TurboSmart EM BOV

[Jburns1122]

Anyone tried bov block off plate for the flutter sound? and do they throw CEL codes ?

Might sound similar

That sound my friend is compressor surge...no Bueno. A quick way to drastically shorten the life of your turbos

So, what it sounds like to me is that an aftermarket BOV is for nothing more than sound, UNLESS you run a Tune......correct?
Doesn't hold any higher boost without a tune, correct?
Any dangers caused by running an "open to atmosphere" BOV due to water or debris infiltration when off-roading?

Curious to learn more. Thanks.

If you're staying stock, never off-road, or are not hard on the truck...I would call an upgraded valve a maintenance item if anything. I'm already concerned enough with all the plastic on modern engines...If I could eliminate as much of it as possible I will. I'm already running an upgraded intercooler and valve, switched to silicone joints wherever possible, and am using constant tension clamps over the factory items.

A lot of people like the sound, but I get not everyone does. The only other benefit I would say is worthwhile besides the added responsiveness and durability is the fact that valve vents to atmosphere. For those of you who don't know, the factory Crankcase ventilation system in these cars vents engine blow-by back through the intake system (This is essentially oil vapors and moisture back through the intercooler and back into your turbos...yay emissions devices).

My observations are this...in humid climates moisture is a big issue in these intercoolers, and I think Ford actually admits to knowing/observing this too because, on a lot of EcoBoost vehicles, the intercoolers have block off tape to bring intercooler temperatures UP...therefore reducing moisture in the intercooler by making it less efficient (warmer)...some aftermarket intercoolers even have drain plugs because it can be a lot. Before I had a blow-off valve I would have to empty my catch can EVERY oil change. Now with running a valve for the past year on my own truck, little to nothing comes out of my catch can anymore and oil build up in the charge pipes is greatly reduced...nearly eliminated. Over the long run, that translates to less oil gunk in the intercooler and in the turbos...not to mention the valve itself would probably outlast the engine compared to the factory unit.

As far as off-road debris and water...I've never had an issue
The valve location on these trucks is tucked away pretty good and since it only opens a few millimeters with heavy air pressure coming out I can't imagine anything getting in there....obviously don't go fording a river and revving your truck while you have water up to the doors (at which point I'm sure you'll be facing much bigger problems anyhow). You would want to stay on the throttle in that scenario as it is to keep water out of the exhaust system too.

Hope this helps.

Only benefit is going to be if yours is leaking, or if your tuned for more boost, and your oem is leaking. That and sound, if it tickles ya.

in theory it shouldn’t be a problem offroad, as it should only open when it is venting out. But if I was into water crossings, id probably stay with the sealed system.

JBurns beat me.. what he said lol

I agree from the video that the compressor is NOT being spun in reverse from the trapped pressurized air...

BUT pressurized air being forced back against the compressor blades DOES put severe stress on the blades & bearings over continued use...especially over the course of thousands of throttle actuations...

Simply put, just because the throttle plate closed doesn't mean you instantly came off boost...if you run 25 PSI of boost, you're still going to smack 25 PSI back into the compressor...

Unfortunately, Car throttle isn't exactly an academic automotive source... Just an FYI..do some more research and you'll see what I mean

Thanks, but what about all the cars out there that are made without BOV from the factory? if it is that severe they shouldn't last either

A lot of modern vehicles use a combination of the throttle body position and the variable camshaft positioning to vent off excess boost pressures via the engine (essentially positioning the intake camshaft in an open position to bleed off excess boost pressure: BMW and Infiniti do this for example). These systems are used in combination with the newer electronic Internal wastegates of the turbo as well to monitor boost pressures via the ECU...and they can react faster and more precisely than ever before...this, however, is not the case for all vehicles with electronic internal wastegates.

Did you have a specific vehicle in mind you were talking about? I'm talking about the F150 and many other vehicles not utilizing these technologies

How does the sound from this compare to the VTA mods we’ve been doing? Sound is all I care about.

I never did the vta mod to my factory bov, so I don't have a comparison. I will say that it is pretty loud when I've built boost about half way on the boost gauge and promptly let off the throttle. I can hear it clearly with the windows up, with window down it's rather loud and sounds like pressure release on a semi air brakes system. Just going by the sheer size of the valve and opening alone and the fact that there is no expansion chamber like on the stock BOV, it has to be louder than stock.
