Crushing a BOV... How?

[RT-AWD]

How do you crush a 1g bov? should i even do this if I'm soon to be upgrading my turbo to the evo III and putting on the punishment racing fmic.

To answer the question of how-to, you put the bov in a vice with a socket (or something) on top. Start by checking with a vacuum pump to see where it opens stock. Probably around 12 psi. You then SLOWLY crush it in the vice using the socket to put pressure on the center of the top and checking every little bit with a vacuum pump until you get it to the point that it holds the desired pressure.

Now, all that being said, I prefer to do the Dodge Garage upgrade to mine.

1.) Put it in a vice and crush it
2.) Be happy

Don't crush your BOV, its pointless if you want to improve the 1g bov do the dodge garage mod.

i'm running that with 20 psi+ no issues.

crushing just ruins the valve. At least with the dodge mod you can remove it if you want.

I ran 12.0's on a 50 trim at 30psi with a 1g bov modded per the instructions in that link after. I started having issue with my crushed bov when I was trying to run high boost on a 20G. Do it right the first time and don't look back.

ok, thanks for the help!

To make things easier, all you have to do is drill the hole, tap and seal the bottom hole. Don't even bother with the brake line.

On accident I did it an even easier way. I was using a 1G on my turbo van and made my own flange and gasket. The gasket was a fat piece of cork and I put it on backwards one time. Putting it on backwards covered up the quick release hole and it wouldn't blow off unless I was over 12psi or so.

I really like DDG's method with the solenoid though. More work, but when you're not pushing the car it will keep it from surging. I dunno if it would be quick enough, but you might be able to hook up the solenoid to a boost switch so it will keep it shut at Xpsi but when it drops below it will be quick release again without anyone having to touch it.

Or you could do what me and my brother did and use a FPR solenoid (the one with three vacuum ports) and rig it up so you could run it stock, then with the flip of a switch, it'll run in Dodge Garage mode(vents bov pressure to the atmosphere). The switch also connects to another open solenoid going to the wastegate and when the solenoid is closed, boost will go through a manual boost controller set at 24 psi. The car has an SAFC2 for this though so there will be 2 different tunes for the different boost levels
