Help... No Boost

[dragracer]

Car was running fine , boosting up awsome, all of a sudden NO BOOST at all, played with the boost controller, nothing, can not find any vacum leaks, you can here the turbo working great, Has a HRC 20, what could it be. Please help.....

this is kind of dumb but did you check your turbo induction? and did you check turbo for shaft play. did you check your manifold maybe it has a gash or leaking someplace does the car smoke?

also did you check intercooler couplings? that happened to me boost, boost, shit no boost

It is definitley a big boost leak. Do a boost leak test. I had the same problem and it turned out my gasket on my intake manifold was bad. Thus no boost

1. Tell us more about what the boost gauge is telling you, no boost is very general, need more info.

2. Check the turbo for in and out, side to side shaft play, make sure the turbine spins freely. Check the LICP and IC for oil.

3. Make sure the actuator arm has not popped off the wastegate lever.

Good luck.
