I lived in the Seattle area by Sea-Tac airport in the 60s and 70s before turbine hydros were on the scene. It was the best of times.... you could hear the Allison and Merlin powered boats 15-20 miles away from the lake. When they had a 10-boat flying start was really something to see 10 hard chargers heading for the starting line at 150+ mph!
Haven’t watched hydroplane racing in a long time. Didn’t realize the pistons powered boats were competitive with the turbine powered boats. That’s awesome.
@@dizzyrain985 the CFM from 20+ psi boost is huge, here is a video of a small turbo and how much air it can move ua-cam.com/video/dDncgYH5q7A/v-deo.html
@@imoovabull6042 That's crazy to think that there is a void of air when the boat is going at that speed. I have always wondered the volume of air consumed by a turbo at different psi.
I’m not insulting in any means, but a half a million dollar craft and a 10$ steering wheel. 😂 The video was awesome to watch, thank you team for allowing us to take an honored seat. I liked the adventurous part where ole’piston-pusher passed the turbine boats and then they tried to jump back into the game. Tried and true!! Seattle Lakefair would be an awesome opportunity to visit!
Just in case you don’t know but all ya all is crazy. People think road racing motorcycles is crazy but they ain’t seen crazy until they have seen this video. Well done. :)
It's not turbulence or drag, it's the turbo intakes creating regions of very low air pressure as they suck air in, momentarily the air pressure drops low enough to make the moisture in the air condense into water vapour.
Man...I wish they ALL would go back to the Allison V-12 and or V16’s alike. love the sweet sound of the torque and big V12 motors. Never liked those stupid turbine, especially here in San Diego.
Well when you take the latent drag coefficient and compare it to the resonance frequency of the engine you find the critical speed in which the turbo reaches its max turbine induction howl, the buffeting of the air through the intake plenum creates turbulent pockets which reduce volumetric efficiency. Dont even get me started on the compressor stall one might encounter when decelerating from load of the waste gate solenoid is shorted out by water.
This video just popped up in my feed. That moment caught my eye too. I had to go back and watch it a few times to figure it out. If you use the < and > keys on your Keyboard, you can go frame by frame. And if you watch, it is nothing but a simple backfire. First on the left bank, then two frames later, on the right bank. Which gives it that double percussive "buh-bump" sound.
att 0:56, is that an viper engine ?? smart choice havin em turbos in front in the open sucking in som fresh cold sea water steam to boost it upp some more.
The fact that the exhausts aren't canted at the same angle is really bugging me. Edit: I now see that the entire turbo setup is asymmetrical lol oh well
@@linusbosse285 - Of course they know what they are doing. From an airflow point of view, sharp-edged stub inlets cause fluctuating unwanted turbulence that disturbs the airflow. Look at the inlet orifice of any air-breathing engine and you will find that it is air-streamlined. (Gas-flowed). I merely suggest a possible reason why the other boats are keeping ahead...
Its just like the tracks when sprinters are running, if they were to run in their own lane the entire time, the distance traveled is uneven. So since the driver was on the outside, he had to travel the longest, while the other 2 took the shorter turn. Had he been able to take the inside, and not the outside, he would of kept ahead.
Remember other jet boats might be only using CENTRIFUGAL COMPRESSOR or HYBRID of AXIAL and CENTRIFUGAL COMPRESSOR not a AXIAL COMPRESSOR were more superior powerful than CENTRIFUGAL COMPRESSOR or HYBRID of both.And an old jet engine has a big disadvantage than a amuch more ahead of its other designe engine's so might be the reason why piston can overrun those GAS TURBINE ENGINE BOATS well i am so surprise for the piston engine looks like it has more grip on its power than those old turbines.
Shaft-driven helicopter turbines have more low end power. Past 130mph or so the acceleration suffers heavily. Twin turbos have the upper hand in that department.
Ok ok, how much power does a twin turbo Allison like this make? I’ve read that the Rolls Royce Griffon replaced the Allison as the preferred piston engine? What kind of power does the Rolls make?
IMHO it's probably a good mix of both, their isn't as much regulation for boat design and power plants in boat racing as there is in say F1 or NASCAR so the engineers have some more wiggle room but at the end of the day you are still dealing with the unpredictable nature of the water surface which requires a skilled racer to overcome at these speeds
im no expert on this but the puffs of vapor that go back and forth between the turbos caused by pressure changes ,,i noticed the change in engine tone when this occurred ,could it be the manifold pressures are going up and down because of this causing un smooth running and a loss of power that could be available maybe ,pipe them to face away from each other
You hear RPMS change because the speed of the propeller changes as the boat porpoises up and down. You "could" probably make more power by moving the turbos, but they already make enough power as is.
the issue is the water spray back especially when going slower. but yeah even velocity stacks on the inlets would probably do the turbos wonders let alone streamlining the around the engine some too for less drag
Hydro lock. Yep. Possible. The turbines just cook themselves to death with the salt water. I was in the pits in Virginia in the late 90's and the Pico American Dream was surrounded by a cool dozen turbines, each one of which had overheated due to the intake of salt water........oooooo that looked expensive!!
@@coolhat8517 They don't overheat because of the saltwater, the saltwater gets on the blades of the turbine and causes turbine stall and if left unchecked throws the blades out of balance and the motor destroys itself. And show me one instance of an Allison or Rolls ever "hydro locking" during a Unlimited Race, all boats regardless of power plant stay clear of each others rooster tails because it can wither flip the boat, or rip it apart, hitting that wall of water @ 150+ mph is like running into concrete.
xD Funny answer...."They don't overheat because of the saltwater, the saltwater gets on the blades of the turbine and causes turbine stall...." As I said, they cook themselves to death with the salt water. The saltwater crystallizes on the blades causing temperatures to rise. Pico had all those turbines sitting around the pits with visibly burned up turbine blades. Not a single one of them actually blew apart, but I have no idea what kind of rebuild would be needed to get them working again. Never heard of a hydro lock on an unlimited hydro. It's technically possible but highly unlikely. Most internal combustion engines can swallow a surprising amount of water, and hardly notice. I would be interesting to know which engine would be more susceptible to a stall caused by a rooster tail. I've seen turbine boats get "washed down" and stalling. Never seen it happen to a V12....but then I haven't seen many V12 boats running either. No secret about avoiding rooster tails. A driver back in the seventies described it as "driving up the rooster tail" xD .....gives a funny sense of what he must have felt.
@@coolhat8517 Nothing really funny about it if you understand Turbines and also V12 Rolls and Allison engines. And you said "The turbines just cook themselves to death with the salt water." Followed by "one of which had overheated due to the intake of salt water" They don't over heat because of taking in salt water.

Thank you for posting !!
This is one of my favorite videos. Stayed with one boat and all the camera views really made for a great experience. Thanks for the video.
That's awesome you can actually see the air condensing and forming a little cloud right before it's sucked in!
Forming during on-off with gas pedal ;)
Frickin awesome
Its water
Its water that the Snails Sucking...maybe
Whats out when it jumping Hard and when it going smooth.. 😉
Very cool stuff. Love the piston powered boats.
I never tire of this video. Just love watching an Allison run all out!

Watching those big turbos 'swapping fog' back and forth was awesome!!
I loved every minute of it.
MrXenophile ffg
The starter motor has it doing 12 knots... o.o -.^
I really enjoyed the race and all the bonus angles. Great job!
Guess you don't need an intercooler when your turbos are sucking up water
Hilly billy water injection 😂😂
🤪
It is a diesel the hotter the better.
@@d.c7464 3000 degree egts no problem
It's not a diesel, it's an Allison V12.
more power to be had by re-aligning your turbo intakes. 6:28 shows the vacuum between the 2 turbos, they are starving each other.
Are you sure the air that's being forced by there by the speed he is going isnt enough?
@@dizzyrain985 the CFM from 20+ psi boost is huge, here is a video of a small turbo and how much air it can move

Lmao "starving eachother" ok buddy obviously you have zero concept of air flow
@@kickassneilum and you have zero concept of vacuum displacement. many hours working dyno's tell a far different story.
@@imoovabull6042 That's crazy to think that there is a void of air when the boat is going at that speed. I have always wondered the volume of air consumed by a turbo at different psi.
It's always good to see a piston boat. I don't have a preference: piston or turbine, but I enjoy seeing a mix.
AWESOME VIDEO
The mixture on the combustion chamber is the following one: 60% air 4.2% fuel 35,8% salt water
Always wanted to know what it was like from this pictorial vantage point, and a piston packer no less. Great video...!
The pressure cone around the turbo inlet is badass!
Thanks for the ride Jimmy
I miss the sound of a piston engine, how do you keep the turbos from sucking to much water
Chris Parker what engine do these things run off of?
Dante Keskin allison v12
They dont thats the bad part about that.
omg i had goose bumps around 6:00
awesome to see the vortex of water around the turbos, you would almost think it would hydro lock the engines
It's gonna vapour clean it 😁
its not water, its the air that is being sucked in, condensing.
I was surprised to see it was competitive . Would like to know where it finished in the heat . It's an interesting concept
An old concept too. Very impressed it's competitive. They Allison's weren't very competitive with the Rolls engines by the 80's Rolls Griffon's ruled
I’m not insulting in any means, but a half a million dollar craft and a 10$ steering wheel.

I bet he is doing close to 200 mph.
Twin Turbed Allison V12 , Thats just awesome as it gets
If I may ask why not cover the intakes with a reverse pipe on both turbos! At 2:28 you see the turbulence creating drag!
It's not turbulence or drag, it's the turbo intakes creating regions of very low air pressure as they suck air in, momentarily the air pressure drops low enough to make the moisture in the air condense into water vapour.
@@ats-3693 thank you for being informative with the question I asked.. I appreciate it. Happy new year and Merry Christmas! 🎉🌠

Availability of parts killed them
Everybody a god damned turbo expert now...
Lol 😂😂😂 and engineer's

will notcomply Not really, just noticed your not !
All I know is "shove bang blow" makes more power then "suck bang blow"
Will Notcomply there’s a turbocharged jetski somewhere out there
I raced outboard hydros for many, many years, no feeling like flying an outboard!
At 7:34-7:35 does the boat run over a previously hit yellow buoy? it flat on the course but goes under the left sponson,,,

I think he's running either an Allison or Rolls Royce V12. Old vintage airplane engines.
The fact that the exhausts aren't canted at the same angle is really bugging me.
Edit: I now see that the entire turbo setup is asymmetrical lol oh well
Yeah you can't really make it symmetrical, I've never seen turbos made the other way around
rock garrett now makes em
nelson engines has mirrored setup
SuperJlonergan ya. And there crazy expensive lol. They really do make the engine there on look so much better
Those are the biggest turbine housings I’ve ever seen. The compressor side seems normal but the exhaust side seems huge!
Excellent video! Possibly might benefit from inlet bell-mouths on those turbos, keep the mixture better regulated.
I think they know what they're doing
@@linusbosse285 - Of course they know what they are doing. From an airflow point of view, sharp-edged stub inlets cause fluctuating unwanted turbulence that disturbs the airflow.

The other boats aren't piston engines. They're using turbines.
Seems like he pulls on the turbine boats in the straights and looses in the turns. I would have expected the opposite
Its just like the tracks when sprinters are running, if they were to run in their own lane the entire time, the distance traveled is uneven. So since the driver was on the outside, he had to travel the longest, while the other 2 took the shorter turn. Had he been able to take the inside, and not the outside, he would of kept ahead.
the other ones are more aerodynamic not always about power in racing .👌
@@kanhaiwilson5859 actually they can adjust aerodynamic, front spoiler moves whit legs.

the piston boat stuck with the hair dryers. how cool is that?
Shaft-driven helicopter turbines have more low end power. Past 130mph or so the acceleration suffers heavily. Twin turbos have the upper hand in that department.
Ok ok, how much power does a twin turbo Allison like this make? I’ve read that the Rolls Royce Griffon replaced the Allison as the preferred piston engine? What kind of power does the Rolls make?
Are they not concerned about hydro locking when coming up onto plane? Seems like a prime opportunity for water to get into the turbos.
Doesn't seem to be an issue
I didn’t know it was possible to drift a fucking boat till I watched this 😂
На карасика бы поехать на ней)))))
I'm surprised that breathes open like that. Are those log style headers?
Holyfukamoly!!!!! this is hardcore.... Wobbly steering wheel, leaky hatch.. I love it.
It obviously runs good, but I would love to see a symmetrical Turbo Setup with equal pipes and an air intake for each turbo.
You can put that on your 1000hp jet boat
That wouldn’t do anything but look better. Looks don’t win races
You need some 90 degree pipes on turbo inlet . Imagine air going 100mph and doing a 90 degree to get into turbo.
water ingestion would be a problem.
Isn't it bad when the turbo sucks in too much water.. I know that the air gets hot when compressed, but still doesn't it mess with the ignition?
question. How much of this is skill and how much is the boat doing the work ?
IMHO it's probably a good mix of both, their isn't as much regulation for boat design and power plants in boat racing as there is in say F1 or NASCAR so the engineers have some more wiggle room but at the end of the day you are still dealing with the unpredictable nature of the water surface which requires a skilled racer to overcome at these speeds
Damn good video.
At about 6:25 you can see that the turbos are starting to get hot finally !!!
What keeps the water from getting sucked in the turbos
Water is not in the turbo?
Any info on the build? interested in the engine setup
It’s 5:30 am, I guess this is what I’m watching
How does water not get in the turbo?
Such a thing of beauty to see that big V12 Alison roar across the water I wish the never let those turbine engines in
great video
How much power are those big turbos squeezing out of that V12?
I'm not qualified by any means but my guess would be 4500-5500 HP all day.
Sailing right around everyone.
This has made my Saturday afternoon! Thanks for posting.

“America!” @1:17

I don't know how these boats go so fast carrying around the weight of the driver's balls cause they must have HUGE balls to ride in these machines.
Jesus cameras great vid
凄い👍😃
What's the typical straight line speed of these things?

I seriously thought I was going to die no less than 150 times just watching the video. Balls the size of coconuts for sure.
there is too much flame
in 6:02 and 6:29 :)
Its because he's letting off the throttle a decent amount
Ну это я! Когда увидел охот-рыб надзор🙂😋🤭
I'm no gearhead, but i'm curious as to how they avoid water getting sucked into the intake?
Turbos mounted sideways prevents most of the water from entering compressor
They don't, they're actually spraying water (and methanol) into the turbos.
Engine aircraft?
I wonder why it’s running so rough 🤔, maybe it’s sucked in a few to many gallons of water, just a theory tho.
Water injection
What engine rpm at race power ?
Как мотор гидроудар не ловит??
