i just finished putting mt setup on and im not getting boost.
I have a blitz tt with the built in boost gauge when i drive it has a vacum of 70 at idle then drops all the way to 0 but doesnt show any boost. I also cant feel a diffrence i can hear the turbo spinning and i can see it. I have a turbonetics waste gate and a garret turbo. I have all the vacum lines hooked up right. I got the lines going from the boost controler to the top of the waste gate. Any help would be appreciated

 

I think i have my blow off valve connected wrong is it supposed to be from the manifold to the blow off valve or from the turbo housing?

 

up

 

Mine is connected to the manifold, just check and make sure your charge pipe is clamped good and no air is leaking between the turbo and manifold.

 

my friends car... it's always gasket b/t manifold and turbo. replaced it 3 times now, only had the car for 6 weeks. but then again it is a VW

 

My blow off valve is open at idle is that correct im also running it with no exhaust on the down pipe wouldt fit could it be this also does it need back pressure for boost

 

There is vacuum but no boost.... I'd start with checking wastegate then BOV.

The way I set my BOV:let the car idle and put a piece of paper(long enough so that it's flappy/flexible) in front of the BOV outlet set it 'til paper barely gets sucked in. BOV shouldn't be all the way open when idling.

Having an open down pipe actually gives you slightly more boost so I wouldn't think that that's a problem.

I hope what I said makes sense to you.

 

hey thanks for the help i feel retarded i didnt have my down pipe on cause it wouldt fit so the waste gate wasnt working i guess so i was running it open turbo but i cut my pipe to make it at least bolt on and now everything ia fine it pulls really strong

 

have fun.

 

yeah im really excited i cant wait to hit the track

 

how does not having a downpipe affect the wastegate?

 

i guess the flapper valve neeeds to be sealed or something

 

interesting. It's weird though cuz I know of some dumbass that molested a perfectly good saab and is now trying to sell it with a broken 15t turbo. Back on point though, he was driving without a downpipe and didn't have a problem boosting to 22psi...until the shaft snapped in half.

 

damn i never heard of that before well i got my exhaust welded up runs like a champ idles like stock getting it tuned tonight by tomdata

 

well glad that we could help

 

Yeah i got my car tuned monday it feels like a whole new car it idles better than before and pulls hard...
Tomdata did the tune koo guy just gotta stay away from the leftovers haha

 

Congrats!!

you guys are so lucky in the States. I mean the fact that there are tuners you can trust/rely on and tuners you hear about that are good. There are a few tuners in Canada but really pricy and cocky. lol So I do everything myself.
