pannic11 1200 crank HP from a 260ci LS? No, it isn’t, IMHO. At all. It’s a 1000 rwhp turbo combo. I build 284ci Ford street engines that destroy this all of the time. I’m more impressed with the craftsmanship of his billet intake manifolds than anything, I’ve never seen a Nelson engine that impressed me on power output.
Taking some notes on Gas turbine engines lube systems even the lock wire. Love the engineering on that beast. The added thickness piston tops , huge pins and trick oil let’s for the bottom of the pistons . 100% great engineering!
Damn that’s painful to watch ,but excellent proof of concepts . I say concepts because of the innovations and quality of the parts and knowledge built into this engine . Gr8 job.
Reminds me of when i was a kid in the 70's. My dad had a friend that ran NHRA prostock and my dad helped him out from time to time. Back then, there were not a lot of go-fast catelog parts. You had to make everything. My dad and he were aircraftmachinists. As i recall, they ran a 327 small block stroked way down...i have no idea - 260 or 270 something ci. Concreted heads, o-ringed deck, rocker and crank stud girdles. Dry sump pump. This application was all about high RPM horsepower. Had to run a magneto for the high revs. He ran it through a race prepped powerglide and outback was some outlandishly low geared rear-end. One shift at the 1/8 mile mark and it was RPMs to the 1/4 mile mark. Not sure where the RPMs capped-out at but dad said it was in the high 4 digit numbers. I was a boy then so i don't have real numbers. What i do remember was the freaking huge tunnel ram and header pipes the size of tennis balls. They were moving some serious air. So old school.
Not to shabby, see a lot of the same techniques that I use on my builds on this engine. That was a hell of a torture test though. I've never used that kind of exhaust valve though I would be concerned about that friction weld not being bonded correctly and dropping the head of the valve in.
thats the whole purpose of having it on the engine dyno. To find the weak links BEFORE its running 90+ mph down the water and costing the owner thousands...
I love this guy he is a FUCKING MAD SCIENTIST!! I wish I had the coin to have Mr. Nelson build an engine for me. Someday Ill have the jack it takes and Ill be knocking on his door!!
@@brettgast Anything you do to a smaller displacement motor will be exponentially more-so in a larger displacement motor. It's simple science.

WOW! Can I borrow the motor this weekend?? Would ceramic coating the Pistons also keep it kooler on top too? The oil galley jets are they free floating or welded in some how... Also, I seen we're going with the lsx cast iron block. A great block..but what if on a aluminum block application? 🤔

At 1,200 hp What was the TORQUE, on that awesome 5 min pull. I'd love to have a engine designed to take that kind of torture. It's not abuse if it's ment to run under that kind of condition.

But the iron block coud'nt take the stress due to its design.
@@donaldkinder6716 Funny thing about that is ford goes through the trouble of putting a flat plane crank in and then proceeds to destroy the benefits by making the headers unequal length
@@donaldkinder6716 Is that why they needed the SB2 in NASCAR? their "real engine" the first gen small block and LS looked pretty weak when they asked to run a clean sheet competition specific race design against the Cleveland Ford designed in 1968. First non-OEM engine allowed and first time a manufacturer to ask for such an allowance.
None of these engines would live without Mike Laws' patented piston oil squirter. Patent is long expired but it was violated into oblivion. jack rousch was particularly fond of stealing patents like it, and selling them to ford. Those squirters, along with valve spring oilers helped senior beat Mark Martin for another Cup championship. Mike was the real innovator at Bo Laws Racing.
I realize in an application like this/ marine your gonna want to tune AFR to keep the EGT's under a certain number (looks like 1400 F). Im wondering what AFR it took to keep your EGT's under that number.
Why does it have water jacketed exhaust? Was the displacement chosen for rules purposes or to get a stronger crank and less piston side load? Thanks for sharing some of the build details!
Great build Tom. I like the recessed edge of the top of the cylinder. I was thinking, why not make a raised edge circles on the cylinder heads to fit in each recessed valley. Perhaps make the recessed valleys just a little to small & heat them up, & the raised lip circles to big & freeze them, when installing them. I also think it would be more powerful if you fired two pistons at once, like the front piston on one side & the back piston on the opposite side. I'm sure these billet cranks could handle the force easily. Another idea would be to turn a V8 block into a 4 piston block by making rectangle pistons out of two cylinders, & rectangle valves. The intake valve would be on the top side near the jntake manifold, & the exhaust valve on the bottom. The header could be rectangle shape at the top that turned into 2 inch round tubes. I also believe a flat plane crank is better balanced & produced more power & rpms. I was also wondering if you've ever heard of throttle exhaust. We use it in RC nitro boats & they work really well, perhaps it would work well in fuel injection turbocharged v8 engines. Keep up the good work, your a great engine builder.
Nelson is a local guy. He is sort of our Michael Jordan of engine builders. If you don’t know where his shop is just drive the streets of our city until you find his trademark mile long burnouts and you have arrived.

Almost none? The engine is still the same size. The pistons and pins are made more sturdy in their dimensions, so heavier. Crank is shorter, but rods are longer. Dry sump weights a little more than a pan would. Big Holley intake. This thing probably weighs more than your average lsx build.
Shelby Avant Wasn’t clear to me and since 454lsx doesn’t exist normally and he didn’t specify on 427 I was thinking maybe he was referring to the old BB... also the ls motors are basically the same their weight is so close.
Tom Nelson got your ears on ? I want to see a NRE small block Chevy configuration equiped cam, rods , pistons. crank , bearings etc. etc. set up of NRE choice set up to be compatible for todays modern two four barrel EFI throttle bodies which I just now watched a video from nitrous express express claiming you can program those bolt on EFI four barrel throttle bodies to spray more fuel for DRY NOS ....example of a EFI 4 barrel throttle body system www.edelbrock.com/shop/fuel-injection.html why you ask ..? these EFI bolt on plug and play self tuning 4 barrel throttle body kits are getting cheaper to buy ..allowing the average street racer to put more bucks into the build quality of the engine internals ...like this boat motor shoehorned in under the hood of a Chevy Chevette ... back in the mid 80s on south west archer avenue Chicago there was a speed shop specializing in selling turnkey pro street chevettes with 502 big blocks with a tunnel ram. rising out of the hood two holley dominators and those. huge full coverage vilocity stacks that look like spittoons level with the roof top of the car ..they were tub-bed out with mickey thompson's narrowed rear end so all you saw from the rear was big rubber a Dana 70 pumpkin and more big rubber anda short set of wheelie bars ...

@@sladesarosy7193 The people who commented would appreciate a joke if it made sense but they understand that small engines are run at a specified RPM with a governor...and knowing is half the battle, GI JOEEEEEEEE
would not applicable lol... it only makes the power it does due to rpm , which means that small of cubic inch it needs alot of love separation angle because you cannot stuff that much pressure in to a small cylinder at low rpm due to turbo pressure is low at low rpm, now add to that tire rotaional rpm to gear ratio to torque converter multiplication rate.... look at how much it cost just for a true tranny to handle that level of power constantly.... the oil squirt on piston underside is nothing knew at all... notice he used a thick height piston to absorb the heat generated from compressed pressure of boost,bhe used a big heavy rod because you need more weight to handle the high rpm, it's .5 longer than even the best ls sbc rod and probably 2xs heavier
you would need a very steep rear end gear to keep it in its proper band per the valvtrain event timing, and where the fuk you gonna be hitting 9k rpms in ever shift lol ahahaha...
Awesome job! However, that plastic bag on the floor of the dyno room bugged the heck outta me. Thankfully whatever was in it was heavy enough to keep it from flying through the air. All I could imagine was it getting sucked into one of the turbos! LOL
What I would like to see is this engine in one of those wind tunnel things where they test aerodynamics were they put smoke and see how this engines sucks in air.
Why won't ha thermal coat pistons crown and the skirts. If you layout big money for engine does make sense. 1200 hp ls twin turbo v8.here in Australia we have 242 ci 4 litre inline six road rego with 1200 plus hp at rear wheel.check out dynamite performance with there destroke 4 litre inline six to a 3.7 litre 2000 hp 10000 revs.you think small block making that power is unreal . Jet performance 4 cylinder making 3500hp that's unreal.
I understand how your cooling the piston from glowing red but at full boost why aren’t the headers glowing red like the rest of the race/street cars at full boost let alone for five minutes
In my opinion you can go to school and read a 1000 books but if you don't add pages to those books or invent something from the base knowledge that you gain from those books you're a thief. and you sir have given back with the knowledge that you have taken from books and experience you are a king a creator you have creativity flowing through your brain it's awesome keep up the good work intricate thinking good. meditate become more.

Very cool, would probably have trouble staying at full throttle max rpm for 5 min though
It has been done bunch of times, even with cheap ebay turbos. But they are dyno queens and won't last a race season.
That oil separator pump is something sweet. I even want one in my daily driver, let alone in my race motors !

@@TheCulnes I see u can also not take a joke and have no sense of humor
Nelsons (not so) secret is ripping customers off and supplying sub par equipment 'if' he delivers it.
I wish you could be the engine builder for all GM applications
Tom is a true Rock Star !
It’s guys like him that Tirelessly Work to advance innovation!!!
And why would anyone skip 5 minutes of WOT ? Damn son!!!
Boat racers
Ikr!! Delayed my shower to watch this.lol
Nelson should build the new C8 engine.
It would have to be an extremely limited run. Look at the Hellcat. Not many people can handle 500hp. Much less a Grand.
Next chief engineer.
@@SGTJDerek there's money in it man, who cares if they can't handle the power? They will figure it out
Sure is nice to see a true professional. Meticulous. God bless
Can you squeeze that into my Acura NSX, PLEEZ!!! 😉
What a very nice guy too, nice clear explanations. Smart guy.
Imagine this in a street car? 4.2L, no one would suspect that power. lol. I vote for a Miata Swap. 😂
Yeah engine still there Miata chassis looks like a pretzel 😂.
would not applicable lol... it only makes the power it does due to rpm , which means that small of cubic inch it needs alot of love separation angle because you cannot stuff that much pressure in to a small cylinder at low rpm due to turbo pressure is low at low rpm, now add to that tire rotaional rpm to gear ratio to torque converter multiplication rate.... look at how much it cost just for a true tranny to handle that level of power constantly....
the oil squirt on piston underside is nothing knew at all... notice he used a thick height piston to absorb the heat generated from compressed pressure of boost,bhe used a big heavy rod because you need more weight to handle the high rpm, it's .5 longer than even the best ls sbc rod and probably 2xs heavier
you would need a very steep rear end gear to keep it in its proper band per the valvtrain event timing, and where the fuk you gonna be hitting 9k rpms in ever shift lol ahahaha...

It was a real treat for me to see the MASTER at work. I certainly learned so much. THANK YOU.
5 min full throttle... not a cop in sight I think I can get out of it now
Awesome job!
However, that plastic bag on the floor of the dyno room bugged the heck outta me. Thankfully whatever was in it was heavy enough to keep it from flying through the air. All I could imagine was it getting sucked into one of the turbos! LOL
What I would like to see is this engine in one of those wind tunnel things where they test aerodynamics were they put smoke and see how this engines sucks in air.
Why won't ha thermal coat pistons crown and the skirts. If you layout big money for engine does make sense. 1200 hp ls twin turbo v8.here in Australia we have 242 ci 4 litre inline six road rego with 1200 plus hp at rear wheel.check out dynamite performance with there destroke 4 litre inline six to a 3.7 litre 2000 hp 10000 revs.you think small block making that power is unreal . Jet performance 4 cylinder making 3500hp that's unreal.
PURE GENIUS SIR...THAT LITTLE GIANT OTTER REALLY SPIN!!!!!!!(I had to add a water critter...)
394th 👍's up Tom thanks for taking the time for us
I understand how your cooling the piston from glowing red but at full boost why aren’t the headers glowing red like the rest of the race/street cars at full boost let alone for five minutes
What kind of fuel consumption??
WOT FOR FIVE MINUTES.
IMPRESSIVE!!
In my opinion you can go to school and read a 1000 books but if you don't add pages to those books or invent something from the base knowledge that you gain from those books you're a thief. and you sir have given back with the knowledge that you have taken from books and experience you are a king a creator you have creativity flowing through your brain it's awesome keep up the good work intricate thinking good. meditate become more.
With such a short stroke, what kind of torque does it make? Probably doesn’t need much considering it’s in a boat.
Boats need torque
All gold everything? NOPE
All billet everythang...
the old saying was, "there's no substitute for cubic inches" except when boosted to hell? Lol shit my little (250cid) 4Ltr quad cam quad valve v8 spins over 9600 on 30+psi an its real nice seeing someone else prove the point too
