no boost on my gt4 st205 Options

[pikey]

hi can anyone help me please! went to drive my car back from my army camp and it had been working fine in the morning. obviously i let it warm up before i give it any kind of boost, at least 1/4 up the temp guage. the car was warm and i put my foot down. there was hardly any power with the boost going to 0 wich is vaccum pressuer i believe. theres a strange whining noise aswell.

ive had the turbo off and its all fine, there was however a little oil in the induction pipe but not much. ive checked all the vaccum and boost hoses and they seem fine. in a nutshell im running a motec m4 pro ecu with 1.1bar boost, 3inch exhaust from the turbo with 2.5inch restrictor so its not overboosting and a few other bits but theyv all been on for at least 6 months with no problems.

so all i can think of is maybe the actuator or a sensor or something. can anyone shed any light or give me any contacts please thanks

There was 77 ST205 Group A Rallye's delivered to Australia.

all have leather interior, manual air con, intercooler water spray, water injection, antilag, headlight washer squirters, factory fog lights, dashlight dimmer control, obviously the spoiler riser blocks, bonnet wing, drivers airbag, sunroofs on 17 of them (of which mine is one), the rest is normal gtfour stuff.


basically they came with every available option appart from climate control.

there might be more but thats all i can think of at the moment.
