We have a CNC sitting idle as well. The problem is not lack of ideas or things to make, it is lack of people who are able to pay what these items cost plus a meager profit.
The machine is likely to remain underutilized until this depression lifts ...

It has been done (I believe I've seen the prototype with my own eyes) but there is just not enough meat to keep them cool. Plus there is a nightmare of syncing the valves with existing rockers. I believe watercooled 4v heads are the only way to do this.

What is affordable? We make them and are just about finished. The 4340 material for the rears alone is expensive plus material for front hubs plus machining, plus drive pins plus nuts plus brake hats plus rotors.......... there is a lot of cost in making them so I am curious what affordable is. Don't forget you need wheels to go with them.....
Cheers

Replacement front rotors for the floating 78-79 hub design. OEM rotors are too $$$$.
Another sillyer idea is a cruise control module for the 930. a turbo support bracket for the k27 design that actually fits.

Do you think it would be possible using Thermal Barrier Coatings that are available today? I have only seen the 956/962C (water cooled) 4 valve head in a photo. Not sure but from the photo it is shown as a single head, unlike the 959 I can only speculate that while developing the prototype 4 valve heads they found (as you pointed out) that there was not enough meat on to keep them cool. I'm wondering with the TBC that are available today weather it would be possible to control the heat load in a finned head? Design them to use the 959 cam towers, cams, rockers, covers etc.

A set of center lock wheels are going for $6000.00 on ebay right now. Aren't there wheels out there for around $2500.00 or so? |

Don't always assume there is a porsche tax. Something like centerlocks is a limited appeal product made in small production runs. The design, set up, manufacturing, fixtuting etc all needs to be amortized over a small production run.
Is 6K a little much for that product? Probably. Cheers
