Inside Synergy Auto's INSANE 2.4L V8

[@Dustrunnersauto]

If you guys enjoyed the video, please SMASH THAT LIKE BUTTON. It helps the channel out a huge amount and helps KZbin put the video in front of more people. Thanks for watching 😬

[@sepg5084]

High rpm engines only have torque problems if the gearing is wrong. One shouldn't use the gear ratios of an engine that redlines at 6500 on an engine that redlines at 10000.

[@wololo10]

thanks! people are just dumb nowadays

[@joshuaszeto]

I think swapping out a final gear might be the most cost efficient way but I am not sure how available those are. I do wonder if this is a small price to pay for using less custom parts which seems to be one of the driving ethos of their designs.

[@Adam-ub9nu]

Christ Almighty, somebody that has common f*cking sense!

[@DB-fn3fz]

There's more to it than gearing. Power band is a thing.

[@aidanstubblebine2197]

If my fg2 civic had the same gearing as my buddy's fusion sport, my civic would not be faster haha 😂

[@erisgh0sted961]

I love small displacement V8s. I gotta see one of these.

[@CS-lh3oz]

There are actually a couple pretty cool custom engines derived from OEM engines. There's the V12LS mentioned below, H1 MAXI V8 made from 2 Hayabusa engines, and MV4-ZR V4 made by Motus, which is basically a LS V8 chopped in half.

[@alexwesley6829]

Not to mention the I4 made from a LS cylinder head 😊

[@alfredotovar8984]

I would love to see a video on the BMW P60B40 engine that was used in the E46 M3 GTR. So much of what people know about that car is based on video games but I would love to see more information on the actual car itself that raced ALMS/24Hrs of Nurburgring. Always happy to see a new upload from this channel, keep it up man! 💪🏼

[@DB-fn3fz]

Saw that car and motor at the BMW factory in Germany. That motor was supposed to be used in the E92 M3 but never made it do to torque and smoothness issues. What an engine though...

[@blazbohinc4964]

I'm still waiting for an engine design that runs on stochiometric ratios, uses overpower cooling for the block and has a filter system to deal with NOx emissions. Best modern engines consume at least twice the needed fuel just to avoid high explosion temps, block temps and exhaust that's hard to clean.

[@rickcupola6262]

Don't diss properly engineered modern engines. OEM engines just don't run richer or just to make more torque like the aftermarket does. OEM's have prioritized the swirl flow for optimal mixture so they can make more power for the same amount of fuel and enable the ability to run on much lower octanes of gasoline, and then cram boost into it and toughen up the engine block. While a 500hp head ported turbo K24 from the aftermarket is cool, it might be running a bit rich with 93 octane, but the Mercedes M139 can still run 91 octane and produce 416hp while being reliable and passing emissions and fuel economy, despite being on high boost.

[@braziliansheetbox2497]

You mean any modern turbocharged engine ?

[@tlovsoe4211]

what is overpower cooling

[@mikemoore5929]

In your drawing of the reversed head , you have a hot V shown , was this going to be the original design that changed ?

[@mynameisoversteertorqueove5004]

Opposing piston is not at bottom dead center, unless each piston has it’s own throw on the crank. On most V-8s, opposing pistons share a throw. This means that the opposing piston is always 90 degrees away from it’s counterpart in a 90 degree V-8. This will be true for both flat-plane cranks and cross-plane cranks.

[@erisgh0sted961]

This engine is awesome, but $70k is beyond reach for most hobbyist. If they're making race car engines that's fine, but don't act like it's the small displacement, high reving v8 the aftermarket is looking for. Because until it's less than $7k-$10k it's basically unobtainium.

[@MickH60]

That's completely naïve or unrealistic, try building a performance anything with just 7-10 grand... 70K is cheap for that level of engine...

[@SchroedingerK]

Have you heard of Hartley Enterprises? Hartley has been producing 'busa based V8s for years now. They have an inline four and are working on a V4. Not sure when the V4 will make production, but sounds cool!

[@toraja04]

It’s like a really toned down F1 car! Sounds great 👍🏼

[@marjoh669]

Coincidentaly 2.4 V8’s were used in Formula 1 between 2006-2013 (with the exception of the STR-1 which used a de-tuned V10)😅🤣

[@Iamwolf134]

Nowadays, Synergy have their next generation version of that engine, based on the BMW S1000RR engine this time.

[@johnnyk5]

K24 based inline 6: the K36

[@troufoot]

Love the videos, how about a 2.8 Duramax video

[@jamesmarsh1831]

It is a common practice for just about every manufacturer of a v-4, v-6, v-8, v-10, v-12, v-16 gas or diesel engines to manufacture one style head except for most overhead cam engines, that can be turned 180 degrees from each other and be installed on either side of the engine block or any V style engine for that matter it doesn't make any difference heads can be swapped from one side to the other, plus it saves money not having to engineer and manufacture two different heads identical in every way except they are reversed or mirror images of each other.

[@korn111685]

I’m ok with small v8s. Any v8.

[@Sir.VicsMasher]

If I had the means I'd commission a Honda K20/24 based inline 6 cylinder with heavy duty cast block and head since billet is typically race only.

[@AnDrEw122100]

There’s a company that makes a cylinder head for the Datsun 280z with the inline 6 that’s actually a k20 copy but with 2 extra combustion chambers obviously . Only thing is it doesn’t have ivtec system . But it’s still a k20 copy that bolts onto the old sohc Nissan engines , super cool .

[@mikea5205]

@@AnDrEw122100 - Wow that's pretty awesome!

[@yankeeairpirate1799]

I have a s2000 with bad engine ... would synergy v8 fit the car?

[@rock-uu7qr]

Those have large engine bats I assume you could fit one

[@nickmudd]

One of my fav V8s is the Toyota/Lexus 4.0 V8. It's small and mighty

[@MickH60]

If they turn one head around, and being familiar with these\ motorcycle heads, I would love to see the cam / cam chain set up...

[@arthursmith5409]

Wow, so, these engine's rev like a serious 2 stroke correct? Just thinking, if these high revving engines is mated to the right geared transmission and rear end gears, this engine would be a huge revved out power beast?

[@fuselpeter5393]

Isn't that a similar concept to the engines radical produces? Sounds awesome.

[@darryljosephsmith2725]

Good day , I was wondering if you can put a engine like that into a volvo 245dl station wagon. I want to overhaul it and I want to replace the engine brz v8 2.4l . And use the car to sponsor the supplier of the engine. . I am from paarl and no one has a rare classic volvo 245dl station wagon on the road .

[@yeanah2571]

This design philosophy would make base model Mustangs and Camaros MUCH more appealing. Imagine a 2.3L V8 instead of the Ecoboost? Or the Chevy one with pushrods? It would be awesome

[@DarkAttack14]

This is a cool motor but it would not be more appealing than ecoboost. I hate ford but those turbo motors they put out lately put down some solid power and have a lot of tuning headroom

[@pweller3960]

Just to say Daimler did an all aluminium V8 2.4L 60 years ago for their Daimler dart.

[@BryanTaylor-hb7qr]

Think the Daimler had a cast iron block and alloy heads. Rover had an all alloy engine based on the Olds engine

[@jstdrv]

the daimler was a 2.5 liter with iron block and hemi heads. A friend of mine has a prototype TVR Vixen from the 60s with that engine

[@darryljosephsmith2725]

This is my project car and I want to use it to show off the quality and awesome engines that can fit into a volvo 245dl and represent the BRZ Synergy V8 2.4l engine.

[@Petriefied0246]

Doesn't variable valve timing mitigate the low end torque issues? That would be an excellent thing to integrate into an engine like that for the road.

[@borla4491]

Better than just making another Turbocharged V6. Besides, I've been saying this for a while.....why not just make/create Smaller Block V8s if fuel efficiency and performance is a concern? Along with Turbochargers and Superchargers being options.

[@laurean5998]

Because a v8 with the same displacement will always have much more combustion chamber surface area, which means more heat is lost and efficiency is worse, there are more frictional losses as well.

[@borla4491]

@@laurean5998 I don't see much difference.

[@borla4491]

@@laurean5998 And besides, Lexus LS Sedans has the V8 4.0 liters, and some of McLaren's vehicles has V8s of 3.8 liters.

Hey cool video thanks for sharing cool motor was wondering what's all out there for small displacement V8s I just bought a Range Rover with a 3.5 liter GM Fireball

[@goncaloalmeida347]

Incredible Engine 💪

[@ChePennyDK]

Would love to build this, just with Harley Davidson cylinder heads!

[@chrishenniker5944]

That’ll be awesome, if it’s going to have a Crossplane crank. If it’s got the cylinder heads, barrels, valve train, connecting rods and pistons, all you need is the block, crank, cam to make.

[@LNVACVAC]

Dreaming with a Factory 5 Cobra with one of these.

[@pieceofshot-ur]

I have an idea for a video you could make. You could talk about other engines made my other manufacturers that have the same basic recipe as the 2jz which are : aluminium head, iron block, six cylinders, turbo charged and other. I think this would be an interesting topic because as we all know the 2jz is increasingly becoming more expensive and difficult to acquire so some light can be shed on some other great engines. A great example would be the mercedes OM606(which is a diesel but a great engine nonetheless) . Another is a six cylinder engine made by Volvo, I've heard it's called the 2j - swede. What do you think of this?

[@leecline5759]

I6s are for losers. 1UZ life

[@piuthemagicman]

Yes Volvo B6304, B6284T and B6254. B for benzin, 6 cylinder, 3,0/2,8/2,5 liter, 4 valve, T for turbo. But! It's a modular family with 5 and 4 cylinder versions too. There is a 1000hp 4cyl modular volvo engine here in Finland; S40 with a B4204t. Extremely capable engines.

[@rickcupola6262]

Ford Barra, Nissan RB series, Toyota JZ are all iron block aluminum head inline sixes.

[@cj09beira]

another if you want to say in toyota is the 1FZ engine, a 4.5 litter inline 6 made for land cruisers

[@ndlovulwazi]

this engine would be perfect for WEC hypercar, especially if it's pared with a hybrid system

[@chorumebodykits5218]

thank you very much for the information, I'm from Brazil and I had already seen Jun a while ago. I'm wanting to do it with m50 bmw

[@coreyrussell2942]

I have a engine suggestion. The Mercury SB7. A LS7 based engine with DOHC. Dope as hell.

[@benwhittle7204]

Do you have Synergy Auto's website? Googling seems to bring up a lot of unrelated companies.

[@TheRandalHandle]

Everyone seems to love the 4BT Cummins, or at least they used to

[@kizunaaiartificialintellig5155]

i know it's a Honda engine but still sounds like it were a 4 cilinder, I am sure that the sequence is the same as if it were a 4 cylinder bcuz if it had the sequence of a V8 it would sound very different

[@urgandma]

A V8 doesn't have a sequence, you're taking about the difference between flat/crossplane crank. Yamaha has their crossplane inline 4 sounds like half an American v8

[@MickH60]

Kawasaki...

[@chrishenniker5944]

The Daimler Hemi is only 100cc bigger than this, but Honda does a five litre small block.

[@deborahchesser7375]

A small v8 that loves to rev, I see no problems here.

[@godzuki2099]

Wouldn't it be easier to stick together two v4 rather than two l4? I honestly would like to see a 1.2l V8 from 2x 600cc bike engines, maybe stroked for torque though...

[@tlovsoe4211]

no I4 has the correct barrels and heads you can even slim the rods down and reuse the crank

[@adamham6705]

Judd v8,v10 race engines......sound so cool and make alot of hp.

[@chorumebodykits5218]

This question of the opposite heads I kept thinking thousands of times

[@Kneedragon1962]

Love it! I don't know about a zx12 ~ I know I owned a zx14 for a couple of years, and I've often thought of doing exactly this with two zx14s. ~ 2.8 litres, about 400 hp, and torque is a little bit scarce below perhaps 3,ooo but once you get to that, it goes all the way to 12. It's got an awful lot more bottom end & midrange than a zx10r. Could you drive a small / mid-size car perfectly fine with a zx14? Hell yeah! So how would it go with 2 of them? [evil laugh] Let's find out! Imagine something like an Opel Cadet, or a Datson 1200, or a Mazda 808, but with a 400hp V8 in it, which weighed more or less exactly what the original motor weighed. You'd need a slippery diff, (The hell with it! Throw a spool in there. Who cares?) and .... a friend on the local police force ~

[@NidoKhalid]

Kinda wish this thing revved to 21000 RPM like old F1 V8s

[@Eeen_Engineer]

Excitement and then heard the sound… 😢

[@zAvAvAz]

It's the same as an F1 engine used from 2007 to 2013

[@manitoublack]

While interesting. I'd call Judd for their 3.0L V8 any day of the week first. Race proven for over 20 years. But still well outside my budget.

[@MickH60]

Why would you think Judd is the only company capable of making these engines ? , this is established tech and company and has been around for a while....

[@alexjenner1108]

The newer BMW S1000RR based Synergy 2.0 L V8 appears to be higher revving than the Kawasaki ZX12R based one and holds several land speed several records at Bonneville, e.g. class G/FCC for a production based 2.0 L naturally aspirated car. kzbin.info/www/bejne/l2jboo2YfKZmrJY

@hanlee2894 are there benefits to high redlining? i see enthusiasts talk about it all the time

[@hanlee2894]

Higher revving engines generally gives wider power band. more top speed at high end generally, while sacrificing low end torque. Me, I just like the sound of higher revving engines more. I like the higher pitch motorbike / f1 sound vs compared to the cross plane American rumblers.
