New Air Cooled Engine

New Air Cooled Engine
I must apologize to this Forum. While I have posted on the 964 Forum and the 993 Forum about the now approximately 10 month old effort to produce two new normally aspirated, air cooled, 4-liter engines, a 2-valve and a 4-valve, I have not posted here. I will, if anyone is interested, post here from now on too.
Latest Updates:
2-Valve
Engine completed first round of dyno testing – 450 HP and 452 Nm Torque on street gasoline and with a catalytic converter (expect a few more HP from final 2-valve engine).
Next Steps (already begun):
1. Evaluation of Engine after initial dynoing.
2. Determination of parts (existing, new and/or modified) to be used for Endurance Dyno Runs.
3. Sourcing of modified and new parts.
4. Tooling for Cylinder Head Gaskets
5. Development and construction of Prototype Induction System for 2-valve.
6. Development and construction of Prototype Fuel Supply System including Throttle Actuator including Retainer.
7. Development and construction of Electronic-gas Adjuster and Retainer.
8. Development and construction of Exhaust System and Catalytic Converter.
9. Development and construction of new Test Bench and Engine Wiring Harnesses.
10. Development of new Bosch Ms 6.2 ECU and upgrades.
11. Development and construction of Prototype Oil Tank.
12. Endurance Dyno Testing.
Assuming success:
1. Production of throttle bodies in a lighter weight material, gold plated to keep cooler.
2. Production of stacks in carbon fiber, gold plated to keep cooler.
3. Production of new oil tank in carbon fiber.
4. Production of air box, gold plated to keep cooler.
4-Valve
Engineers in three countries working.
Engine will be 4-cam
Engine expected to produce in excess of 500 HP.

would love to see and hear about progress
hope at the end of the day it becomes enough of a 'product' that others with 993/964 cars might be able to commission one at an obtainable cost

I've also been following the progress in the 964 forum for some years now. I hope you'll take it for a cross-country spin sometime -- maybe to park it at BMWs CF facility in eastern Washington...

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+.

This may sound silly, but would there be a lower HP version of the 2 valve that would provide a longer lifespan?
