Ok so I saw on a thread here a link to the veloster forum where I am guessing they are bypassing the Bov solenoid for some reason and saying that it helps with boost. I am still trying to figure out how this helps and if it is even a good thing to do on our cars. Right now I get a code once in a while for a turbo bypass valve (mechanical). I am guessing it is my bov or am I wrong and it's the soleniod that controls it? The dealer has no clue what is wrong but I asked if they will just change the Bov to see if that is it and they said it can't be since I just bought the car and it barely has 300 miles on it. The place is saying it is probably over boosting and throwing that code.

So would this be a good thing to try and see if it is the solenoid crapping out or the bov? I was thinking of using the line that comes from the manifold that goes to the soleniod and hooking that directly to the bov.

Just thought I would ask this because it seemed interesting

Oh OK I was just curious about it. I did take the tube off the bov and capped the onend on the intake and I hear the bov when it is parked and slightly reving it but when I drive and let off it sounds like made the waste gate is opening and not the bov. After a hard pull I let it calm down then I hit it again and hear boost coming from the bov and then like a pop and then it starts pulling hard like the bov was stuck.

Is there a way to check the stock bov to see if it is moving freely? If there is I want to try it.

Also I have the line from the manifold to the solenoid zip tied at the manifold because it would come off if I hit full boost

Is it possible to have picture off how the solenoid is conected after the mod? Is it just blocked? When you put a new bov or boost gauge, do you still need the T on the tb?

Whole shot just different. View attachment 316
I removed the CAI and unbolted the bracket to give a better visual.
What BOV are you using?? Just going off of My optima and all the newer style vehicles most BOV dont react quickly enough with ECU timing and boost control, in return causing compressor surge from the BOV not closing quick enough. This is why i recommended the synapse. It was the only one that didnt give me long term problems with my optima. ITSJUSTME i am not in any way dissing or saying your wrong in anyway i am just looking for you input on this. And just speaking form experience with my optima and also from seeing all the others having issues with it

I can tell you right now from reading all your post you are a very smart person. You know very well what you are talking about when it comes to this application.
I come from the world of N/A before my optima. Plus eco boost style vehicles are not like other forced inducted production vehicles that are race inspired and not focusing on MPG

more boost is more stress on the internals is the only thing that comes to mind... but the minimal PSI gain this does may not have any adverse affects sense factory turbo cars usually have forged internals and can withstand quite a bit of punishment

You can do it but your stock bov will be crap after a few good pulls.

@Knee had mentioned that we don't have forged internals when I asked him. I will eventually go forged later on down the road. But for now I will enjoy the stock ones with 9k on them

if its true, i wonder why kia wouldnt put forged internals into a car thats going to be seeing boost for 100k+ miles

someone was probably calculating the cost vs warranty claims

From what i am reading on the vt forums is that we dont. There are forged rods and better pistons for us now though

Probably because this isn't a race car
And also it changes the price of the vehicle
This is an Eco boosted vehicle
It's not races inspired is mpg inspired with the added benefit of some quality power

I call b.s! Kia has a race inspired car big time here! Why else would they give us a crazy 1.6 turbo? Lol!

Well I hope you are exaggerating
This is not a crazy 1.6l turbo
Neither is the 2.0t
Race inspired no
But if they thought people wouldn't mod this car they are crazy

I seen that on VT forum. Just wondering when he was planning on dropping the forgies in. After that he's gonna be ready for a turbo upgrade and pushin 350whp baby! Just kidding, could be close to that though. I would imagine he would need some kind of piggy back system when going up to 300whp+. Not sure though. Can't wait for Knee to school me on this stuff.
