Robert -
Awesome stuff.
Out of curiosity - what's the expected life of one of these motors? Will it be something that requires rebuilds similar to a race engine or more of GT3 reliability?
Additionally, with the specialized parts here, what's the serviceability by experienced Porsche mechanics? How about parts availability 5, 10 or 15 years from now?
Thanks!
Kevin

The life expectancy goal for both the 2-valve and the 4-valve engine is the equivalent of a 24 hour LeMans race by a factory professional driver plus some additional hours. In street driving and "amateur racing" this, of course, would be many many miles. After that kind of intense wear, it would, no doubt, require a rebuild of some sort. An experienced Porsche mechanic who could rebuild a GT3 engine would have no problem. The non-standard Porsche parts are made by long established suppliers, most of them already Porsche AG suppliers. As such, I do not expect there to be a long term parts problem. Please feel free to contact me direcrtly,

Good news. Latest dyno run of Cartridge 4 liter, 2-valve, normally aspirated, air cooled engine on street gasoline and with a catalytic converter produced 455 HP and 453 Nm of torque.

Congrats on hitting your benchmark...Great news for you and your team. 2 valve sounds like a thumper...the 4 valve then must be a screamer
