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.

Sorry - because of the confidential nature of the 4-valve development attempt, there will be no pictures. If, however, anyone has questions, feel free to call me at 212-628-6778.

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.

Understood. It was for anything else that you can share photos on. Just love to see the new things that are being implemented in your 964. Like that anti-roll bar.

I am just happy to see you continue to share updates on the progress.

Though I will not have pictures for another few weeks, the weight of the new rear anti roll bar (for use with a Tiptronic) is .878 kg or 1.935659 pounds.

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.
