guys i got my tial wastegate plumbed in like below however the nipple that is venting to atmosphere is leaking vacuum, guessing thats not right lol can someone confirm the correct way to connect it up?

theres 5 nipples, the lower 3 are blanked off, so theres just one on the side (which i routed to the inlet manifold vac source) and the one on the top which is venting to atmo.

thanks - dan

 

backwards

leave top 2 open
put the pressure source to one of the bottom ports, plug the other two

 

ahh got ya. i was plumbing it like the old style tial's.

thanks matey

 

this one is no diff from the previous gen aside from the two extra bottom ports and one extra top port

 

thanks mate, whilst your here, is the 50mm bov supposed to be almost fully open on idle?

 

what spring are you using and what is your vacuum at idle?

 

.7 psi spring.. erm not sure on vac @ idle will have to check. (its an AFI turbo kit, so this spring is what they sent with the kit)

 

 

this look right ?

 

where is your MAF/MAP sensor located?

 

on the throttle bodie why?

 

if it's post bov it doesn't matter if it's open
if it's pre bov it needs to be shut


so you are good to go with it beign after the BOV

 

thats cool, thanks again buddy.

 

guys, was just thinking, is it not abit dodgy to have the bov open on idle, as its drawing in un-filtered air.. ??

 

it's venting air out, not sucking it in

 

at idle...your wrong. it sucks unfiltered air in. thats how bov's work

 

i think we have a pretty good understanding about how a BOV works, thanks

 

That is funny right there!

 

Sig worthy

 

I know it's been quoted a few times already, but damn that was funny. Caught me totally off guard

im sorry but a bov sucks air in at idle when its open.

 

Exactly, for being a company that is some poor *** attitude TiAl. You need to learn how to read; turbodailydan said its drawing in unfiltered air at idle, Tial's response is it is venting air out at idle, so good one. I don't think you know what you are talking about, it can happen both ways, loose customers much?

We all know a "Blow Off Valve" releases excess pressure. When there is a vacuum present I guess you could have the crack-head theory that it is still "venting off" negative pressure. Wow, what a different spectrum, BOVs are BOVs all the time they "vent off Positive as well as Negative pressure".

I am now a crack-head.

 

Mine blows air out at idle. Some setups do suck in though, depends on how large of an opening the valve has and if the turbo spins at idle.

 

LOL

ok so, is there any potential issues with the piston being open on idle..?

with having a bov spring this soft, is the bov going to be venting off on the slightest bit of boost? i dont want it ''woooshin'' like ALL the time

 

AMEN Brother. Typically though, the BOV is sucking in air at idle rather than blowing it out on a lot of your average turbo setups.
