quick q re: greddy type s bov install
#3
is the UIM nipple i have leading to the BOV identical to the nipple the boost gauge is connected to? or might that be the so called "turbo line" hm im clueless, since its my understanding the two are the same.. that they both see vacuum and positive pressure? or am i way off.

my interest is that i have read that the slanted nipple helps BOV reaction time when whatever should be hooked up there is hooked up
but it is functional as is
also is there a diagram of air flow through the system? ive been reading a interesting thread on BOV placement on the intake path

being the stock setup, the way you have it is fine, that's essentially how the stock bov is connected. The only other method os install is using a flange that is welded to one of the hard pipes goin into or comming out of the IC.

"The GReddy valve has two fittings for small vacuum lines on it. The top fitting is for the same hose that went to the original stock bypass valve, the hose that goes to the intake manifold. The lower fitting is normally left open. It is a vent for the lower chamber of the valve.
On some cars with large turbos, compressor surge at light throttle lifts can be further reduced by connecting the lower fitting to a pressure source. Typically a fitting is added to an I/C pipe between the turbo outlet and the valve. "

hey vegas since u're still up.. how did you adjust your spring? from what i've read its best to adjust the bov as hard as possible w/o having surge. any idea what the correct procedure is? im thinking of starting soft and adjusting hard by doing 3rd gear WOT runs (in order to produce max boost the system usually sees(?). once i get surge i'll know it has to be turned down a bit softer.
+ what should the bov sound like when spring tension is set correctly? from a few minutes of playing around with it today i notice the softer its adjusted, it sounds more like a HKS ssqv high pitched.. the harder settings result in a soft "whoosh".
also i don't understand why the slanted connector shouldn't be used for stock turbo setups as well stock turbos should suffer from surge the same way large turbos do, only at a smaller scale. i wonder if it is possible to tee off a pressurized line somewhere? i have very limited knowlege of how the turbo system is put together.
