Oh that's sweet. Is the supercharger belt driven between the carb and crankcase?? Any more pics?
Wonder why they didn't go ''full tilt boogy'' with over head cams?? Pushrods are ''old tech.....'' (But I still love it!)

I wonder how they did the oil system! Overhead cams would have added complications in this area also.
Interesting engine and I'm sure a sign of whats to come in the future. I wonder if the clone will be out before the original hits the market?!

Ha!! If that were me, the engine would ride in the front seat and the "old lady" in the back! Hmmm..... maybe that's why I'm divorced....
Anyway, with the cam and supercharger belt driven like that, it seems like doing over head cams wouldn't have been that big a deal. Maybe even less machine work and parts?
Cool supercharger. Looks like a "Roots" design. Can't wait till someone reviews it. I hope it is one of the reviewers that takes it all apart and shows the goodies inside...

If push rods are mounted on camshaft center line and actuated by lobes, how does this engine work? The push rods are mounted near the top of that box with the "USA" plate. I can't see lobes and lifters being under there. Not enough room.

Looks like it could use a couple idlers on those belts?

I sold the engine to a German collector.

Interesting to say the least! Would love to see a review, any idea when?
('Super Charged Twin' would be more accurate, nitpicky I know. I thought I'd get to see twin SC's. ) [X(] Now that would be nice!

wow, I didnt think our newsletter traveled much further outside our club but I guess it did. I was the one who took that first picture. I just got back from Joe Nall a day ago. I tell you what, the cnc machining and finish work on this engine was absolutely gorgeous. It almost didnt even matter not getting to hear it run, I was just loving the way this engine looked and felt. Dont get me wrong, I still would have loved to hear it run.
