last sunday i took the scoob to a rolling road on the way there it did not seem to be boosting as it normaly doe's 15.5psi just seemed down a bit.

had a run and came out 265bhp-252lbft

then monday it had dropped again to 10 psi ?

went and saw Mr.Darley who had a look and replaced the main pipe work from the intercooler to inlet manifold and from intercoooler to dumpvalve!

took the scoob out and it was all back to normal if mot better

right then ??

ok it look's like its the turbo actuator that's gone.

removed dawe's device and replaced standard boost solenoid.

still 10psi on road test.

took the actuator off and had a look at it, then replaced it and took the car out again.
still only 10 psi boost.

disconected the pipe to the actuator and 25psi which is great for me but not for the car

so it looks like the actuator is not closing fully and letting boost escape.

took the heat sheild off again and adjusted the actuator rod to fully in as far as it would go and still only 10 psi boost?

Mr.D said to try and connect the turbo housing direct to the actuator with a single pipe with the boost solenoid disconnected but still on the road 10 psi

also reset the ECU but no joy.

so need another actuator for a TD04 if ya have one hiden in ya garage any where let me know.

Mr.D says the turbo is fine
