jackal8788 Posted April 27, 2015 Author Share Posted April 27, 2015 It begins - just ordered the EBCS from jojorios. I'm checking with a couple shops around here on the possibility of fabbing up something custom or modifying the stock headers. Also may move on SomeZero's header depending on what I come up with here. I keep thinking about the stock setup and the ETS option - wouldn't it be possible to have two tubes welded to the stocker just like ETS? I haven't looked at it in any detail so I might be missing something but the concept seems possible....

BigBopper Posted April 27, 2015 Share Posted April 27, 2015 The OEM header is double wall piping, which may make modifications unreasonable. Link to comment Share on other sites More sharing options...
acumenhokie Posted April 27, 2015 Share Posted April 27, 2015 The OEM header is double wall piping, which may make modifications unreasonable. ^^^^^This Be sure you mention that to any shops you talk to about custom fabrication. It's not really possible to modify the stocker. Link to comment Share on other sites More sharing options...
jackal8788 Posted April 29, 2015 Author Share Posted April 29, 2015 Continuing down the path of part procurement, I've noticed that a lot of EWG setups with EBCS have a fluttery sound due to the cycling of the boost solenoid. One way to eliminate this is by using a manual boost controller. Is anyone else running EWG with an EBCS that does not experience the fluttering or is this inherent in that configuration?

Rutchard Posted April 29, 2015 Share Posted April 29, 2015 Unfortunately that's just how it's going to be with the way the EBCS cycles. MBC all the way. Link to comment Share on other sites More sharing options...
jackal8788 Posted April 29, 2015 Author Share Posted April 29, 2015 That's what I was expecting to hear. So I will likely be selling the EBCS I just bought from jojorios and picking up an MBS instead. There are a crapload out there - any recommendation on something you've had good luck with or something to avoid?

jojorios Posted April 29, 2015 Share Posted April 29, 2015 I was also looking at the MBC, but the tuner was really not a big fan of them and suggested EBCS. Something about it being a pain with temperature changes. That's how I ended up getting the EBCS. When I was looking into this I also came across a hybrid setup that uses both and MBC and EBCS, which didn't look like it creates the flutter.

jackal8788 Posted April 29, 2015 Author Share Posted April 29, 2015 I'll have to do more research on this as I really don't like the flutter sound at all. VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...

jackal8788 Posted May 1, 2015 Author Share Posted May 1, 2015 Talked to my tuner a little more and he recommended a hybrid setup with both MBC and EBCS. MBC will control peak boost while the EBCS allows for boost taper at upper RPM and boost cut in case of knock as shown: VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...

MBC will control peak boost while the EBCS allows for boost taper at upper RPM and boost cut in case of knock as shown: Did your tuner mention anything about temperature change affecting the MBC in this setup? I really wish I had a local subie shop/tuner I could fully confide in. The subie shop I used is the only one I know of locally that has a good rep, but when I asked about the MBC and the hybrid setup, they pretty much told me they won't do it because the MBC can be a pain with the seasons.

No, he didn't. In fact, he said this is the setup he recommends most highly for those who want/need precise boost control and that it is what he runs on his own Legacy. I guess I don't understand how temperature could have any effect on a manual boost controller. The controller is just staying closed until the spring cracking pressure is reached, then it opens up. Since the spring cracking pressure won't be influenced by temperature (within the range of temperatures it's going to see in real-world use) or atmospheric pressure, the boost setting shouldn't change either.

Rutchard Posted May 3, 2015 Share Posted May 3, 2015 I think it's less of the cold actually affecting the MBC itself, but more how turbos just seem to generate a lil more boost when they're fed extra cold & dense air. Link to comment Share on other sites More sharing options...
BBPeik Posted May 3, 2015 Share Posted May 3, 2015 I wouldn't think temp would have much affect either. Even though in cold weather the dense air creates more boost the mbc is pretty simple. Pressure makes it open and that is that. I would be interested to hear more about the shops theory on weather making that setup a pain. Hmmm My someday I will be done with it thread.

jackal8788 Posted May 3, 2015 Author Share Posted May 3, 2015 Agree. More dense air = potentially greater pressure but the controller doesn't care whether the boost is due to air density or air volume being compressed. It just has a setpoint at which it will open.
