Compressor Surge with BOV
 

I have a turbo del sol d16z6, I have a 14b, when its cold for like the first few minutes of driving I am getting compressor surge with no blow off then after a lil while the blow off valve get louder and louder but no matter what I still get some compressor surge, I have an HKS super sequential Blow off valve, I have it the spring tension on it set back almost all the way, the wastegate and the blow off valve share one vacume source at the manifold, and ideas or is this normal

Re:Compressor Surge with BOV
 

sourced behind the t-body, right?

Re:Compressor Surge with BOV
 

no there is a vacume part to the right on the manifold with a conector going in it, I have them t'd there

Re:Compressor Surge with BOV
 

Sounds like your on the right track by lowering the spring tension down.

Next step might be to try and run a dedicated vacuum line to the BOV. (The largest size permiting)

Re:Compressor Surge with BOV
 

yea i just meant that its between the t-body and the motor somewhere

Re:Compressor Surge with BOV
 

there are only 2 vacuum sources though the other vacuum source I have the Adjustable fuel pressure reg, Vortec FMU and the Boost gauge so I don't want to throw anything else into that one cause thats messing with fuel pressure. I mean i can tap like 5 1//8 nipples onto the top of the manifold, but I want to know if this is normal, I mean I don't think the blow off valve is broken right cause its still letting off.

try adjusting the screw the opisite way, and try getting a different source off the intake manifold.
