If you could mix/match any parts...

[Sandman333]

...and magically make them fit/work, including engine control systems, how would you configure the ultimate internal combustion engine? You can separate this into cylinder classes: 4, 6, 8, etc... and any configuration: inline, boxer, V, W etc....

For me, I'd choose a V8, specifically the Ford Coyote block. I'd top it off with these heads: www.coatesengine.com running as high a rod/stroke ratio as I could fit in there on a twin turbo system and VAG engine controller for proven aftermarket programability. Using those heads it might be possible to run 11:1 or higher compression on pump gas, even on a turbo motor. I'd have Bosch or whoever does VW's engine systems develop a combined direct and multiport injection system to keep the intake valves clean.

What would you do?

I think I'd take several older engines (pick your favorite) and only modernize a couple of things... Fuel management and metallurgy/production tolerances.

I could probably safely double the output of my Bug's engine with just those changes while making it live longer. Well OK, I'd use more modern heads (Dual ports didn't start production until '68) and I'd need an oil filter that will screen out more than just boulders and small children.

You could do similarly with a great many engines from the past. I'd love to see what one could do with the Vega Cosworth engine, the powerplant from my old BMW 2002 and a 240Z with those kinds of changes.

I would start with a eight cylinder diesel radial engine, water cool it, then upgrade to DOHC cylinder heads.

[Sandman333]

Lol, I forgot about radial configuration...

I really want to make a diesel VR6.

8 cylinder radial, eh? That's pretty tough to do.

How 'bout a Hemi with a blower in a Prius. With a shaker hood for effect.

[seroki]

How about a 8 cyl boxer Quad turbo (GT45R with the 40R turbine), Midengined, two seater with AWD. Oh and keep it a 6spd

Think a slightly longer Cayman with AWD, 2 more cylinders and a bunch of turbo's

What did you think I was going to do - a six-cylinder, 12 cam, water-cooled, diesel radial?

No one wants that

Everyone knows the six is the embarrassment of the DOHC diesel radial community, and it only exists for people who can't afford the eight.

4-stroke radial engines require an odd number of cylinders

Everyone knows that, that's why this one is a 3-stroke.

I would have gone 2-stroke, but I was too busy dreaming of 16 camshafts.

I figured he already knew that but was simply being... Well, McBanagon.

Like this, see?

You only need 1 F1 engine for the Mini. Duh.

It became pretty clear to me after I quoted his second post that he was joking, but I just felt I'd throw the odd-numbered-cylinders fact out there, since I wasn't sure if that part was a joke or not

Well, there's that and I like to ask questions that I could find the answer to on-line. That way the information is here in the thread for anyone to read. If I simply looked it up for myself, then others wouldn't have the benefit of answers to questions they might not ask. You know, an ongoing discussion.

If there's doubt, it's probably safe to say that McBanagon is having fun at any given time. It's also safe to say he's had me laughing out loud on much more than one occasion.

[McBanagon]

7-cylinder

Well sure, THAT one is.. I haven't made mine yet, so that's the only configuration I could find.

You know, I might be able to make the seven work, but only if I can source one Honda NR750 piston.

Dammit! I nearly shot Dr. Pepper out of my nose!

See folks? This is what I'm talking about. How the hell do you come up with some of these?

[Sandman333]

LMAO now....

Final design:

• Four stroke, seven cylinder radial (less complicated than the three-stroke 8)
• Oval pistons/quatrovalve
• Diesel (plans for future bio-diesel conversion kit)
• DOHC (14 cams in all)
• Quattrovalve
• Water-cooled

Since it's water-cooled, it could be placed anywhere. Mid, rear, front engined layouts are possible (plans for roof-mount are currently being engineered) It can be mounted transversely, longitudinally, or even upside down. The engine will be a perfect candidate for conversions, as the rotation will can be CW or CCW due to the flywheel being mounted on either side of the crankshaft.





RWD, obviously, but it probably won't come to the US.



Still working on trying to figure out how to make the timing chain service simple, since 58 feet of it will stretch enough to require replacing it at every oil change.

epic engine

exhaust-aspirated hepta-turbo setup with three superchargers, right?
