Two turbine engine powered race boats do some testing on the lake. These boats normally race on river courses, so a nice calm lake is a piece of cake, but we're just doing a quick test of the setup before heading off to race.
Maximum speed is not the goal here, but both boats went just over 125 MPH on this day.

350 lbs, 1250 Hp, and longer service intervals between overhaul. Plus, the T58 was designed to reliably produce 1250Hp for hours, days, weeks at a time. The piston engines have been highly tuned and hot-rodded to get near that level, and are more highly stressed. Also, yes, a very large cool factor, don't you think?

@spiderbass4hire474 Год назад

Always thought that was the biggest advantage of a turbine. Its designed to produce that kind of power all the time. A completely outrageous Hemi bored stroked supercharged and maybe sneak a cup of hydrazine into the fuel will produce 10 times the power but only for 5 seconds. And the a complete rebuild in less than 90 minutes. I like to bend wrenches myself but that's a bit much. And then there's no trip to the racetrack that's complete without a pickup truck box of broken parts. Although I the Yanks should have come to us for the Turbine/Diesel setup on their LCSs. Canadian navy has been making that work for decades. Seeing a full size destroyer coming up on plane is pretty impressive. Even more so when you don't tear up the gearbox.

I never grow tired of hearing these boats running! Just reviewing some classic video on a Friday night & thanks again Jay for all of the effort you have put into sharing. DD

@jreid641 6 месяцев назад

Thats so cool! I love the sound of jet engines spooling up!

@AgentJayZ 11 лет назад

A few days after this little test on the lake, these boats were on the river,running over 135 mph according to GPS.

@brianhudgins990 Год назад

What incredible engineering. Beautiful.

@davidtaylor5007 11 лет назад

I'm amazed the water jet can deal with that kind of power! Love these videos!!

@AgentJayZ 11 лет назад

There are many training programs to make you an apprentice gas turbine technician. I did that and other things. If you built models of aircraft when you were a kid, and have to stop what you are doing to watch an airliner take off, you'll do fine.

@dirtyrottenchristos 5 лет назад

You sir have my respect for your modest behaviour

@brianhudgins990 Год назад

That is literally flying. On the surface. But it's flying. You guys should be proud. Good night.

@lerkzor 11 лет назад

that looks like so much fun! Thanks for sharing this, Jay.

@gordonanderson3111 6 лет назад

So very cool to see turbines going into boats. Our Berkeley jet pump boats that a frend of main and I had were powered by big V-8's - very very loud yet only about half the top speed!

@AgentJayZ 11 лет назад

The engine makes no power at idle, so letting off the gas pedal causes a huge deceleration from speed. Also this design uses a free power turbine. Please see my video on power turbines.

@vincebermudez869 4 года назад

That is one bad ass ride!! Congrats.

@vppnbrent 6 лет назад

That certainly catches you off guard hearing the electric fuel pump go on then the turbine spins. Cool, very cool. Very nice boat. Congrats.

@AgentJayZ 6 лет назад

The second thing you hear in the starting sequence is the electric starter motor engaging.

@vppnbrent 6 лет назад

I was a Jet Engine mechanic in the Navy and understand it. Again, very nice boat.

@AgentJayZ 11 лет назад

These are shakedown runs to test out boat setup. And Bob is a very experienced race boat driver. Timid is probably not the best word to describe his driving...

@matrix777able Год назад

Awesome wallie fishing in that lake 👍

@AgentJayZ 11 лет назад

Allison/RR 250 C18 is 320 Hp. C-20 is 400Hp. They both weigh about 150lbs, and have an output shaft speed of 6000 rpm. They would fit in a large, modified Jet-ski. In Jay Leno's bike Y2K, I think the engine is a C-20...

@MrJdsenior 6 лет назад

I've often thought that a wing up front with some stabilization would be nice to stop porpoising and blow overs and the like. Looks really nice on the water. Like SERIOUS fun!

@AgentJayZ 11 лет назад

New parts are expensive for both. On the ground, the FAA doesn't care, so many owners use the parts until they wear out - something you can't do in the air. Your little turbine will be cheap because it will be shagged. It will still run, but the FAA inspector would call it garbage.

@AgentJayZ 11 лет назад

These are helicopter engines, and the helicopter fuel control is used. The pilot selects a percentage of main rotor speed ( usually 100) that he wants, and the fuel control adjusts the power output of the gas generator to keep the power turbine ( which is mechanically connected to the gearbox driving the main rotor) within 1% of the selected speed. Helicopter fuel controls are incredible - if the boat were to jump out of the water, the PT speed would not change at all.

@Talisman-tb6vw 10 лет назад

I love that sound when the starter has the compressor up to speed and you add fuel - whoosh :D

@peterolsen9131 5 месяцев назад

tac tac tac tac WUMPFT!

@AgentJayZ 11 лет назад

The minute or so of idling as the boat comes in to the trailer is plenty to stabilize the engine before shutdown. I've inspected the turbines of both these engines, and they show no signs of heat stress.

@skunkwerxj.p.lthermodynami305 9 лет назад

You guys are so cool! I'd love to pay a visit some time. Keep up the crazy cool work!

@dezertraider 6 лет назад

Thank you J,,Great video,,TY73s

@AgentJayZ 11 лет назад

The driver controls the angle of the forward wings with an electric screw-jack actuator. The up/down buttons are on the steering wheel. What he does with them and why... I think that is proprietary team information... and I don't know anyway.

@AgentJayZ 11 лет назад

The T58 has an integral reduction gearbox on the PT, which turns the roughly 18,000 rpm into an output of about 6,000 rpm. A helicopter then feeds that into another gearbox that turns that into main and tail rotor drives at their appropriate speeds. Instead of the helicopter main gearbox, the boat has an otherwise conventional jet-drive system which can be driven by a piston engine running at 6000rpm, or by the turbine engine.

@dirkdiggler1242 6 лет назад

AgentJayZ so my 87 octane pumpfuel injected 3.0 Yamaha DOHC that churns out 8,000 rpm would be a perfect fit for the flying boat....?????

@Chance-ry1hq 6 лет назад

AgentJayZ who cares! Get that noisy piece of shit off the lake!

@jackfrost2146 9 лет назад

Is the airfoil elevator? canard? on the front controllable while on the move? If so, it's something that's been lacking on high speed boats for ever. (as far as I know).

@AgentJayZ 11 лет назад

Actually, they are adjustable via a control in the cockpit, and are used to adjust the attitude of the hull while under way. Sometimes they are used to lift the front in order to provide a better inlet angle at the pump inlet. Sometimes downforce, sometimes lift....

@dougfzrr 6 лет назад

Hell of a jet pump to handle all that power!

@AgentJayZ 11 лет назад

These boats race on rivers. Racing is racing, not just going fast, but as fast as possible... Yes, they can wipeout, and sometimes end up on shore, upside down. The roll cage helps in those situations.

@XLR82TheMAX 10 лет назад

I really liked your clip.

@64jorthom 11 лет назад

Hi, there is like a spark nois when starting the engines. Am I correct

@allergic2cubicles 11 лет назад

Amazing boat, great park job too!

@GrantW74 11 лет назад

Exactly....I was taking note of the Gear Box to the jet drive made by the same company that makes V drive gear boxes. Interesting, I was involved in water ski racing here in Australia for over ten years and for the Unlimited class to produce engines to be able to get to 1250+HP took a great deal of Money and effort. The Ski Race boats today are powered to 1500-1600 Hp with stern drives and are lucky to acheive 130MPH with rebuilds only after a few hours. Thanks for responding Mate.

@AgentJayZ 10 лет назад

You get the hull from Eagle Performance in Alberta. You supply the T-58 on your own Pump, jet nozzle, Casale box, seats, steering, batteries, bilge pumps, fuel pumps, oil coolers,and gages are all commercial items. Then you take about 100 hours assembling your boat. Then spend many hundreds of hours testing and sorting out the setup, making sure it works. This particular boat, no longer wearing CDN1, but number 357, is for sale.

@Baywarrior707 6 лет назад

Where is the listing located

@goldendredger 6 лет назад

Great boats and awesome passes. Questions for you? Is the conard or forward wing on a gyro to control the hull attitude or is it human controlled?

@dieseldog00 10 лет назад

Miss GEICO used a fuel combination of diesel, jet-A and 93 octane gasoline. What do you use?

@arielpombo 11 лет назад

smooth water, smooth engines, smooth passes!! great!!!

@ThePondmeister 11 лет назад

How and what over rev protection if any is required like for example if the water intake comes out of the water and the load comes off the engine?

@daniel2001 11 лет назад

Hi Jay, thanks for taking the time to make these videos, find them very interesting. In a marine environment (such as when used as propulsion engines in a warship) does the salt in the air have any impact on the performance of a gas turbine? Specifically, would salt deposits build up in any part of the engine? If so, could these be removed with the engine in situ or would the engine need to be removed from the ship and cleaned as part of an overhaul?

@fourbypete 6 лет назад

I hate myself when I love something really impractical. I imagine it's a lot of work to maintain and run boats like that. But I Fucking love it.

@AgentJayZ 11 лет назад

One of these boats was clocked at 136 on Labor Day.

@pwengineering9070 6 лет назад

Wow, an on -board starter....well done.

@Alilretard1 11 лет назад

I love the rooster tail that comes off the back of these things.

@daniel2001 11 лет назад

Thanks for clearing that up.

@v.e.7236 6 лет назад

Got the opportunity to ride in a cat powered by two blown Hemis on Biscayne Bay, Fla. up to 200MPH. Not sure how many folks have experienced speed on water, but its a completely unique speed experience. Was absolutely the most fun I've ever had in a boat!

@TheDave31london 10 лет назад

this might be a really silly question but could'nt you mount the turbine higher so you could add an afterburner for extra straightline speed or is that against the rules?

@PanceriMarco 11 лет назад

JayZ nice video, and great job in that t58 last summer =)), i wonder if the tje outlet side up (for obvius reasons... you couldn't turn it donw...) helps the stability of the boat, to sit fermly the back of the boat on the whater, or if it makes no diference . and one more, the outlet has enough thrust to help move the boat, or this thrust is overtake by the whater jet from the propulsion system?... thanks!! you do amazing videos, and share priceless knowledge!!!

@N3QO73 11 лет назад

Up and out of the water at 7:43. Thanks for sharing!

@sbkenn1 8 лет назад

Is the canard automatic or manually operated to prevent back somersaults ?

@giancarlomoscetti215 10 лет назад

Those boats seem perfectly set up.

@BigZeus 11 лет назад

Do those use a propeller or impeller like a jet ski?

@YOUNGSTERS-JETS 11 лет назад

Crazy Stuff !! Lovely lookin boats :)

@powershop1903 10 лет назад

Hello! Great video! I was wondering what diameter the jet pump is on these boats? Thanks !

@Hossman757 6 лет назад

Bad ass. Sounds awesome.

@AgentJayZ 11 лет назад

The exhaust is at the back, and this isn't really a v-drive. The T58 would be very happy to turn a stern drive.

@livvidd 9 лет назад

Wow awesome boat. Sounds like a tie fighter when its tearing past.

@WillArtie 7 лет назад

Yeah I was just about to leave that comment too - but I looked first to see if anyone else had made it. The pass from left to right after 7:30 sounds pretty damn close to a Tie Fighter! In fact, I'm gonna find some tie-fighter footage on another browser tab and watch it with the sound turned down and this turned up just to much around and convince myself! And then after THAT I will start doing some work. Absolutely.

@rlvilleman 11 лет назад

Awesome video Jay! I come from industrial side of turbines, and was just curious if vibration monitors are bypassed on a rig like this? Or are any used at all? Thanks. Couldnt find info anywhere on the matter.

@klesmer 11 лет назад

Are the canards preset or are they adjustable while in flight so to speak by gyros maybe?

@MrWildfire78 10 лет назад

wow hey guys whats the top speed of this things? this are so cool..

@reldew76 11 лет назад

Hey jay awesome video! When you work on an engine that is going to be used for a ground/industrial installation, is there a price difference in parts? I'm asking because a friend of mine was telling me I could get a small turbo jet engine for cheep (ie, $5000) because the engine was a ground based unit, so all the liability concerns, with aviation engines does not exist.

@wrthndr69 11 лет назад

does it have a shaft or do the exhaust gases drive it?

@rodd8125 11 лет назад

Wow, wicked cool. This may be a dumb question but what good does a roll cage do on the water? That there in case you run aground?

@poil27 11 лет назад

super nice as usual Jay . no competition last year so you made your own! do you think the other teams would have upgraded to turbine power this? best wishes for this year season ,godspeed .

@masterpubo 11 лет назад

What is the use of the Front Wing ?

@entrad157 7 лет назад

That's wicked! I want one.

@AgentJayZ 11 лет назад

The T58 used in the Seasprite helicopter has a two-stage power turbine, air cooled nozzles and blades in the gas generator turbine, and other mods to help it produce over 1800 reliable Hp. Yes, everybody wants one of those. To run a race boat, a quick checkup every few hundred hours.

@Sadik15B 4 года назад

If you inject water before the turbine wouldnt that give a much cooler egt and less stress and more power? Water isnt scarse where it runs as in the air.

@chucknorris9821 11 лет назад

how starter works on that engine

@badazrod 11 лет назад

Very, Very Cool! Thanks!

@stats432 10 лет назад

Holy F.U.C.K! When that throttle was first floored I was instantly transported to my happy place, I envy all you lucky bastards who get to drive that sweetheart, thank you for posting this awesome video!!!

@WE2TECH 11 лет назад

ok i have zero exp with turbines or jet nozzles, that said it looked like there is no neutral just direct drive, the turbine starts and spins jet. so to stop you must turn off the turbine ?

@dieseldog00 10 лет назад

Yes Miss GEICO Racing had problems with saltwater ingestion. They solved it with a huge intake filter and never had ingestion after that.

@AgentJayZ 11 лет назад

28VDC motor driving the main shaft directly via a one way clutch

@mordacthedenier 11 лет назад

Have you guys ever used a g-meter or GPS logger to measure the boat's acceleration?

@AgentJayZ 11 лет назад

Salt spray is bad, both for deposits that destroy aerodynamic blade profiles, and because it can really cause corrosion. The ships using large gas turbine engines have huge amounts of volume devoted to inlet purification. Removing dust, and mainly salt spray. Also the marine engines have extensive use of protective coatings and paints. Race boats, like racing vehicles of any kind, lead a tough life, and are very maintenance intensive... or they don't finish.

@PMPiper86 11 лет назад

just the intake grate in the water!!! awesome!!!

@supersavage123 11 лет назад

crazy very crazy would love a ride in one of these beasts wonder how many gs they pull when they open them right up

@Flies2FLL 9 лет назад

If the sound of that thing going past doesn't raise the hairs on the back of your neck then you are probably clinically dead~

@MrThenry1988 6 лет назад

Like the wing up front.

@ztwntyn8 9 лет назад

I grew up around a 90 mph jet boat but wow is this thing obviously godlike.

@AgentJayZ 11 лет назад

it's not that simple. There are no drivelines made for old helicopter engines in boats, so you do what you can. These boats use driveline hardware designed for 1000Hp V8s. So putting more than that through the system can cause things to break. Making power is not a problem... getting it to the water and turning it into speed is tricky.

@AgentJayZ 10 лет назад

...As far as you know... ? You don't see the point ? No, in the unlimited class, they walk all over piston engines. You guess? Tell you what: have a look at EngineBlockTV... on RU-vid. Check out any of their segments on the NZ Jet Boat Marathon, and compare the piston boats to the Gas turbine powered ones. How do you tell in the aerial shots? The turbine boats are always in front. You would notice some lag on a motorcycle or a car, but Turbines work great in boats.

@arnoldchildress8053 3 года назад

Straight up beast

@AgentJayZ 11 лет назад

The speed is measured with GPS, and acceleration has not been recorded. Both boats did a touch over 125 mph in this video.

@Sadik15B 4 года назад

Doea this boat has 1:1 ratio output? The power turbine is designed to run a rotor. Gues at high speed using a higher gear could be faster because of the excess power. What do you think?

@SirLugash 10 лет назад

Nice video! This is using the Turbojet with a Power Turbine connected the the Screw Drive, correct? Though I wonder, wouldn't make it the boat go faster when it's using the Turbojet's engine thrust?

@scraperlol 10 лет назад

that is crazy how little of the boat is in the water.

@purplemurple1971 10 лет назад

How much does one of those cost

@lerch122 5 лет назад

i wonder if it has some type of system to automatically adjust the front wings?

@AgentJayZ 5 лет назад

It would be easier to ask me. Then I would tell you that there are two buttons on the pilot/driver s control/steering wheel. One says up and the other says down. they move the front wings via an electric screw-jack actuator.

@markkeown9532 5 лет назад

If the function of the wing on the bow of the boat is to keep the bow from flipping up - should the winglets be on the bottom of the wing?

@AgentJayZ 5 лет назад

That is not the function of the forward wings.

@chaki83 11 лет назад

dear AgentJayZ thank you for your reply and your great videos.....

@justaddwata 11 лет назад

Or just refer him to the race footage from a few months ago where the turbine clearly was dominant. Another great video Jay!

@powerstrokeking 11 лет назад

Were the batteries on "Another Disaster" a little weak?

@wiattmarlatt3252 2 года назад

Could I build a 21 foot outlaw eagle race hull into just a lake and river ripper without a turbine engine? What motor would be the best for that? Is it even possible to turn this kind of boat just into a fun lake ripper?

@AgentJayZ 2 года назад

The hull is actually designed for an American V-8 engine. Most of these hulls are actually running piston engines.

@richmanricho 11 лет назад

HOLY MOLY those things are flippinh nuts! Over 200KPH on water,,, wow, just wow

@clockman47 11 лет назад

I like that sound of start up, Do you have to let the engine cool down after a run before shut down, I'am just a long time fan of yours. Thanks Jay, Your Friend in Georga USA. Be Safe.

@chaki83 11 лет назад

they have negative AOA and used for create a downward force at the front side of the vessel.
