Pop No More Boost

[russ123]

hi ah just wondering if anyone know's if a turbo cars running fine but not building any boost at all as in gets to the 0 on boost gadge and don't move any more is there anything else it could be apart from a busted turbo? it idle's fine,drives fine no smoke just no boost at all thought it could have been split hose but it's getting no presure at all, i know i'm probly graspin at straws but not looking forward to telling the missus "hey guess what i'm spending more money on me car" lol

Might be something simple like the wastegate is stuck open ?

i think if there was a vac leak or the wastegate stuck open it would still build some boost

or at least half attempt to go past zero

it would just be laggy and sluggish

if the exhaust wheel is toast, then you will build 0 boost pressure, absolute zero, as the compressor wheel is only driven by air induction, and not forced from turbine pressure

Just check before you go drop a "g" on a new turbz.

yes the definitive way before you spend any money is to drop the exhaust and visually inspect the exhaust wheel

its the only sure fire way

then you can be sure the turbo is toast

if the exhaust wheel looks ok, check the compressor wheel
