How Honda’s 2.2L Engine Makes Over 700 Horsepower

[@EngineeringExplained]

*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.

[@devilsoffspring5519]

*Very* important correction! :) Thanks for clearing up. It seems obvious to me that the Civic 4-lunger certainly isn't running anywhere near that boost pressure either, certainly not on pump gas at 9.8:1 compression!

[@devilsoffspring5519]

@@jakecole7447 It really runs at well over 20 PSI boost on pump gas at 9.8 CR? Somehow I really doubt it. For 300HP on a 2.0 liter 4, more like less than 10 PSI. 20+ PSI shouldn't be necessary for 300 HP, nowhere near that much.

My suggestion, remake the video where this gets corrected/discussed otherwise we get false data implanted into our brain. That's why this sort of vid is good, we have a stab at how we see things, "experts" pop up and offer valuable info, we all gain. Good job. These question have wizzed though my mind, I'm a curious engineer. I'd like to know the detail of F1 engines compared to a powerful commercial engine. I know octane and revs are the main ones. One comment by an expert was, tolerance are greater (and well defined) on a sports engine, longlevity is not the criteria.

[@patrickbradford6587]

Important correction, the cylinder head flow rate has a HUGE influence on power output. E85 is approximately 105 octane, however doesn't account for the majority of the horse power difference. I would speculate that the cylinder heads on the Indycar engine flow FAR more than the stock type R engine, which contributes to the significant difference in hp, while having similar displacement and boost levels.

[@pelovett]

Nice video. An extremely significant omission was the different induction systems and the number of valves. The race engine has cylinder heads and intake manifold that flow much more air than the street engine. Also, 24 valves instead of 16. Also the exhaust systems are very very different. It's about airflow.

[@hammerhome7879]

12,000 rpm is almost double 7000... higher rpm = more volume/displacement in a set amount of time = more HP

[@PeterXChhanX]

Thats how low displacement engines have to make up for power. It works faster to move the same amount of air as larger displacements. The tradeoff being lifespan but much lighter weight

With 2 additional pistons this makes it easier to build more torque, even though it has the same displacement and shorter stroke than the four cylinder engine.

[@robertjohnson4401]

[@AndrewUnruh]

One thing that was touched on early in the video but not after normalizing for displacement was the effect of the shorter stroke of the Indy engine. Clearly, if two engines have the same displacement but one has a shorter stroke, then the one with the shorter stroke is going to have a greater cross-sectional area. The greater cross sectional area allows for larger valves which in turn allow for greater airflow. Now, greater airflow allows one to combust more fuel which leads to more heat generated which leads to more power - but not at all engine RPMs. If you rev the engine very slowly, there is no pressure gradient to drive more air into the combustion chamber. At very high RPMs, however, on the intake stroke there will be a larger differential between the air on the intake side and after the intake valves. Bigger valves mean less pressure differential which means more air in the cylinder which means more fuel burned etc. etc. In short, the larger valve area of the Indy car allows for higher RPMs without starving the engine for air which allows for more HP.

I think a huge thing a lot of people in the car community or new to it overlook is that Boost is a measurement of restriction to flow. If you can reduce the restriction/increase air flow through the engine by improving the air delivery system, better intake plenum design, head porting , as well as better exhaust management with better flowing manifolds and exhaust. you will make the same or more power at a lower boost level. You are physically flowing more air through the engine even at the lower boost level and it will make more power. I dont know how many times the first question out of someones mouth about a build has been how much boost is it running. When it has no bearing on the power level of a engine. You could have a near stock engine setup with a tune pushing 22-26 PSI and then the same engine platform with a larger turbo & proper supporting intake and exhaust modifications making 150+HP more at 20 PSI

My stock Civic 1.5T is rated for 20psi. I figured out that was absolute when I connected a scan tool and realized it rarely went above atmospheric gauge pressure. I believe most all turbochargers are rated absolute pressure of boost. You have to, otherwise the actual output would vary depending on manifold vacuum and altitude. This is also important as the wastegate is controlled based on manifold vacuum as it’s the total compression ratio of the intake that matters, not absolute pressure to atmosphere.

How does Honda make 700hp from a 2.2L? Jason: does some math Me an intellectual: it has 2 more cylinders

[@BeHappyTo]

it would need to have 4 more for it to make sense

[@BeHappyTo]

@Peder Hansen how does that have to do with anything?

[@BeHappyTo]

@Peder Hansen It is but you can't skip context.

[@BeHappyTo]

@Peder Hansen My point was if the engine had 700hp (about twice as much as the one that it was compared to in the video) then it would need not 50% more but 100% more cylinders, thus 4 extra.

[@Strunz0]

It could have 100 extra cylinders, and with all other variables (displacement, boost, rpm) being equal, it would still move the same amount of air as the 4 cylinder. It's mostly a factor of RPM in this comparison, made possible by the proportion of bore to stroke and maybe some valve sizing, timing and lift, not number of cylinders.

[@mirokefurt4740]

Would be interesting to know what fails after 2,500 miles, or I would guess about 20 hours of race use, or at minimum what the HONDA race mechanics replace in a rebuild, as obviously they do not throw the entire engine away after every race. So what are the weak points ??? Also thanks for the boost pressure correction, I almost thought HONDA defies the laws of thermodynamics using E85.

[@theaman1823]

Another killer video, keep doing what you do

[@michaelarnold4]

something else to consider is the effective area that the combustion pressure can push against. the indy's 95mm bore gives us ~7088 mm2 per cylinder while the type r's 86mm bore gives us ~5808 mm2. the total piston area on the indycar engine is 42,528 mm2 and the type r has 23,232 mm2. theres a difference of ~19296 mm2. The indycar uses its combustion pressure over a shorter stroke as well leading to loads more power.

[@axipixel5811]

Here's one thing he didn't talk about and a little nitpick: Despite him saying the turbos are the same, that is not really true. While they both are maintaining ~20 PSI of boost, this means different things at different RPMs At 12,000 RPM, like he said, there are much more cycles per minute occurring then the Type R engine can achieve. This means vastly more fuel and more air is flowing through the engine. Because of this, the indycar engine turbo is pushing a vastly greater amount of airflow to maintain a pressure of 20 PSI at the intake than the Type R's engine needs to push to maintain 20 PSI at its intake. This is shown in the turbochargers themselves. The CFM of air the indycar turbo can move and compress is extensively greater than that of the Type R turbo. So, while it is correct that both turbos are gated at 20 PSI, to say that the boost is the same is somewhat incorrect. Jason is talking about volts when amps tell the real story of what's happening in these two engines' boost.

[@EngineeringExplained]

I'm not sure you're nitpicking, or that I missed anything. Obviously if you have a higher RPM (more power strokes per minute, as discussed) you have to fill the cylinders up more times, so you'll be pushing more air. Boost is a way to measure how much air the cylinder is getting. The more RPM it has, the more often it does it, thus more power.

[@axipixel5811]

​@@EngineeringExplained Yeah, makes sense. I can see why it's not a nitpick nor anything wrong, but I just felt like it was overlooked and needed mention at least in passing. Thanks for taking the time to read and reply.

[@TheAdatto]

Still same 'boost' but indeed it should be told. More to be learned for people that don't know this

[@boduke9428]

More a difference in pressure and volume isn't it? Kinda how a larger turbo will flow more air at the same pressure than a smaller one. 20psi on a 66mm turbo is less air volume than 20psi on a 77mm turbo. Pressure the same but more air and more power with the larger turbo, assuming no restrictions and enough fuel.

[@mileslange5797]

Thank you for spoon feeding all of us your great and precious knowledge

[@al_in_philly5832]

When comparing the 2.0 L4 to the 2.2 V6 you left out cam design differences between a car which needs to be "streetable" and one which can work within just a small RPM range at the top.

[@QuadDoc]

Jason, another awesome explanation!! Thank you for sharing!! So basically it just breaks down to 1. higher RPM and 2. higher octane fuel?

[@HK_Productions47]

Plus better materials and better craftsmanship probably.

[@jakegarrett8109]

You missed he entire bore stroke... that’s the whole difference. The fuel is fairly minimal, putting e-85 into the street car wouldn’t give you much. You could also run the street car 12k rpm, but the torque at that rpm would fall off a cliff on the Dino run, resulting in probably like 50 HP because the piston speed would be approaching flame propagation speed (which means the force on the piston would be near 0, which means almost no work is done).

[@KennyMarkusa]

It's more than that there is also cam lift timing . duration and cylinder head design that is where the real power is made air in air out more air+ more fuel = bigger boomb

[@QuadDoc]

You guys are correct, air in-out, bore, stoke, materials etc... which breaks down to and results in layman’s terms: higher RPM and higher octane (trying to break it down for someone who doesn’t care as much as we do, lol).

[@rexsong4835]

Turbo sizes are completely different ... different CFM flows. ... 30 psi on a Gt35R and a 30psi on a GT52R are very different

[@corpsie666]

30 psi on the two engines is different independent of which turbo is used to build up that 30 psi.

[@Redsson56]

Your calculations suggestion the F1 pistons have a 10% greater circumference and a 22% greater top surface area. Considering just these dimensions suggest the F1 pistons would be heavier. It’s not obvious a shorter stroke provides a lot of opportunity to make a piston lighter but I’m am sure Honda Engineers did there magic and likely used clever design and likely exotic materials to minimize weight because with the same piston velocity and a 72% higher rpm the pistons will have to accelerate 72% faster and as Issac pointed out F=mA. Honda did an amazing job making this engine work.

In Brazil we actually use e85 on normal cars, cars makers usually advertise power in each fuel and using ethanol it is usually 3% to 5% more than gasoline.
