just finishing up my build tn and wanted to check want any1 had to say about how i ran the vac line ..also in what order should i tee in the boost gauge ..thankz in advance ..if its nt clean in the image what i did was run a line from the intake manifold to the evap solinoid and teed off bov and wastegate in that order ..i am pre tune i kicked it over and it sounds good (rich but great idle )..but the bov does not activate at all and evap solinoid sounds like its ticking ..tuning related?

the evap always ticks because it pulses air into the manifold. BOV needs a load in order to blow off. i think that's the correct way to route it

BankerBalt

or wait. doesn't the vac line from the turbo go onto the wastegate?

NICOMAN

there is no vac line on the turbo ..i have seen that set up b4 tho but theres not one on mine..and yeash i figured with the evap..intead we ran from the brake booster for strongr vac and no pull from th evap..i was barley getting vacuum ..so now i have it ran st8 like from brake booster to the wastegate and teed from bov and boost gauge in that order

Get rid of the evap solenoid and just connect your boost gauge on the end of that. I'm very careful about boost control. If you can tap the hot side charge pipe with a fitting so you can run that to the wategate, that would be preferred so it has pure signal with no other connections in the line. Just my opinion

My BOV doesn't open all the time when I'm just sitting still in neutral while the car is running. Sometimes it does, sometimes it doesn't lol.

Can't see the wastegate.. Looks like you're running off the spring? Looks like a tial?

I T'd into the vacuum line before it reaches EVAP for my boost gauge. Either works I guess.

yes that makes alot more sense man thankz alot im going to try that now and see what happins ..just have to find a way to tap that pipe nice and clean soo i dont end up with a leak

NICOMAN

ur the sh** this helps alot..i have a tial wastegate with only one vac line tho ..the top vents to atmosphere ..and no boost controller but this still helps

NICOMAN

oh and where is the vent house going to ? rn i have mine with just a breather

NICOMAN

all this helped and im going to switch som things around and see what happins..as of now my main concern is wtf is up with my boost guage..im pretty sure something is wrong because first off during tune on saturday we switched up the vac lines ran from the brake booster to the wastegate and then ted off bov and boost gauge in that order..now my boost gauge is only realding -10 ..to my understanding my vac sould be at aroud 20? soo we thought vac leak right? soo my assumption was 2 places i could be getting vac leak..the maf sensor housing (universal) or the bov..sempt to be almost open at idle..just kind of wispering out (zzp's tial mock up bov)..soo i deleted the maf housing and ran a str8 pipe where it would have been and i had an extra bov laying around (lil ebay one) and i poped that in just to see if any vac changed and it didnt..steady at 10 ..soo either where i currently have my boost gauge teed in is all messed up or mayb im getting a bad ground? but i dont think so because its zeroed out when i put the key in b4 ignition ..any ideas? going to change the vac lines around and mayb that will make a change..untill then any help trouble shooting this would be great

Lite up a cigarette and use the smoke to see if you have a leak or not. Vacuum should read 20-22 at idle. Ditch the breather on your valve cover and actually route it to an oil catch can and back to your intake.
