eckseleven Posted April 19, 2016 Author Share Posted April 19, 2016 A couple exhaust phases for me. Organize how you'd like. I'm at sea level. Originally: Nameless DP + AVO CBE. Easily hit boost cut below ~30F. Would see ~18-19 psi around 40F. Next: Nameless DP + AVO front pipe + Grimmspeed DP adapter + stock everything else. With this configuration could still exceed WG spring pressure by a fair amount at 40F but did not hit boost cut. I think it peaked at about ~16.5 psi. Currently: Nameless DP + AVO front pipe + Grimmspeed DP adapter + stock mid pipe + AVO muffflers. Did not get to test this in the cold but would expect it to be somewhere in between the other two. In all three configurations: stock BCS, stock non-ported turbo, tune set to 0% WGDC. Link to comment Share on other sites More sharing options...

Apexofthevortex Posted April 19, 2016 Share Posted April 19, 2016 It would be nice to see what your max boost is supposed to be and what you are seeing. I have seen my own boost spike to ~18psi on the ots stage 1 cobb tune, on the HWG map, so I guess what I want to be sure of is that it is hardware and not tune/weather related. Which parameter would display what max boost is supposed to be at on the Accessport? Would it be boost target? Link to comment Share on other sites More sharing options...
ripstik Posted April 19, 2016 Share Posted April 19, 2016 Which parameter would display what max boost is supposed to be at on the Accessport? Would it be boost target? Yep boost target is what you want, it will fluctuate with rpm and throttle positions but the max value after a full throttle pull should be your overall target boost limit Link to comment Share on other sites More sharing options...
jackal8788 Posted April 19, 2016 Share Posted April 19, 2016 Which parameter would display what max boost is supposed to be at on the Accessport? Would it be boost target? If you're on a Cobb OTS Stage 2 map, the max peak boost is 17.5 PSI for 93 octane and 16 for 91 octane. If you're on a custom map, better ask your tuner VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...
Apexofthevortex Posted April 19, 2016 Share Posted April 19, 2016 (edited) I don't think theres a way to monitor both boost target and actual boost pressure simultaneously with the V2(correct me if I'm wrong). If that is the case I'll pull some logs this afternoon and upload them here for scientific research. IIRC tuner said target was 18 psi, but I've seen it creep up to 22 when it was really cold outside. Now that its Spring and really hot maybe it will be different Edited April 19, 2016 by Apexofthevortex Link to comment Share on other sites More sharing options...

I have the Q300, Grimmspeed EBCS, stock turbo non-ported. Phoenix is at about 1100' I wasn't overboosting before the catback, now I'll hit 19.5 psi sometimes. My target is 18. I'm hopeful that it can be dialed in with a re-tune since it was fine before. Link to comment Share on other sites More sharing options...
haruichi808 Posted April 20, 2016 Share Posted April 20, 2016 I'm running np dp,stock mid ,and np 5"axel backs ,grimmspeed ebcs, stock turbo and wastegate , on one of the pulls it spiked to 24 psi and hit 395 tq I just ordered a mildly used invidia catless downpipe for 200 bucks I can't afford to put back on the dyno with nameless dp n still have these problems, my car is babied I drive 10 miles a day n ran perfect till install of this dp, there one guy near me with same set up with invidia catless and tuned last year with same tuner and no problems and I'm in Hawaii so I guess sea level up to1500ft elevation On another note anyone ever install this iq dw downpipe from Russia http://m.ebay.com/itm/Turbo-Downpipe-for-Subaru-Legacy-2-5GT-BM9-BR9-/262390344713?nav=SEARCH Link to comment Share on other sites More sharing options...
Zee199969 Posted April 20, 2016 Share Posted April 20, 2016 Looks like the Russian DP has a similar design to nameless's but with a 2.5" instead of 3" My "Build" Link to comment Share on other sites More sharing options...
haruichi808 Posted April 20, 2016 Share Posted April 20, 2016 So I asked nameless for input and this is what I got ekcselevn did u try this There is a very simple resolution - just loosen up the bolts and shift the downpipe forward relative to the car and bolt it back on. It was probably installed pushed all the way to the back of the range of tolerance and was hitting due to that. I don't believe we had a single customer that actually had a part altered at all. The only people with issues were able to be resolved by simply adjusting the location of the downpipe flange relative to the turbine housing. We make the bolt holes oversized a bit to prevent shearing of the turbine housing studs during heat cycling. If the downpipe was even installed centered on the bolt holes it should have no issues.

Apexofthevortex Posted April 20, 2016 Share Posted April 20, 2016 Didn't get a chance to pull a log for you guys last night. I did monitor target and actual boost this morning on my drive to work. Target is set to 18.5 psi and I was actually underboosting a bit, it was 50 degrees outside and I think the highest I saw was about 16.9 that wasn't a nice long pull but I remember when it was first tuned it could easily hit 20+ by about 5k. I'll keep watching it on my way home and try to see if I can get it to overboost again. Link to comment Share on other sites More sharing options...

Absolutely. Everything that can be tried with this DP, has. There are no clearance issues with the DP and the wastegate door. This was confirmed with a hand pump hooked to the actuator.

Zee199969 Posted April 20, 2016 Share Posted April 20, 2016 It'll be interesting to see what, if any, differences there are between the GB DP and the one Swannee was using. My "Build" Link to comment Share on other sites More sharing options...
jojorios Posted April 20, 2016 Share Posted April 20, 2016 so it did come down to the bolts... i had feeling that was the issue So can these ARP bolts be used in some other location (bolt on turbo, headers) or are they pretty much 40 bucks in the garbage?

eckseleven Posted April 20, 2016 Author Share Posted April 20, 2016 So can these ARP bolts be used in some other location (bolt on turbo, headers) or are they pretty much 40 bucks in the garbage? Most likely garbage/paper weight. I'll probably be using them to put my OEM DP back on when I inevitably part out this car. Link to comment Share on other sites More sharing options...
