What would cause a turbo not to boost?
If a turbocharger doesn’t produce enough boost pressure, it won’t work. Low pressure can also be caused by leaking lines or gaskets (allowing pressure to escape before driving air into the cylinders, improper filter maintenance, and a worn or sticky poppet valve can also cause this condition.
What causes a turbo to kick in?
It’s caused by the time it takes for the pressure from the exhaust system to build to the required level needed to spin the turbine inside the turbo. Once a turbo reaches the required speed (known as spooling up) it can then begin to and force more air and fuel into the engine.
What should I do if my turbo charger is not boosting?
id be looking at vac lines to the turbo coming from the boost pressure control solenoid. Then id be checking that vac lines to it from the inlet manifold side. if all are ok.. then check for command voltage from the control unit at the boost pressure solenoid. if to no avail check the physical condition of the actuator.
Where to find out if your Turbo is actually creating boost?
Winthrop Harbor, Illinois. Is your throttle actually opening all the way when you have it floored, like visually check it. Where is your boost gauge hooked up, to find out if the turbo is actually creating boost. Also, do the obvious like check all your couplers and pipes, make sure it’s all tightened down.

Where is your boost gauge hooked up, to find out if the turbo is actually creating boost. Also, do the obvious like check all your couplers and pipes, make sure it’s all tightened down. Hopefully it’s not something in your intercooler… :/ The SAFC is useless for tuning while in boost on the 420a, just an fyi. Loading…
How to do Turbo spooling but not boosting?
A. There is only one way to do it right. Compressor cover/j-pipe/nipple directly after turbo—boost controller—wastegate. The “—” represents vacuum line. B. There is mechanical timing and ecu timing. Mechanical timing needs to be set correctly so you don’t damage the car or have it run poorly.
