- Have you ever seen a 1200 HP 260 ci LS engine full throttle and full load run for 5 minutes? I think not! Would you repeat again for a total of 12 Runs? Well that's what Tom's customer required of his new design of boat engines! This is a totally new engine design for NRE. A future video will describe this engine's unique build. Stay tuned to the NRE channel.

This should be the engine builder challenge. Can your 1000 hp engine run wide open for 5 minutes.
Likely 800hp at wot. Said the scramble button was to pass people
The gauge towards the end of the run said 764hp when he was holding 7k rpm. So this was most likely on the lowest setting
@Steven Ross-watt Agreed. A 5-min wide open test is kind of useless for most racing (except apparently boat racing, which makes sense). I would not be surprised if IMSA racecar engines would fail this test, and they are some of the more reliable race engines (because of the duration of IMSA races I reckon).
There's a lot of endurance engine builders that dyno at those levels for hours. If you're doing stuff like Baja, NASCAR, or Offshore Endurance, you really will be running WOT for minutes (or hours) at a time, for a whole day, and then again the next week. Then again, those engines are way bigger than 260ci.
EJ owners: hold my bearings.
I’ll bet the race rules change after this season
The trick is to pace yourself and win the season, but only by a little bit! If you go out and win your first race by a huge margin you're gunna have a bad time with the rule book.
jason beaulieu that's exactly what I thought.
I thought that as soon as Nelson said that there was a "small clause" if you're under 260 inches. That clause will magically disappear...maybe before next season
Yep
Ya but this season he will be king
Seeing all the other engines combinations you have built I was confident this one would pass the five minute test. Boat engines take a beating especially in rough water where the prop loads and unloads when the boat grabs air. I think the boat this engine will go in will be a force to recon with. Nice work!
Not only that, boat V8’s typically spend most of their life above 3500rpm. Where as your truck cruises along at 1500rpm for most of its life.
Turbos in those jet-boats don't really work that well, it might be that all-or-nothing peaky power delivery...something...the jets typically work better with the positive displacement superchargers.
Made an old motor builder get chills

Nre doesn’t make stuff to make money. They make stuff to be the best. That is some ingenuity.
and then triples the cost for good measure
Ingenuity costs money
@@Drivewaybuilt cheap, fast and reliable now pick two because you can't have all 3. I know nre builds very reliable engines and you get what you pay for.
@@lovescamaros1 You can definitely have all three but the real question would then be how fast, how cheap and how reliable? for 30k that damn thing had better go 200 miles/hr for 150,000 miles and make me a freaking coffee --- although, if I hit the lotto I'd call NRE the next day and place an order
Ahhh water cooled headers explains the lack of glow :-)
Yeah! I don't know squat about boats, and was wondering about that.
What do you mean water cooled headers?
@@waynebollentin989 Literally the headers have water jackets in them. Make up for the lack of air flow inside the hull where the engines are usually stuffed.
@@ericb065 what part of the video do you see water jackets in those headers. The reason water cooled headers are used on some boats is for noise mostly and where heat is a problem like on a normal inboard motor setup. The header coming of the motor needs to be hot to spin the turbine within the turbo. I do not see anything on the heaters coming from the head on the motor to the turbo. Please time mark where you see these water jackets. Thanks
Didnt know there was such a thing ha
The bouncing off the rev limiter makes me nervous!!!!.
It was just surging on the dyno not the rev limiter. I have my own thoughts on why.
That is to similate how the engine would be ran in the boat, they go WOT from green and it just limiter bounce or just below so him doing that ensures that nothing lets go when it is actually in the water
Just sounds like a little waste gate surge
I have watched hundreds if not thousands of dyno pulls...this one is truly impressive.
The quality of the video is insane and so is that engine setup
By insane you mean insanely shit. FFS people.
@@Rajonas007 how is it shit
I've been watching your Dyno pulls for quite some time, but this may be the coolest thing I've ever seen.
1) I love the new video quality
2) been a fan of your work for years
3) your craftsmanship and knowledge is on point
4) I cant wait for you to build my dream car again!
The most audibly pleasing video ever created... Hands down! More of this gnarpull footage!
Bet that was the longest 5 minutes of your life!
They did 12 pulls.
I'm SURE it was!! 😬
Form meets perfection. True model of what perfecting your craft means. Congrats Brother on the build.
Has to be the best dyno video I've ever seen. A true torture test for an amazing engine.
NRE for the win! Most underrated engines by far. This dude builds some badass engines I'd give a nut and a kidney to have one built for my project
Most insane thing I've ever listened to or watched! Well done
Been watching Nelson for so long he is starting to look like an old man like myself
dude I had the same thought lol
That’s an insanely COOL engine setup! Pun intended! Amazing to see that the turbo housing is hot enough to ignite paper on contact, but those trick headers right before the turbo is cool to the touch!!! 👏🏻 well done sir!
Some people dream of lottery winnings funding, college for kids, house for relatives , helping out the poor, I dream about sneaking one of Nelson’s engines in My Dakota, and taking all my car buds out for a sunrise. I have liked your channel since the beginning and to see you still pushing the envelope , with technology and a smile to boot,m release more videos man , you have an audience ... keep the faith 😀
Wow..... "there was suppose to be a loud KAboom" Hell no it's an NRE engine. Great Job and Well done.
I was just thinking the other day when you were gonna post a new video then you upload this gem. Thank you! That was music to my ears. I’d like to watch/listen to an uncut version of the engine just revving out on the dyno flat out
Absolutely amazing. Coolest videos I've watched in a while. Great job.
That is absolutely incredible. I would love to pump my LS3 up a fraction of this to see what it would be like. Awesome video!
Man I really would love to see an update on this engine. I know alot of things have been put on hold recently, but I'd like to hold faith, this guy was finishing up regardless of lockdowns
That is a testament of how good you are , right there. Wow friggin amazing and just watching from here was nerve wracking
so is that about the same cubic inches as 4.3 liter v-6 in my s-10? holy shit once again u prove u r the man tom wow love the sound what a thing of beauty. i think my first v-8 was a 265 in one of my 57 chevy unbelievable WTF i am smiling
WOW!!!!..Iam IMPRESSED!!!!😁😎 that sounds like a screamer!!!!! Nice work Tom thanks for sharing!!👍👍👍
WOW! Kick-Ass! I think I just found the new way to light my bong man! You Rock..as usual!
Another genius idea...Need to start NRE Shop Tours as ND start doing this shit!
I've always been impressed with this channel.
Thanks for the mention Tom!!!
Love the sound of a high revving de-stroker...
7.5k rpm is a disappointment in comparison to 20k rpm
czcams.com/video/ZOJkl4Agf4c/video.html
GEO000 Nelson is a damn good builder, but to be fair...I wonder how much his engine will cost versus a factory Honda F1?
@@Rajonas007 Rpm means very little, deisel engines rev extremely low and make a TON more torque and are capable of creating a lot more power with less cylinders. Some modified Cummins (6 cylinders) make nearly 4000 lb ft of torque with 1500+ horsepower.
@@Rajonas007 well yeah, but that Honda engine was something like 2 liter and 10 cylinders. Bit of a different design, no? Besides, rpm was not the goal here. There's 10k LS based builds out there.
@@Chuffin_ell There's also a v18 cylinder Cummins train engine which makes 178,000 lb ft of torque which only revs to 1500 rpm.
Damn that engine was banging that rev limiter! Cool to see an engine of that size make that much power and live on like nothing happened. A true bullet proof build.
It wasn't the Rev limiter it was the Dyno braking the motor to achieve a prescribed rpm
Love the plywood scatter protection. Also love the run we run are boats almost pinned all day
Wow thats impressive and sounded amazing. It even sounded like an engine in the boat with the RPM's jumping like it does when the boat is skipping along.
awesome work NRE people who know how ta build an engine.
The best way to test a motor with proper precautions, who said walls don't work when you may have a catastrophic event during a massive dyno run in case parts start flying all over. Now thats when know that your motor is absolutely fantastic. Great work!
This is a true full send. Love it. 💯
I could listen to this guy talk all day!👍
It has been over a year since I have watched a video from these guys and I still don’t have an NRE V8 for my Porsche 914. But I fixed that - clicked subscribe to see videos more often lol
You build a QUALITY product for FACT. Awesome to see this video as I know engines fairly well too. DAMN!!😁🤘
great work, lots of engines can flash big HP numbers but this one is for real and usable !
That had me on the edge of my seat, bravo fellas!
That was badass and legit... awesome build sir!
Pure insanity as usual...I love it!!!
That engine sounds sick. Nelson is the man !!!
Incredible video and excellent work!
I think u mean incredible work and excellent video lol
Engines like damn you, i want to rev beyond this stupid limiter! Nice work NRE as usual.
I thought the idea of turbo exhausts were to keep the exhaust gas as hot as possible before entering the turbo for efficiency reasons (high temp = energy/high gas flow speed). Why water cool the exhaust manifolds? Love to know the reason, these guys obviously know what they're doing.
The exhaust would melt off
You and your team have it down pat, and make some amazing designs and power
That was incredible. You guys build good shit. Been a fan since you guys built the F-Bomb for Freiburger.
I'd say one of the best engine builders on the planet!
NICE hey Tom, the twin 72s you sold me are goin on a destroked 6.0 so this video got me up and motivated. the truck is my daily so I haven't been able to install the kit I built but all the details are workrd out I'll send you the pics like I promised
That is F$$king insane!!!!! I caught the title and knew it had to be you!
Good job guys, that thing is a work of art 🤘
Awesome. You could hear it settle down and get into a rhythm. Great stuff indeed.
I'm glad to see content
Good job !!
This is how to push it to its limits,
It held up , now if you could do a video of complete tear down and show the world what the inside looks like after that never ending pull. This would be interesting. Cheers Nelson racing!
Production value gone through the roof. Sick.
Great video. It would be cool to hear more about those water cooled headers. Whats next an aviation spec mirror image LS?
TurboDieselDan pre heats engine cooling water.
Water cooled headers, or as I''ve heard them called before "water pack mufflers", have been on fast boats since the beginning of time. It should be easy to find lots of info out there if you'd like to know more.
@@TheBrokenLife Yes I know about water cooled cast iron boat manifolds. I'm interested in learning more about these double walled water cooled round tube turbo headers. Such as- is there a reason why they didn't use a billet collector?
@@Sir.VicsMasher Gotcha.
TurboDieselDan Its funny you say that, there is a company who makes LS based motors for aviation experimental aircraft. I saw a prototype at Reno Air Races 3 years ago. They were still waiting for FAA approval.
I would love to be in that boat screening up a river flat out, sounds awesome 😊
I've never seen anything like it! That was awesome!
Get it man best engine builders out there!!!
That deserves double thumbs up,sweet music
badass as always.. dude your are living the dream !
Great video ! Awesome motor and power
Absolutely amazing. Beautiful machine built like Picasso paintings
This is a true test of a builders ability with an engine. I would imagine heat dissipation had alot to do with getting this done
1:31 Radical clamps and a great guy that makes them.
I love all your videos and have been watching since the RX7.
Hopefully you will consider playing with VW engines one day. Lol
Maybe.
So sick! Killer job!
I remember watching his stuff like 10+ years ago it was insane then and only got better!
I hadn't realized you've begun using your own branded Turbochargers. Nice! #NelsonRacingEngines
Sweet video y'all have the best of the best
That was I think around 2004 when me and my best friend ran across a video of a crazy blue rx7 with a twin turbo 426 I think. I've been a fan of NRE since that day.
Water cooled headers ftw!!! I was wondering why they weren't glowing red after the first 10 seconds let alone 5 min. That's awesome!!! Beautiful machine!!!
I remember I first time I saw a Nelson engine. It was a 632 like 15-16 years ago. Been a huge fan ever since. I build high hp drag motors and Diesel engines but I’d love to build shit that crazy.
Whoever your editor is he did a great job.
Nice! I love a good long hold the power dyno pull.
Damnit I am inspired by everything you do!
Can you imagine having a job where you get to laugh in amazement at your own work on a regular basis? So cool!
Wow quit surprising. I was expecting it to blow any minute. It sounded like that. That's a good engine.
Good Work Tom
That is insane those headers staying cool is crazy
That’s awesome the true fact of a dyno is to put it to the limit!! Hate the flash high horsepower dyno pulls bullshit you put it on there to see if it breaks!! Awesome videos and knowledge thank you 🙏
A true test of the builder 🙌🏿👏🏿🙌🏿👏🏿🙌🏿👏🏿🙌🏿👏🏿
I saw a documentary where Burgatti runs their new chiron engine wide open at 1,500hp for 25 hours straight in dyno test.
TURBORYAN - I know, right? If VW can make those ridiculous lumps run at full power for extended periods - how is running an LS for only 5mins considered an achievement?
Full power /RPM running is the NORM for powerboat engines - routinely running for an hour or more, every time out. Time and time again.
That was the sketchyiest most awesome demonstration of a engine builder I've ever seen I dont think anyone else has ever done that . No one except mabe banks he is crazy as hell just to try it.
Well done, man👍👍😎
That had to be crazy nerve racking. Damn.
I hear ya boys thanks for the eargasm.👍👍✌✌
Absolutely fucking INCREDIBLE the hair on my arms stood up when the motor started pulsating then it smoothed out like silk!!! That motor LOVED 7000 rpms!
Great engine build.
This cooling is insane I’ve seen twin turbo LS engines that their headers are glowing red by the end on the 1/4 mile 😂
These are watercooled headers.
Ruby
Wow you crazy sir but I love it. Nelson is the Best! Period....
If agree he's the best turbo LS engine builder out there. Hell her built that v16 LS for that Devel car that never got built. Steve Morris is another builder that's pretty much on Nelson's level. He's got some videos of engines he's built. But I'd like to see more builders try a challenge like this!
Butler performance makes some mean race engines too but I love the nre street builds. One of the best in the business
wheeln 24/7 Nelson did not build the v-16 for that make believe crap car.
alanjrkaminski I have multiple times and it’s built by Steve Morris so maybe you should be the one looking up the video. Yes, Steve runs Nelson’s mirror turbos but he is NOT the engine builder. Check your facts bud
@alanjrkaminski He was right. I got Nelson mixed up with Steve Morris who built that engine
that is an excellent built engine. 👍 you talk about leaning on it hard....WOW!
I can only wish I could have a Tom Nelson engine Combo. wow nice job
Your not the only 1
I m not impressed that the engine last, i m impressed that the dyno can take all that abuse
Andrea Sanai yea I was thinking that but it is Nelson racing engines so a 800 to 1200 hp engine is pretty low compared to some of the other insane engine builds of his he would have a pretty kickass dyno I bet 🤙
@@carnation7988 yep he dynos 5000hp engines doubt this hurt it even over this long of a test with only 800hp
A dyno could just be a big propeller in a tank of water to create resistance, the water would heat up slowly soaking the energy from the prop shaft. Torque and RPM is all that is needed to get a power measurement
@@idgaf5252 You have to have some means of measuring reactionary force. If it was a prop how would you measure torque? Since the work done to the fluid would be quite hard to quantify unless you measured load in the driveshaft.
That said the prop would also need to change load to allow you to hold the engine at a given speed which is a pretty useful function of an engine dyno.
The hydraulic absorber accomplishes all that with minimal fuss and thus the reason most engine dynos are made this way.
@@carltonbankz9273 Not as simple as it sounds a 13 second sweep requires high peak flow. A long duration test needs thermal capacity. 1200hp would raise 400 gallons of water to about 150f in 7 minutes. I'm making some guesses here. Tom without a doubt has series large absorbers to handle that power for sweep tests.
LS power for the Win !!! That's a REAL engineered build !!
I can't believe how much my heart rate increased by just watching this...can't imagine driving the vehicle it's going into...my goodness..
That was awesome and kind of nerve racking.
