Cool, thanks!
Never knew a 4 valve aircooled head with aircooled cylinders was made

Regards,
Walter

Walter, you might want to take another look. It looks like watercooled heads with aircooled cylinders... or was that what you were trying to type :agree:

I've seen the later total watercooled 4 valve heads with cylinders in one..

cool stuff!

As well as a new look on the Home page



Enjoy!

New heads

Hi Guy's
I thought these heads would bolt directly onto a type 4 engine. Will it be this way or will we have to purchase pistons,sleeves and heads as a set.

No, the development of the cylinders is totally separated from the heads.
Its was also (amongst other reasons) an opportunity to see how our selected aluminium casting company would produce something with as close a finnage as possible since there are limitations with sand casting.
We (and the casting company) had our worries with the cylinder mold, but the very first result is already better than I (and we) expected and that is also very good news for when the final mold for the Apfelbeck head is finished and is the reason we were very exited about the cylinder result

Best regards,
Walter

Great idea to do a 98mm cylinder, similar to those done back in the day by ottinger (sp?), but to encapsulate the head studs to provide additional rigidity, especially if you get the desire to put a turbo on there. The only thing I will be curious to see is how well they cool, since we actually de-encapsulated the head studs on all our 930 cylinders to provide better and more even cooling. It was only with the 993 (3.6,3.8) that they absolutely have to be encapsulated, as there just isn't enough meat to seal them off otherwise. Are you going to go one step futher and flame ring the cylinders and heads, to ensure proper sealing. One could easily use some from 3.4 cylinders and adapt them to work. They would be overkill with the registers you've used :-)

Hi Charles,
What do you mean by a 'flame ring'?
If you refer to the late 964 and 993 cylinder-head seal that is embedded into the top of the cylinder wall, then the answer is yes, but not the same ring/material will be used .
Also the cylinders may probably not be Nikasil coated, but with a substance of even less friction, at least as hard as nikasil and lower cost (for our 4 seperate cylinders at least). Its a bit experimental, so I/we can't say/know much more about it yet, but we love this kind of thing and it will be fun to see if it works.

Regards,
Walter

A week ago we gave a presentation of our Apfelbeck Project at an Autodesk Inventor User Group meeting. For this event we played with the new Inventor Studio to create a new movie. Needles to say that movie can be found on our site www.apfelbeck.nl

A small preview:

If you have them cast, why not use alusil and then have the pistons cast-iron plated? As far as flame ringing, there are a multitude of aftermarket designs where the cylinder and head have a ring groove machined into both and the ring actual interfaces with both surfaces. Some are an actual groove whereas other are a ledge (which leaves the top surface thicker at the failure point).

I've been reading all about this project and I'm happy to see the consistent updates and discussions. Great work so far! I can't wait to see phase five.

I hope to see a write-up of each individual test car when the time comes, especially the 4wd autocross bug.
