GFB Blow-Off Valve // Mitsubishi Galant VR-4
What a fun mod - a little something extra to remind me I've got a set of turbos under the hood hehe.
I was initially adamant I needed an adjustable valve as I didn't want to be 100% VTA. I thought that a car like this would be constantly boosting therefore unable to mask a fully venting valve. I did however find that I had to be building some decent boost before it vented too loudly and this is because of how the spring preload has been set.
TLDR: Can easily mask the noise with some gentle throttle control
