Im looking into a "pop off valve" for my custom supercharger project. Greddy makes one, but their specs are in kg/mm2 and I need to know what that amounts to in psi. The specs are .08 kg/mm2 - 2.0 kg/mm2. Im looking for an adjustable pop off valve that I can adjust the psi down to 5-7 psi. Im still wondering if an external wastegate on my intake tube (with a manual boost controller) would do the trick.

 

just multiply it by 14.2233439

 

This is WRONG!!!

The correct conversion factor is:

1 kilogram-force/square millimeter = 1,422.334,333,428 pound/square inch

 

1 (kg / (mm^2)) = 1 422.33433 pound / (in^2)

Google is one hell of a search engine.
