Imagine! 1200 HP 260 CI TT LS Full Throttle/Full Load 5 Min Dynos! NRE's Tom Nelson explains.

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.

I’ll bet the race rules change after this season

Nre doesn’t make stuff to make money. They make stuff to be the best. That is some ingenuity.

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!

Made an old motor builder get chills

Ahhh water cooled headers explains the lack of glow :-)

[hotrod]

I have watched hundreds if not thousands of dyno pulls...this one is truly impressive.

[WarpedYT]

The bouncing off the rev limiter makes me nervous!!!!.

[alexandernerito]

The quality of the video is insane and so is that engine setup

[ldtenenoff]

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

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 😀

[Cronus_]

I've been watching your Dyno pulls for quite some time, but this may be the coolest thing I've ever seen.

[scottwalsh]

Bet that was the longest 5 minutes of your life!

[donmathias]

Has to be the best dyno video I've ever seen. A true torture test for an amazing engine.

[Sir.VicsMasher]

Great video. It would be cool to hear more about those water cooled headers. Whats next an aviation spec mirror image LS?

[Backyardmech]

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.

[terranceroybal]

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!

[Chuffin_ell]

Love the sound of a high revving de-stroker...

[bicylindrico]

Been watching Nelson for so long he is starting to look like an old man like myself

[captaincouldverc]

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
