turk turk its been said before but...amazing and tenacious! looking forward for more posts and development pics.

Mark have you had any success with machining parts and any pics to post?

Of interest look at Martin Bott's project at [email protected] A contemporary iteration of the 4 cammer. I believe all new excepting the use of Porsche cylinders

Hey Michel I have not gotten a chance to take any pics of my work on the engine yet and I sure Turk will tell you that I have been promising for sometime now. I did send my case to the machine shop yesterday thanks to my son and with some luck I will pick up my camshafts when I get home and get them assembled so that can be done. I am also experimenting with some the high strength epoxy's for joining my cam towers as opposed to the stress associated with welding stay tuned...

I saw those heads being developed by 5speed and I must admit I am envious and a little sceptical of using 4 valve heads on aircooled heads I keep thinking about heat build-up They would be great as a high revving 2valve design... maybe I should stick to designing heat pumps not cylinder heads

Turk have you gotten any further? I have most of my engine mocked up and I did decide to reconfigure my drive system but still stayed from convential wisdom, I am using the original cam to drive porsche cams at an 1:1 ratio (opposed to driving from crank) now I designing the oilpump that will fit in the void left from back half of camshaft.... as usual when i figure out how to post pictures I will do so soon!

I can't make any atomic weapons, but I might be able to insert a photo ..

To make matters worse I am an engineer with a PHD you would think I could figure out how to post a picture in a forum. I will sit down this weekend and overthink the picture posting thing Razz

Very nice oilpump

Here is a picture of my first mock-up, Now that I understand how to post pictures I will take some better images and post when machining is completed.

And yes you were right it wasn't rocket science just a different procedure from other forums. Look forward to your feedback.

Well, that's only half of the components for a 4-cam pump. It was made by my machinist, who made two when he was presented with the job years ago. Although it's been judged to be of higher quality than the other German-made replacement pump for these engines, the close-knit politics of 4-cam restoration has delegated this one to my display case.

Well it's a very impressive oil pump non the less!
