, if not already, an electric bike that can leave any ice bike on the line like it wasn't even running.
Okay then HP per dollar and you will see it's very worth for those who race or do mile or even half mile events. People get full exhaust and don't get the returns that this would (if they work on the streets because you don't race on a dyno
@@morthskarampouzouklis8561 That is completely inaccurate. Fuel is injected below the velocity stacks. ETA: The rim roll on the top of the stack wouldn't effect the top injector hitting the side of the stack.
@@rickden8362 at 1:58 of the video you can literally see the fuel rail with the 4 injectors siting on top of the airbox and velocity stacks.Again you need to read and have some more knowledge how these bikes work.
What a moron 🙄 So with your vast experience of Supebike engines and racing, perhaps you could tell us all why Yoshimura chose to run MWR on their Superbikes instead of their own? I’ll wait 👍
Thanks Leah and HTP Performance...the Venturi velocity stacks was well worth every penny!
What did you put them on
loctite optional, think you should use it to prevent the bolts coming out and going onto the cylinder

Well, they're sold as street bikes. Maybe that gave them the right powerband they needed to meet emissions.
The stacks are not equal lengths for the cylinders, will that not cause a lean or rich condition for two cylinders?
It looks like the stock ones were too. Perhaps the runners are longer on the shorter two trumpets?
@@danburdiek2697 yes that must be the only reason I can think of too
How are you loosing torque between 10k & 13k and the power curve is still above?
Nice catch, mate.
Mathematically, it makes no sense
Its basic engineering when rpm rise up from one point HP climps while torque drops on high revving engines
445$ lol xD

Very nicee comparison. Direct to the point and no nonsense blah blah blah
Where can I get some velocity stacks for my 2007 Suzuki 750
Wonder how they stack up against the carbon smith and Turn 13 ones 🤔... stack up... see what I did there lol 🏍🏁
Any experience with zx10r gen5 ???
para demostrar esto se debiesen hacer por lo menos 10 pruebas en cada caso y sacar un promedio y una desviación estandar
I’ve got my 7 hp Leah my boy did too we are very pleased
Did you have to make any adjust to your AFR?
Yes I had to get bike retune by my tuner
My Bike made 181 on pump and 189 on mr12 my boy bike made 183 on on pump and 193 on mr12 that’s cause we have different pipe
Before my bike made 174 on Dyno when I put htp stacks in made 181
@@justintillett4159 what yr bike and how did the bike accelerate afterwards
Excellent presentation Leah.
Thanks, Trev!
What about air filters? Make a video air filters and stacks combined and stand alone...mapping & stock
We've more videos planned... including air filters.
Venturi or carbon smith?
Nicely made; but wow expensive.
The manufacturers spend a huge amount of money on R&D getting the best out of an engine for every situation on the road. So why mess with it?
What the the actual hp output peak for stock V billet?
Have you dyno’d the MWR stacks? I’ve seen a rich spot in those on my logs and wondering if there were any fueling changing between your dyno runs
The bike was tuned with the stock and with the Venturi stacks. We have ran the MWR stacks and didn't see results like these.

Just less than $500?!? For those? FOR 7HP?!? Y'all crazy.

hope you done more than 10 runs per installation
Haahaaahaa valid point
Looks good
Aluminum stacks over 100$ a piece wow
Hah for an ecu flash there are more hp's for less money.... take that on your own bike. Thats rodiculous
I was under the impression that best tech was trumpet lips should be rolled to 180*.
Not possible these bikes has 8 injectors and the 4 of them sit on top of the velocity stacks spraying fuel at high rpm
@@morthskarampouzouklis8561 Not exactly sure how that prevents rolling the stack tops 180*.
@@rickden8362 The fuel will be sprayed on the walls of the velocity stacks instead of the intake ports?

Does it works on a not ECU flashed bike with catalytic converter inside?
No. Without the ECU flash the throttles will close up top.

I wonder if that profile is para/hiperbolic...
what stops someone from just 3d printing those out of plastic
its funny you mention that! i am 3d printing my set right now! got about 5 hours of print time left then its time to install!
