I’d be interested in your headers Fred. You’vr mentioned the mathematical formula based on engine type and using Burns type collectors. Will your headers also be custom to each engine? Sell in pieces or do they come welded as 1 piece?

Ok, so now I read more... you are looking for someone to make your designs...
Longshot: I think the water-cooled guys at Sharkwerks have some of their own designs. I think only water cars-- so likely no competitive situation. I do not think they have their stuff made in house. Not sure about volume. But in the interest of common love for things Porsche, it might make sense to give them a call as part of your networking.

I believe I could donate a GT3 muffler if you’d consider letting me be a header beta tester for my 2.7 RS? I can email you some pics....

Crazy numbers from a 2.8. How many hours would something like this be good for between rebuilds?

life of a 2.8
I took the first one apart at 60 hours.Just replaced rod bearings which looked great.Center main was drilled to feed #2 & 5.Lapped the valves in.Has Ti rods & valves so less stress.Leakdown was excellent and left the rings alone.Has great oil cooling and has heating coupler to warm the oil.Well babied. After its first dyno run engine was taken apart for full inspection because of the build.Only change was to add a dowel pin in the crank for the flywheel.2nd one has never been apart but it is young yet.Fred

If Ole @ WeldingWerks in Orange CA hasn't early retired yet, he has welded many a custom spec header.
