Thanks! We can only dream of coming close to the video production quality of HP Academy. Super guys over there! Glad that tech content still has a place on youtube, while we try to figure out how to make our content more entertaining also.
I find in interesting how much time and effort you've put into such a oddball of an engine, its amazing what you've been able to get this platform to do.
For optimum power/mass ratio at this power level with a four stroke engine, we think this has to be very close to the optimal layout. Electric and turbines don't stand a chance. Two strokes maybe. With some more hardcore design effort we could probably drop a further 25% off the mass also.
A couple of RUclips "experts" say there are secondary balance issues with inline 4 of this size. Is that a fact and did you do something to overcome that? Good luck, keep up yje great work.
There are always imbalances in every engine. Just depends on how accurately you want to calculate the loads, and their locations. How acceptable the vibrations that result from that depend on the use case. One important thing to note that is often overlooked in "balance" discussions is the power output unevenness. If the forces resulting from balance design are much lower than the forces resulting from power output unevenness, you're not going to gain a lot by focusing on "balance".
@@weatheranddarkness Not so much for racing use where you're using high power most of the time. There can definitely be resonance issues though, this is something that always needs to be taken into account by the team building the car.
@@ElmerRacing Thanks for the reply. I would imagine you might want to keep that sort of data private given the competitive nature of racing anyway. I'll have to be honest, my curiosity towards a dyno sheet stems from a deep curiosity as to how one of these engine would feel like in a drift car. Simulated, of course, but with the way budgets are going in the sport these days, maybe you guys will eventually get a few calls from drift teams, I could imagine that.
Uncharted rpm for the valvetrain, but 650-750hp range would be likely. 11k isn't anything super crazy though, most likely doable with custom cams and springs. (for short periods of time)
"Standard" bosch ev14 type long nose injectors are ideal for keeping port wall wetting as low as possible. Other injectors will work also, just not be as good for cylinder cuts and acceleration enrichment mapping.
I need a 2-cylinder engine under 100kg with the largest possible displacement and a maximum of 5000rpm. Can you estimate the displacement of such an engine to be around +/-300cc
Balancing and layout requirements will have a big influence on the answer to this. Send us over a email and we can figure out how to get started with helping you out!

Yes. We design the head and block to work together. This allows good head gasket sealing. And isn't really possible if just designing the block or the head.
Yes. As we bring up in the video, those big v8's or v6's are only useful if weight isn't important. For circuit racing, and especially high downforce situations weight is extremely important for performance.
Making the engine even smaller would reduce mass further! Problem is that you don't see many circuit racing 1000hp 2l engines with a good powerband. Still a ways to go to be able to get a 2l to 2000hp for circuit racing without making the whole package heavier and more complex than a single stage turbo 4 liter.

This is High Performance Academy stuff, but beyond! Good job, guys.

Well done!
You and David Visard will get on really well.
Keep at it
Awesome comparison!
What you get ,,, when you put the work in ... Well done ...
Fantastic.
Always improving 👍👍
If you stand still while out front, someone will eventually overtake you! :)
@@ElmerRacing Engineer and Philosopher 👏👏 😁😁
Have you ever looked into ceramic coating the exhaust ports in the head to reduce the heat transfer into head?
We can neither confirm nor deny that we have looked into this.
Well done gentlemen!
Very nice Video again!
Thanks for following our videos!

@@ElmerRacing Have you thought about a 8cyl drag racing version of this engine, same heads just a different short block.
Definitely possible. If 3000hp isn't enough :D
@@ElmerRacing Takes a lot of power to get a car to go mid 6s
A lightweight 6000hp engine could make good progress towards that!
Well done 👍👍🔥
Thanks! We love pushing engine performance :)

@ElmerRacing thanks for the reply and insight. Makes sense!
@@ElmerRacingI imagine you would still see a benefit to service life though

What a marvel of engineering. ❤ Is there any dyno info on it?
Most data is from the rp968 teams half shaft torque sensors on track in actual driving conditions.

@OctavChelaru boost response depends mostly on turbo inertia/size. Powerband can always be customized with camshafts and manifolds.
When will a 3.0 liter na version be available for my street Porsche 944? or maybe just the block
Why not just use 4 liter?
impressive engineering for sure, amazing revs for a 98mm Stroke. what sort of engine life are they getting?
Good job
Thanks!
.....would it fit in my Honda?
Yes
Will it fit in my snowmobile?
150kg is really light
@@timothybayliss6680 Yes. If it doesn't fit, your snowmobile is too small :D
In a NA-setup, reving to 11k rpm, what's the output you can get out of the engine?
Uncharted rpm for the valvetrain, but 650-750hp range would be likely.
11k isn't anything super crazy though, most likely doable with custom cams and springs. (for short periods of time)
What in cyl pressure sensors do you guys use?
For continuous in car use, we recommend the optrand type laser reflection sensors.
@@ElmerRacing How about fuel injectors?
"Standard" bosch ev14 type long nose injectors are ideal for keeping port wall wetting as low as possible. Other injectors will work also, just not be as good for cylinder cuts and acceleration enrichment mapping.
Nice! 😎👌
Thanks for the view and comment! :)
2000hp in a track car? It better be a very straight track or have Alonso at the wheel of that thing.
With some good downforce, you can put down 2000hp already at under 200km/h on slicks!
I'm putting this in a Volvo 240 station wagon sleeper 😄
Yes! With some exhaust tuning you might even be able to make it sound stock at idle :D
Awsome😮

You guys producing a gr yaris 3 pot?
Not at the moment. Could be possible though! Is there enough potential in the drivetrain to hold for serious power?
“If you don’t need more than two thousand horsepower”
Nobody NEEDS 2k horses, you get 2k horses bc it’s badass.
If you want to go really fast, you might need a lot of horsepower :D
Can the ac still work in the gtr?
Yes. Our Hel engine is fully compatible with factory nissan accessories for the r35 gtr. Including the ac pump.

All I want to know is; will this fit in my Toyota? 😎
Yes
:D
Did you use FEA software when designing the new head?
Yes. We design the head and block to work together.
This allows good head gasket sealing. And isn't really possible if just designing the block or the head.
Essentially a Honda 4 banger on roids Love it ❤️
Dope crate engine but for that price you can build an American crate engine and car
Yes. As we bring up in the video, those big v8's or v6's are only useful if weight isn't important.
For circuit racing, and especially high downforce situations weight is extremely important for performance.
Why do you need a 4l engine when you can squeze 2k hp out of honda 2l in a smaller package
Making the engine even smaller would reduce mass further!
Problem is that you don't see many circuit racing 1000hp 2l engines with a good powerband. Still a ways to go to be able to get a 2l to 2000hp for circuit racing without making the whole package heavier and more complex than a single stage turbo 4 liter.
Just to entertain the nerds reading the comment section: What would be the (peak) thermal efficiency of this engine?
Unknown at this point. This would need to be measured with a fuel flow meter either on a dyno, or with a driveshaft torque sensor on the track.
