After Market BOV Recommendations....?

[bpd1151]

Okay, so pursuant the thread on 4DRHTRD's discussion / research / development of the hard "hot pipes"

(see/refer to this thread below)......

http://www.ecoboostperformanceforum.com/index.php?topic=615.15

I would like to introduce a new thread on any product recommendations as it relates to after market BOV's.

Since 4DR recently stated that there is NO performance difference between rolling with two BOV's (I.E. the factory setup) versus a single BOV (I.E. 4DR's new hard hot pipe design)......

I am wondering if any of the members of the community have any recommendations on after market BOV's?

I performed some research on my own, but am still a little bit confused.  :boom:

1st, does anyone know what design are the factory BOV's? Are they "push" or "pull" design?

2nd, what should one be looking for as it relates to after market BOV's?

3rd, it seems HKS is like the industry standard for after market BOV's.

4th, (and this is directed mostly towards 4DR) but what type of BOV should one be shopping for as it relates to the soon to be released hard hot pipe upgrade?

Thanks in advance, for any experiences, recommendations, or anything of the like, as it relates to this particular thread.

I've always wondered about the electronic factory BOV vs the passive BOV you're talking about.  Wouldn't having control of it be better than something static?

It's an electronic BoV, not vacuum actuated at all which has to do with push vs pull

2nd, what should one be looking for as it relates to after market BOV's?

Most of it's brand preference, I like Tial and that's the one I'm picking up

3rd, it seems HKS is like the industry standard for after market BOV's.

I would disagree whole heartedly but if you think there's cult followings for tuners don't even get started on BoV manufacturers...

4th, (and this is directed mostly towards 4DR) but what type of BOV should one be shopping for as it relates to the soon to be released hard hot pipe upgrade?

I will be providing options for BoV's with the pipes!

Stay away from Greddys.

I had a Type S and a Type RS both on my Evo, and they leaked under high boost.  The Type S did sound awesome though.

I was looking at going to the HKS route.

How much was high boost?

I hate to admit it and call me a ricer if you want, but I do want a loud ass blowoff for shits/giggles.

I want one to compliment my "let's pull Storm over every week for tint!" style.

So 4DR.....

If the factory BOV's are Electric, then what, if anything will need to be done on the 'end users' end as it relates to eliminating those, and instead, implementing in it's place, a single, after market BOV?

I guess what i'm wondering is, will there be anything that needs to be done from a tuning perspective? Will the ECM go haywire, or throw a CEL (much like rear O2's being removed and not being programmed off).

Does the ECM even monitor the electric aspects of each factory BOV?

Sorry for all the questions, but I suspect i'm not the only one with them. Maybe just the only one brave enough to present them and ask them.

Thanks once again.

Initially we'll have to follow the ecoboost truck example and leave the factory BoV attached to the harness so no codes are thrown. I'm working on a harness and resistor to be able to replace the factory BoV and not throw a code.
I picked up my Tial Q today for my setup, I'm going to have to figure out what I want to offer but I really like the Tial BoV and I've been using them for years, also if Full-Race trust them for all their kits I do to.

I'll look at offering different flanges for people to choose their own BoV, we'll see for now.

 

[bpd1151]

Well that seems kind of silly.

To just up and leave the factory BOV's dangling around within the engine compartment.

Visual presentation (of the engine compartment) is equally important to me, as is the performance increases.

I may hold off then until your hard, hot pipe upgrade allows for incorporation of the factory BOV's.

Well, at least that's my initial consideration.

I can still be swayed as developments occur.

Have to make the computer happy or you can't drive your car....
The factory bov scenario will take awhile due to having to replicate the factory mount in cad then machining them . You can always take the factory bov out at shows until I get a harness made.

Hell yea! I have turbos and i want everyone to hear them

 

[PopolZ]

I kept the factory BOV but I have replaced the noise generator with a HKS SSQV III. It's quiet most of the time but it will be loud if I'm punching it.

 

[QwikEVO]

Man, if I'm spending that kinda cash on a BOV it better blow off loud as hell LOL

Did we ever get a solution for this? I've got quite a few boosted toys, and I really enjoy having them all have them same blow off (Currently Tial-Q).

These electronic blow offs are just so stupid, and they don't sound good. I hope that these ecoboost stangs will get some of these real shops off their ass and develop some parts for these easy issues.

I am running the TiAL blow off valve for about 6 months now. Make sure you get the right spring though or it will be open at idle. I am using the yellow spring.

I'm very familiar with how a spring operated bov works. My questions were around where to acquire these "Hot pipes" (If anyone even made them for xsports) and if anything was done about the computer / codes.

I don't know whether they are made for the X-port... but on the transverse 3.5TT EB GDI engine the rear factory electric BOV must be left connected regardless of any mods or the engine will throw DTC and CEL regardless of tuning or how many time you clear it... the front can be removed.  The hotpipes made by PPE for Ecopowerparts (now sold through Black market Racing) can be had for either factory BOV or Tial mechanical BOV.  In the mechanical version the Tial VTA is from the IC to throttle body pipe In the electric version the Factory BOVs mount in OEM positions  on the preintercooler hotpipes but are VTA with a large opening for the blowoff.

I am unaware of any dyno or track testing in the Flex or SHO showing one superior to the other as far as performance.  The ease of use in tuning and amount of IC condensation of oil and fuel may be another debate. A catch can solution for the PCV/CC blowby is available from many manufacturers and there are numerous threads here on these.

I am running these hotpipes with factory electric BOVs without a problem.. I prefer the aesthetics (I have nothing under the engine cover just zip tied and doing nothing). and function is great as far as sound (I'm asked by other drivers what that Pffft sound was) and performance (0-60 in 4 sec or less consistently).

VTA, IMHO, is more than just the sound... if you recirculate the blowoff then you send the volatilized oil, etc. that you compressed (from CC blowby via PCV system dumping into the intake air) back for another pass over the turbo blades... This would increase coking of the blades and perhaps increased deposits...at least make it more rapid than VTA... and could result in more condensation in the IC. So I believe VTA actually protects your engine and helps preserve performance in the GDI... In the mechanical version the Tial VTA is from the IC to throttle body pipe... don't believe this location matters except that a catch can is more important if you're worried about sending a gulp of liquid to the engine and it is easier to access when you are changing springs.

I looked at that website previously and didn't see any ecoboost parts. It appears it's under construction now that I look again.

I understand there's no performance benefit, and the idea of keeping the surge out of your turbo's is just good practice at best.

What I hate about E-BOVs is it blows off when it shouldn't, especially under heavy-load like highway driving. My BOVs open while I've got cruise control on and going up an overpass... like.. seriously?

This truck is pretty cool, but I'm used to JDM aftermarket... not domestic 36k warranty- so I'm trying to find a happy medium for a daily driver, a proper BoV will go a long way for me. (Plus it'll match my G35 and jetski ^_^)


EDIT:

Got a youtube video of your ride? I'd love to hear a real BoV properly done on an eco boost motor.
