Don't know where u read there but that vac take controls just the bpv, it in no way can effect spool time cause it has nothing to do with spooling the turbo, and it had nothing to do with nls, nls is controlled by the ecu using timing adjustments or something like that, vac take has no possible way of controlling nls, all it does is control the opening of the bpv when u let off the gas, bpv is opened when vacuum is applied to it, more vacuum, the faster it opens. That's all the canisters function is. All that other stuff is miss information. And the fact that its louder is by experience, I took it off , and my blowoff became louder, also with it off the bpv stays open longer so when u let off and the bpv is open, it doesn't just let out air, it also lets out turbine sounds so they become a lot more Audable, this is what I observed, best way I can explain it. If u dot believe me, if u got a K&n , bypass the canister and see for urself lol

 

Terminator did it, and I did it also. Haven't had any issues. I think mine was bad causing a leak but its been deleted for over a month now.

 

I don't doubt any of what your saying. Becasue frankly im not too sure what the tank does. I would love to bypass mine and see how it sounds. I currently took my kn sri off to clean the filter. I wont be putting it back on for a bit. So im wondering if I will notice any difference in it with the stock air box. But frankly , I'm still kinda confused as to which hoses to remove and or connect or dissconect where and what !

 

if you want, when i get off I can take a picture of how it is routed on my car.

 

If you could a picture and a litttle how to would be wicked ! And much appreciated !! Thank you !!

 

Stock looks like this. You can see the two lines going down to the tank.


Remove those and replace with one line, like this.


It's something like a 7/16" line.

 

Thats it ?? Just disconect that one hose really from the intake manifold and put the one that comes from that black box thingy onto the intake maifold spot ? What then do you do with the line that was on the intake maifold ? It almost seems to simple !

 

Yep. umrdyldo picture is how mine looks

 

Yes it's that simple. If you don't ever intend to put the vacuum tank back in, just cut off a long enough piece for the new line off the existing lines to the tank. CAUTION, don't cut the line that goes to the lower charge pipe.

 

What did you guys do with the original line that WAS on the intake mani before ?? Just leave it hanging around ? Or did you guys cap it off with something ? Like a vac cap or something ? Or did you just leave it hanging around ?

 

The best explanation I've heard on here for the vac tank is that since the 'Balt was engineered for road racing where you're constantly on/off the throttle (and in/out of boost) there may be times where engine vaccum isn't sufficient for quick bpv operation. The tank stores vaccum to assist this scenario. Some people (including me) feel bypassing the tank to a direct vac source can help the bpv react slightly quicker and (MARGINALLY) reduce lag. I don't leave mine bypassed as some of the tuners have indicated it will eventually skew fuel trims (w/o a custom tune). Feel free to correct me if I'm wrong.

 

I don't see why it would seeing as all it does is assist in opening the bpv, if it were to skew trims it would do it right away not after awhile, not like the ecu suddenly decides after its been bypassed for awhile, hmmm I think I'll skew the trims cause he bypassed the canister, no if it makes an issue with trims, ecu would see it right away and those trims would be skewed. Lol or so logic would dictate

 

On a stock tune the car is designed to use it so the fuel trims would be off, but by how much is the question. The answer is not much so nbd.

 

Next time I go back to stock ill check

 

don't mean to thread Jack, just felt this may be interesting to you guys..

alright, so with that said, I've been having flutter issues cuz the bpv wasn't opening, so I just by passed my tank and I just got done driving it around. went through a series of different boost levels in each gear and then I floored it in third gear at 3400-3500, only boosted up to 19psi. second gear only went up to 20.9 on the rpd.. I know I use to be hitting 22-23 before... mods= gms1, mpx catted dp. + cat back, KN SRI, injen CP

So what, that just means you are making more power at lower boost levels. NBD. That's a good thing.

 

so why am I making more power with less boost?, why would the vacuum tank by pass change that? (it was cold and damp yesterday when I was doing this, not sure if that makes a difference)



Posted from Cobaltss.net App for Android

 

Cold and damp temps will make a difference in amount of boost called for by the ecm.

 

GMS1 ranges from about 18 to 25psi depending on temp and humidity. So you are well within normal operation. It's not like a custom tune where you command a boost level.

With GMS1 they are trying to hit a torque/power level. So if it's colder for instance, the car needs less boost. Secondly if the tank got you into boost quicker then you would need less boost at lower RPM

 

Good point. thanks! ok so say I went with a custom tune, what's the easiest route to go?

The debate for that on this site is ongoing.

Price wise, Trifecta is a little cheaper and easier.

But most will agree with an HPTune. If it were me I would fork over the cash, get HPTuners Pro and then contact Terminator 2 for a tune.

Will cost the most but will probably give the best results.

 

only problem with that, I plan on running zzp cams valve springs and the zfr ( if this notorious flutter issue doesn't cause long term damage ) after the warranty in 2015 where they stated that will dyno tune it.. Just kind of figured why throw in 5-600 bucks on a tune that I will only run for two years. (unless they can just tweak and work with hp)

did this today, but it didn't fix my idling issue completely, so I must have more than a vacuum leak

 

My car has boost lag for sure since doing this and I have surge on deceleration.
Plus, I have the K&N intake, and it did not make my turbo louder by any means

 

It is impossible for for any turbo to surge on decel yo.
