Another patent is yet more proof that the most hardcore naturally aspirated Porsche will be powered by dinosaur juice.
This patent was for the valvetrain, which Porsche wants to equip with both traditional valve springs and pneumatic valves. A valve spring compresses as the valve opens and decompresses to force the valve closed. It’s a basic system that works, but not at high engine speeds. Porsche wants to include pneumatic valves with lightweight compressed air bellows. The ECU can control the latter much faster, eliminating any chance of valve float when revving out beyond 10,000 rpm.
Pneumatic valves are typically not used in road cars because they don’t need to rev that high. With this system equipped, the next-generation 911 GT3 RS could easily breach 10,000 rpm.
If nothing else, this patent proves that Porsche is working on improving its high-revving engines, which bodes well for the future of the GT3 RS.
