What's up everybody! Today I installed a turbosmart mbc and when I boost I cannot here my bov blow-off, rather I here my tires chirping alot. I was wondering if I couldn't here it because of my tires chirping. Because before I put the mbc on I could here it. I wanted to know was this normal or has someone else experienced this. I have the greddy type s bov. Thanks!

C'mon guys help me out because I don't want to mess anything up. I don't know if it's compressor surge or not. The car doesn't jerk or buck or anything under boost, it's just when I go to shift gears or just let of the gas it sounds like the tires chirp. I don't think the bov setting is too tight bcuz it's at the same place before I put the mbc on. Please let me know of something.

Re: mbc install
Did you install it properly?
Also, are you sure that the "tire chirping" sound isn't your BOV? What is your boost set at?

Re: mbc install
you'll hear your bov when you release pressure in your intercooler pipes anytime your throddle plate closes.

I set it up the way I had read up on setting it up. I teed into the bov line that goes into the intake manifold, I have a line going from there to the mbc, and the other end of the mbc is going to the wastegate actuator. The nipple on the turbo has a cap on it, and the line that was coming from the bcs to the intake was capped to. At first I set it at 13psi and I heard that sound. Then I closed the mbc all the way so that it would be back at the factory setting, which was 10psi and I get the same sound. I was reading up about compressor surge and how it's not good for the turbo. Maybe that's it. I don't know. That's why I'm asking. Maybe that's what that sound is instead of the tires. I just want ot fix it.

Nevermind, I figured out the problem. I teed into the bov line to the intake manifold. That's what was causing my bov to make that sound. I ran a line from the nipple on the compressor to the mbc to the wastegate actuator, and now all is good.
