Model V8 engine electronic fuel injection

[@Keith5700]

I'm afraid it will be a couple of years yet till I test the hp. I'm doing a 1/3rd scale V10 at the moment. When that's done I'm going to make a small dyno and get both engines tested. v10 is a bit more complicated than this. Variable valve timing and built in supercharger.......cheers.

[@DamnDecker]

wha wha? VVT and forced induction? /drools. Are you going for a centrifugal or roots/twin scroll? I am curious though what you (probably) have calculated the efficiency to be, especially due the the smaller mass of moving parts, and the smaller surface area of friction surfaces, compared to conventionally sized motors? You obviously arent doing this just because you are bored. Ha! saw this video when you posted it a year ago, and very interested that you are continuing development.

[@Kavster92]

Just seen the V10 build it looks fab, any hope of a vid anytime soon?

[@Keith5700]

Hi, the V10 won't be finished for at least another 12 months, but I am considering doing a little video of the build up so far. I want to do another V8 video too, just to answer the skeptics who think it's a fake! Cheers

[@Keith5700]

nallen100 You are incorrect. It runs fine on throttle position and rpm, which are all that is required to create the fuelling map. I have run this on full sized engines too. The IAT and O2 sensor then just fine tune the fuelling map. I just set the iat to 30c to get it to run. The engine is a bit small for a full sized o2 sensor.Check out KEITH5700 photobucket later today, I have just taken pics of the tps, will upload later.

[@Keith5700]

Then Megasquirt has a choice of two ways to create the main fuelling map. Either manifold pressure and rpm, or throttle position and rpm. If you create the map using pressure and rpm and then overlay throttle position afterwards, using the data logger function you can see that the lines are virtually identical. If you have used afternarket ecus then you must surely know all this? I have used the Holley Commander and Emerald M3dk too, and they can both run with TPS and rpm. I stand by what I said about the O2 sensor. The narrowband sensors are virtually useless on aftermarket ECU setups. All my full sized engines ran fine without. Wideband sensors are very useful though, but I have only used them for setting up, and not for normal running. My offer is open to any sceptic to come and see the engine running. I am in Derby, in the UK.

[@Keith5700]

Thank you for continued comments. For some reason I seem to have lost the facility to reply to individual comments, for the last month at least. I'm cracking on with the V10 at the moment. Software is Tuner Studio by the way. It comes with the Megasquirt.

[@Towlieee]

megasquirt for the win!

[@TheTalman1]

Oh man please link the build log for the V10 I'm still halfway through your buildlog for this motor and as a young machinist I'm quite enamored with it and wish i had the time and skill to build my own

Absolutely amazing!! Such a beautiful work of mechanical art you've created here and it sounds as good as it looks!

[@RyderSpearmann]

OHMYFREAKINGGOD. For those that don't know... this is a HAND MADE engine... with manual machine tools... no computer controlled anything. Just RAW skill and perseverance. This effort is unimaginable to me, and that's only because I know something about it. My eyes are wet watching this...

[@svpowers]

Awesome machining work, having spent most of my life with engines at an OEM, I certainly appreciate your work.

[@managedsolutions6355]

This is probably the coolest thing that anyone has ever made with a Bridgeport Mill. Well done!

[@thekingofvirginia5014]

This is literally the best thing I've seen in my life!

I like how it runs 10x smoother than any of the carbureted model V8 engines with fixed ignition. Now build a miniature engine dyno and tune it under load!

[@cr4zyw3ld3r]

this is absolutely amazing, and despite being so small it sounds great too. Does it it vibrate or is it fairly well balanced?

[@Keith5700]

Conley engines use spark ignition same as this. They use distributor though, whereas this uses the Megasquirt to control all the ignition system. Cheers.

[@Aristocrafied]

It even sounds great, would be amazing to see in an RC vehicle

[@DYLANTRIES]

Love that your intakes look so much like the tuned port injection GM put on camaros and corvettes in the 80s and 90s

[@Alexandra-Rex]

This is bloody awesome! But I'm a bit sad that you didn't let us hear the proper sound, just for a few seconds even :P

[@karmatose]

This is absolutely spectacular. I'd love to hear this thing roar without the mufflers on it. Work of art, man. Work of art.

[@RemetinecBoys]

still it sounds powerful!

[@Keith5700]

My last full sized car had a 383 Chevy with tip manifold and it looked really good, so I wanted it on the model. Intake pipes were the hardest part to make tho on a manual mill!

[@stevehuckss396]

Hello Keith! As I read the comments I am amazed at some of them. It's this, it's that, it's not real. holy cow. One comment I saw was that Gary Conley cant get one to run on injection but Keith can, must be fake. Well I have met Gary Conley and I have to believe that if Gary wanted his running on injection they would be. He is a very sharp guy with enough smarts. For what ever reason he decided not to do it, probably the cost and time to modify off the shelf parts. That doesn't mean that somebody else "cant". Keith did, get over it. Another comment I saw was that it had to be glow fuel. Makes no sense. The small V8 engines run just as good on gasoline as glow fuel. Yes you have to make tiny spark plugs, big deal. The fact of the matter is that this engine is real and is running as stated. Suck it up and get over it. If you still don't believe it put your game controller down and go to a model engineering show. The show in michigan hosts an entire hockey rink full of them for you to see. Seeing them in person might even prompt you get out in the garage and build something instead of sitting in the house doing nothing but talking bad about somebody else and what they do. As someone who has also built small engines believe me, it's real.

[@Zoomlens]

This is the best miniature V8 I've seen yet - BY FAR! BRAVO!

Keith, this is awesome work. I have read through every page on the Home Model Machinist forum regarding your build and am blown away. For those that haven't seen the build progress, go to homemodelmachinist forum, the project is labeled "1-4-scale-v8-first-project-13548" and read the forum progressing this amazing build. Well done!

[@Psyjuv]

in my baja that would be so sweet

[@Keith5700]

The injector sits in the vee of the block. It's fastened to the base of the inlet manifold and squirts upwards onto a spray bar at the top of the manifold. Then it gets sucked back down into 8 channels in the inlet.

[@DownhillRiderBG]

more torque than a honda

[@zero00tolerance]

I have a Honda been using it for 10 years now without broken down anything.. while my friends with other brand name cars often break down each year. I love Honda man it saved myself so much money.

[@MrRexquando]

Who would spend 3 years building this and only shoot one short video? Hmm..

[@MrRexquando]

Rob Torresan I have seen the build blog. Dozens of missing steps etc. Have you seen it? I saw how it wouldn't run with a carburetor then magically it runs with fuel injection? Raises more than a little suspicion. Gary Conley makes mini v8s for his business and he can't make "tiny" fuel injection work but Keith on his first engine build in his life makes it all come together? Glow fuel V8s (schillings plans) are all over the internet. That's what I think this is. But it looks great so keep the fucking snide remarks to yourself :o)

[@MrRexquando]

Wow, totally amazing! The engine is smaller than the coil pack or ECM! I can only dream about having time to make something like this. Thanks for sharing it. I am blown away!

[@RK1FX]

lmao thats a small Coyote 5.0 lolololololol

[@Keith5700]

Yes, one day, but the problem with selling it now would be that I would have to make it portable, which means packaging all the cooling system, ignition, ecu, etc into a nice neat unit. I'll do it one day, but I can't spare the time at the moment. Cheers.

[@Keith5700]

There is a bit of vibration at high revs, as you'd expect, but bearing in mind it's bolted rigidly to the bench there's a lot less than I thought there would be.

[@Keith5700]

About 2200rpm I guess. The flywheel is made from Tungsten alloy so it will idle lower, around 1400, but doesn't sound as good.

[@GyroPyro121212]

Without a doubt, the most beautiful, brilliant, and advanced miniature engine ever built.

[@Keith5700]

The program is called Tuner Studio. It came with the Megasquirt. Very user friendly.

[@Keith5700]

I've no idea how much power this thing will put out. Not much at a guess! I'm planning on making a small dyno for the next engine. I just wanted to see if I could make a working engine. Now I know I can I'm now going to make a high performance v10 and then give it some proper work to do. I quite fancy twin turbos too!

[@micky2900]

That is ORSOM, steady idle no vibration very good engineering.

[@twinturbocoyoteftw]

Insane!!! The hours it took to make this work it's an amazing feat!!! Genius!!!

+Greg Campbell there was some controversy a while ago when people started thinking the engine was just a plastic moulded kit, and I'd dubbed the sound on afterwards. My second video seems to have silenced the disbelievers.

Woah, and it runs so smooth too. Lovely!

Hi Keith. Absolutely astounding feat of engineering! Are you planning on doing a write up of how you built it/made components? Would love to know more about this. Are you planning on showing it anywhere?

[@Keith5700]

This runs on regular gas. Model car type fuel is for glow plug engines.

[@NicksStuff]

That tiny alternator is so cute!

[@mac1mike]

Love Megasquirt, love this and mucho respect!

[@PistonAvatarGuy]

No, it wasn't based off of a small block. Any kind of OHC engine needs to have a block designed to suit the cam drive. Designing and engineering is EVERYTHING that makes an engine what it is!

[@dzelpwr]

You know what production engine this reminds me of? The 1990s Corvette ZR1. Only time Chevy put a dual overhead cam, 4 valve per cylinder engine in the Corvette. The intake manifold is very reminiscent of the LT1 and ZR1 of the time period from what I recall.

[@nlanfran1]

as a ballpark, a 50cc single cylinder honda engine puts out 2.0ft-lbs. Assuming this engine is a bit less efficient due to the increased number of parts and lack of optimization (sorry Keith, not hating!), I'd guesstimate it just above the 1.0ft-lb mark. Amazing engine Keith, let's see what it can do on a dyno!

[@givemetoast]

That’s simply amazing! I think the GM Tune Port intake would be a great combination with the overhead cam engine like was done here!!!

[@kwaaaa]

Sure thing Mr. WetBlanket. This man is showcasing his amazing talent and skills, not trying to revolutionize the world or something (that's a job for world-changing youtube commenters like you, of course).

[@Keith5700]

Hi, not really solved, just piped the exhaust up out the shed! It's a piston ring issue, but should be easy to sort for next time.
