soo got the hks on and it sounds like a mixture of a hks and the stock one. it has alot of compressure surge too what can i do

 

get rid of the Spring.

 

dont get RID of the spring... cut the spring down

 

yah the spring is in there where the block off plate is am i supposed to have it there

 

i mean put the stock spring back in. the dejon spring is worthless and hurts the turbo. causes surges after use for a while.

 

Doesn't really matter, as long as the rubber diaphragm is there all is good.
That's not compressor surge you're hearing, the bov simple flutters like that at low boost.

 

yeah it does that because the dejon spring weakens over time...not allowing the solenoid to fully open quickly all the time.

thus making surging and fluttering

 

Well if he's got the block off plate it don't matter what spring is in there

 

use the stock spring...fluttering is normal under low boost with the HKS...should be good once you swap the springs out.

 

i meant spring in bov

 

oh ok. cool

 

im going to make a video now so you guys can hear it

this is the video, let me know if you hear anything weird.
listen between the first 18 and 21 seconds of the video.

 

If your have the block off plate the spring is not sopposed to be in there. Have someone rev the car up while your under the hood fluttering is not coming from bov. Had same problem.

 

cool ima take the spring out tomorrow when the cars cooled down gotta work at five

 

Let me know how it goes hopefully I helped

I got Hahns blow off that was my problem too their customer device is worth the extra money for their products

 

I had it hooked up without the stock spring in the BPV...CEL came on...put the stock spring back in the BPV...CEL went away. Just food for thought.

 

hmmm that sounds like some serious surge .. it's more of a knocking noise.. if it really is surge and not something else your turbo will give out soon

did you install w the dejon install directions?

 

With the blockoff plate setup?

 

Hey Pookie, I replied to you on youtube... didn't make the connection you were on here too.

There may be a spring tension adjustment or some other adjustment on the BOV. Since you've got the block off plate, the spring you had in the stock BPV shouldn't matter anymore. I'd adjust the BOV to have less tension so it completely vents the air and doesn't open late/close early, causing that flutterdump/surge.

If all else fails, you may have to look into a different kind of BOV that will get you the venting you need.

 

ok so took out the spring and made no difference. so..... how do i adjust the hks bov

 

you can't it's NON adjustable

Here's what mine sounded like
