Old school with a twist

I'd really be curious as to how it ended up on the dyno, where they actually run it at, and what kind of fuel it ended up using. It is uber wicked.

Personally, it is my absolute favorite of all your builds.

Thank you

The engine was sold to a race team in Florida and they haven't responded to my request for information. I'm believe that the car is not complete so the engine is on the back burner.

So Davey, what can I do to help you understand?

Henry:
Where did you chase up the '906' cooling tin? Is it more effective than the regular items?

Is that an instock item at Supertec? I need to order a set of head studs soon anyway.

The cooling tin was designed to fit the 906 cylinders. We believe they promote better cooling. They a made by a US fabrication shop that makes some of our other products.
They come in two sizes. 2.0-2.7 and 3.0-3.5

Well dammit Henry, how'd I miss these? I assume they'll fit Nickies?

Henry,
This is another work of art. I always look forward to your engine build threads. The best combo of engineering expertize and aesthetics I've seen. I always learn something while drooling over the pix.

regards,

Al

Wow, this kind of praise, while perhaps not deserved, is greatly appreciated.
Thanks

Great work Henry, you make us jealous!

Outstandinig!

I have used these 906 thingees of Henry's and they are nice bits that he came up with in those times between finding happiness and working on his rat rod.

Henry:
Did you ever hear anything on this motor? I hurts me to be a pain in the arse to bother you over it since you tried before, but I'm just dying to find out how it worked out.

It always amazes me to see how innovative Porsche engine builders have been over the years.
As expected, Henry @ Supertec built an engine on the cutting edge and still old school.
Cool heads making high compression with flat top pistons.
GT3 Ty rods
Custom crank
906 cylinders with redesigned sealing surface.
906 cooling tin
and on, and on.

Exploring the possibility of building a 964/993 based, Extreme cylinder Head 104x66 engine with flat top pistons and peanut chambers.
We're hoping to save 70grams on the pistons making a 360gram possible.
GT3 Pankl rods, SuperCrank, Peanut chamber heads (Xheads) and super light CP pistons.
Looking for a 9000 rpm, 2 valve, 3.4SS, 911 engine.

That is very cool for your head design.Your thoughts and contributions are very important to us.Thank you for your efforts.Ciao Ciao Fred

[Jeff Alton]

Lets explore this idea more. It seemed to die off with Covid....

Any progress?

Would be an extreme short stroke 3.4, super cool.

Cheers

We used to weld up the old VW heads much the same

[Peter M]

Considering how much money we spend on Mezger engines I'm surprised heads with better chambers isn't a more common modification.

This is how Ducati do their twin plug air cooled two valve heads:


The cutout in the fins is for the cam drive toothed belt and the housing at the top holds the camshaft.
