eckseleven Posted November 13, 2015 Author Share Posted November 13, 2015 Getting tuned now. May have an issue that we're hoping is something simple. Car is hitting boost cut very easily. Boost controller isn't doing its job OR the waste gate can't open. I've been told that they've seen that with some divorced waste gate downpipes. Since no one else has reported this I'd be surprised if it was the dp. Sent from my One using Tapatalk Link to comment Share on other sites More sharing options...
GTEASER Posted November 13, 2015 Share Posted November 13, 2015 Swannee225 had a wastegate issue, but that was after he was running an 18g turbo. He had no issue with the stock turbo and DP.

dwduston Posted November 13, 2015 Share Posted November 13, 2015 I have 2010 Legacy FT currently @ 117k. Have maintained well and never did any mods. All stock. Went catless last week with new Invidia downpipe for first mod. Seems to be a little quicker from the start, but opens up significantly stronger. Any advice for next mods? Also looking at replacing all struts in the near future. Link to comment Share on other sites More sharing options...

Please see some of the other threads and stickies here regarding suspension and "what you did to your 5th Gen today".

eckseleven Posted November 13, 2015 Author Share Posted November 13, 2015 So it's not the boost controller or anything related to tunning. It's either the WG actuator or the flapper can't physically open due to a blockage. Car is going on the lift for further analysis. Grr things started out smooth...

eckseleven Posted November 13, 2015 Author Share Posted November 13, 2015 Update - they hooked a hand pump to the line on the actuator and can hear the flapper hitting something. DP coming off for inspection. Link to comment Share on other sites More sharing options...

Sent from my One using Tapatalk Is it throwing a code at you? If i step on mine in 4th gear no matter what rpm I'm at boost creeps all the way up to 24psi then I get a fuel cut and p0108 Manifold Absolute Pressure High Input. My tuner recommended a 3-port, so that and TMIC+charge pipe are going in on Tuesday. If it still creeps after all that then I'm thinking porting the turbo will be the next course of action.

s2baru Posted November 13, 2015 Share Posted November 13, 2015 you definitely want to chop a hole in the heat shield around the whole waste gate rod where it connects to the hot side. And swannee also chopped off the last few threads on the rod itself because it can be an issue. Link to comment Share on other sites More sharing options...
Starks Posted November 13, 2015 Share Posted November 13, 2015 I'm definitely interested in this dp so I'm watching you guy's progress really closely. If you could, please note potential issues you guys are seeing with the install and tuning. I'd like to know what I'm getting into.

eckseleven Posted November 13, 2015 Author Share Posted November 13, 2015 Would it be possible to see the rod or where there could be interference with the heat shield with everything installed? They aren't seeing anything wrong so far. DP is still suspect and it should be off soon. Link to comment Share on other sites More sharing options...
eckseleven Posted November 13, 2015 Author Share Posted November 13, 2015 Alright, confirmed it's not the rod. Waste gate is functioning properly. It looks like the flapper is hitting the main exhaust exit of the DP. I've asked them to see if there is any wiggle room to shift the whole assembly a bit to try to get it to clear. Not many options if that won't work. Could possibly drill out the mounting holes on the flange to make room [emoji53] I'm surprised no one else had this problem.

GTEASER Posted November 13, 2015 Share Posted November 13, 2015 Interesting. Have them take a pic of where it is hitting. GTEASER's 2012 Legacy GT - Sold GTEASER's 2009 XTeaser - Sold GTEASER's 1992 Legacy SS - Sold Link to comment Share on other sites More sharing options...
eckseleven Posted November 14, 2015 Author Share Posted November 14, 2015 Well it was a rough day and I wish I had some good news to share after it all but I don't. After they removed the DP, inspected it, and reinstalled with it pushed as far over as possible (there was basically no wiggle room) things appeared good. The flapper could open like normal. So they got it back on the dyno to finally begin tunning. Then after a few pulls, something goes wrong again. This time it appears the flapper is stuck open. Car won't build boost beyond waste gate spring pressure. So the theory is, is that when things warmed up enough, the tubing that extends in to the housing expands just enough to catch the flapper. I'm going to contact Nameless to see how we can proceed. I ended up leaving with a temporary map so the car is at least drive-able. Big bummer though.

Fischbach31 Posted November 16, 2015 Share Posted November 16, 2015 Has anyone else had this problem while installing the dp? Link to comment Share on other sites More sharing options...
eckseleven Posted November 16, 2015 Author Share Posted November 16, 2015 Sorry, haven't had a chance to upload pics. I know you all are eager to get more details. I drove the car yesterday and after getting back home and turning it off, I heard a loud "PING" a short time later which I can only assume was the flapper freeing and snapping closed as everything cooled. I'm expecting there to be a mark on the DP where the contact point is but obviously I'll have to get everything apart to take a look. Maybe I can snake a camera up there... So for some good news, even with the temporary tune, holy balls does it have some low end punch. I thought the stage 1 protune was good. Can't wait to see what it will be like when the issues are resolved. My clutch is holding so far Link to comment Share on other sites More sharing options...
