The car works very well with electronically controlled charge pressure which constantly changes with engine speed and throttle application. This results in cleaner power curves and less strain on the motor. The engine management from MaxxECU constantly monitors the engine, so if a bank runs lean, gets the wrong boost pressure, too little petrol etc. then the system will cut and thus avoid engine damage.
Fresh dyno papers from benching December 2020 are available.

As the car is built on a late G50 911 and twin turbocharged it might be the perfect candidate for a CTR build?
