Still 964 case. So awesome.

I think Robert Linton (GS America guy) is also working on a 4-valve air-cooler motor.

OMG!

Some more pictures of the engine with the chassis above. It looks really interesting! I can't wait to see it come to live.

Yes he has been working on it for some time. I will ask him about it Sunday when I see him. Although IIRC his will be emissions compliant.

It looks like it can propel a submarine. LOL Not sure about the exhaust design and how it will work with the body but I like what looks like a 934 style body treatment. Maybe something different than the standard singer for these?

I guess we now know why Singer has been buying up all the 964 blocks ...impressive on the collaborative effort, would love to know more about the development and details of the motor. That being said, I am more interested in what Robert has in store with his bespoke development.

Is it available as a crate motor?

I don't think singer would ever sell their parts a la carte. It's too bad. I'd give just about anything for that motor

This will be epic. I really like the ram-air intakes into the rear-quarter windows. Very clever design.

I wonder if those are water-cooled heads?

Hans Mezger also in development, awesome

No.

Impressive! Looks very much like a 993 exhaust with pipes replacing the side mufflers. Hopefully some of this will trickle down to us non-Singer customers someday.

EFF. ME.

Can someone comment on the likelihood that a 500 HP engine can be air cooled. In the stock 3.6L cooling load is divided between air and oil. Anyone know the split?

I'm thinking singer is calling this "air cooled" for the hype value and most cooling load is borne by liquid. This is so far removed from the 3.6L, why not just do liquid cooling and ditch the fan?

On another topic, are those heads dual overhead cams? Seems they would be to hit 9000 RPM.

Although its awesome, its also something else entirely.
