help with my friend's BOV
I dont think my friends BOV is working. He is running about 18lbs of boost. The BOV is a Tial with what he thinks is an 11lb spring in there.
Whether fully boosted or partially I havent heard the BOV while i was driving it. I simply here compressor surge.
Oh, and it is hooked up to a vacuum line on the top. I know alor of people dont run that.
Any tips would help he and I are noobs.
Thanks folks.

I run an 11psi spring and it blows off great at full boost. But in partial boost conditions it doesn't like to open fast enough and i hear some comp surge. I drilled and tapped my upper plenum for 1/8" NPT and the BOV has it's own dedicated vacuum line which is much bigger than what fits on that little baby nipple near the throttle body. That should be your first course of action.
I would take the BOV apart to make sure it's all in there straight and to verify the spring. If it's silver, it's the 11psi one.

I have seen the oring on the valve stick before. A light coating of lube helps. Makes sure the signal line is hooked to a port on the intake manifold at least as big as the fitting on the wastegate.

BOV's....? who needs em
nothing beats the sound of boost banging around in the pipes, sounds cool when you shift too.
But seriously, a friend of mine has been running almost 20lbs of bost on his 18g setup for a few years,and over 60K miles. His turbo is holding up fine, and the increase throttle response is astounding. The lubrication on modern turbos allow for longer lifespan and more durability under abusive driving,
just a little food for thought

I don't suggest cutting the spring. It's a specific length for a reason. Cutting it might be a ------ rigged way of lessening the pressure on the valve but you're not really reducing the springs rate. Cutting the spring might make it leak at idle, thats the last thing you want. Your spring is currently worth money. Buy the 9psi spring, sell the 11 on ebay.
Where are you getting vacuum from? If your vac source is too small, it won't blowoff right. The Tial is one huge *** piston. Give it the air it needs. Mine works fine with the 11psi spring and i'm only running 8psi of boost. Only times i have surge is when i get into less than 4psi.

I am getting vacuum from the vacuum line right above/past the throttle body.
It is a smaller line. Should I maybe tap into the big *** vacuum line that goes to the break booster? That's the biggest on on my mani.
What one do you have it on? Do yuo have the stock size banjo/vacuum bolt on the Tial?
Thanks bro. I appreciate it.
OK I just uploaded this, so I can stop fukken around
is this vacuum too small and ****?
