Compressor surge....

[c20h25n3o]

Ok so i have compressor surge :o

It sounds pretty, but i know isnt fantastic for my turbo. The problem is the BOV i have, i get surge at anything below like 2 PSI.

Anybody have any ideas? I adjusted the BOV, no boostleaks, and ive tried everything

The surge isnt too bad, but how bad is it for my turbo?

[the jdmchop]

compressor surge is the coolest sound ever!

yea even stock evo's that i work on do it under light boost!

is it realy bad on yours?

[c20h25n3o]

No, its not really bad, and it sounds sooo wicked :D

I just want to take all possible precautions so my turbo lasts me a little while.

Above a few PSI i dont beilive its surging, but because i have a huge open wastegate, i cant hear. It really only surges under like 2 PSI...

When your turbo spins backwards its not a good thing. Compressor surge occurs when the throttle plate of a turbocharged engine closes and the pressurized air is forced back into the turbocharger’s compressor housing causing the turbo to slow down. Compressor surge not only decreases the spool of a turbo but can also damage its center cartridge.

you are correct sir!

What BOV are you running?

Had a small boost leak, and adjusted my bov, fine now. Sounds fantastic.

Im running a HKS racing bypass valve (original JDM)

yes the HKS sucks but the WRX/STi uses a Mitsu part # on the OEM bov
