Question, TurboSmart BOV Kompact Dual Port VR13, no leaks, slight loss of peak boost??

I installed the TurboSmart BOV Kompact Dual Port VR13 bov last night. Seems to be working fine, can’t hear any leaks when in the throttle, dumps when I let off. But I noticed on my Ford Performance programmer that my boost only peaks at about 20 psi most of the time now and it feels a tad slower. I’ve seen 22 once but it used to be at least 22 to almost 24 on every run.

I’ve scoured the Google machine and haven’t found much negative on these BOVs in the Ranger. A couple instances of faulty wiring and whatnot but as far as losing peak boost not much.

Anyone else out there run into this problem?

also, I am aware of alternatives like the Boomba adapter and only want to go that route if the Turbosmart is known to have lots of issues.

Thanks!

When I got my compact it leaked at the o-ring under heavy load. I could hear it leaking. I contacted Turbosmart and they measured some of the o-rings they had on hand and said they were small. They ended up sending a replacement. This was like 4 years ago though

The truck is designed to vent back into the intake. But that wouldn’t impact peak boost. Did you do anything else, like intercooler or pipes?

The computer might need to learn the new bov a bit as well. It no longer slowly leaks off boost like the stocker, this is more of an on off valve. You should experience a higher boost.

Boost also depends on temperature, load, fuel quality, humidity, altitude ect. Plus if its holding better pressure it might not need as high of psi to hit the torque value.

I didn't have the ford tuner when i initially installed the bov, so can't compare... but i don't usually see my boost hit above 17psi. Not sure if thats due to being at higher elevation though (about 7000 ft)... But you've got me curious now so i'll slap the original one on and see what happens

Update - Been thinking about this all morning so had to swap it out despite it being below freezing here... peak levels are unchanged, however the vacuum levels when off throttle are much higher than before. On the turbosmart i'd see about 4-5 psi of vacuum when idling at the light, now i'm seeing about 10 psi at the light which matches to what i get at startup. I'll try to run a 0-60 later, but initial impressions are the throttle is a bit more responsive

Yes I do, I have the Mishimoto intercooler and charge pipes. Apparently this model bov does vent half back into the intake. I appreciate the response, I think It was kind of a false alarm actually.

I got a chance to do a run with my Dragy and you’re right, peak boost definitely isn’t the only factor. My 0-60 was right where it always is and my 1/4 mile was one of my fastest to date.

Appreciate your response! I actually think it was a false alarm. Despite showing less peak boost, my Dragy results as of this morning are virtually unchanged. 1/4 mile it might actually be consistently a tenth faster. Now you have me curious about checking vacuum numbers too, I don’t think I was looking at the big picture with all this.

The vacuum numbers were definitely a surprise for me as well. It might be worth looking at cleaning the turbosmart valve too, i recall seeing notes in the installation guide about periodically cleaning it... which honestly is reason enough for me to stick with the OEM one... but i might clean mine anyways to see what happens.

All i know for sure is mine wasn't performing optimally, and i think it was impacting my fuel economy numbers. I did a quick cruise down the freeway and back (80mph, about 30 degrees out, uphill one way), and overall i gained a whole mpg on my average (which was reset at fill up about 60 miles ago). That right there surprised me quite a bit, especially when i was averaging 16.2 til this drive, which brought me back to 17.2. I'm going to top off the truck and check it at next fill up.

Yeah I saw that too, I think they recommend every 500 miles or something similar, which I found out after install when I was searching about my “lack of boost”. Seems like a lot of extra maintenance even though it’s super easy to do. It’s only been installed for about 2 days though, I just got it this week. Which is another reason I might’ve jumped the gun lol. My mpg hasn’t changed yet but I haven’t reset the average either.

You might have, but yeah check those vacuum numbers

So, just got to work and I looked for it in the parking lot. Are you talking boost/vac? Mines showing -10 at idle. I didn’t search long cause I ran out of time but I didn’t find a vac figure to display by itself.

Yeah i just use the Boost/Vac instead of the straight boost one.

Thats good news. Faster means better. More psi is not always more power. Learned that the hard way back in the day.

Absolutely. This is my first go round with a turbocharged vehicle so I’m learning as I go lol

They can be fun, but easier to break when you go off the deep end. I have always had a turbo engine. We only had 4 NA motors in the family in the last 20 years.

Absolutely lol. I did have a Grand Prix GTP a long time ago that was supercharged. But back then I didn’t have the money for go fast goodies so it stayed stock. Also kind of a different ballgame with a blower.
