*IMPORTANT CORRECTION:* In this video I state the boost pressures are 1300-1650 mbar *above atmospheric,* as is indicated on IndyCar's website (bit.ly/2XvviEU). This information, and the website, are not correct. Two IndyCar engineers have since notified me the boost pressures are absolute, meaning the gauge pressure for these engines above atmospheric is about 300-650 mbar, or about 4-9.5 psi. This is *significantly* less boost than discussed in the video. The math makes sense as well with the update. With pressure ranging from 1300 to 1650 mbar, and power ranging from 550 to 700 HP, we can do some quick ratios to see if it adds up. 1650/1300 = 1.27. 700/550 = 1.27. The power gain is thus proportional to the gain in pressure. E85 plays a larger role in power generation than the video indicates, and makes up for the gap that the "reduced" boost makes. Apologies for providing incorrect information, and thank you to the engineers who reached out with corrections and supporting materials! Mistakes happen; I will always do my best to provide corrections if necessary! Hopefully IndyCar will correct their website as well to reduce future confusion.

Would you ever consider doing a video about the upper limits for an engine's RPM? I know F1 cars have had some crazy fast turning engines in the past, and when I calculate the time the combustion cycle has to produce power I get a surprising small number. Which leads to my question. Is flame propagation the limiting factor, or something else? And if so what is that limit (in time and rpm)? Thanks

Now I I know how power relates to torque

It's not difficult to get the type r a bit more power

As soon as I saw 12000 rpm I just thought to myself that you have a factor of two there straight away. I think the cam profiles will be pretty wild in the race car and the peak power band extremely narrow, none of which is desirable in a road car!

Turbo powered engines worn out quickly as older normal engines

Honda motors are way underestimated. These motor have bin dynoed over 1000 hp to the wheels on Honda 2000S.

Does changing boost increase put more strain and wear and tear on these twin turbo V6s? Also is the Indy motor a DOHC?

How does honda make 700 whp out of a 2.2? Intresting question Jason. How does honda make 700whp out a 2.2TT? Well Jason, with boost you absolute pillock. Just because they both see ~23 psi above atmospheric pressure you still need to know how big the turbo is, a bigger turbo pushes more air at a given boost pressure. Turbos aren't measured in boost, they are measured in CFM. A smaller turbo is going to spool faster and be more effcient at lower pressures, while a mid sized turbo will have response and a broader range of effciency, while a large turbo won't be efficient at low boost, but will be an absolute minger at higher pressures, of course with added lag and higher boost threshold.

Very well explained.

Piston speed in MPH??? WTF? How about mm/sec?

ICE vehicles are now over the hill, they will be laughable in the next decade. Electrics will rule the world.

Imagine putting two k20 side by side and you obtain a 4.0l v8 and you put twin turbo in it you beat the mclaren ass with same setup

Can I put this in my Honda fit

Easier explanation: Power = torque x rpm Since the civic only revs half as high it has half the power as the Indycar.

@Engineering Explained. Can you please talk about why Laser ignition never made it to mass production?

Another plausible reason for the greater horsepower in the V6 vs the I4 is the head design and valve size. In a NA engine heads are where the HP is.

Honda has 1.5 litre V6 TwinTurbo that kicks out 1,500 hp

I wish honda would offer more performance on the si and type r and their suv

The ultimate Honda engine would be a V8 Short block 4.8L... but the heads are actually 2 K20a Type R Heads.

I didn’t understand a damn thing he said! You made it sound so boring like you dude. K.i.s.s.

Seeing the K20C1 compared to the Indy engine is awesome! ..... now where can I buy that Indy engine to put in my car? It probably cost more than a house though lol.

How often is the engine rebuilt? if you wanted 2000 miles then fuel+air=power for any engine design. if there is no concern for consumption or durability then I dont understand the fascination.

Love this channel and how in-depth he gets

Will they sell it so I can do an engine swap with it?

I know you’re a very smart man Jason, so I ask you.. do you know of a Dr.professor Patrick?

And my 3.6L sucks gas and makes 128 hps America makes the best garbage

Yap yap yap....

Why is boost directly compared? Doesn't cfm make the difference when in comes to making power? 6 psi is 6 psi. But at what cfm?

Exactly, total volume of air in race engine is about 2x of the street engine

Curious about the weight difference and Intercooling if any

type r engine cover looks cheap

F1 honda produces 900+ hrpsrs at 1.6l v6 at 13500rpm

700hp and no torque 🤣😂🤣

I guys i teamed up with honda :) big flex

You compare either of these engines to an old k series with a turbo slapped on it the power is slackin lol

Awesome... I feel more stupider now..

We should need to see how the k20 would do with stock boost, but free intake and straight exhaust, and revised fuel and ignition advance. Then it would be both "off-street" spec. And same fuel (with corrected ignition)

Ur hello everyone feels like another youtube channel daily dose of internet

So there is replacement for displacement

They make a big my take by letting this guy walk into their pit. He's gotta leak all their stats.

Honda has a 700 horsepower 2.0 liter turbo in GT500 in super GT too

If you had the tools ,to build a virtual engine with all its components, you will be able to find all those numbers,real torque, real peak hp,real boost and everything else.

Speed makes horsepower. The end.

Vtec kicked in

Would this fit in your Miata? :D

So is this to say that if you were able to get the I4 to run at 12,000 RPM, and used racing fuel that it would be able to produce nearly 700 horsepower?

I got to 6 cylinders twin turbo and 1200RPM and felt I didn't need to know more to understand why it makes so much more power!

That's why longer Rod's are in diesel engines and have low rpms for quick shifts for pulling cars with short Rod's have high rpms and are made for speed

Wish the civic would come with power like that

You forgot to mention that boost is a measurement of restrictions

With an avg piston speed at 20.7m/s, they can say the engine is only designed to do 2500 miles, but really it should be able to do a lot more. I suppose this is likely due to running a tiny overall coolant and oil volume through the block to improve packaging and weight.

With the valves and crank operating that fast, it would be hard to make 1.6 bar boost from just 2.2l of expanded gases.

This v6 + (700hp & 12k rpm) + 3 electric motors =best nsx of all time. Seriously if honda want to he can make the fastest super car ever

As a proud f1 fan, i gotta say, those cars make about 900hp from a 1.6l V6T so we win, plus 160hp from electric motors

Honda's current F1 engine makes over 1000bhp from 1.6L V6

The Civic engine is actually used in a number of junior formula cars, as well as the Fit engine in the F1600. (Think of a replacement for Formula Ford)

They should put this in the accord and Ridgeline

The short answer is [ A C T I V A T E T H E H O N D A - B E A T ]

too technical. it's fitted with a large turbo, hi compression, large valves, short stroke, free flowing exhaust. it took 60 seconds to write this and probably only 10 to read it. solved.

แรงฉิบอ๋าย แรงแบบหูตาแตก

Australian commentator for Indy car racing? Fair dinkum! 😂

Interesting take, but why focus on Honda? Both Chevy and Honda supply engines and the make virtually identical power. Give some credit to our boys! And anyway the F1 cars have FAR more advanced technology than Indy. They are smaller, higher revving, more powerful AND more reliable and more fuel efficient. Talk about THEM!

Looking good, Jason!

I love you F20C K20A2 K24 🔥🔥🔥

Engineering for nerds.

One has a warranty, the other?

So basically boring your engine, tuning it for e85, making it sustain 12 000rpm and higher com ratio would get you about 700hp

Unreal...a two seater Indy car lol.. Jason holds up!!!

Another great vid! Would love to see you build an engine within Automation - Car Company Tycoon !!

But it has a lifespan of what? Cant make a engine that stressed out and not expect it to wear out fast too.

i mean you can get 205 HP out of a 1L engine that's N/A so its really not that surprising, still even though not surprising doesn't make it any less interesting or well designed

You know he was driving slowly right? 😂

Put this in the Talon side-by-side. Okay, something like it. Some manufacture quit thinking that all you can run is 1000 cc motor.

I already know,,, it's turbo charged and double the rpm,,,

What is the calculation you used to know the stroke length?

Put it on a motorcycle

you missed turbo sizes. would be nice to know the comparison

It has a similar power ratio with the koeniggsegg gemera with 3 cylinder, 2.0l and 600hp

Honestly, any manufacturer that is still using a cam shaft for high output internal combustion engines is obtuse. Koeingzggzzggh has showed us how a valve system should have been right from the start. It is a shame that large manufacturers did not invest into this and it took an ambitious small company to do it. Honda, hayabusa, cosworth= backwards old trash.

how do you go a to b in no time at all corona virus

I need this engine to my fn2 🤔

How bout one is a v6 and the other is a 4 banger , reason why one has a single turbo vs twin turbo. Dah

My k will make well over 300 at 8 psi on pump gas. Dont forget about emission restrictions that are put in place on the type r motor.

Why is Honda allergic to V8's?

Soo cool

This engine sooo should be in a NSX

How does it compare to Koenigsegg's 2L 3 cylinder engine? 🤔

I'm more interested to know how the F1 engines were getting 1500 HP out of 1.5 Litre in around 1986. That would be a much more interesting investigation

Turbo chargers and the fact that the engine and turbos explode after 4 laps.

Those numbers are okkkk, but do the 80s BMW F1 turbo engine. That was a true monster and a hell of a story.

Gp2 engine Gp2😂😂😂😂

Plenty of civics pushing over 700hp though. Credit to the tuner scene

If every Honda had one of these I would have respect. But a 4 cylinder lawnmower isn’t cool at all.

Genius! pair this with a VTec trans, you got a sleeper! This just made the Gamera and the Jesko utterly obsolete with its respectable 3 liter 600 HP

It uses a 2 liter 3 cilinder engine.....

Man I should start a NOlocal channel. Seems like everyone is just blowing up from making vids, getting invited to drive indicars for explaining stuff...

We NEED this engine! I’m sure most fellow Honda fans would agree.

Not such a big deal when you consider that a K24 turbo puts out 1,000 hp

700 hp? Easy. Gullible motor mouth journalists.Lots of noise 700db. Stickers, lots of stickers that send a subliminal message at high speed and noise level that says buy me. Your gut will go, your acne will disappear and this chick magnet works.

I just want hear the sound

Hi Jason, great content as usual. Just an observation as we surf around the semi nude Type R engine, the casting metallurgy and fastener coatings don't seem to be what they were in the 90's. I had some direct experience auditing Hex Chrome out of usage for another Japanese OEM some years back. Smart engineering of course is meeting output targets at the most cost effective means, but has the headroom for personal further HP development been diminished (compared to B series) as I suspect for most newer released products? (e.g. LS series)

"Jesse, don't. He's probably got a $100 000 under the hood of that car"

Koenigsegg three cylinder is better...
