:eek:

That's a stunningly beautiful piece of industrial art. Thanks.

"Max power (est.): 526 hp@ 10700 rpm (bmep: 14,6 bar ; 211 psi), dimensioned for Tri-Turbo 1005 hp" from a 2.7L! Would love to hear it run.

For a MS thesis project, someone has a deep pockets or really good finding.

Now that I would put in the back of a 911.

Not sure it would fit.

Nontheless, wow.

Stunning! I'd love to see how it actually works.

I'd love to hear it run, nine cylinders must make some kind of music as they pass through 8k looking for 10k.

+1

I used to own a 5 cylinder MB 300D.

To this day, if there is a 5 cyl. MB within a half mile, I can pick it out.

I'd imagine that a 9 cyl. engine would have a similarly distinct sound.

Interesting engine.
With the 60-0-60 layout, it seems the firing order is not evenly spaced.
That is 6 of the cylinders would fire 240 crankshaft degrees apart, the outside cylinders. The 3 center cylinders would fire between every two outside cylinders, giving an uneven pulse.
That is, said another way, at 0, 60, 120, 240, 300, 360 480, 540 & 600 crankshaft degrees.
One outside bank firing at 0, 240 & 480 degrees.
The other outside bank firing at 120, 360 & 600 degrees.
The center bank interspersed at 60, 300 & 540 degrees.
Leaving gaps at 180, 420 & 660 degrees.
Am I missing something?

I want to hear it run... sure looks nice.

The guy is from Luleå. That explains it. Too much snow and too little to do. :D :D

speaking of which , whatever happend to Project Lumina??

Mattias became father so he wanted to get rid of the car. I just bought a flat so I didn't have the time to finish it. I still have some bits and parts over so I just need to settle down before diving into car project again.

3/8ths of a radial engine.

Janus, that is too cool! That kid must have some deep pockets or access to some serious equipment. I have to think it was heavily funded by an auto maker.

It got me wondering and thinking about other W engines. Here is one from VW. Some of you may have seen it. It is in production. Here is the site: www.seriouswheels.com/cars/top-VW-W12-Roadster.htm

a W12! Janus thanks agian for making me wonder!

opps...here is the engine in:

That engine is quite a bit different in that is is a "Double V" engine instead of a "W" engine. Each of what appears to be a bank is in reality a V-6 with only 15 deg. between each bank, with a common head. Interesting layout. And, the article says there's a "Double V" 16 cylinder model as well. The mind boggles.

I've run plenty of 9 cylinder engines.

But they were all round.
