This is the coolest thing I've ever seen! Great work!

Have had nothing to do with the Singer engine. As far as my own 4-valve air cooled engine goes, I have stopped work on it because I am too busy on other things. Also, I am trying to determine if anyone else is actually interested in buying such an engine or is it just for my own car.

After a long hiatus to attend to other matters, everyone is back on the 4 valve engine project -- engineers in three countries are hard at work. Also, the rear anti roll bar in carbon fiber and titanium has been completed as well as a way to use equal length headers and have heat in a 964.

Bob,
I stopped by a few weeks back and saw the work being done. Would love to see the R when all is settled. Best luck with the engine project.

Robert,
When I was doing my extensive exhaust development on the M64 engine, I never achieved the best results with equal length headers in regards to horsepower. Equal length gave a small percentage bump in torque between 4-4400rpm, but lost hp above 6000. I always achieved the best torque curve with 2 long primaries, 2 mid length, and 2 short.
