I love the fact the start up is so predictable that your driver is happy to float with the current for a bit while spooling up..... and also the shots of the piston boats being left in a roosters tail! Awesome Stuff!
I have seen smoke puffs from big engines on test stands. Here I thought it was water spray mixing with hot exhaust gases. No problems were encountered.
I must say, I really REALLY enjoyed that! What fun and you guys did a great job! I am a pilot and flight instructor (watching your videos primarily for educational purposes) but I love to show my friends in the aviation industry what happens when a turbine meets the marine world...wow! Well done!
The awesome power of a turbine. I had to laugh out loud when the driver opened it up at the race start and the piston boats, while they had been in front for a few seconds, the whistle of the turbine overtook any and all challengers. Thanks - great vids
A couple of things: 1: THANK YOU SO MUCH FOR NO MUSIC!!!!!! ...I loved listing to the boats as they did their laps, and the T58 when it comes on song is pure grin inducing. 2: To those calling it unfair...sure their is a big difference in terms of their engines, but like car racing of the Group B rally days or V8 Supercars in Australia in the 1990's....you dont get faster and betters being Number 1 every time...its more fun to chase something down and innovate. 3: Dont stop being awesome....loved it.
Flipping awesome. I remember when I was a little kid all the big hydrofoils used huge piston aircraft engines, then the United Van Lines and Miss Budweiser showed up with their turbines and that was all she wrote. And so quiet.
I can NOT get over how fast that is traveling. And what a view! Watching objects disappear in a fraction of a second as it flies by. My hat is off to the drivers/pilots. Oh, and of course the sound of that turbine is sweet. Thanks, Agent J Zed, truly a remarkable boat or as "Quint" would say, "vessel".
Nice build. Worked with TF34, T56, TF100, and P&W R2800 (radial) power plants myself. At least in the aviation field. I hope the #2 bearing was tight, spinning them like that can foul up a lab seal quick. Love the boat and the turbine sounds really happy. The finish reminds me of the Indiana Gov.'s cup a few years back when I saw Miss Bud vying with Miss Madison. Unfortunately for Bernie, Miss Madison was in the lead. Some of my most cherished clips. Audio sucked on them because some rotary death trap was hovering directly overhead. I was really proud for Madison In. when their boat finally won against big money sponsorship. To my knowledge the only Unlimited owned by a city.
Thanks. Funny, I live in Indy, where Allison (Rolls Royce) calls home! They have made gas turbine engines there for years, as well as transmissions. The M1A1 tank is Allison G.T. powered, as far as I know. I have many more comments & questions on your many great videos but I won't wear you out this time! Thank you very much & regards! Darren
I remember when I was 15 living on Okanagan lake in Vernon, B.C. there was this guy who lived down the road who had a 40' Catamaran with a done up 502BBC. The next year he had a 50' Catamaran with an engine out of a helicopter. The sound I heard every weekend at 5am when the lake was like glass was priceless. He had 2 trolling motors to pull the boat back from the launch as he let the turbine fire & warm up. When he'd leave it would stand at about 20° and once it trimmed down left a wake/rooster tail the likes I've only seen at Thunderfest. What you have there is absolutely nuts and I absolutely love it!
sh*t man!...makes a little power haha...blew passed the competition like they were standing still... that being said, it's not as simple as dropping a turbine in your boat ... set up to handle that extra speed and horsepower, along with a knowledgeable crew makes it look easy...congrats.
May God Bless and guide theme home safely, Bless their Families, their Boat and their inspiration. Thanks for your teachings Ole Master Turbine Yoda. Let's have fun bring them all home safe at the end of the day and your teachings have opened my eye's. Thanks again, GB
OMG, that was every superlative I can think of. Totally outgunned the opposition and all class. That was a truly beautiful drive in a very spectacular machine. A little shaky?, nah that's horsepower trying not to be tamed. Nice engine JayZ, looks like to be competitive they all need to visit Jet City?
Thanks for showing us. 120-130 mph on a river is amazing but fun only (although I am a piston guy). I didn't see a turbine on a boat ever and couldn't get the grin off my face for at least 15 minutes :-) New subscriber here, also for the technical vids. Much appreciated. Regards from Germany
Recently, a timed out ( meaning in need of a full overhaul ) T58 sold for 400,000 CDN. To restore that to aviation servicability would be another 2 or 3 hundred grand in parts. ... You said perfection, right? To find a tired , thrashed, worn out scrap heap that would not be safe to even start might cost you 20K, to restore that to perfection... it's known as BER... cheaper to buy a new one.
8:00 at first I don't see the other boats, then their rooster tails appear and then fade into the distance. WOW this thing is a beast! Imagine a nice calm day fishing and then this monster roars past...that's how UFO stories begin!
Hey Jay! Awesome video! I want a gas turbine engine like the T-58, but only 1/2 that power to play with!! Thanks for the work you do & I watched the whole ad before the video!
Wow. That is really something. I meet up with the owner of a steam museum just south of Palmerston North in New Zealand a few years ago. Talked about the steam turbine/generator used in the Golden bay cement works in Takaka that he now has. He said they used to spool up the turbine with minimal steam quickly, The energy used in getting there was small, 2 or 3 percent. But once synced with the grid they could open up full throttle right away. The efficiency of the turbines stood out when you looked at the mass of the rotating weight.
v8 scream and scream but not move, that's why i love turbine engines, they whistle and runs fast as hell (way better sound, much more tech and give more feeling of power)
They're too much competition even for the Allisons and Merlins from world war 2 fighter aircraft. But they put up a fight. That reminds me, I want to rewatch the President's Cup when Oh Boy! Oberto beat Miss Budweiser again, this time in a straight up match. Seems like a 10 - 15 second lead. T58s turn 6,000 pound watercraft into 200 MPH rockets.
There is no afterburner. There is a reduction geabox after the on-engine SDG, or speed decreaser gear... it has a separate oil supply and pump. Maybe you're seeing that.
The Gnome is essentially the same engine. The T-58 is a license-built copy of the RR Gnome. The fuel control of the Gnome is more problematic in trying to adapt it to a home built race boat. The engine featured in the series is a T58 -8F. Yes, the -16 is much sought after, and hard to find. Since the water jet drive system used in these boats was originally designed for about 500Hp, I think the jump from 1250 to 1800 Hp will result mainly in more broken parts...
There is already so much power that I don't know if more would be useful... ...Although we are finishing up engine #2 right now in the shop, as shown in this video.
Very nice boat! For those that think a turbo diesel might give it a run for the money they don't realize how much power a turbine makes per pound of engine weight which makes it a perfect boat powerplant. 1250hp from an engine that might not weight much more than just the turbos on a diesel. No recip will ever come close to turbine power.
That's a high capacity electric fuel pump being used here as a boost pump. It supplies a constant low pressure to the inlet of the on-engine fuel pump. In helicopters and aircraft, it would be inside the fuel tank and ensure the main fuel pump never has to suck or cavitate
Dude I subscribed and I just want to say I really love your videos and while there are other videos about engines yours is different because you act just like a fan and you know what is cool and show us exactly that and I think it is awesome.
After the race, I asked for the speed, and according to the on-board GPS they got to 143mph. But that was not necessarily where I was filming them. We're trying to get a bit more speed...
The noise is the fuel boost pump. explained below. Turbine engines do not have good fuel efficiency at low power, unlike piston engines. At max power, however, a gas turbine engine will consume the same amount of fuel as a piston engine of the same power output.
Awesome boat . I’m sure a lot of guys are running what’s in there budget with the piston boats . If they all had the jet set up it wld be a havoc of a race .
The camera is a POV HD, which markets itself as a professional-grade mini camera. It seems to be much more sensitive to vibration then a GoPro... and it costs twice as much.
The piston boats would hope for a breakdown in a turbine boat. The V8s are more familiar and easily maintained, so this was reasonable as their reliability was superior. I am new to this sport, and my job, as a professional turbine engine tech, is to increase the reliability of these surplus helicopter engines. In a way, this may destabilize the unlimited class, and increase the incentive to use a turbine. We shall see.
This issue came up in the comments for Pt.7: test run... we did some calculations, made some guesses, and compared this boat to a Bugatti Veyron...down about the middle of the comments list. Turbines are slightly less fuel efficient than a piston engine of equal power... but that only holds true when at full power. At partial settings, the piston engine is much, much more fuel efficient.
I don't think you can hear the gas generator. It's the PT that we hear going up and down, and it's going to be roughly proportional to the thrust... indicated by the rooster tail and boat speed. Throttle response of the GG is nearly instant.
This is like watching a six year-old kid, in Boy Scouts, who spent a few hours making his derby race car v. the kid who has his dad build his derby car and added lead shot in the nose and electric motors to each wheel.
I love the fact the start up is so predictable that your driver is happy to float with the current for a bit while spooling up..... and also the shots of the piston boats being left in a roosters tail! Awesome Stuff!
I never tire watching this. The accelleration must be incredible!
I have seen smoke puffs from big engines on test stands. Here I thought it was water spray mixing with hot exhaust gases. No problems were encountered.

Well it is the one that we've been following all through this series. Go back in time, and we get a good look inside it.
The awesome power of a turbine. I had to laugh out loud when the driver opened it up at the race start and the piston boats, while they had been in front for a few seconds, the whistle of the turbine overtook any and all challengers. Thanks - great vids

THIS IS THE BEST CHANNEL ON TH-cam
Thanks. Many millions disagree...
3rd best :p
I will say that it definitely does not suck.
I love how you rolled around like to show off then dusted them all. Great build! Kudos!
After surfing the comment section, you Sir, are a gentleman. Witnessing that boat run proves you are a scholar.
Thanks for the kind words. I had never been to NZ before, and I found it to be very much to my liking!
Still one of the sickest videos on youtube. I've watched this like 15 times now and has never gotten old.
No comparison to pistons
I've been told the engine has really good throttle response, and it looks to be on par with a piston V-8, only with more of everything.
@vinny142
26,000 for the gas generator; 18,500 for the power turbine, which then turns a 3:1 reduction gearbox
I used to fly LCACs in the Navy, that boat is very impressive. Brings back fond memories of extreme speeds over water.
Your guys were so far ahead they could have got out the paddles and paddled to victory. Very impressive, I love innovation like this. Good work sir.
"If you're gonna do something, you might as well go big". Well done boys,be safe and please keep the excellent sound capture's coming.
There is a severe amount of awesome in this one!
This is seriously one of the coolest videos on tube. I’ve watched it countless times. Amazing. I want one
Flipping awesome. I remember when I was a little kid all the big hydrofoils used huge piston aircraft engines, then the United Van Lines and Miss Budweiser showed up with their turbines and that was all she wrote. And so quiet.
…we FINALLY see the end result of your work! Most engines you build go in a can and disappear! This is OUTSTANDING!
Best jet boat video I've seen. That view off the back of the boat is just cataclysmic.
I can NOT get over how fast that is traveling. And what a view! Watching objects disappear in a fraction of a second as it flies by. My hat is off to the drivers/pilots. Oh, and of course the sound of that turbine is sweet. Thanks, Agent J Zed, truly a remarkable boat or as "Quint" would say, "vessel".
Seeing "JET CITY TURBINES" blazed on the side gave me a big 'ole grin 😁
Oh...My...God... !!!
This is absolutely amazing !
Nice build. Worked with TF34, T56, TF100, and P&W R2800 (radial) power plants myself. At least in the aviation field.
I hope the #2 bearing was tight, spinning them like that can foul up a lab seal quick.
Love the boat and the turbine sounds really happy.
The finish reminds me of the Indiana Gov.'s cup a few years back when I saw Miss Bud vying with Miss Madison.
Unfortunately for Bernie, Miss Madison was in the lead. Some of my most cherished clips. Audio sucked on them because some rotary death trap was hovering directly overhead. I was really proud for Madison In. when their boat finally won against big money sponsorship. To my knowledge the only Unlimited owned by a city.
Thanks. Funny, I live in Indy, where Allison (Rolls Royce) calls home! They have made gas turbine engines there for years, as well as transmissions. The M1A1 tank is Allison G.T. powered, as far as I know. I have many more comments & questions on your many great videos but I won't wear you out this time! Thank you very much & regards!
Darren
I'm seriously envious of all the fun you have with turbine engines. Lucky B*stard.
That's why they call it UNLIMITED CLASS, Run what ya brung and hope ya brung enough!!! lol
Love the turbine on the river racing boat! Great job on the build AgentJayZ!
I can't help laughing like a madman every time I watch this. SPEED!
That thing is such plain gettin it!! Nice work man!!
Jay Z awesome boat sir. iv never seen a jet boat perform like this. Awesome job.

A T58-16 with its 2 stage Power Turbine would give you a 500+ horsepower boost! I really enjoy your videos. Thank you, please keep them coming.
Everybody knows that, and wants one. Hard to find.
Wow 143 mph is very very impressive! Thank you for your response!
OMG, that was every superlative I can think of. Totally outgunned the opposition and all class. That was a truly beautiful drive in a very spectacular machine. A little shaky?, nah that's horsepower trying not to be tamed. Nice engine JayZ, looks like to be competitive they all need to visit Jet City?
This is awesome, I worked on T-58 engines in the Marine Corps, glad to see they are being used for racing.
You should watch the whole series, and tell me all the things I do wrong. Always good to hear from people with experience on these military engines.
WOW that was awesome! I love your vids.
Thanks for showing us. 120-130 mph on a river is amazing but fun only (although I am a piston guy). I didn't see a turbine on a boat ever and couldn't get the grin off my face for at least 15 minutes :-)
New subscriber here, also for the technical vids. Much appreciated. Regards from Germany
Nothing like the sound of a screaming V8, but--HOLY CRAP !!!!! I'm impressed.
Thanks for sharing a great video! Worth watching. Thank you! 👍
All I can say is ,,,,DAYUM!!! They were haulin ass!! That's pretty amazing!
The sound of that beast is incredible! Give him a few more laps and he will lap them all!
Lots of people posting their “brroooo boooosssttttttt turrrbbboooo speeeed” boats... nothing compares to this. You have dominated everyone.
Recently, a timed out ( meaning in need of a full overhaul ) T58 sold for 400,000 CDN. To restore that to aviation servicability would be another 2 or 3 hundred grand in parts.

Imagine a nice calm day fishing and then this monster roars past...that's how UFO stories begin!
Was watching the Allison rebuild and found this also. Very cool!
Oddly enough I would really enjoy cleaning and balancing blades all day for a living. As long as the tunes on the radio rocked!
Unlimited class of jetboat river racing. I'm just the engine guy, and I'm still learning about the sport.
Can't argue with horsepower indeed. That was incredible.
You put me on the floor with " things are heating up! "
That was a pretty astounding performance margin! I'll bet the piston boats were pretty depressed when they found out what they were up against.
The Sikorsky S-61 I fly has two of these GE CT58-140's. Great vid!
What kind of badassery do we have here?? Awesome!!!
Only the baddest of asses grace the seats of these stripped down competition machines! You bet it's awesome.
Hey Jay! Awesome video! I want a gas turbine engine like the T-58, but only 1/2 that power to play with!! Thanks for the work you do & I watched the whole ad before the video!
The rear roost shots are so amazing. Would be cool to get a flip to the front view of the bow also. Love this kind of racing. You guys are incredible.
The video you want to see is my race footage from the World Championships in Grande Prairie.
There's a search bar on my channel page.
a new fan nice job super fast i really liked it keep up the good work .
Thanks for the upload, Jay. This is really good material.
This never gets old Jay watched som many times and where she grounds and get pulled out by the helicopter !! class content
That was in the video about the Dart River in NZ. That was a crazy day.
Wow. That is really something. I meet up with the owner of a steam museum just south of Palmerston North in New Zealand a few years ago. Talked about the steam turbine/generator used in the Golden bay cement works in Takaka that he now has.

Wow this is the coolest jet boat ever!!!
Holy shit, Jay. You guys walked away from those piston boats @8:10 like they were just standing there.
Lol! Makes you almost feel sorry for the guys in the piston boats... no chance!! Awesome boat guys, really awesome!
Holy crap that's a beast! The poor piston guys lol
They're too much competition even for the Allisons and Merlins from world war 2 fighter aircraft. But they put up a fight. That reminds me, I want to rewatch the President's Cup when Oh Boy! Oberto beat Miss Budweiser again, this time in a straight up match. Seems like a 10 - 15 second lead.
T58s turn 6,000 pound watercraft into 200 MPH rockets.
You river racers are maniacs. I dream of being a fellow maniac, one day. Thanks for the vid!
Tom D I don't think it's all that expensive to get into the FX class, and they do 90 MPH...
You are awesome man! Keep the cool videos coming.
A jet jet boat. What a beast. Love it!
There is no afterburner. There is a reduction geabox after the on-engine SDG, or speed decreaser gear... it has a separate oil supply and pump. Maybe you're seeing that.
What amazes me, is that the boat stays so controllable. Them drivers sure have skill with 1250 at their disposal.
The Gnome is essentially the same engine. The T-58 is a license-built copy of the RR Gnome.

Piston boats can't compete with that much power! Amazing!
Not true. WW2 aircraft engins like the Rolls Royce Griffon engines or Allison's 1710, are just as fast as the turbines.
Those engines are more powerful, but I think the comment referred to the automotive piston engines that are allowed to race in this class.
Okay, I didn't know that. But that's odd, because the turbines don't come from automotive either ;)
That is a good argument for separate classes.
Yeah.
Dude I subscribed and I just want to say I really love your videos and while there are other videos about engines yours is different because you act just like a fan and you know what is cool and show us exactly that and I think it is awesome.

We're trying to get a bit more speed...
Vibrations - this is a great topic. Great Job!!!!!!
The noise is the fuel boost pump. explained below.
Turbine engines do not have good fuel efficiency at low power, unlike piston engines.
At max power, however, a gas turbine engine will consume the same amount of fuel as a piston engine of the same power output.
What else to go fishing?
You guys are crazy, I love it!
Another great video, cheers Jay!
Awesome boat . I’m sure a lot of guys are running what’s in there budget with the piston boats . If they all had the jet set up it wld be a havoc of a race .
What a speed! almost g4(lol)! super ! thanks for movie !
The camera is a POV HD, which markets itself as a professional-grade mini camera. It seems to be much more sensitive to vibration then a GoPro... and it costs twice as much.
The sound is awesome.
I love the small of jet 'A' in the morning

hoy la vi correr en tenosique tabasco mexico desde un principio en primer lugar una gran lancha saludos
And, yes, those piston boats sound awesome.
The real race is for second place!
I lovw this boat and the engine great job
This is like watching a six year-old kid, in Boy Scouts, who spent a few hours making his derby race car v. the kid who has his dad build his derby car and added lead shot in the nose and electric motors to each wheel.
This things freaking nuts. Look how much top end it has over the other boats. Took them to gapplebees after you hosed them off.
It get's real interesting when several turbine powered boats are running close together.
Not much water gets into the intake. The odd bit of mist and spray just makes the engine happier.
