That is the question. What does crushed and un-crushed mean? I did a search and came up with for sale ads.

 

crushed what? dsm bov?

 

crushed= bov is cruched to hold more boost
uncrushed = not crushed

 

Yes 1st gen dsm. How do you crush? and what do they look like... what is better?

 

uncrushed is good to 20psi if i remember and crushed up to 30. i remember seing a write up about it but dont remember where

 

I think you got those psi #'s wrong.

 

that what i got from a dsmforum i go to. i was in a first gen that the stock one that held to 18 so i figure they were about right but if not feel free to correct me

 

There's a spring inside that is only good to a certain pressure before it starts to leak boost past it. Crushing the top helps the spring have more tension and hold more pressure without leaking.


Here's a picture of the top pushed in:

I had a 1gen bov uncrushed on my crx and it held 19 psi constantly.
