- A few years in the making, this one of a kind V12 LS1 engine has been pieced together by the Corish brothers at V12LS.com. In essence it’s two GM V8 LS1 alloy blocks and cylinder heads shortened and grafted together using a custom billet crank and camshaft. The beauty of the build is that engine still retains many GM parts. This prototype engine will be heading to the US soon for testing. The good new is the guys plan on making these engines available for sale next year.
We were lucky enough to witness it on the dyno at Dandy Engines where we were surprised at how smooth and easy the engine delivered both power and torque on regular unleaded petrol.

don't hate on this. the fact that someone was able to make this happen demands respect. how many machinist do you know can do this? truly remarkable.
No hater here, fantastic feat of engineering.
shinavea its kind of like putting a tuxedo on a caveman. But great work.
Actually I'm sure there are many machinist with the Ability to do, just not the time, money, or a reason. That's not saying it's not cool though.
Wasnt the first vipers engine built like this
Exactly...
Cleetus McFarland needs one of these 🤔

@Ryan W get the hell outa here.
Put this in the new rear engine Corvette. Ferrari would be so salty
it be too heavy
Stopsign32v well Ferrari mostly have a 4.5L v8
@@Skizzy7777 if you weren't the son of God I'd let you know my feelings.
Ferrari = V12
Doesn't matter if most Ferrari's today have 4 cylinders in them.
Is salty black talk?? Lmk
@@jimmyatxallday9924 I'd say it's mostly white talk. But dats rasis wut you said Jimmy.
I love how its exhaust note has a balance of V12 and V8 to it at different RPMs, it's oddly mesmerizing to me.
V8 at low V12 at high
That's because the firing order is not the same as a typical v12, plus there are constraints in the header design.
well, now you can legit LS swap a Ferrari or a Lamborghini
made me laugh !
fucking lol Tyler
#LStheworld
A little jealous I see.
Lol still to big! Won't fit in one lol
Next we will be testing the motor with turbos and breaking the dyno. Stay tuned!
I'm weary of how the two shortened blocks were "grafted" together. That's sounds sketchy AF when it comes to power adders.
Over 7 hp naturally aspirated using stock parts. This engines potential is insane!
Right, could make 1000hp with a couple bolt ons and a tune N/A. Imagine a set of turbos on dat thing. This engine could probably spool up a pair of 88s or larger no problem.
Lol 7hp
Ha 7hp
That’s a whopping 0.8hp per litre! These American engines are catching up!
@@devlintaylor9520 Well, he's not wrong
Cadillac NEEDS to drop this in something awesome.
Cadillac utilizes the GM 6.2 from the factory already.
Jon Bradfield
I would think using this engine in a modestly revised version of the El Miraj, or they just build the Sixteen but call it the Twelve instead, or an Aventador sized version of the Cien.
Jon Bradfield Not against that at all.
CT6 V 12.
Maybe a Mercedes S600 competitor
for everyone whos comparing this engine with other modified V8s.. this engine has stock LS1 specs (bore, stroke, compression, heads, etc).. stock LS1 has around 330ish hp?? and people still manage to daily it with some bolts on and boost at 600 or even more. Now imagine same modifications goes into this one, i mean little bost with some bolt ons and heads job? it is possible to daily a 1xxx engine with the same way you do with a 600 ls1.
Exactly right Ahmed, it makes more power than a Hellcat, and a Viper 8.4L V10, with essentially stock LS1 internals and heads. The cam and valve springs are the only real performance modification. It's only a matter of time before these things see bigger bores, better heads, rods that can spin past 6,500 safely, intake, exhausts, etc. 1000+ hp in NA form on pump fuel is not out of the question.
I'm sure someone will add boost at some stage too, just to see what happens.
also some matched ports & a polish will help, along with a better exhaust, the flow dynamics are not optimal with 2 seperate manifolds.
Ahmed Alansari ok ...so I can take 4 old school stock 350s join them together and have a 800 HP monster that weighs 2000 LBS and is 8 feet long...this whole concept is stupid because you lose the sweet sound of a v8 and to big long and heavy ...ambitious tho...gotta give them that....
yeah none of that is likely to ever happen or become mainstream. this is a one off and is not practical for any mainstream application. the cost associated with something like this you could probably build two 1000hp v8s with fewer parts and smaller size/weight.
k moods except you can buy one of these engine for 30gs online...probably the cheapest v12 crate motor you can buy
Flagged for porn...
lol exactly
hahahhajajjajajajjhahahhah
It's SO smooth.
Ls1: so good it's even good as other engines
Did nobody else notice the Brake Specific Fuel Consumption figures? Shows unreal numbers...like a diesel engine at 0.369 average. This alone makes this engine fantastic. V12 power and smoothness with good fuel economy under load...fantastic
Now people can make more convincing 250 GTO clones with their Datsuns.
LOL That's awesome.
lol
you could make an old Chevy 250 straight six sound like a 250 GTO when built right. This LS1 v12
doesn't sound anything like one
😆😆😆😆😆
@@spartanboss4189, I simply cannot imagine any Chevy 250 sounding anything like any revvy old Ferrari V12, ever. Expecially since the things were generally all done by 5k, which is lower than the torque peak in a 250 GTO.
All this thing needs is a proper set of tubular headers, and an exhaust system with an X-pipe.
imagine this engine with a set of 76 mm turbos......
2000hp capable at least...
Easily .
Why only 2 how about 4 because America
Nelson racing makes 2k with 8 cylinders all the time lol.
And no way to put all that power to the ground. lol
@@TheBeingReal yea there is. 20 psi of air in drag slicks
Seeing us Aussie showing the world how it’s done we punch well above our weight
I’m not super big on v12’s, typically for the sound, but this. I like this. It’s not loud and annoying, it’s still throaty. Moreover anything imagine the potential of this beast
Look at how little it shakes and vibrates across most of the RPM range. Mmmmmm mmm!
A 700+hp NA pump gas V8 is an angry and lumpy engine compared to this. This engine (off the dyno) sounds a lot more like a really big capacity sports bike, and is really smooth once it gets up over about 1,500rpm. The 30/90/30/90 ignition split gives it a bit of a lumpy note at idle, a bit like a V8.
The fact that it is essentially 2x straight 6's means it has a perfect balance too, which is one of the reasons it is so smooth.
WarWagonMT 2slant 6's* lol
This is pretty awesome, and the engineering that went in it is also amazing.
Love it! Love me some LS architecture, and I really love the balance and sound of the V12. Best of both worlds! Kudos to the team for building this.
I’d love to build a 3/4 scale P-51 replica to power with this. Like a Thunder Mustang but with a 12-cylinder LS. The Falconer V12 was also based on GM architecture, but the older SBC style. I’m diggin’ this update.
Thanks for sharing!
I'm not particularly crazy about LS motors, but this is definitely a work of art to say the least.
Imagine puting that in the new corvette😂
lol not that good for weight saving matters
@@Abdullah..S yeah indeed, but some forced induction would help just not with the corners lol.
@@Abdullah..S it would probably be more balanced than any other car because of where the motor would be sitting though 🙄
This thing could *easily* make over 1000hp with a few modifications, this thing's a beast!
Dear lord that torque curve
What you guys are not getting is that other than the larger than stock but very conservative cam, this is a stock spec engine but in V12 configuration. A stock LS1 is 350hp. This thing is making over 700. Thats more than double the power of an LS1 V8. whambodius talking about easily making that with a 540 or 496 which is correct, but you can easily build this engine with a larger cam, a set of bad ass heads and a better intake because this style intake sucks ass compared to the composite intakes, and some true long tube headers and be over 1000hp. Remember this is a stock spec engine meaning stock bore, stock stroke, stock unported 241 heads.
And last time I checked a stock viper was 645hp and they are putting down around 550 to the wheels so not sure where you getting the idea that the vipers are "basically putting that to the wheels" unless you mean "built" vipers. This engine can be "built" also.
The stock Viper is also running an EPA tune with a stock cam through a stock exhaust with cats and sucking air through filters. A quick tune adds 28 HP and 44 TQ to the wheels. I don't know the gains if you added a performance cam in there and the stock cam is pretty good, so probably about the same gains. Don't get me wrong, I think this cool, but there is no magic here. Unless they get mass produced for cheap, I don't see a market. Either way, props for doing it.
Built? lol have fun paying ridiculous amounts of money on minimal gains cause no one has anything for this engine
I know they don't. But it does have to have a set of heads and cam to run lol. The builder could have used cnc ported heads and a much larger camshaft. The point the builder was making was what would a stock or close to stock spec LS1 yield in a V12 configuration. Heads and cam swaps on V8 LS1's will net a 100hp gain. It seems that this engine responded well to adding the extra 4 cylinders. The power doubled on this engine by adding half the number of cylinders. These guys didn't set out to show how much power they could make with a V12 LS1. Thats what I think some people are taking away from this video. It was in no way a "lets see how much power we can make with a v12 LS1". If that was the case they would have NEVER used this cam, NEVER used those heads, NEVER used that style intake, and had a much better set of of long tube headers. Hell this thing has exhaust manifolds on it for Gods sake. Im really surprised they got that kind of power with that intake manifold on it.
I dont really see a market for this engine honestly. Leave it to the the aussies to do things that nobody else will. Mad respect to them for that. Those guys are all the time building some wicked stuff.
it all starts somewhere, most engines didnt have an upgraded path until people put time, money, effort into developing upgrades for them. same thing for this motor, it might not have much of anything right now, but it does in reality, and upgrade for an LS will work with this except for a crank amd cam.
madmax2069 LOL Huh? Let's see if you're preaching this story when you hit clearance issues. This motor will bring with it more issues than what it's worth.
good effort for unported 241s and those exhaust manifolds. plenty left in it.
GM sells small bore LS3 heads now, probably a better option that early LS1 heads.
i think they wanted to make that impression, or the boss said JUST DO IT.
***** read my comment.
SMALL bore ls3 heads .
They work with the ls1 3.9in bore
The next blocks we have in the works right now are 4.125 inch bore, so will open up a lot of possibilities :)
241s are just 243s with a bigger cc. mill em 0.020 and they match a 243 power wise (had both on an LQ9, stuck with the 241s and sold the 243s for 600 profit over what I paid lol)
while im not a fan of any LS, i am a fan of wonderful engineering and you sir, i tip my hat to you 🎩🎩
I see a quad turbo set up in the near future!
check out Steve Morris Racing Engines they are developing a ls based all billet V-16 Quad turbo Monster , Unfortunately it is Not available over the counter , it is for the Devel Sixteen super car . . . a Pitty I'm sure . . .
Big Roots Compressor would be more practical imho.
Hats off to you for even attempting this! I have always wanted to do a Mopar Hemi the same way.
Good luck!
Sounds real healthy! Wow!
Sounds like an old Jaguar V12
This would be nice for a Jag swap.
V12s sound like - well V12s. True that.
12's sound like big 6's, really not at all intimidating. Only american v8 and harley v2 will give you that raw rumble sound.
Not even close I think you need hearing aids.
Always nice to see when engine builders worldwide make custom engines like these. Imagine the future with modern motor tech. The possibilities will be endless. Keep up the nice vids Fullboost.
I like the sound, especially at 1:48 when it mellows out a bit before the pull starts.
I would have really liked to have heard the exhaust note from the tail pipe. Very impressive.
This is the engine my 1980 Ford Pinto station wagon has been waiting for...
I would love a carb and epa compliant supercharged gasoline directed pushrod 2 liter transverse v8 crate engine to mount in fwd based cars.
Best sounding V12 engine I've ever heard! Nice and throaty!!!
Ford guy here... this is gorgeous and I NEED it.
Always love seeing stuff like this. they could make more power with bolt ons but its unique and awesome
Thanks! This is an exciting project, and there is much more power to come too. Our goal is 1000HP with LS3 style heads on pump gas, we will start on that as soon as our cast blocks are ready.
I can't even imagine some of the engineering and fabrication challenges they had to have tackled to make this work. Were a couple of LS blocks sectioned then welded together?
John Shaft yes they cut the last two cylinders off and welded the blocks together they also made an ls1 v4 by cutting a v8 in half and welding everything back together
@@-thebatman- they casted the block in one piece from ground up
I think 900hp is possible with the right aftermarket parts.
Really impressed by this engine.
Another super impressive feat they accomplished here was getting it to sounds just like a V8. The firing order and exhaust header cylinder pairings work together to produce the lovely V8 sound. It looks deceptively simple with four 3-1s, but I guarantee it wasn't. I challenge anyone to find another V12 in existence that sounds like this one.
Very creative, guys, and well done.
dont you just love it when people quantify a piece of engineering triumph and beauty in a pissing match? yeah me neither.
the point of this is not to build something better that a big block or something thats the end all be all motor that will stand at the top a contrived pile motors as the and claim to tbe the next hemi or boss 429 or 2jze. its to have something different than anything else. i live in pigeon forge tn, we have 4 rod runs a year. this is what its like walking down the street..... big block, small block, small block, big block, small block, big block, big block.... same ol, same ol. but now when you come across the dude that shoe horned a lamborghini v10 into the back of a s10, people loose there shit including me! about the only time no one gives a shit about a care is when the "camber kids" show up. its a amazing motor that makes great power and sound cool as hell that will bolt right up to a t56, 700r4, turbo400 take your pic trans that someone whos oke with being different can buy and build something really fucking cool and still go fast ! stop trying to put it in a contrived race against big blocks with bolt ons and nitrous, its just retarted.
Rocco Rocks ,all of us in Sevier County agree... with all that, lol
people. since the exhaust is being routed out of the room, we are not hearing the full sound of the engine. this thing sounds amazing if you compare it to similar set ups
The sound reminds me of a W12. Also I love how it still sounds a bit like a Corvette, that's crazy
I can just imagine the tormented faces on Jag purists when somebody pops this in a Series II or III, maybe an XJ40, and pops the hood...
Holy fucking cow. I'd much prefer this in the Corvette ZR1 to a blown V-8. The V-8 sound, while glorious, is standard in every "ordinary" Corvette and in many Camaros and Mustangs and other everyday cars and trucks. This sound would make the ultimate Vette even more special.
Secondly, I love the thought of having this V-12 in like, a 95 Camaro with no Z28 badges and a relatively quiet exhaust system.. Ultimate sleeper. Rev it a bit at a stoplight, the guy next to you will think it's a six!
Someone is a legit machinist. Impressive.
Oh, the many joys. Great job!
Could you imagine your stock engine with no turbo or supercharger, nothing fancy at all, making over 700 hp.
Nothing fancy yet it's a v12ls lol rethink that one atleast once there pal
You mean like the Italians already build???😕
The One-77 and the TVR Speed 12 both do this with ease, with the latter being rumored to have over 1000 horsepower unrestricted. It's not unheard of but still pretty awesome nonetheless.
What body was the builder planning to drop this in?
Any car that comes in Straight Six and V8 configurations, will have a big enough engine bay.
That crazy flat torque curve would make this a very easy daily driver, perfect in something like a Chev pickup.
Doing it using 'stock' internals is an achievement - the one true advantage of the LS over the Ford and MoPar engines, is that the parts to service and repair them are everywhere, and at affordable prices.
Thanks for the interest. We have put these in 2 first gen Camaros, a cheetah and even our kia work van. A few more applications coming but I won't spoil their SEMA reveals.
@@V12LS ,..... I wonder, how big is the engine bay in the new Corvette? "Mid mounted V12" is such an appealing sentence ;)
@@PiDsPagePrototypes It's too small of a space for the mid engine but a really great idea if they plan on increasing the length of the vehicle. Now that would be badass. (You can see the engine through glass byusing the rear view mirror) The new Corvette sends chills down my spine.
@@UltraGamma25 Length? V12's are mounted sideways ;)
Just have to make use of the new 'Vette's wide hips.
@@PiDsPagePrototypes not all v12s are sideways. most arent actually
That engine is the best sounding engine ever built! If it could rev a bit higher, it would SCREAM
We have a short stroke, big bore V12LS with NASCAR valve train in the build ;)
FINALLY!!! a V12 ls crate motor in the works! I've been looking a pages of the prototype for years, it's nice to finally here this motor run.
Now please give it a ram; style intake manifold and long tube headers....
that engines surely doesn't wanna rev, but 717 hp is plenty.
Its not often i see a fellow fur on a vid like this
This is almost how Bugatti’s first w16 came into being.
makes just as much as a viper v10 and is only .1 liters larger and it doesn't have long tubes ported heads or a very aggressive cam this thing could be a beast.
I love the sound. it's like it's confused on whether it's a v8 or a v12
I'm laughing my ass off at the comments and speculations about why they're not "revving it higher" and that it probably has a lot more left in it. Its basically a gimmick engine and V-12 or not, its still a cam-in-block, 2-valve V-type engine of large displacement compared to the small, high-revving "supercar" V-12s the car "experts" here are apparently comparing it to. Adding 4 cylinders to a V-8 doesn't make it an engine designed and engineered to be a V-12 from square one, and once you hit the point of diminishing returns on a dyno pull where increased speed doesn't outpace lost volumetric efficiency and torque, you're a complete moron to keep running the engine faster when its not gaining you anything. Not to mention a factory LS1 V-8 redlines around 6500 rpm.
So who in their right mind would expect this morphodite V-12 to spin faster when it's already placing significantly higher loads up to 50% higher than stock design levels on keep components that were designed for a V-8. Do you think the timing gear train is somehow 50% stronger just because the block and cam are longer and the load on the cam is at least 50% higher? Not hardly. How about the neutrally-balanced harmonic balancer that even if a hjgh-quality afermarket unit was still designed for a V-8 engine firing 8 cylinders every 720 degrees instead of 12? Does simply being made of "billet" make the crankshaft 50% stronger at the same time its subjected to more than 50% more torque behind the back connecting rod journal?
I swear I get mechanically dumber every time I look at CZcams comments where a bunch of wannabe "experts" who probably can't change a tire are drawing on their fast knowledge, experience and education gathered from reading car magazines, watching Fast and Furious movies and playing video games start passing it along to others.
So true Chad, the comments section here has given us many laughs over the past months. It's also strange that people assume we are anti small bore exotics, which is far from he truth as I drive a beautiful Italian V8 on most nice days, and we have a lot of experience with other engine types like the rotary also. This engine made a little over 1.5x the same spec V8 would, and revved exactly to where that cam tapers off in a V8. I'm glad you point that out. We are expecting the same 1.5x+ results form our new cast iron V12LS blocks, and can't wait to get those on the dyno soon! The target market here is people wanting something different, we are tired of seeign the same old crate engines over and over again.
I'm your target market!
Chad Meyer Steve Morris devel sixteen v12 kicks ass look at that
you sir just Punk'd CZcams
Chad Meyer get off the dope, nobody cares about all the shit you typed it
This is awesome. Want in my truck. But why not a V16?
That would likely have to be done in a W formation instead of a V
Search Nelson Racing Engines
Daniel Robinson you’d be looking at a very long crank at that point, in a block unable to support it properly. Could be prone to torsional flex or complete engine failure.
Hard to make it fit, and flexing as mentioned before.
V12 engines are the most stable V type engines. I prefer OPOC myself
finally v12's will be coming to America!!!
I love it, I’ve been daydreaming about this exact idea, the exhaust manifolds look like bought ones ✅
Should've went for a V16!~
Imagine if this went into new C8 Corvette.
Unfortunately the engine costs more that the damn car
@@ironicchannelname6457 That engine, with the technology as far as I know, that was explained about it... I didn't think so. It seems very basic in terms of technology. In anyway, building this is a huge work, and it is very specific.
@@mrmmk12 yeah but 55k is ridiculous it almost like they don't want to build anymore
it's just as awesome as this one guy who made his own custom ford v 12 from 2 302's and multiple cleveland heads, he wanted to make a le mans motor that ford never made. this was a few years ago. a great concept for both companies to try out imo.
The sound it makes is like a mix of an old M3 and a Diablo I love it
whoa... pardon me while I retrieve my jaw from the floor!
This is engineering porn! And as a fellow curious engineer, I like it a lot!
why does no one understand😲 this is basically a budget build and does not represent the full potential of this engine. yes you can turbo an ls1 and make more power, yes a built 496 can make more power, and yes you can do this or that to that engine and it will make more power. (At the end of the day, those engines will still be those engines, and not an ls1 based v12.) But you must compare apples to apples, and oranges to oranges. this engine is basically bone stock performance wise. turbo this engine with the same amount of boost as the ls1, build this engine to the same level as the 496, or do this and that to this engine. now which makes more power? if you said one of the other engines, you are lying to yourself or just being stubborn. (not saying that there are not some engines out there that will not produce more power no matter what, but for most PUMP GAS engines, I believe this holds true.)
Chevy made a prototype v12 corvette back in 1992 its in the chevy museum. The engine was made by FALCONER and it was a all aluminum, 600-cubic-inch, 683hp, 680 lb-ft V-12 look it up its crazy.
Fair do's by these Aussies expressing torque in Lb/ft and Power in HP rather than KW
I want this in my el camino
this thing sounds weird... i love it
Good lord. What a refined sound on start up.
Lets not forget that this engine is a V8 LS1 which has 4 more piston block welded onto it to make it a V12, so just imagine if the forged a V12 block based on those spec or casted a 6061 aluminum block and then had special pistons to match like the same used in LSa engines and also the special oil feeding system built into the block internals and also special grade of bearing caps and 12 bolt mains with side bolts to strengthen the crank main caps also larger oil/water feeds and design a specialised copper casket to suit, better cams and hi revving Cranks, hi flowing heads and then a supercharger to suit or twin turbo to suit, take you pick, then you have a engine which will make at least 1,000 HP all day every day and bullet proof as long as all the micro measurements are done correctly during assembly and the blueprinting of everything that moves, weights balancing of every moving part ? Basically a Hi HP V12 to be used for drags street and every day driving, now thats what these guys wanted to get too in the end, its one thing to make a working V12 LS engine,but its a totally different beast to have the same engine made for all the uses mentioned above ? Good luck to the australian guys who made this beast. :) cant wait till they make a better improved version with various performance options made from the best alloys and metals on the market to prove to the world of engine building we have what it takes to beat the rest at their game,. like Farri, lambos and other V12 engine manufacturers and not have multi million dollar machines and 100's of engineers working on a engine to get it right, after spending millions on R & D just for the engines side of things ? these guys made this engine in a shed, with trial and errors made to get to this stage ??

I've never seen so many engineers commenting on the same video. I'm pretty sure I can't build a V12 let alone make suggestions on how to make it better. And I've been an auto technician for the past 25 years.
Keyboard mechanics. I thought I was pretty clever building this thing, but it turns out I have done it all wrong after reading the comments, lol. Maybe I should have put a turbo on an iron 5.3 instead.
A lot of people like and appreciate it for what it is, but there is always someone who needs to pump up their own tires by saying they can do better, yet I haven't seen too many complete custom engines up here.
You need 180-degree headers on it
Nice power and torque curves.
This is awesome. Now someone needs to build an inline 7 cylinder out of 2 barras.
They should do a V12 version of the 7.4l LSX. That'll be a 900bhp+ 11.1 litre V12
What would you put and 11.1 litre engine in what is that gonna fit in
Next stop, Twin 72's and 1600 hp
Chris Carson haha that’s probably LOW boost too 😂😂
I can forsee the future of many engine bays
I love reading all you little Comment Mechanics yet none of you have or will ever invest in the time, money or engineering to pull off a build like this. Any one saying "oh but this engine is better" or any variation of "yeah but this makes more power" is the classic CZcams numbers fanboy. This is cool AF, and if you're a real car guy you would respect it and enjoy it.
What if you cut it down the middle and then you have your self a LS based INLINE 6
There's some already. I think I recently saw a land speed car using one. There might be recent video on CZcams actually
Well it's not really an LS1 anymore haha still absolutely SICK
Thanks Peter, we can't wait to show you all the cast iron 9.5 litter version which is in the machine shop now!
Wow, naturally aspirated. Pretty impressive
Perfect candidate for a quad turbo set up
Our thoughts exactly with our new one piece casting iron block and LS7 heads :)
Small video of it making noise
czcams.com/video/zl4pLsibMgw/video.html
I hate to say it, but it doesn't sound good to me. I'm hoping it's just the camera's mic... :-\
its because of the firing order
+Joshua Huffine I think the 302 v12 sounded better,,
Well there is no headwork done to it, no custom exhaust manifold and no custom header back exhaust. It will definitely sound different then. It's not the best sounding motor but it makes some power.
It will sound like an inline 6 since you cant pair the 2 banks of cylinders exhaust into an x-pipe as it is a 90 degree bank angle and odd firing? You would be able to if it was a 60 degree v12.
It's using OEM style headers so it won't sound that good.
When custom long tube headers are made then it will scream!
Everyone in This comment section is strangely respectful. Rare on youtube.
*_Supercar powered by a V12 LS1..._*
Can't wait to see it
I hope someone build a mid engine corvette with this motor in it I want to see a Paganini killer corvette
717hp?
what about with a ball bearing 90mm turbo?
Keep this beast N/A the sound is more valuable than the horsepower increase 😉
I can only imagine how much better this would be with a short stack Borla ITB induction.
Funny how it still has that American block sound
sounds like starving for fuel. why not a flat plane crank?
Flat plane crank would only apply to engines with 4 or 8 cylinders.
You don't need a flat plane on straight 6 or V12 they are naturally balanced and there would be nothing to gain.
GlassTopRX7 Putting a flatplane crank on a v8 would just introduce super rough secondary non sinusoidal imbalance.

Flat planes are great in V8 just not in a large displacement V8, even the Voodoo needed a rather heavy crank shaft negating nearly all the advantages.
GlassTopRX7 The lighter crankshaft can actually make you lose power, what it does though is have less of a flywheel affect so that rev response will be more snappy. Crossplane cranks usually do not have the center 2 counterweights, it has been a known practice for racing teams to incorporate the center 2 counterweights and gain a few horsepower across the entire rev range, NASCAR and Austrailian V8 Supercars series are sole proof of this. The flatplane v8's main advantage is that it has even exhaust pulse intervals on each cylinder bank, which makes a huge difference in scavenging at higher rpm. Overall, If you want a truly pure race setup, your engine would be a stressed component of the chassis (block bolted directly to suspension) and a flatplane v8's secondary non sinusoidal vibrations is a huge red flag and should'nt be used as one. The only way to balance the secondary vibrations in a flat plane v8 is to use quad balance shafts which each rotate twice the speed of the crankshaft. Crossplane v8s already come in secondary balance but are out of primary balance due to the end pistons not being in the same position, this is negated by the heavier counterweights on each end for a near perfect smooth engine.
Great engineering, but geez guys, this sounds like a Grey motor.
Both sides prob running in the same firing order, so sounds like a 6
That's because it's basically two straight six's. What else is it going to sound like?
Caesium147 No euro V12 sounds like a Grey motor. This does... and it sucks.
+ArchimedeanEye nfi....

I didn't say anything about euro V12's.
That trottle response is like the worst turbo lag ever on a non turbo car
The dyno controls engine load not the throttle body. Perhaps read up on how a dyno work. Cheers.
Thanks for the interest. This is a commonly misunderstood function of the dyno as most videos online simply allow the engine to rev up as quickly as possible. If all you care about is peak power that's fine, but you miss out on a lot of data to get the tune right. The dyno operator controls the load. Think of it like going full throttle in park, vs on the flat, vs up a big hill in 5th. It's all up to the operator what conditions the engine is put under. If you want to learn more, HP Academy and EFI University have some good online courses for tuning.
I like how this design sounds like a traditional cross plane 90 degree V8, it seems to operate as one and a half V8s instead of other V12s that operate as two inline sizes or two V6s with a 60 degree firing order. I think I have heard a V12 design another company made from an American V8 and it has the 60 degree firing order that didn't have the same pleasing exhaust note.
put a pair in a boat.
Some Liberal countries are trying to ban V8 automobile engines but they didn't say anything about V12's! Ha. ;)
you're inept and uneducated if you think any of that is true. not everything in life is liberal or gun toting aerosol cheese eating American. you thinking that merely ratified my statement

Google is just a click away fella.You can barely put a sentence together properly but I'm the inept and uneducated one.Aerosol cheese? wtf lol
Col. Angus you're not smart enough to figure it out on your own, must've been your first day on the internet.
Mark Nope
I'm smart enough to know that grammar is not your strongest suit.
+Col. Angus you're right I don't care enough about typing things to children to place a capital letter at the beginning of a sentence. are those words too big for you to understand?
Now hopefully someone builds a gnarly exhaust for this thing. It sounds a little disappointing but still super cool.
