hey all

as topic, there seems to be something wrong with my car.

when i step on the accelerator, the boost just kicks off to wherever itwants. its like i got unlimited boost or something. the other day it was peaking at 1.9bar. the only mods i have is a pod, exhaust and bleed valve that was set at 0.9 bar. now i've shut it off and it ran 0.6 for a night, but now its going crazy again.

are there anything i should be looking for? would i have damaged the engine in anyway? the only thing that did happened was the intercooler pipe poped.

any help?

Broken wastegate actuator... keep it off boost till you get it fixed or you will trash you motor.

think I saw this on the 'gsr forums' ?

number of possible causes.... a few listed below:
1. knackered turbo actuator...change & see
2. boost creep.
...port the waste-gate and fit a bigger flap
or change the housing for a custom made item
3. don't reconnect the bleed valve
best to use a Dawes device/ other ballbearing & spring product
or fit an electronic boost controller
4. check all boost and vacuum pipes
5. check the boost solenoid which is situated under the battery tray
