Hahaha, I think I'm about in the same boat as you. This race shop I'm talking to is coaxing me into this tune. I'm positive my wife isn't going to like the price. But man would I like to have the face to face and confidence in their ability. Sent from my SM-G935V using Tapatalk

Yeah, I've already been looking for tuners. I'm considering tuning alliance, another guy suggested mtune as well, even contacted circuit Motorsports in Orlando. The latter is super pricey compared to other options. Sent from my SM-G935V using Tapatalk

So I've had about 45 minutes behind the wheel. So far so good I believe. One thing I am noticing is many more pops from the exhaust between shifts and off throttle. The ots must be super rich. I'm trying to get some logs now. If I gather some will you guys take a look? What are you normally logging? Sent from my SM-G935V using Tapatalk

Appreciate the research and help! Out of curiosity, where would we source the flapper? Sent from my SM-G935V using Tapatalk

Well I finished the install this evening. It sounds good!! I'll say that. Loaded up the 91 stg 2 map. I'll see how it goes tomorrow. Sent from my SM-G935V using Tapatalk

This whole endeavor has been aggravating. I'm glad I have a daily. All I have to do now is connect the oil feed and it's good to turn over. Almost done, fingers crossed. I forgot about the restrictor plate, I'll keep that in mind. I skipped installing the bpv for now. I didn't feel like dealing with that aggravation. Side note the DP bolts and stuff, as Flegacy suggested alternate the DP bolts to the intermediate pipe. On the one with the dick hair clearance, mate the bolt to the DP first then thread the bolt to it. The intermediate pipe to catback use the supplied shorter bolts from Nameless.

That little clink that you hear is the arm hitting the WGA arm. Its hard holding the camera, the WGA arm up, and moving the flapper all in a go. You can see the scrapes on the outside flapper arm from me playing with it so much. I made sure I didn't feel any interference when I was bolting it up. If it still scrapes when hot then it's a design flaw of the DP. Because I sure took the time to make sure it didn't before hand. If I overboost with the stock bpv then I'm chopping off the DP exhaust channel. Sent from my SM-G935V using Tapatalk

Okay cool. I'll give that a shot tomorrow. I'm also installing the nameless bpv so we'll see how that goes as far as overboost. If it does I'll take it off and see if it persists. Lastly, I took a short vid to verify that I am able to manipulate the flapper without interference. So any overboost encountered isn't an install issue. Not that nameless would care though...

Yeah, the intermediate pipe is on along with the adapter. Which set of bolts did you use? The OEM, nameless, or grimmspeed? And what's up with the DP bolts. On the driver side there's enough room for the nut to thread all the way down but on the passenger side it won't thread all the way down because of clearance on the locking nut even if I flip the nut and bolt. Sent from my SM-G935V using Tapatalk

So to the guys who used the stock mid pipe, how did you mate to the nameless intermediate pipe? The OEM spring bolts won't fit in the intermediate holes, the bolts that come with the grimmspeed adapter are way too large for the DP holes and the bolts that come with the dp look too short. Not to mention that they have no give to them like the spring bolts. What did you do? Sent from my SM-G935V using Tapatalk

Hehehe I liked that one. Sent from my SM-G935V using Tapatalk

Idk, I made that clearance. As far as a different actuator, I'm not going to go that far unless the boost situation stays out of control. Last resort. http://www.forgemotorsport.com/?p=Actuators&page=1 https://www.maperformance.com/collections/wastegates-actuators/products/grimmspeed-adjustable-iwg-mounting-bracket-subaru Yeah...Idk man. This whole thing is aggravating. For this dp to work were literally doing precautions to make things compatible. Modifying the turbo, then maybe modifying the DP, then my thought of altering the WGA. Since I know there's an installation issue I'll mount it pushed and pulled or whatever nameless said. Manually operate the arm to check for clearance. Then if OB happens I'll get to cutting. Sent from my SM-G935V using Tapatalk

I'm going to end with this. IMO there is a design flaw with the dp. If your were to pick this up with no knowledge of this issue you have a high chance of overboost. The reason I believe is because of their directional separator. The waste gate will jam against it if you don't mount it perfectly. And that's completely dumb. The waste gate won't open fully and you'll be over boosting or it will scrape past eventually and be stuck open. This is what nameless was attempting to say when they mentioned move it in some direction. That 1 or 2 mm adjustment could mean the difference between a new engine. And if you're just doing an install that should be as straightforward as it looks and sounds who's really checking to see if their waste gate has proper room for travel? Look at my vid and see how much difference that 2mm makes. Sent from my SM-G935V using Tapatalk

I think they did a fine job. They ported what needed to be ported. They knocked out that large lump, made a straight path, and made a tapered edge to the waste gate. I believe I'm going to also take their advice and cut some out of the DP. I can feel the flapper interfering with the dp. Sent from my SM-G935V using Tapatalk

So I got my housing ported by Boost Labs. Here are my takeaways. First they are an awesome local shop. I couldn't ask for anything better. They ported and media blasted my housing very quickly. #2 they know of nameless performance and were surprised at this situation. #3 they said on their own accord that this is a poorly designed housing. #4 they suggested if there are still overboost problems after this, cut off the circular protruding piece on the DP because in their opinion it interferes with savaging of the exhaust. #5 they wouldn't recommend changing the flapper and opening the hole further because they've seen situations where changing the lever can cause the mechanism to seize once things heat up.

Yup! That one!! Sent from my SM-G935V using Tapatalk

I thought it was the product and the poor customer service in resolving the issue? It seems that people are happy with their handling of the situation. My bad. Edit: (Actually I could share the poor customer service experience my wife had when she bought their bpv for my birthday last year if you'd like another example).

You're really suggesting he buy more stuff from Nameless IN THIS THREAD?! Sent from my SM-G935V using Tapatalk

Oooh! Thanks for bumping this. I was looking into this mod and this thread answers everything. Sent from my SM-G935V using Tapatalk

My thought as well, I was just trying to give it the benefit of a doubt. Very odd. People may be unknowingly sacrificing low end torque using this dp. Sent from my SM-G935V using Tapatalk

I'm definitely wondering if the boost control issue is affecting lower end torque with the use of this dp. Like are tuners opening the waste gate sooner to bleed boost off before it goes out of control. I mean, spool time should be the same regardless right? Sent from my SM-G935V using Tapatalk

Man, that sounds like a headache but I bet you're glad it's over and resolved. Are you planning on doing anymore HP mods in the future or is this the end of it? If you could get your hands on another hotside to correct the port would you go that far? Any ideas as to why the English tune feels less torque in the lower rpms than the ots? Sent from my SM-G935V using Tapatalk

I see now. So just to confirm we're grinding down the red marked areas right? Sent from my SM-G935V using Tapatalk

Wait, I'm not following this. In its current capacity if the flapper was able to open 100%, it can't with this dp. Impossible. The restriction is creating back pressure at the moment. Though minimal, I think we can agree that the angle isn't desirable. It'd be best to be open completely with no resistance for waste gate gasses. Sent from my SM-G935V using Tapatalk

That's exactly it! I know what to do. The Australian member who posted about his install has the right idea. That covered all bases! Sent from my SM-G935V using Tapatalk
