Here's a picture of the rigged up BPV so it doesn't leak air. @JP@edgeautosport.com

Oh my god, did someone throw up on that and let it harden over night to seal it?

Why did you guys block it off anyway? Did you try to see if it held boost with it just VTAed so you could just run VTA until you figured out the recirc location? If the intake didn't have the recirc location to begin with, this would have just been a VTA setup.

I didn't read this whole thread so maybe I'm totally off on what you guys are doing.

Maybe he can explain but when it was VTA the car didnt run well

Ugh gale you fucking idiot.that's not something you fucking show people. Anyway

Jp the cobb bpv design is fairly odd. The vta cap actually fits on the "vent" side and leaves the recirc side open. Issue here is it leaks air at idle, quite a bit too through the recirc side. And yes I adjusted the sprring to no change. Not sure if cobb intentionally designed the bpv to leak I know some actually are. In contrast my turbosmart had the cap off on the recirc side which was the opposite for the cobb. Another thing I recommended gale to buy a new bpv/bov and this was only temp. His car was running like dog shit, he had to work that night and he lives a good 40 min away. It was also getting pretty darn late. I guess its my fault for vnot properly educating gale but it works, and being pressed for time imaking something "clean" wasn't my top prioity.

Its ok Derek I know it isn't going to be permanent. Daddy Chinkus FTW

Update..

Injector seals in and Bosch 3Bar Map installed as well.

Still having big issues with boost creep and trying to figure it out with Lex

Do you mind posting a log of this creep.

[86AmishMs3]

From what I've seen big inlets and catless exhausts have the most issues with creep...hence why I ended up buying a catted downpipe after the fact

Sure heres 2 logs. First is a 3rd gear log of me easing into the thorttle to watch the boost. Same with the 4th gear log.

That looks very similar to what @Broxers and stangs gtx3071's were doing. Once we brought the boost up in the lower rpm's and made the turbo work, boost became stable and controlled all the way through through the rpm's.

[Lex]

Big intakes, opened exhaust, and inefficient WG designed = creep and spikes

First thing to try is to reduce preload on the WG arm/flapper.

What happens when Broxer floors it at 4500-5000 RPM instead of starting at 3000 so the boost stabilizes? You can't get away from a shitty WG design - you can only work around it with throttle control and increasing backpressure.

Cale, post datalog 84 where you're flooring it at 4200 RPM.

It's stable. I'll get a log to post later.

[Lex]

If it's stable then there's something different about your setup in terms of preload or intake/exhaust flow. You can't use a boost controller to turn boost down below what the WG on spring pressure alone can do.

[Broxer]

Here's a timeline of what i've experienced:

Turbo in running on spring pressure: Hit boost cut (22.5psi) near redline. Otherwise built boost really slowly.

Trying to use stock BCS... which i had hooked up incorrectly. Cause boost to go from like 3psi to 22.5 in like 1-2 seconds.

Grimmspeed: boost built slowly and still hit boost cut near redline. Once @atvfreek got the boost to come on faster, around 20psi at 4k rpm then it stopped creeping.

In fact we were able to dial it down to ~19psi @ redline because I was hitting my MAF cap and gettin cut.

If I got any of that wrong atvfreek, feel free to correct me.

So you were just experiencing slow boost response and then creep. Cale is experiencing spiking and creep as well. On just spring pressure if he floors it at 4k RPM then boost goes to 24psi. First thing to do for him is to decrease the preload.

I have my preload set to 0. I had it set to 4 turns tighter but changed it when i was getting spiking on the stock BCS.

Heres datalog84 for you smart guys. I'll see if I can get that preload fixed on wednesday morning.

Also got my Go Fast Bits BOV to replace the Cobb one that wouldn't run in VTA mode very well.

[atvfreek]

Datalog 84 certainly looks different than the other logs posted. Boost is doing whatever it wants. Hopefully decreasing the preload as lex suggested will take care of that 24psi spike.

[SleeperHatch]

Update: Reduced the preload yesterday and spikes are gone but there is still a little creep but we can finally start tuneing.

Also noticed in order to reduce the preload the once the head is off the swiveling piece and the nut is loosened you cannot turn the head like most videos show you have to actually spin the entire actuator arm and in order to do that you must remove the 2 nuts that hold the wastegate to the turbo, pull it down spin the arm a few times then bolt it back up. It was a little annoying but not hard at all.

haha it was a pain the arse to get my wga out because that coolant hard line is right behind it.

Getting that arm back on the flapper was a PITA too. Definately needed 2 ppl.

Is your boost oscillation under control now?

Haha yeah I had my pops up top just slip the arm on the flapper took him like 2 seconds while I tightened the nut and got everything buttoned up. Having two people is nice don't have to keep getting up from under the car and going back under multiple times. The hardline actually wasn't even an issue for me. I'll attach a few of my newest logs so you can see. Although I am just on spring pressure right now so remember that when looking. Oscillation seems down and spikes arn't there but creeps for sure are still there but should be managable because I wanted to run 24psi anyways.

Mine was creeping similar to that on spring pressure. The oscillation prolly wont be evident until you get the BCS hooked up.

Compressed air is your friend in that situation. Muscleing on the arm back on is no easy task...unless you have a air compressor.

problem is youre at 24psi @5800 rpms.....Add another 1000rpms and you might be 26-27psi. You're uncatted right.

Yeah but were also still at the beginning of the tune. I have a catted CNT downpipe, so its just a high flow cat.

Wow you're still creeping with a cat..well once you dial in some more timing you should see less creep.

[QwkEVO]

Sleeper, sorry for the thread hijack, I just want to possibly avoid the same potential problem.

Crap, I hope I dont have this problem when I do my install this weekend. I also have the Cobb BPV, although it works fine currently in hybrid mode on the stock K04. I have the 14 psi spring in my 3071GTX. You guys think I should take the preload off before installing? I didnt port the WG housing either, wonder if I should do some minor porting of that half moon shaped area?

I'm running a Vibrant DPBE which does have a high flow cat. I have a corksport downpipe...

Any suggestions to help me avoid this potential issue?

Yes port the WG and you won't have nearly as many creep or spiking problems. Also if your running a recirc tube still on the inlet then the Cobb BPV is perfectly fine. My inlet is essentially just a bent 3'' aluminum pipe. Preload is easily adjustable as well kind of annoying but not hard to do at all.

[TRSpeed]

Gale any updates?

[driver311]

I found that the wg hole definately needs to be opened as far as possible. Pretty much as far as you can go without seeing the opening with flapper shut. Also adding a high flow cat helps a ton and doesnt affect flow harder at all. ON a 400whp car expect to lose about 3-5whp. Magnaflow cats sell for about $85 dollars and make the car sound so much beter in my eyes with 3in exhaust. I guess its all preference but I hate my car sounding loud like a civic or srt. lol

[SleeperHatch]

Well I might have to open it more then. Tuning was going great amd spikes were gone and creep was controlled and now all of a sudden I'm spiking to 30psi again, Lex thinks something might have popped off which sounds most likely ill be checking soon but since I'm sick and feel like I have the bubonic plague it won't be today.

So I've decided I'm really tired of trying to deal with this damn IWG so I'm going to be getting Daddy Chinkus's manifold and wastegate and just run EWG and be done with it!
