I priced one of those "overflow valves" as Porsche calls them. At $161.00, I'm glad mine is working well! My backup plan was to hide a modern regulator under the car.

It's a spicy meatball for sure!

Interesting, why only 73my(and I assume all the euro mfi)?

And I have a good idea what the WOT/full rpm fuel delivery should be.

Well thank you very much Johnny! It was a fun build and was an relatively easy tune. I am sure you will do brilliantly.

I'll give you anecdote about a 3.2SS build I did. MODS cams 10.5/1 twinplug, Euro ports. Client ran 1.625 headers and some sort of sport muffler. The car was nice but was underwhelming in performance. The power curve was done right around 6000 rpm. The client wanted to step up to the DC60(which I love). I told him if we were to go that route I wanted the Dansk/RSR setup with George's 1.625 headers. I suggested we install these prior to a cam change as I wanted to see how it would run...It turned into a proper beast. power to 7500 after a adjustment to tune for the reduced back pressure. The client was so satisfied that he no longer required the bigger cam. It's an absolute blast to drive! So I have found that once you start getting to the bigger displacement engine, it's almost all exhaust choice that will dictate the character of the engine.
