Please don't forget to update us on how this engine performed in its actual race.
Whys everything gotta be about race? Hahaha
Houston binkley Theres alot more playing into it in a actual race. Load variates during the race which can change the way the engine acts.. Also oil gets slung, air quality deteriorates, heats different, all sorts of things
@@houstonbinkley1844 because real world situation
@@houstonbinkley1844 I think your comment went right over these fellas heads. ;) i caught your drift and thought it was pretty good. 😁
Stanton Taylor I don’t understand
Big block rods on an lsx block. Piano string grooves around the cylinder. Tom ur a mad scientist, best of the best Sir!!!
this has been a thing for a long time
You used to be able to buy BB Chevy Rods to fit the old SB Chevy, it was a catalog item many years ago.
Many many yrs ago m8
New update my brother is on life support from a massive stroke please help pray for Shawn in Washington State
O-ringing is not a new thing, it's been used for many years in drag racing circles
@@johnparrish9215 Sounds Like P.A.W. Performance Automotive Warehouse.
Yeah, they're no longer in business.
I appreciate your knowledge and willingness to share the information!! Spec on spec. Way to go Tom!!
Yes he does. Tom truly takes engineering to a whole new level. He Builds some bitching masterpieces!💪
@@naterockwell7735 And yet here we are. Nothing comes out of his shop, and none of all his grand ideas ever came to fruition. Yep, he did the Turbonetics knock-off mirror turbos, and that was it. Meanwhile, Morris and several others are winning races, coming out with new ideas, new products and what not. Tom always talked a lot and made bold claims. But as they say, empty cans rattle the most...
@@AB-80XUh, ok..... 🤨
As a machinist I got really excited and inspired by this video. I've been a car enthusiast my whole life and a machinist for 15 years. This is some seriously cool designing.
Tom I miss your videos. As an engineer myself, I love the engineering shown with your builds. I also love your lingo, bitchin, cherry, etc.
Over the years...I’ve watched every single video Tom has produced.
I feel his creations are unique in that though they’re ultimately designed to produce stupid power. His special brand of form follows function philosophy produces truly show quality results...inside and out !!
The guys in street outlaws drag racing run 3500 hp easy.
@@cherb23 NRE is a has-been. Plenty of others do what he does and do it better. NRE was not first, and nor are they winning any races anywhere. And as far as power goes, when was the last time you saw an NRE engine produce the claimed numbers? There's a ton of him dynoing twin turbo motors, and yet they always fall way short of what he claims in the title. Tom always bragged a lot and talked a big game, but like they say, empty cans rattle the most. Today SME made 3080 hp on a 427 on 38 lbs. of boost. Tom seem to struggle to get a 632 to make 2200 on 32 lbs. Moran, Noonan, Goodwin, Morris, Reher-Morrison, Shafiroff and others are running circles around NRE.
This is the good stuff! Barely anybody goes to this level and then documents it like this. This is why I have been watching NRE for so many years.
Thanks for recording and showing us this awesome content Tom! Keep us updatet. 👌👍
"Very Professionally Presented" thank you for sharing your knowledge. I am in hopes that this project begins you hundreds of new customers.
Mad Respect
Thanks for caring about us and thanks again guys for the great video upload
I've been around cars most of my life and this right here hits on everything I've always been drawn too. Incredible craftsmanship, technology, engineering, all resulting in incredible results. Thanks for sharing and PLEASE do more like this. I could watch this stuff ALL DAY
Congrats Tom and crew at NRE, that's really showing skills and proving them too! I'm very impressed
Wow! Just one beautiful design! Sweet! Thanks so much for such an awesome video! Have a most great day!
You are by far the best engine builder out there today. Listening to you talk you are a real person.
That's very impressive. Nice work NRE. Been watching and enjoying your stuff for many years.
Very informative video, it's always interesting to see a good video on the inner workings on a high performance engine build.
14:05 watching that plastic creep in on the bottom left hand corner gave me anxiety. "oh no - don't you do it....."
Can you imagine the damage that thing could've done
Going back and paying attention now, yeah I feel ya on the anxiety.
tony zooks Agreed. That would've been a costly mistake.
Yeah them turbos are like feed me. The plastic bottle is like ok omw.. Lol
Looked like an aerosol can fell off a shelf...
Tom,
You are a true inspiration to me! My dad was a motorhead and owned a Mopar dealership back in the late 60s early 70s. Passed his love of muscle cars along to me. I remember buying small 12V electric fans, fabricating a new intake, and installing my new "superchargers" on my 2-stroke dirtbike at age 10. I would mess with the jets, fuel mixture, ALL DAY LONG! I swear it made more horsepower than stock :) I can smell the Turbo Blue now. I love your enthusiasm and extreme level of knowledge. Of all the so-called "big name" builders, there are several points in your video I've never heard ANYONE else mention. Best of all, everything you say is backed up by rigorous testing, and REAL WORLD horsepower numbers, NOT marketing HYPE! Thanks for keeping it real Tom and being a great example of a true American!
I could listen to that motor all day, who else listen to this motor sing for the last 5 min?
Thank you so much for these videos I know you dont have to do these and especially not these in depth technical videos. It really helps me being a younger guy get the full picture and understand.
Unimaginable knowledge. Truly one of the best engine builders.
Jet boats are hell on motors. I grew up with them and it killed my dad to see me swap to outboard boats. Mainly cause i wanted to run 100 for miles instead of feet. You have worked some magic to run a boosted motor that hard. Lots of guys in that class run turbine motors to handle those long runs. Yall have got this stuff dialed in for sure.
Michael Teeple he's not the first to run a boosted motor. People have ran twin 500 plus cubic inches with blowers for a longtime now
@jonny j he was saying boosted inboards are not reliable, off shore racing proves they are🤷. I like outboards too now. My dad had a 225 Johnson on a little 18ft laser bass boat with tunnel hull under it. The only thing in the water was the foot and sometimes that back of boat a little. It would run well over a 100 never had it clocked in but he raced Allison craft with a 300 v8 Mercury outboard and beat him bad. He would start out from mill Creek on lake Marion and run to I95 bridge and back total of twelve miles. He would start out with a full 46 gallon tank and be on fumes when he got back. He literally never lost a race with that boat. Although he never raced in any professional races🤔 just long distance straight top speed runs. You could see him all the way to the bridge with rooster tail you could only stop hearing him about a mile from the i95 bridge which is right at six miles from mill creek
Impressive as usual Tom. Glad to see you look good following your accident a while back. Glad to see you back in form and building fantastic engines.
I want to start a savings account just so I can come attend your tuner school someday! Love the videos Tom. Always appreciate how much info you share with us.
As usual another first from Tom Nelson you are truly inspiring always pushing the envelope in developing new technology in engineering .a true engine artist hats off to you brother no one builds a more badass engine than Tom Nelson.
That is pretty hardcore. Love that oil pan design also. Very nicely thought out.
Awesome camera angle and sound recording this engine has a magnificent sound, thanks for sharing buddy much appreciated.
Damn Tom, you got a water truck outside feeding the Dyno?
I was thinking the same thing!🤣
adrenaholic1 Yep, and a city water main for the cooling system.
It's a boat engine. Has an entire water body for heat exchanging if need be!
@@N4CR5 over your head eh?
@@TheRamGuy He is too fast, nothing flies over his head. He will catch it ;D
I love you giving us mechanical specifics and ideas. That was 5 minutes of cool.
Absolutely: Nothing Short of Brilliant...!!! The Nelson Race Team are the MEN...!!!
Strong individual. And gracious enough to share his wisdom. Thanks man.
This little motor is a beast!
Forget the bottle cap challenge.
Nelson 5 minute dyno challenge!
You guys did an AMAZING job reinforcing a good little engine. I am impressed.
Thank you for this awesome video! Absolute great work, you guys are insane! 👍👍👍
Very cool to see Tom and never disappointed with to put your hands on
Bitchin! Awesome for you to share all the little details, very interesting! Proof you over-engineer and put a lot of thought into your work. Right on brother!
You put a lot of tought and planning into this engine build. I look forward to updates.
Great piece of engineering!! Wonderful that you share this build with us!!
More more more Tom .. we need more Like this .... love your work, this is truly art
Wow, rare to hear one of greats talk about the internal details. RESPECT!
Tom i have to leave a coment this time,,,,that 261 is beyond tricked out,,,it is just awesome,,,and that mid engine car to,,,you are the #1 master guru of engine building in the world,,,kudos to you Tom,,,thanks for sharing those awesome videos and stay safe,,,,Ken
Tom: I subbed to your chan a *heck* of a long time ago, 'cause you were building some killer stuff & [[[occasionally]]] 'stickin' it to da man', lol. I'm so glad you're putting up some new stuff! Admittedly, a *_260 c.i._* LS was NOT what I had in mind, but I'm absolutely *_floored_* by your results with this project! It's also very "Nelson-esque"...
Really like how you open you are. I don't think top engine builders are gaining any clients by keeping their secret spec cards so close to their chest. Like someone could easily do all that stuff in their garage anyway. I really appreciate you democratizing cool info. Way to go Tom you're cool as hell.
I like that you're sharing the technology. I don't need it for my application, but it might inspire me to design something similar for what I'm doing.
Toy are the Master! I am so impressed with your details and finished engine tech!
Respect for sharing your knowledge! You're a true pioneer.
I think it's really cool that you are sharing some of your secrets to success. A lot of good ideas from a pretty smart fellow!
I have massive mechanical sympathy and I'm a mechanic and worked on engines for 30 years so I know what engines go thru when they run hard . seeing the parts he put in this engine I have no problem watching this one scream for 10 minutes it will eat it up. like they say let her eat
Yup I'm convinced everyone would get tired and go to sleep before that engine would let go. Have to test it in shifts 😂🤣😂
I agree but so far i dont know the cam bearing he used
@@D3AThCAl2DS He didn't say much about the cam, or I missed it.
You are truly the best, your performance, looks with the mirror turbos. Just freaking awesome.
The amount of dedication NRE shows surprises me every time.
No doubt about Tom Nelson! What a great engine builder and just a down to earth nice guy!
Absolutely awesome engine builder. Fully functional works of art.
Man you guys are killin it man. Awsome. I bet you have people beating down your door tying to work for you. Killer killer stuff
There's a lot of external load forces being applied to every component of a race boat motor. Take into consideration the slamming the boat gets every time it hits a wave, that transfers into the engine components also, or an over rev condition when the prop comes out of the water. Not like a smooth black top surface. This engine is a masterpiece. Keep us updated as to how it faired out in compitition.
Man. De-stroked main and rod overlap on that crank is insane strong and stable. Mad scientist at work again. 😎😳😳
Excellent Video , Love to learn ! , Tom is the Master Instructor , Thanks Tom !
Your a God Mr Nelson. I bow to your engine building skill set.
Balsphemy ...
He's nowhere near a god. Better builders than him. Boat engines that run for long periods on dynos? Eddie Young, Tommy over @ Chief, Randy @ Cobra, or Sterling Performance, not to mention a slew of other guys have been doing it in offshore racing for years. Try running a 1600 hp blown 588 like this for over an hour and do the same in the open seas later on. Now that's a real test.
@@AB-80X yeah there's always someone better. And you can't deny that Mr Nelson has done shit with ls engines that others can't come close too. I was complimenting the mans skill set. I didn't say he's the best boat engine builder.
I totally agree
To watch videos of Nelson ripping down the road in one of his mirror image turbo creations, he seems like just really cool, badass, wrench turnin mechanic. Then he breaks it all down and you realize this dude is a certified geeked out Genius🙏
Thank you for the knowledge!!!!! Means a lot to guys like me that don't know ish'!
Tom idk if you will see my comment but i really love your videos man. even seen a few of ur engines in some LODRS drag racing on drag racer tv.
👏👏 I expect nothing less....How much to replicate this motor combo..just the motor.
I can’t believe how well you built your engines and how much attention to detail you put in them... definitely one if not the best engine builder out there right know... 👍🏻👍🏻👍🏻... i which I could have the means to buy and engine from you 🤷🏻♂️🤷🏻♂️🤷🏻♂️
Great job on this LS build. I think this engine will do well
watched that full dyno run twice speakers cranked. nearly midnight. bad luck neighbors
This build is straight up kicking goals. having the experience to see the things that hold the design back then engineer parts to overcome and push the boundaries puts you so far ahead its almost cheating. its a true credit to all of you involved. that health check is proof that its reliable and repeatable. watching this channel like a hawk
All I can say is that is one hell of test!!! Awesome job 👍
Thank you for all your knowledge and research
A friends dad (Mr, Daryl Buhel) was a winning Top Fuel engine builder from the beginning & was one of the first to run a all aftermarket engine (by Ed Donovan) ... I learned so much from him & he was spraying the under side of the pistons through rifle drilled connecting rods on a custom Aluminum BBC 540 twin turbo designed for aircraft.... I notice both of you have a "common sense" , no substitution for the proper material.. He smiled as so many in the industry "followed the other guy", and his saying was (NO FAIR THINKING). Doing things because "others do it" will get you where they are. The way you (NRE) approach the build should get you records, & wins if the rest of the build is up to par...
The 18 thumbs down are from the competition!
Would love to see that crank used in a NA application for a screamer engine
Wouldn't really work well n/a. That's why land speed racers and such just kill 2 cylinders and run on 6 instead of running such a small stroke. Doesn't make enough compression.
I know one thing, if I had the cash, you my friend would be the man I would hook up with. Engine God. Thanks for sharing.
Nelson I love your motors I wish I could afford one of your motors to put in my Malibu keep up the videos 👍👍👍👍
Maybe he'll see this comment and get you to hook up 😁
@@1BigDaDo You will get "hooked up" if you got 40-50k to spent. Plus these engines would destroy your stock malibu.
@@petesmith9475 there not all that much. he has them in the 14k range and up for twin turbo, NA engines iirc start around 8k
@@petesmith9475 try 150 to 200 my friend 40 to 50 might get you started
@@charlestorruella8591 wtf no. No one is paying 150-200k for an engine like this.. its a parts box motor and some machine work.
Bro, you guys have the best car channel on CZcams. Where are your current builds and vids? Miss you guys man.
Thanks for sharing Tom! That's some great insight
3 years since the last post. I see you guys pretty active on FB, but we sure would love some in depth content on CZcams!
It would be cool to see Tom Nelson and Gale Banks in a series of engine build videos together.
One of the most powerful, yet efficient engines to ever roll out of a shop.
i really just thought Tom was Gale's adopted son??? LOL!!!!
Tom and gale are very similar imo always striving for more hp and efficiency, better desighn
Don't forget Kenny duttweiler
@@danielsullivan9865 I mentioned Kenny to some young guys and they were like Kenny who. I normally don't stretch out a lead but I had to put a couple of bus lengths on them for laughing at my " stage 2 Buick". They assumed it was like how guys say they have a stage 2-3 setup these days and I heard them laughing saying how they'll smoke grandpas stage 2 setup from the 90's. I'm only 38 and they were punks with a pos LS turbo thinking they where fast so I didn't feel bad for taking their $1500 worth of lunch money for the year that the 4 of them put up lol. The best part was when they googled Kenny Duttweiler and stage 2 Buick they actually had the balls to try and get their money back because I had a true fully built race motor. If they weren't punks I might've given most of it back, but they needed some schooling ;-) Plus I showed and told them exactly what it was although they didn't notice the AWD ;-) But it's a Sonoma GT on a back halved Olds Bravada frame running a Frankenstein trans out of a Trailblazer SS behind the Stage 2 Buick that Kevin Banks originally built for a Busch series car and Kenny rebuilt and converted to EFI and turbo for me. It's crazy what a new ECU, injectors and tune has done for it though. I haven't changed anything else and the modern Haltec Elite 2500 and E85 has dropped over 2 seconds from my old best time.
Nothing can substitute YEARS of EXPERIENCE! That is one sweet mofo engine! When I'm building my project one day, you bet I come to you guys! Great work!
wow. just wow. I'm sure a specific machine shop mecca down south has taken note of this build.....Tom, you are a badass for sure. I have never seen anything like it, since I learned of the boss 302 heads welded together and mounted on a 300 CI inline 6 Ford. Which also, was WAY before my time.
As I said after seeing the first video on this combo, Damn Tom !!!!!! Well done. You and your team continue to impress. The engineering,WOW !! But alas, now we need some new bad ass street test videos. Please!!!
Too bad it's for a jet build. Doubt you'll see it on the street until if/when someone else orders one.
Yeah , don’t think this would be a good idea for the street anyway. This one is purely custom and small displacement. His 427 tt hot rod series is seriously bad ass and nearly perfect.
Thanks for an educational view into professional engine building interesting dry sump arrangement. 👍
Awesome video. Loved it!!
Definitely need to win the lottery. An NRE motor for my daily driver would be a dream come true.
Your builds are awesome brother
5 minute engine pulls. Awesome 👍💯
Love listening to you talk ls!
It's like going to school every time you show us stuff you do! I can't wait to see how this engine did after the race?
Need this channel back
man all I can say wow that is incredible. sounds awesome too
You have a amazing racing mind! Love your videos
It's been 3 yrs RIP to this channel 🎈🎈🎈🎈🎈
Amazing work as always! Would love to see NRE to some phnuematic valve train stuff!
Music to my ears! I was getting sleepy listening to it, its so soothing! Epic build. I was hoping you'd go into the header design, as i believe in the original clip it was mentioned they were water cooled, dual wall units?? Epic vid either way, this may break the net!!👌🤟🤟
Tom, you do some magical things with engines.
Extremely well illustrated..
now that is impressive. nice work
i spend 75% of my life around Inconel. I work at the company that invented it years ago. Inconel from International Nickel company. Inco now SMC owned my Berkshire now. Maybe Mr. Buffet will want to sponsor a good ole turbo ls and let me borrow some 751 lol
I'd like to see a you do this in a mod motor configuration, just cause you sir are an incredible engine builder.
I'm absolutely impressed!!!
I miss the old school NRE videos with those awesome test drives.
Hell yeah, i'm not a v8 fan, but this is how you build engines!!! I really liked the idea with the groove for the piano wire, don't know why not more companies would do that, the engine from Cleetus had problems with the gasket rings pushing out, so i thought why not make a groove in it?!? It sounds sexy as well! Looked alot like Leroys setup tho lol.
Keep it up!!👍👌
6 cylinder turbo diesel guys have been doing stainless O rings on performance builds for decades now. Its needed when pushing over 50psi of boost and gas engines have just now begun to run these boost levels vs the diesel aftermarket which has been doing it since the 90's
THE most badass engine builder!
Wow it delt with that long of a run .. The externals are just increditable. WOW Thanks for TIPS .Grand finally .
The dyno is such a great simulation of that engine being in a jet boat, thats basically how the jet pump in the boat acts/works just like an engine dyno. Requires x amount of horsepower to turn the jet pump at x RPM. Awesome build guys!!
