Ok soo the funds for the intercooler and hard pipes have froze due to no overtime and the acquirement of a girlfriend :rolleyes: but I went ahead and did one of the things I did already have to get it out of the way.

Can you find what it is?

More pics and some videos coming soon...

Hey, got busy but just went outside and took some new (steady) pictures...

Looks like a BOV near throttle body.

You are correct! And now that I've replaced that plastic "Engine Air Duct" as Ford calls it, I noticed through data logging that I'm holding more boost.

I used a HKS SSQV Black Edition BOV for this install...

I will get a video of it as soon as I can. It's quite during normal daily driving and even during semi aggressive driving its only as loud as the factory recirc valves. When you go full throttle on the other hand you can definitely tell its there. I guess you'll have to hear it to appreciate it.

What did you do to block off the factory bov? If you didn't block it off then the HKS will be much more quiet...since your venting off to two sources now. At least thats how it works in my SRT-4 and I'm sure the same applies here.

This is true... Factory, the SHO has two recirc valves and the "Engine Air Duct" which acts as a low boost BOV. The HKS replaced the EAD and I have yet to cap of the recirc's. I was actually just joking around with a couple friends about how loud it would be if/when I take those two recirc's out of the equation. :laugh_ti:

Yeah it'd definitely make it much louder! I'm betting the two recirc valves are on the turbo themselves and you'd just take them off and bolt up a block off plate in their place. Again the way it works on my SRT-4. Just take off the stock surge valve and bolt up a block off plate. Not sure if anyone offers a block off plate but sure a shop could easily fab one up.

Terrible idea on the srt-4. You want the bov as close to the turbo as possible. I went into a lengthy discussion about this with the engine calibrator for the srt-4 in 2005. He said if you run an aftermarket bov keep the surge valve in place and let it do it's job.

How loud is the bov compared to a wrx or a neon srt-4 with a blow off valve? Does the black edition have the high pitch whistle sound? I had one on my srt-4 back in the day, but I think it was the purple insert, and I remember it being really high pitched.

Blackwire.... where did you purchase??? Did the "T" come with it??? Not sure what benefit I would get, seeing as I am running a 3-bar sensor and see boost levels of over 20. EXPLAIN....... Would this help keep my boost levels higher through out the WOT runs????

Well initially I went with a Mopar Bov that leaked...was badly machined. Probably 90% of the SRT's out there run a bov on their cold pipe and I've never seen a problem? I mean you can run both bov's, but it just makes the aftermarket one you bought much more quiet. Why would there be a problem running it here? I've never ran into boost problems or surge problems with this setup. I have a Greddy RS. I run 23 psi (for the time being hehe) and it's fine.

Bob the BoV won't let you hold higher boost levels, they just stop blow back through the intake when you lift the throttle.

Adding a boost controller will let you build more boost and maintain it but the GT11 may not be able to sustain or if it does it might be outside of it's compressor map and just throw massively hot air into the motor.
We really need to get a compressor map for the stock turbos to see where they are efficient to.

BTW, I've started talking to a local turbo shop here in Phoenix to see if they want to look at our platform for turbo upgrades. I've known one of the guys there for a long time and they seem interested.
We'll see

If they can't do a complete turbo swap, ask them if they can develop an internals package as an upgrade.

If your mopar bov was leaking, then it was installed incorrectly. I pushed 20-25 psi in the system without a single issue.

Being closer to the turbo will allow it to release all the air that didn't make it into the engine. When you put the bov that much farther up the piping it will allow some air to slam back into the turbo. I didn't care for it, because it was too loud and blew off in vacuum. When I did use a bov, I left the stock surge valve in place, and put the bov on the cold pipe. It does make it quieter, but it was still loud. Unless you were entering in the loudest blow off valve competition, I didn't see a reason to pull the surge valve.

Re read my post, the mopar bov was machined incorrectly. Kind of hard to mess up three bolts unless you over tighten them. :) Upon inspecting it I noticed it didn't sit completely flush with the surge valve diaphram. I even swapped surge valves, tried RTV, etc. Other people where having the same issues around the same time...bad batch of them.

Also if you HKS blew off in vacuum (I assume you had the HKS) it needed to be adjusted. My Greddy only vents after 0 psi like it should.
And I really don't see the logic in the placement or having to still use the stock surge valve...the entire system is pressurized either way. Even more..the turbo is already pushing air to the throttle body right where the bov is, so instead of it traveling back and then venting it vents off right where the pressure point already is. I think it was just easier for mopar obviously integrate the bov in the turbo housing. Like I said I don't think it matters. Running both would be just fine too and you'd just have a more quiet aftermarket bov. I think it's completely fine being at the throttle body plus it reduces the length of the vacuum hose you use so you don't get bov lag thus resulting in surge in that case. I think the sole fact 700+whp SRT's use the bov in this location says something in itself. Every single aftermarket turbo requires a aftermarket bov...don't you think if this was a huge issue they'd integrate a surge valve in aftermarket turbo housings like the stock TD04 turbo? I've run as high as 27 psi and have zero issues with surge on my blocked off Stage 3 turbo and I'd definitely hear it if I did.
I just suggested he blocked off his stock recirc valves because I assumed he got this HKS for the sound as it does nothing for performance. With that being said it'd be much louder if he blocked these off.
Back on topic I'd like to hear a vid...I highly doubt though that the wife would ever want a loud bov on her car. It'd probably drive her nuts! lol

It looks easy to install.

I have been looking on e-bay for one and what would be the different in the HKS model and the one that look the same that are universal?

I have all ways wanted to ad one ever since I bought my Sho. I have just been waiting for one made for the car.
