Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Any engine that will run on 2.32 psi is a pretty well tuned engine,I run a fair amount of engines on my aquarium pump next to my chair in the evening.

So true, with a bigger compressor almost any engine can be made run if you give it enough air, I find any engine that doesn't want to run on my air brush compressor with the built in regulator needs a bit more attention.
