Own and home made double piston Blowoff valve for my punto GT

I found the commercial price a bit too high for an assembly like this, so I decided to design and manufacture one for myself.
It sounds pretty good and costed only 1/10 price comparing to a commercial one. And this one is precisely adjusted for my car only:)
Design and initial testings were performed in Solidworks with student license. Manufacturing was made by hand controlled common lathe.

@2FuriousFreak If you want, I can provide some drafts(blueprints) for it. However, the springs must be selected by you specially for your car! Cheers!
