Blow off valve?

[mirel904]

Anyone know if there is a blow off valve for our powerboost? Or if one is being developed? Would be sweet to hear them turbos louder like you can on the ecoboost

Think you need a subaru for that

They make an external waist gate bov.

Just putting an aftermarket intake on there will let you hear it significantly more. I had one on my 2015 3.5 for a little while and you can really hear the turbos and blow off quite a bit more.

Been there and done that with Legacy GT 5 EAT wagon!

The powerboost has an electronically actuated bov. You can make it vent to atmosphere very easily. There are a lot of YouTube videos showing this.

you can also change the bov from electrical to mechanically actuated if you would like. To change the sound. There are also YouTube videos showing this.

Any links to these videos? I can only find ones for the ecoboost.

same parts as eco boost. Just make sure it’s the relatively same or similar model year.

Install a whistler tip. Ask Bubb Rubb for details

An intake is usually a better play. More turbo sound, and you'll hear the diverter valve much more.

I'm not sure if our trucks are similar to other turbo vehicles, but I'd avoid venting to atmosphere (VTA mod). On my last turbo car, the excess boost was bled through a diverter valve (like a blow off valve, but it diverts the bled air back into the intake). In my case, the ECU followed tables to determine how much air the diverter valve diverted back into the intake and then used that to set the AFR. Wasn't a huge deal, but the car did run pretty rich during shifts.

I don't know how Ford designed the diverter valves for the ecoboosts, but it's something to think about.

I bought the turbo smart BOV for my ‘21 2.7 f150. Sounded great and worked great for about a year. Then the problems came. First every now and the it wouldn’t open to vent and just made the factory muffled noise. Then I started getting engine codes for the diverted valve. I removed it, and took my oem divertervalve and cut the huge can muffler/baffle off it, installed it so it’s pretty much just the electric valve, and it sounds the same if not better than the $350 BOV I purchased. Cheap alternative

Any experts know if the '21 ecoboost works using preprogrammed tables of air diverted back into intake? I am not an expert but, I'd expect the diverted air may pass by an air flow sensor.(?)

Separately, I've been interested if installing a BOV reduce power on subsequent revs if that normally-recycled air is vented instead. Again, not an expert - just leaning. Thanks!
