jholder Posted June 18, 2006 Share Posted June 18, 2006 Ok, so i'm confused. I was out this afternoon, and stopped by the local performance shop. I thought, what the hell I'll buy a boost gauge while I'm here. Ended up picking up and Autometer. Fast forward. So I read through several of the posts here, and I think I've got a pretty good idea of what to do. I locate the bypass valve, snip the line and insert my T connector. I run the vaccuum line into the interior by following the wheel well to the gromet that the hood release goes to. Tighten everything up, and I think I'm good to go. So I start the car, not really 100% sure what to expect, the needle drops down to -20 (vacuum, and what ever the hell the measurement is for vaccuum). A little odd I think, but that is probably what it's supposed to do. I wait for a sec, then start to give it some gas, and the needle creeps up just a tad. I rev it up to ~4500 rpm, which should be well into boost territory....and nothing. It's still showing vaccuum... Where did I go wrong, several posts suggested that this was the most common mounting location. Did I tap the wrong line? Link to comment Share on other sites More sharing options...
LivNLegacy Posted June 18, 2006 Share Posted June 18, 2006 sounds like you didn't go wrong....you wont boost when just revving teh motor....go for a drive and check your boost readings...you should be fine...

phoenix96 Posted June 18, 2006 Share Posted June 18, 2006 If you were giving it gas while in neutral, that's your problem. You won't make boost unless you're in gear. phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...
jholder Posted June 18, 2006 Author Share Posted June 18, 2006 Quick responses, you guys rock. I am a n00b. heh. BRB. lets go see. Link to comment Share on other sites More sharing options...
Legacy05 Posted June 18, 2006 Share Posted June 18, 2006 and -20 is just fine, mine sits like that at idle as well Sounds like you hve it hooked up right. Link to comment Share on other sites More sharing options...
jholder Posted June 18, 2006 Author Share Posted June 18, 2006 It worked! It looked like it only hit about 10psi ~5000, but of course then I had to look up real quick (in first). Ok, two questions. 1) Does max boost change depending on gear? 2) Where can I get a longer length of that vacuum line? I dont see how people make it to the cubby with what the manufacturer provided. Thanks alot guys. lgt.com ftw. Link to comment Share on other sites More sharing options...

jholder Posted June 18, 2006 Author Share Posted June 18, 2006 oh, on a side note. If the car is shifted into gear, and the clutch pedal is down, will it make boost? What is being read to keep the turbo from spooling up? mph? some shifter based switch? Thanks again. --james Link to comment Share on other sites More sharing options...
jholder Posted June 18, 2006 Author Share Posted June 18, 2006 I never went above 40. I just wanted to make sure it worked. IBhecomesbackwithaticket Link to comment Share on other sites More sharing options...
phoenix96 Posted June 18, 2006 Share Posted June 18, 2006 Max boost does vary by gear. You usually won't reach it in 1st or 2nd. Stock boost peak is supposed to be 13.4psi. phoenix96 2006 Legacy GT Ltd · 2011 Outback 3.6R Ltd · 1992 SVX 2006 Outback 3.0R VDC · 2009 Forester 2.5X 2002 Outback VDC · 1996 Outback 2.5L · 1986 GL-10 Link to comment Share on other sites More sharing options...

BLACKonBLACK Limited Posted June 18, 2006 Share Posted June 18, 2006 nope i get 13psi stock (could be 13.5 but it only displays in full(1,2,3,4 not .5) increments) Link to comment Share on other sites More sharing options...
Guest *Jedimaster* Posted June 18, 2006 Share Posted June 18, 2006 Assuming stock, you won't get full boost until 3rd- that's what happened with mine. Link to comment Share on other sites More sharing options...
mccorry Posted June 18, 2006 Share Posted June 18, 2006 The stock target boost is 13.4 psi...... Link to comment Share on other sites More sharing options...
TSiWRX Posted June 20, 2006 Share Posted June 20, 2006 Brother mccorry gives the easy answers in post # 5 in the following thread, but if you're interested in knowing more, come along for the ride with me, through post # 4. http://www.legacygt.com/forums/showthread.php?t=36572&highlight=boost ---- Yes, your boost level will vary by gear - and remember, even then, it's a boost "target," you may reach the target, or fall short, depending on many different factors, both ambient and vehicle-related. Depending on the accessories you may be running and ambient conditions (as well as road-conditions, if you're, say, using engine-braking), your vac. will vary around the -20 PSI mark. 5EATs can build boost "while stationary." Brother Keefe ("Xenonk") has described in past threads the technique of "neutral revving" to build a very limited amount of boost in 5MTs. <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
jholder Posted June 20, 2006 Author Share Posted June 20, 2006 In first through third, at about 62% throttle, I'm seeing the needle _jump_ to 10 psi and stay there. It's funny, if the max boost (13.4psi) kicks in 4th, you've got to be doing well over 70 at that point. thats hauling ass. I really can't wait for October, and brisk weather. heh Link to comment Share on other sites More sharing options...
