ok just finished my setup and cranked over the motor, runs good but theres a prob the turbo is making no boost!! I've checked over all my charge pipe connections they all look good. The only thing I can come up with is my "downpipe" my real downpipe isnt made yet could this be y i'm not making anyboost?

Here is my exhaust



here is my setup

help!

you drove the car around, right ? If your not boosting you have a charge pipe leak, or a severe hole in a pipe. the exhaust wont make you not boost.

Is the wastegate on there? I just can't see the arm as it would be in the back, if it's on there, not sure why you wouldn't be seeing boost.

LostCRX

you can easily find all the leaks using air compressor or even an bike tire air pump. You're gonna slap yourself silly and ask why you didn't do this before.

hulkhb

You can see it in the second pic, its a internal wg. its diagonal from the drivers headlight.

If its done right i dont think you'll need the bike pump, lol.

i just took the charge pipe going into the TB off and reved the engine to about 3k and I could feel the pressure form the turbo blowin air out of th pipe WTF

the wastegate is shut also

Hoosier Daddy

You did drive the car, right? Your boost gauge isn't going to read boost in neutral.

MikeMAN

yea, you must be in gear to make boost and actually put a load on the engine

I really don't think the bov would be loud @ 1psi.

Is your boost gauge installed correctly?

How did your car feel? Did it feel like you were boosting?

Tad

is your wastegate set to stock boost?

if so you should watch out, i'm pretty sure thats 9psi,
so when you do get it boosting, make sure you dont go killing your motor or something.
whats your engine management setup?

If the wastegate is turned down some, mabye its just turned down too far,
remember the more you lower the boost the logner it'll take to spool

its the stock wastegate i'm running the vafc hack and my enine is runninglike **** right now but i think some of it is due to having no exhaust

-[95cxhatch]-

bumpage i need help

EJ1 wilcox

What kind of turbo are you running? If it's used are you sure it's spinning like it should be?

If the wastegate is cool, the charge piping and intercooler have no leaks, it must be the turbo?

I don't know, that's all I could think of

-[95cxhatch]-

turbo spins fine maybe i have a **** wastegate

MikeMAN

when you were boosting did it feel like a substantial increase in power? or not really anything..besides the noise?

i would check ur boost gauge, if it DID feel like a substancial increase.

i tightened my bov some and my boost gauge will spike up to 4psi now but it dosent really feel like that much more power i overtightrend my BOV and pulled the stud out of the top of it DAMMIT its not my day

dont worry dude, you will get everything squared away...my car has been a bitch lately too

mike

thanks man the only thing i can figure out is that it has to be something with my wastegate. I'm going to wait until I get my downpipe mounted up my neighbors are probly pissed off at me as it is. my car is REALLY loud

hotintegranights

im in the same dilema, just finished putting on the downpipe and still no boost

greekspeed

a common problem on dsm's that have internal wastegates on their stock turbos is that the pin that holds in the actuator arm for the wastgate comes off and the wastegate just stays open, not allowing the car to boost...

this happend to a friend of mine with a stock turbo 91 tsi. he jsut replaced the missing part so that the wastgate could not open freely (with out sensing boost), and the problem was fixed.

EDIT: looks like you might hae already checked what i sugested.

might be a dumb question... but do you have a gasket inbetween the blow off valve and charge pipe?

-[95cxhatch]-

yea I have a gasket between the bov and pipe, the pin you are talking about is it the cotter pin that holds hte wastegate arm onto the flapper?
