compressor surge

[tlo86]

now i am wondering why i am getting surge so bad, i just got the synapse BoV to see if it would cut it but it is acting just like my HKS did... getting kind of frustrated and i know maybe i am just having one small detail im missing.....

i first had trouble with the vac lines being blown off, with a few zipties the hks worked pretty ok it only surged a little bit )hardly at all actually).... but the next day it didnt function the same.

so either way im thinking it just is not flowing enough air out so i buy a second blow off valve, i chose the synapse one.

it acts like the HKS when it wasnt working only the time it surges is shorter but seems to work better overall i guess...

is there something i am just looking over causing this that anyone knows of? i get surge like my bov isnt even hooked up.....

the bov is mounted right after my 90 deg off the throttle body. it surges pretty much whenever i hit boost... 1 psi 14 psi its not picky

its just weird that it worked fine then it started hardly working at all on the hks...

surge at everything over 4psi i guess i'll just install my other bov with this one

did you remove the stock bov?

did you remove the stock bov?

yeah i have a 62-1 turbonetics ballbearing, never even ran the twins (cant believe i forgot to mention that )

are you running the BOV on its own vacuum source, or is it t'd off another line


i had bad surge on my racing type II till i gave it its own source

 

[tlo86]

its own source off the intake manifold. the synapse also has a secondary line you T off on the primary line or whatever (kind of hard to explain that s why instructions had pictures lol) but i have tried that way and T-ing that one off (the second vac port on the bov to the p/s vac ).

i ran the HKS off the line and thats kind of where i felt it was doing a decent job but then went back to crap surging every time

Maybe I missed it, are you getting surge at shifts or as the boost builds?

 

[tlo86]

shifts never as it builds. im just thinking its not releasing enough air out

 

[tlo86]

ok i talked to the synapse guy and there is an extra port for if you are boosting more than 7 psi, appearently i had an outdated manual that said it was unused and he linked me the updated manual. i needed to feed that to a pre throttle plate boost source and wow the difference was night and day, i still have a split second surge between shifts at above 10 lbs but the bov seemed to help a ton

 

[tlo86]

need to fix those vac lines
