917 Replica - Dual 3.0 liter engine -> flat 12

[totle]

Just came across this link.
Seems cool the way they have stuck two 3.0 lites 911 together to get a flat 12

"This 917 is a Melbourne, Australia-built replica. The real 917s have a flat 12 engine. So does this, but the clever part is that it runs two 3 litre 911 engines, one of which is reversed. The two engines face each other clutch to clutch, and the one that is reversed runs backwards! Pretty smart. Together they put out about 500 BHP"


Anyone know how this has been done?
Extended one crankshaft and added a new clutch on the other side ?

Nice replica!

I wonder how they did it?

How do you successfully run a 911 engine backwards?
They must have modified the timing chain tensioners at a minimum not to mention the other hard stuff like...

How do you connect the two cranks?
How do you put a clutch plate on the front of an engine and then bolt up a trans?

The trans is probably a 930 or G50.

I wouldn't mind getting a proper look at this car.

The real 917 had a central power take off gear in the middle of the crankshaft to use the torsional vibrational node there. The dual 911 engine setup would be the same, bolting the two together in the middle with a center gear dropping down to a shaft below the engine, just like the 917. Then the shaft runs back to the transaxle joined by a small clutch (ever see a photo of a real 917 clutch?- The shaft was low so they could only use a small, multi-plate clutch for all that torque!) A Carrera GT ceramic-carbon clutch would be the best upgrade option today.

that has got to be heavy and long!

It can't be that heavy...

If one person can lift one side of it then two should be able to carry it out of the building.
(Damn, I forgot to bring my truck...)

Wow. Just Wow! A thousand HP engine that two guys can carry.

Actually, that one is closer to 600 hp. The turbo versions were the ones that made the big ponies.

A lot of the parts for those engines were magnesium and titanium, so that's where a lot of the weight went.

I can't say. The only guy I have met who'd work on stuff like this is Jerry Woods, and that's not him. I had found that site browsing.

Carl is not in any of those pictures.

[javadog]

I don't think that's Carl. Maybe Gustav Nietsche and Armando De La Rosa.

Ok guys, someone has got to dig up more info on this car. Besides being a pretty damn good replica, the mated 3.0liter engines thing is crazy... the friggin set-up in the pix could easily pass for a flat-12 at least superficially, Surely someone knows more about this car or has more pix of that engine!? Would love to hear the sound of that thing firing up! Seeing those cock-teaser pix is like seeing Megan Fox in a skin-tight nun's habit... u just gotta see more

honestly i have seen enough of megan fox...i am good for now!

this 917 replica is insane and a very, very cool solution to the flat 12!!! i am in love with this car!!!!! we need more info...youtube vids, driving experience info, accuracy of the chassis and body dimension, etc...

WOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Calling all Aussie/Pelican mates - need....more....info!

Andrew and Anthony Keiler, they will be visiting cali very soon

If the chassis is the same guys from Oz, they have an American company licensed to produce the chassis I think:
