Great thread and I am always interested in streatching the boundaries of what is capable in Air Cooled engines...
Quick question, what does the 6.4 give that the 6.2 didn't for the ECU. Interested in the decision process.

Last week, there was a multiday meeting of engineers involved in the 2- and 4-valve engines.
As to the 2-valve motor:
1. After quite a few hours of dyno running, it was taken apart and showed no wear of any significant type which, frankly, pleasantly surprised all.
2. We have designed a way to supply this engine with or without A/C.
3. Engineers believe they have a way to obtain a bit more than he current 450 HP -- with street gas and with a catalytic converter.
4. Work has begun on Bosch MS 6.4 as the ECU.
5. In short order, we will begin another series of dyno runs with this including endurance runs.
6. During the next runs, we will compare Porsche standard and Turbo fans with a new fan design.
Re the 4-valve:
1. More progress in design.
2. Have established 21 steps that must be completed.
3. Again, Bosch MS 6.4 being integrated.
4. More sophisticated testing being instituted.
5. Though one can never be sure, target HP is 500+.

Normally aspirated or Turbo?
