jacob80 Posted March 26, 2010 Share Posted March 26, 2010 Hey fellas, Well I was just watching some L28ET videos and came across this: Now, if you listen, you can hear a distinct surge sound between shifts, it almost sounds futuristic. I realize its the turbo system, but what exactly is that sound? It doesn't sound like a bypass valve, so what is it? Is it good, bad, what? Thanks!

Snailed Posted May 10, 2010 Share Posted May 10, 2010 The first video is compressor surging because the blow off/bypass valve is too tight or there just isn't one installed. The 2nd video is a ssqv that is too tight and causing some surge. The fluttering sound is bad it beats the hell out of your thrust bearing in the turbo and can cause more damage in extreme cases. A proper setup (imo) is one where you only hear the air rushing out, not beating up your turbo. Quote Link to comment Share on other sites More sharing options...
