Lots of boost

[denty225]

From day 1 my car has been running lots of boost. I've been driving it very steady because of this so I don't blow anything, but I can't get to the bottom of it. Ive replaced the head cos the plugs threads were stripped, and all the pipes seemed to be in good condition when replacing. All clips were replaced too. I've fitted a replacement actuator but still have the same problem. The boost will go off the dash gauge easily without full throttle! Where shoudl I look next? I want standard boost!

Any idea is welcome.

Do you have any sort of bleed valve on the engine?

If not do you know how much preload is on the actuator?

[Ash-Lee]

Is the actuator mechanism jammed shut in anyway? Can you move it by hand?

[denty225]

Mark. No and I don't know!

Ash. Yes both actuators can be moved with a bit of effort.

actuator pipework all ok and correct?
what carb top have you got?
get some pictures up

Mark. No and I don't know!

How much did you have to move the actuator eyelet to get it to fit over the lever on the turbo?

[denty225]

Errr, I will get some pics up tomorrow

Finally remembered to take some pics!




See owt wrong?

The pipework looks ok, i bet preload on the actuator is too much. Take the actuator arm off the wastegate lever and lengthen the rod abit, that will reduce the boost

Err, I dunno. You got an uncut top pipe? I might do swapsies.

[dj_craig_]

no sorry mate.

[denty225]

No probs, if I can sort the pipe out you can have the DV. I hate it!

I have a length of 2" alloy you could use instead of the T piece.
