Default Vantage Pro compresssion testing of a rotary engine

I am thinking that using a suitable pressure transducer, probably 500 psi it should be fairly simple to check the compression of a rotary engine. I was just wondering if anyone has done this before? All the rotary engine compression testers I have looked at are quite expensive. Thanks

Why wouldn't a cranking test with an amp probe around the battery cable give you a good idea if one rotor on compression is likely lower than the one next to it

It works just fine. Connect the probe to your compression test gauge without the schrader valve in it and you're all set.

Got one that won't cold start? You already know the answer. Get a new engine.

Or fog it with some nitrous and get one last run out of it. Don't expect much compression after that.
