Something a little different, aimed solely at Type 4/914 engines. Project began back in the 1970s and after years of lying dormant, has been resurrected by a team of followers.

very tasty.
Could be a very viable alternative to the Polo flat four.
Looks like it's a long way from functional, with the belts not tensioned, seems it's missing a pulley.
It's crazy how beefy the pulley/belt system looks.
Looks like it will have to have an external oil cooler as there's no room for one in the stock location. The ports there are also blocked so I wonder where they plan to pick it up. Probably will have to be full flow and bypass/externalize the relief piston also.
The shroud will definitely have to be fully custom.
Makes you wonder why they built it for a type 4 vs a type 1. It would seem more at home on a Pauter Type 1 case. I guess it's about application, but the type 4 case seems out of place with all that's bolted onto it, and barely using any of the original design.
God bless people with lots of extra time and money on their hands doing projects that just make you go
That’s an awful lot of extra mass and complexity to get to a 3 valve engine. I’ll be looking forward to dyno development that will be needed to sort out lubrication, reliability, and tuning issues. Wonder what they are expecting for HP output? 2/3 of an equivalent two valve six that has been warmed over?
I see claims of 8500 rpm and up to 115 HP/L - good luck with that.
I prefer to piggyback on all the development that Porsche did rather than reinvent the wheel.

Very cool, budget $$
Where do the alternator and cooling fan mount? The long block appears to be quite wide. I fail to see the point of this endeavor. What is this? A $75k engine?
I love people who do things like this: a stupendous time/money sink that may go nowhere. And if it does, only a handful of people will ever want it enough to pay.
You can just picture them, laying awake thinking endlessly about "...would this work? What about...?"
Just a wonderful example of two of my favotite tag lines:
- Because I can.
- Mine is different
Abso-f-ing-loutely LOVE it.
Chase that passion! Rock on, dudes!
The Polo engines have become very expensive. Like $80-100K when all is said and done. They sort of make sense to me if you want more power in a 356 but a 914 easily fits a six and the Polo engines are only about 80 lbs lighter than a built 2.7.
Do you know the story why Polos are so expensive? Basically someone else kind of stole the design and started building their own instead of Dean
And pretty shitty of them... Only Dean builds Polos. It's his name after all.
@http://www.914world.com/bbs2/index.php?showuser=50 , you can run a 741 but I was heading down the slippery slope of 5 speed and full 911 rear suspension.
Original polo engines are cool (found photos of the one I referenced above….end of my thread jack):

This is a good thread on the Polo engine:

Looks like they are achieving 100 hp per liter - the engine shows dyno numbers of 250 hp at 2.5 l
Doesn't Rod Emory utilize Deans motors in his hi-$ outlaws?

Is that E on the Axe?
this engine was/is under development down here.
3 cylinder air cooled radial. supposed to be 100 hp per litre.
i heard a bit about it a couple of years ago, but not much since.
they were running a test fleet of an old bug and a bus.
also one installed in an outlaw 356.

ground clearance could be a problem?
anyway, looks like it would fit in a 914 engine bay with room to spare.
and its air cooled. or at least one version of it looked air cooled.
i did a bit more snooping around to see if i could find anything further on the radial engine outlaw in aus.
came up with this.
the guy is up in sydney.
notice what else he has in his garage.

interesting. its clear its a serious engine. developed for planes.
might have to find a 914 tub?
i realised the guy doing the visit and making the film clip waved me down last year when i was out in the 914. he and his wife were all over the 914.
turned out to be a nice guy who owns a worked over outlaw 356 which i took a good look over. his car was pretty tasty. there used to be a bunch of these 356 guys met at a cult japanese joint a couple of blocks from me here where the owner has a fairly serious series 1 911 parked in the "restaurant". did a real nice japanese bullet train sandwich but i have not seen them all there for a while. they must have shifted their meeting venue.
