Not Boosting

[hoony]

hey everyone,

mate has a stock GTT manual, no mods

told me his boost gauge (stock one) still shows boost at 2.5k rpm but at that amount of revs there is actually no boost at all

he can't feel anything and boost never comes on, says all his piping and wires are done properly and nothing looks wrong

could it be his airflow that's the problem?

actually, he says he LOSES power after 2.5k rpm but the gauge still shows

he's just sms'ing me and i haven't been able to check out his car, anyone have any idea as to how we can diagnose this problem?

any advice would be massively appreciated, cheers!

maybe its to do with the turbine ? maybe the fins broke off and lodge somewhere ? could that be a possibility ... remember Brendan

told me that it happened to one of his friends before ... cant see it until u remove everything ... LOL

[hoony]

i thought maybe the turbo has finished but then why would the gauge still show spool?

his car has only done 60,000 odd km's

thanks Don

anyone have anything else to add?

check for air leaks

[Harry-Hotpants]

lettin us kno where he has his boost vacuum line connected to will help us help you diagnose

It could be that the clutch is slipping under boost?

just because it builds up to VAC doesnt mean the turbo is working fine andy.

alright everyone, thanks for the advice, i still haven't been able to check out his car but he's told me that it was the air flow and that it was fitted the wrong way!?

he said it's all good now, i thought it was a bit strange lol

thanks all!

Hey mate could even be the actuator if thats stuffed it will let the exausst pressure striaght out

it would also explain the no power after 2500rpm probly running up shit to.

check it out

cheers

You just quoted that he said everything is all good now and then you give him an alternative to fix the solution? *confused*
