For anyone interested, I will be spending about $1,300 on the following for my EWG hybrid build:
Grimmspeed MBC (I already have the GS EBCS)
Grimmspeed 38mm uppipe
38mm Tial EWG
Grimmspeed wastegate bracket
Deastchwerks DW65c fuel pump kit
ID 1000cc injectors

I am being forced to go with an EWG due to the boost creep of my current setup (I'm not complaning though ). What I plan on doing is tuning the MBC to control boost at WOT and the EBCS to control boost at all the other rpm ranges. I personally hate flutter and love the scream of the EWG + MBC, which is why I decided to go with the hybrid setup. When I purchase and install this in a month or so, I will post back in this thread with my results.

You shouldnt be having boost spikes on a stock turbo.

I meant creep... just woke up from a nap so I used the wrong term. My OP states I'm doing this because of creep and I cannot wait to get rid of it

Still should have creep lol Plus, I would just run the EBCS, no MBC in your case. But its not my build You'll probably be happy with the result

VF52's creep pretty easily with a free flowing exhaust and intake. No tune can fix it. EWG is a good solution. If you don't want the flutter, then the hybrid set up is a good choice.

ie. Everything you have planned sounds good. Don't listen to people who don't know what they're talking about. There's a lot of bad advice out there.

Most of the time creep is in the tune. If you're the very small percentage that it isn't in the tune, other things, like a EWG, can be done to control it.

I am just personaly not a fan of a EWG on a Vf.

Tuning has nothing to do with, nor can it fix creep.

People commonly mix up boost creep and boost spike. They are two fastly different things.

My car used to SPIKE to 20psi before I massaged the tune myself.
I had a tune problem.

I helped tune someone car that, no matter what we did, would CREEP up to 22psi at redline, even with his WDGC's set to zero. He had a mechanical problem.

awesome thread..i am currently on the hunt for EWG setups for my car too. im running the accesport ots map with the vf39 and supporting mods. im thinking of going tial 38mm ewg with a 1 bar spring. and selling the Cobb AP to pay for a tune at 22 psi.

Lowering boost through tuning can help/fix creep.

That's a good way to put it, thank you for simplifying it for everyone!

It can just help to make it's presence less obvious... a better way is to mechanically eliminate it

I'm well aware what creep is. Creep is much more common on things like DSM's. Lots of those will E3 16Gs will creep into the mid 20's no matter what. That is true creep and nothing can be done without mechanical modification.

Many people think they have creep even though they do not. Usually when their tune calls for, lets say 18 psi, and sometomes it goes to 20psi consistently, especially in higher gears. They say it "creeps", but it isnt real creep. Without seeing said car in person or seeing datalogs I couldnt tell you which is the case.

Here's an update for those of you who are interested. I couldn't wait the full month like I had planned; my parts are coming next friday! I am going to wait to get the injectors so I don't rape my bank account too hard at once and I'm going to use a safe tune from Eric at Torqued Performance for a hybrid EWG setup *dons ye old flame suit* In another month, I will get the injectors and head to EFI logics for a protune. Since I plan on lifting the engine to get the uppipe installed, I will also be doing Group-N motor mounts and a Kartboy Pitch Stop.

I'm going to take a video of my car before and after I install the EWG, trying to capture the sound difference and boost creep elimination as best as I can. Let me know if you guys are interested in seeing the results.

Saved and interested in your results. I have a while before I will be going stage 2, (most likely late next summer or longer) and have been researching the crap out of EWGs.

Edit: Did you run your list of mods by Eric, or just pick them out yourself? What did he have to say about what you chose?

Picked them out myself through extensive research then talked to Eric about them. He's going to tune my Hybrid EWG setup so that the EBCS controls partial throttle boost and the MBC controls WOT boost. If you want him to tune a new set of injectors for you as well, you'll need a wideband.

Just another update.

I finally received my parts 2 days late due to the recent hurricane, but I'm glad that they're here at last! I will be installing them at about 2pm EST today and posting a video of how the hybrid EWG sounds with my current setup. Here's a video of how it sounds with my current mods:

I'm still not 100% sure about how I am going to hook-up the two boost controllers, but once I figure it out I'll post a diagram for those who are interested


EDIT:
My stupid mechanic didn't allot enough time to install my parts today, so I will have to wait until saturday. Stay posted for results.

The flutter doesnt bother be but its not for everyone.

Make sure you get with your tuner on what spring to run. Im running about .1bar to light but I experience almost NO taper.

Make full boost (19.5psi) @2700rpm also =D (VF52)

2011 WRX EWG - YouTube
FYI, my EWG never fluttered like that. It was rock solid holding 19 or 20psi to redline on an evo316g and I only very briefly used the hybrid setup. 3 port BCS and there should be no fluttering if it's tuned properly. This was with a 38mm. I dont remember which spring I had, but it started to crack open around 10psi and was fully open by 14 or 15.

You can really hear it in the video on the top end when it's just roaring. That flutter would drive me crazy though.

Do you happen to have a sound clip of your EWG + EBCS? It would be interesting to see, especially because you have no flutter with only an EBCS.

P.S. You were probably running a 1 Bar spring on that EWG if it opened near ~14psi

When I get home I'll dig around for an old clip. I'm on to twin scroll now so I no longer run the ewg unfortunately

I would guess that WGDC and the spring run in an EWG setup affect how audible the EBCS/EWG fluttering is.

Properly set up there shouldn't be any flutter. Your turbo dynamics in your map need reduced significantly after going to an ewg setup or you will see fluttering. It takes so much less wgdc that you end up needing much smaller changes to maintain boost levels

So pretty much you're letting the spring control boost levels with minimal assistance from the EBCS? Or did I interpret that wrong like a newb
