thanks red, going to do vacuum test tomorrow, i got the white #9 in it now and it seems like its half way there, and the tial Q i assum will work with the tial flange i have on it now correct

 

Yes it will and it looks like it is about 30 dollars more than the regular Tial. I hope you get it working. I have only ever used it once and when I did I didn't do any of this as at the time I had 3 different BOVs lying around and just switched it to the HKS. (That was on a 91 Eagle Talon TSI)

 

ok i just went on dejons website and looked at the picture of how there tial is connected heres the link DEJON | Powerhouse and it looks nothing like what i have and or seen on these cars ??

sorry thats just the link go under BOV and misc etc and look at the picture

 

blk06 i have a tial Q, mines a 40mm and i have a 10lbs spring and i no exactly what u r talking about.. i have a aftermarket turbo now, (gt2876rs) but mine did the same thing.. flutter flutter pshhh, another thing you could try is take the stock vac tank and hook it to the bov, i dont no if it will work but its worth a try unless u want to keep trying with the different springs..

 

interesting, im gonna vac test it tomorrow and then go from there, do you think the 7lb spring would work also? nice car also haha

 

the vac tank to the tial will not work. it wont even open. the lighter the spring the more response you will have but it also may stay slightly open and idle. mine stays 1/4 open at idle but i also got rid of my surge. i would suggest the 7 psi. even tho our car says its 16 to 20 vac when under a load our tb is electronic and i have seen some delays on closing on some logs and therefor which would cause your 2 second surge. when i would rev it, it would open just fine. under a load it would surge then blow off. best way to solve it is a lighter spring. do you have relocated maf? if not you need it if your bov will stay slightly open or you car will basically shut off lol. pm and i can send you a pic to your email of mine. basically tial wants you to run a 6mm hose(i suggest fuel hose) straight off the tb to there bov. let me no.

 

i havent looked at tials products lately but do i believe there tial q is like 50.5mm bov not 40.. could be wrong.

 

i do have maf relocate, theres a 9 lb spring in it now ur says to get the 7?

 

first is it open at idle? if not then try the 7. if 7 does not work still than you got another problem. but chances are the 7 will work. just do process of elimination. try 7 and run it straight off the manifold to the bov first just to see if it works better. dont tee into anything befor you try that.

 

its open now at idle running off the manifold, i have it tee'd now, the Tee is the original vac line going to the manifold tee'd to the manifold and bov

 

ok well i would have someone tap gas real fast and see how fast the bov reacts. and when driving does it open at all or exactly what is happening. my vac line goes to my tial and just my boost gauge not to the stock bpv block, or threw the vac tank.

 

ok hudson were almost there i put the 7lb spring in, its sounding alot better still a little surge, but the time between the surge and the bov lessened alot, now i think its a matter of how my vac lines are set up with that bpv block, im just not positive how to run them the right way now

 

Which spring to use also depends on which Tial you are using. I am using the -9psi spring in mine with no troubles. I have the Tial 50mm though. Not the Q.

 

can you post pictures of the vacuum routing please

IMO, the BOV should have a DIRECT vacuum feed. It shouldn't share a line with anything else... that's just more stuff that could interrupt and disturb the vacuum feed and operation of the BOV.

 

so what u suggest i do im kinda lost on this one guys

 

1. Just making sure you are using a block off plate and left the old diaphram and spring inside the turbo?

2. I'm not sure you need the BPV solenoid hooked up at all anymore.
I think you would be better off just capping it all off and running the BOV only to the manifold.

I think this is how the stock vacuum lines go.

The nipple on the manifold goes to the vacuum canistor that goes to the solenoid (bottom nipple, closets to the bumper). Then it goes out to the stock BPV ( Nipple on the left, passenger side.) Then it gets a boost only source from the lower charge pipe. (nipple on the top, Closets to the fire wall.)

Give it a try and see how it goes. Be sure not to leave a vacuum/boost leak though.

 

ok, and no the spring and dia were takin out, just the plate is over it

 

sry for the random comment guys but could dejons upgraded spring ever cause a surge? just installed it and like it but was just wondering if it is something i have to worry about

thanks

 

i dont think soo, im sure someone tho will give you a solid answer tho

 

Dude what plate are you using? You can't take out the spring and diaphragm???? I'm so confused as to how you did that!!!! Do you have a newer style metal BPV cover? Or the plastic one?

Maybe I'm wrong but I'm pretty sure by leaving the diaphragm out you have a huge boost leak.

 

?? a lot of ppl have done this. the plastic piece simply unscrews and you put the new spring in and done, im still pushing the stock 15-15.5 psi with no leaks at all, i was just wondering if i could expect any kind of surge with the new stiffer spring

so yall r running the vac line straight to the bov...what about the bpv?? i heard you have to have maf relocate and a block off plate to run the vac line straight to the bov... just asking

 

ok the BEST way to run a bov on our cars is to block off the stock bpv, then connect your bov straight to the manifold(unless you have a mechanical boost gauge, then thats alright to tee) using what ever vac line the bov calls for. and have you maf relocated and dialed in. bov need a GOOD vac source with the least amount of tee items in it. if you have a tial they call for 6mm hose and to run it straight to the manifold. i bet if you ran it straight to you manifold with the 7 psi spring it probably would cure it up. if you still have problems i would suggest finding someone with a tial bov and swapping out just to see if you have bov problems.
