Moin. Mal a (crazy) question: I intend to abuse an air jet engine (impeller) from the aircraft model building as a turbo replacement in my car. Have a ́97 Opel Astra X16SZR (1,6l 8V 75PS) Who has experimented with it, experiences, opinions, suggestions? Problem underpressure (important because of brake power amplifier): Does the underpressure last when I put a hose in front of the impeller or do you need an extra vacuum pump. cksensor (what a word!) on it. And how long does such an impeller last? It wasn’t designed for continuous operation.
