- Crazy things tend to happen whenever we get together with Newcomer Racing on the engine dyno. And this video takes the cake! Originally, the plan was just to test this turbo setup with a ridiculous 11.8:1 compression ratio. But things got out of hand quickly. We blew things up, we make huge horsepower numbers and we even think we made history! Just watch and see.
If you are seeing Newcomer Racing's previous ultimate high-horsepower build, check it here: • Turbo Jeep Smashes Wor...
The Jeep 4.0 liter straight six is known as a reliable and torquey -- if low horsepower -- plodder. Engine builder Keith Newcomer shows these engines are capable of much more than anyone ever figured with his latest turbo build. Eventually, this engine will likely make its way into our drag-and-drive Rambler race car.

What an impressive outcome, Keith is really making us AMC people proud!
This! And there ain't many of us left either
@@Drmcclung here. :) putting together a little '68 gasser with an angry 360 right now. (And probably for the next few years, lol)
@@naturalcreature6317 i don't know that I'd want to listen to one of these spin at 10k for any length of time in a road application 🤣 big straight 6 harmonics are just not nice! At some point even a jz starts sounding like a vacuum cleaner
@@Drmcclung
Inline 6 harmonics are usually somewhere between 6 and 7 grand. Depends on stroke, bore centers, materials etc. One the AMXJ channel there are a series of interviews with a former Jeep drivetrain engineer who was involved in cylinder head design. He was also involved in a 4.0 powered dragster that set class records. The engine was spinning 9K plus through the traps.
@@mpetersen6 Yep, for all engine configurations there are two stable harmonic ranges (well technically more, but how the hell do you reach the 3rd+ stable range). The issue is transitioning through the destructive harmonics in the 6.5-8K band. Once past that, presuming your other components are up to the challenge, you won't have crank destroying harmonic problems again till well past 11K.
This blew my mind. Im shooting to get 300 outta mine, but 1000+ tickled me pink. Mr. Newcomer you are an inspiration to everyone and so many more 4.0 enthusiasts like myself.
1,082 horsepower from a stock block 4.6L is insane. That Rambler is going to be a force to be reckoned with. Can't wait to see the Rambler complete and racing.
OUTSTANDING!! I never thought 1000+ hp was possible on a 4.0 block. Keith really knows his trade. I'm impressed 👏👏👏
Great video!!
I love these videos. Almost 1100 horsepower is awesome. I knew it was gonna be good, but this exceeded my expectations. Great work, everyone.
That’s a spicy 4 liter 12 valve meatball 👍
Ha! Correct!
It's real simple. 🙄 Duh
Some engines really get my motor running; But I wasn't prepared to make it all the way to boner town on one tank when this "crappy little AMC-6 from the Victorian age" started printing her digits! Us AMC guys don't get a whole lot of love even on a good day, but this was amazing and I can't wait to see this receit printer dropped in the Rambler! Sidenote you should call it the "Rambler 500"
Keith keeps people like me in love with their straight six
Ancient push rod straight 6? Check! Cast crank? Check! Carburetor and distributor? Check! 1000+ horsepower? You betcha. Freaking awesome
This channel has consistently great content. Thank you so much for bringing this to us.
BTW- it takes more power to run the turbo into atmosphere than it does when hooked to the intake.
It was the wastegate that blew off, not the blow off valve
How would a turbo spinning without compressor restriction use more power than if it was blowing into the intake and making boost?
@@JayRussellDuramax it's not blowing without compressor restriction- it is restricted by the 14.7PSI of atmospheric pressure. when hooked to an intake it is blowing into a vacuum. This is counter intuitive but true. I actually learned this from Steve Morris's CZcams channel.
@@bobqzzi It's a vacuum initially, but not once the compressor builds boost pressure - which doesn't take long. As soon as the vacuum goes away, you're in the same situation as if you were blowing into open air. Once you build boost, you're using far more energy than if you were blowing into open air.
@@JayRussellDuramax That's incorrect. Every time the piston descends, it creates a vacuum- if that wasn't true, a naturally aspirated engine wouldn't run. "Open air" is always 14.7PSI.
@@bobqzzi Maybe if the engine is naturally aspirated. If it's forced induction - like this one - positive pressure is forcing air into the cylinders. The vacuum isn't necessary anymore.
Engines operate on pressure differentials. When a forced induction engine is on the intake stroke, that cylinder doesn't go into vacuum, the pressure is just reduced below the boost pressure by the piston moving down and expanding the volume in the cylinder.
Goodness hot dang that is soo FRIGGIN BAD AZZ !!!! When the blow off valve flew off my heart sank but damn that is a cool azz engine. Thank you for sharing and congratulations to those guys
Well... Now we know for sure how much the Jeep 4.0 can take. Can't wait to see what it'll do with fuel injection. Nice video my friend!! 💪🔥
I've been waiting to see these guys find the limit of the 4.0 🎉
That turbo test was really neat, but it didn't show the full story because there wasn't any resistance on the compressor side. To really see how parasitic a turbo is, you should have it blowing through a restriction set to match the desired boost pressure that the engine will operate at.
With a setup like this, I highly doubt it’s be running a full exhaust in the truck….
I waited years for this!!!!
Thank you The Horsepower Monster.
A very important key for the exact mixture mass distribution in single carburettor operation on many cylinders is the correct, ideally divided intake or charge air duct routing between the pressure carburettor and the intake valves. Although the 5K IR RGB UV (infrared channel) of the camera was not active in the video, the start-up colours show quite well how precisely the system works. It is possible to galvanically clean these steel tarnish colours and then you can clearly see the integrated material thermal exhaust pipe average value with every new test bench run.

You guys just got yourselves a new subscriber! Building my beloved little straight 6 to these numbers give my xj a whole new outlook. Reinspired? Check! Can't wait to see the fuel injected performance and numbers! This is truely amazing!
Greetings and huge congratulations to Keith on that awesome world record, and thanks to The HP Monster for happening to be there. I'm getting closer every week to my goal of obtaining one of Newcomer's awesome " basic" 4.6 motor for my ZJ, as long as his price doesn't increase with every new eclipse of the world record ha. Yall take care.
Navarro built a turbo Indy Car back in the day with the AMC6 running ~700 HP. Its nice to see someone following in his footsteps and making huge power with this underappreciated motor.
This is what they call the right kind of crazy! Hats off to you guys!
Been waiting on this video for years!!!!
Absolutely amazing👏 congratulations I never would have thought it possible to get that much HP out of an inline 6 especially with a stock crank and block. Great job.
Stock 6.7 Cummins block and crank have seen 3000hp. Not really apples to apples but lots of times stock stuff is really meaty
Thanks!
Thank you very much!
Oh yea boys, ive seen this man at the dyno testing his engines in other videos this will be a good watch i promise, i appreciate his dedication to testing and improving his combinations even to destruction 😂
What's nuts? That's freaking NUTS!!!
Great job as always Newcomer racing! Always top notch work. And Jeff video is awesome keep up the great work!
Look at the numbers they're getting out of the 2JZ, just imagine what the "4.0" would do if it had a little bit of help from the aftermarket....
Um, it's got aftermarket valve train, ignition, intake manifold, Edelbrock head, custom piping and intercooler with a turbo. That's a lot of aftermarket into this build right there.
The 2JZ has a much stouter block and forged crank stock. Plus much better head. The "unobtainium" 4.0 is the DOHC 24V race motors in Argentina.
Imagine a properly designed crossflow head for the old 4.0. I wonder if they know anyone with a 5 axis mill.
@@BurnerJones
The 4.0 (and ty he earlier 199, 232 as nd 258) has the same bore center distance as the Ford Windsor and Cleveland at 4.380". The SBC and LS/LT are only .020" more at 4.400". The Twin Cam LQ-1 is also 4.400". This presents a number of possibilities for creative futting, welding etc.
These videos on the Jeep inline 6 are why I'm subbed. I know mine needs a rebuild soon amd ive been doing my homework to see whether or not I want to get absurd with it. Thank you for these🇺🇲
Very cool to see the before and after. Great video
It’s nice to watch talented engine builders. Share the knowledge.
Keep the amazing work coming love your videos.
I am Honestly IMPRESSED beyond belief! And it did it at 5500 RPM? WHOA!!!!
Good work as always!
Just now realized I’ve been addicted to the H.M. Channel since it first popped up, but have never hit the subscribe button.
After watching a stock bottom end 4.0L jeep engine post 4 digit HP #’s, I damn near put my finger straight through my phone smashing that subscribe button 😂😂. Well done. Will be looking forward to watching more.
Love it! Thanks! And thanks for watching!
Cant wait to see it in the Rambler!
Nice Channel, I'm glad that I found You.
Very nicely done.
Sick!!!! That’s super impressive out of a 2 bolt main set up.
Super cool engine! It would have ben nice to have a head available for the Ford 4.9l straight six.
Congratulations guys that's awesome
Great film. That's a lot of energy going on in those 6 cylinders. Needs to look at in manifold design before going for the 1500 record👍
Thanks! And thanks for watching!
@@TheHorsepowerMonster No really, thank you, that was a lot of time and effort to get all that information, truly fascinating.
All the best from🇬🇧
This guy's got a whole collection of radically different intake manifolds including a ridiculous sheet metal fabricated one that's probably the sexiest most ridiculous AMC straight 6 manifold I have ever seen
My experience was taking a Datsun 510, converting it to propane and turbocharging it. In 1979. I never sorted out the flat spot between NA and boosted, but I had a blast...until cartwheeling the damn thing.
That was so awesome.. thanks for sharing 😊
Thanks!
You have been a huge miss my friend! How’s the corvette coming along? It’s great to see your still doing well! A awesome video as always!!!❤❤❤❤🎉🎉🎉🎉
Thanks! Got swamped by a couple of engine builds but hope to have more content up soon. Thanks for watching!
20:39 & 21:03 I think they're still called wastegates even when they're blowing off the header.
It is. Wastegates relieve pressure from the exhaust manifold to control boost, while blow off valves vent excess pressure from the intake charge pipe when the throttle is closed
It's a joke.
@@dieseldan420ca .... somehow i missed that
Another great video Jeff, love your site!!
Hey thanks so much! And thanks for watching!
Great job guys , love seeing boosted six’s making some steam .
Always great stuff from you!! Nice!
Thank you very much! and thanks for watching!
That's awesome guys....That's pretty dam close to the zz632 numbers 👍🏿
I can't believe this video was released since the last time a Jeep turbo build was made and broke that record effortless, you guys from Newcomer Racing, are my heroes man, i don't know the name of the guy i think is the owner of the team with the harley davidson coverall and black and white cap, the knoledge, effort and passion you guys put into build this engines, this straight engines that i think not many people care o talk about, is amazing. NOW i can't wait to see This engine with EFI upgrade, maybe ignition upgrade with that prototype sensor that you already made in the last build to have full control of ignition, not mention if you upgrade all the bottom end to push All the limits beyond the std test you're doing now. CAN'T WAIT to see this engine again, of course with Newcomer Racing at his side to now is going to perform the best it can. And of course Thank to Horsepower Monster for sharing all this content that is so hard to see in other place! Thank you so much guys, keep up the work and if possible share this things every time you can!
Horsepower monster continues to impress. Totally exciting to watch. Getting to see world records accomplished is really really special. Thanks for the story and the excellent filming!
Hey, thanks for the kind words! And thanks for watching!
That's crazy 🤪. Congratulations
Great video!
I JUST SAW HISTORY MADE WITH ENGINE WOW = A big thanks guy's ❣👍
Old F-4 Phantom 2 fighter jet Shoe🇺🇸
It's nice, I like it. Good demonstration of why engine management is much better than carbs and basic ignition systems.
we need an update on that rambler!
4.0 videos are the best❤️❤️
Rocks! I want that in my Grand Cherokee!
Great job men
Nothing like a straight 6
Yes!
Great job it was great fun watching 😁☕👍
Dang!!! Now, to share with all the folks that call the Jeep engine a "tractor" engine, lol.
Amazing work guys!! Building a Stroker now, not like this, but maybe one day? Lol
A reproduction Rick Mudge motor would be sweet, too!
All I gotta say is that was mind blowing for sure. I hope this engine will be long lasting.
That's pretty cool for a straight six
Cool build and i as a jeep owner with a mild built l6 that knows how good they are . Thats impressive to say the least. I do wish i had a cam inmine from new comer ut they are expensive tho.
So dang cool. Stuff like this is why i love this channel. Vroom vroom!!
Thanks very much!
Watched this again... I think someone needs to call those POWER NATION guys and tell them to take those anemic comments back. Even the 4.2L is capable of much more than what they did with it. The 4.0 Edelbrock head or one of Keith's 4.0 Cylinder heads onto the 4.2L along with some machine work.... I'd like to see that next...C'mon Keith.
Back around 1967, AMC had a turbo-charged inline-six car at Indy. This same basic engine design, I believe a 199 cu.in. stock block. They wouldn't have believed what you guys did, here. Totally amazing.
Wish you guys good luck.
That engine made 750 hp so I think they whould believe you since it was 50 something years ago.
I fixed my original comment. The indy 6 made 750hp it was the indy 3.0 lt 225 alum v8 that made 875hp.
@@ivanrousseau5066 Are there any videos about that 3.0L/225ci aluminum V8?
Matts off-road recovery Needs this for the banana!!!
I love content like this. Very much looking forward to another A-bomb Corvette vid BTW. It's just great that project. Enjoy every part of it.
Re the turbo loss, the free air HP drop is still artificially low I reckon. What it wants is deadheading into an enclosed chamber and held to say 15psi (or whatever) against a couple of blow off valves and connected to the wastegate to simulate the intake manifold pressure the turbo has to actually pump. That'll give a truer pumping loss indication.
I reckon it'll be around about 100hp loss, which actually isn't that much in the overall scheme of things, particularly when just cruising around.
Yep, that would be a very interesting test! Thanks for watching!
Good stuff guys!
Thanks!
Newcomer rocks!
Simply impressive
Pretty cool video, ty.
Thanks! And thanks for watching!
MAN,it surely would be cool to have awesome friends like yours!!! 😂
I really was expecting to see the head on that 4.0 to blow sky high, and I never would have believed that 1,000+ ponies would be pumped out of that normally anemic 6! Thanks for impressing the socks right off of my feet!!!
Love your content!!!
Ha! Thanks for watching!
A thousand horsepower on stock mains this just blows my mind.
The durability of the 4.0 jeep can't be beat. 😊
love your videos!
very nice job. impressive
Thanks! And thanks for watching!
Awesome! I Drag Race a Chevy 292! I have talked to you Jeff...thanks!
Love seeing a good ol American Motors 6cyl making extreme power that's crazy awesome. Can't wait to see how that Rambler performs. Great job on that build. Could you see if u could persuade Kieth into building a similar 2.5 4cyl ? Would luv to know what that number could be. Thanks for the videos there great . Buck .K.
GREAT VIDEO!
Hey thanks!
I love my homebrew 4.7L NA stroker at ~300hp/370tq but this is epic!
Keep up the amc/jeep content!
This was awesome. Can't wait to see it with fuel injection and a better waste gate setup!
I have always loved straight 6’s and a old friend of mine built a all out drag whine was I Ford Pinto and this guy is a perfections on any thing he does and he powered this car with 300 Ford straight 6 and this was 25 yrs ago and it was super fast bracket car and the car set in his garage for at least 10-15 years and a old friend of mine bought this drag car and he put a supper charged all aluminum Ford 428 and don’t remember what horse power he can but I know he had to put longer wheelie bars on and I never seen him lose and it looked like a stock car until you looked inside and under car and everything inside the car was aluminum sheeting full funny car cage with a parachute on back that was required in the rules they have had. And being so short it was a hand full but if it launched perfect it went straight down the track in low 8’s but if you did not get it in the groves and perfectly straight at the 60’ marke he would shut it down . And when this pinto straight 6 half the motor was inside the car with you and the 428 there were about 2-4 cylinders in car with you and he had a big following at our little drag stripe with the straight 6 300 Ford everybody knew the Pinto was warming up for a run and everybody would run to the fence to watch him go because there was not any 6’s on that track but for the life of me I can not find one of his ticket that printed out all the speed reaction time 60 ft mark. A great time for a guy built this car from scratch by Leroy Horseman !
When most people start conservative at like 5 pounds and they just jump off with 26 pounds of boost lol
Am I the only one who noticed the self tapper just absolutely sent into the CRT frame? Gotta love old tech sometimes lol
Hopefully this leads to seeing more jeep. 4L I6 builds. It'd be cool to see what other people can do with the engine after seeing this potential.
What's the pressure differential in the exhaust manifold vs the boost pressure? That number will tell all about the efficiency and optimization of this setup, as anything over 1.5:1 EBP to IBP is massively wasting pressure for no power gain. I won't even talk about cam specs, yet, but given the N/A power numbers I'm relatively certain that can be optimized as well.
David Vizard teaches and shows that you can get roundabouts 1.4ft-lbs per cubic inch N/A at 10:1 compression on 87 octane fuel and as long as your heads aren't absolute trash, most of that will come from having the cam right, which he discusses how to do in his myriad of cam theory videos and books.
Love seeing I-6's making ridiculous power. They are almost always known for being insanely stout; so why not?
I love it... That's one mean ass 6 banger..
That’s SICK!!!
No, actually, it's pretty healthy.
@@mattlf9120 😂
Frkn awesome!
You mentioned about making that engine a drag and drive engine and since it is a straight 6 you can fit it in a small light car and run good numbers all week long and when you said that I was going to suggest putting that engine in a car and go drag racing with it but I would try to beef up the bottom end a little bit like getting a set of billet main caps for it and put ARP studs in the entire block and then you just have to worry about the block splitting somewhere and I think going EFI would be a great move for the engine so you can dial in each cylinder and keep it from going lean especially in the center cylinders
Algo- ment. Awesome
I miss seeing you working on your corvette. When do you think you will be back working on the corvette?
Do you think heat wrap on the exhaust could help with your issues with going lean? If not what about the heat shielding found on the newer wranglers with the 4.0?
1100 HP at 5500 RPM! What's the Jeep block made out of? Tungsten?
Impressive
Sounds like its having some spark problems, but awesome job! Almost 30psi on a stock 4.0l block and it lived to tell the tale, thats incredible.
Heck, I would’ve kept my 98 Jeep Cherokee limited 4 L if I knew I could run that much horsepower.
