The ultimate blow off valve? 

Written 09-16-08

The other night I couldn't sleep because I just kept thinking about new stuff to make, then I started to wonder how hard it'd be to make a blow off valve... Still couldn't sleep so I got up and busted open my cad program and downloaded some pics of various BOV's. Three evenings at a couple hours each and it's finished! It's loosely based on that wicked looking Tial one, but this one is completely my own design. The piston is 2" OD and top part is 3" OD, so it should be pretty huge.  Scroll down a bit and you can see a second design that I made, this one will be a compressor bypass valve (CBV) and better for stock-ish cars.  It will have 1" inlet/outlets and a 2" body, so much smaller than the big one. 

At first I drew it up thinking that I would make one for myself, then that's it.  But after thinking about it more and more the idea is really growing on me to start producing these and selling them to all you guys!  I would love to be THE guy for volvo blow off valves, even though they would obviously fit on any car.  Once I get my new lathe and milling machine, then convert them both to CNC (stay tuned for that project...) then I should be able to bust them out pretty quickly.  I'll have to whip up an at-home anodizing setup so I can make them all pretty!  Then after anodizing I'll bring it back to the cnc mill and engrave my logo into the top.  Can't wait to get going on this!
