Getting no boost at all really.

[shawn1331]

hey guys, I have a redtop sr with a gtir t28 modified to fit on there. At the moment I can't get it to boost. It is under vaccuum like it should be but when I get on it, the boost makes maybe 1psi according to my gauge or less.

I checked for leaks and there is a giant one at the exhaust manifold. It wouldn't even hold air for very long, but would that cause 0 boost?

Wastegate arm was attached and seems to be firm and not opening right away. Turbo isn't seized. I took the intake off and it does spool it but I was thinking with the exhaust leak maybe not very well?

Either the wastegate is bad and isnt able to hold closed. Boost leaking or something. Or the turbo is just shot

I'm gonna put this new gasket on I just got and go from there. My next guess would be wastegate bc the turbo is very clean with no play

Have you done a boost leak test?

I think it might be boost leak.
Or flapper door on turbo fell/broke off also associated with actuator

Boost leak. Check intercooler and couplers.

So i seemed to have hunted it down. Was a combo of things mostly being the wastegate had to be adjusted, and i figured out my EBC is toast after just hooking up back into my IC piping and running straight off the vaccuum pressue. Thanks for the inputs fellas
