GT2052S project thread number three

Bit of a bodge but it might hold get some chemical metal, mix a small bit of that up and but it on wastegate arm leave it long enough to set solid then try it worth a go seen as you haven't got a welder.

Or another long shot is ask on here see of any one local to you has a welder might be able to help you.

On your comment about doing it for £100 my build come to just over £100 but obviously I have the tools to hand, but we won't start that again, just say it is possible to do it if you have the tools at the ready.

Right, got out and jacked the car up, took the intercooler off and the engine off it's mounts.

Removed the inlet mani and ran the car without the inlet mani so that I could see the exhaust mani and observe for any blowing, but there wasn't any. Also checked the tightness of the exhaust mani studs and they were all as tight as I had left them. So there is no exhaust escaping from the head to the mani.

When the motor was running I observed the turbo charger and it felt like there was a nice strong blow coming from it even at idle with the boost pipe off.

I tried pushing on the wastegate arm and was able to move it a few millimetres and it made an immediate difference in the air pressure coming out of the turbo. So it seems that the flex on the wastegate actuator (as it is only held on by one stud) is allowing the wastegate to open very slightly, that is the only possibility I could think of, since I can move it up to a point with my finger or thumb and it does seem to make a big difference.

I could also experiment with removing some of the shims from the wastegate although these were added originally to make the actuator more level with the wastegate arm because at the angle it was I couldn't tighten it down without the wastegate staying slightly open. Maybe I can find a sweet spot. But first I need to chemical metal to set so that I can get everything back together again and confirm my theory

Just to check, is this the correct arrangement for the boost controller:


The pipe comes off the outlet in the compressor housing, goes to the ball bearing side of the controller and then the other pipe goes from the other side of the controller onto the wastegate actuator.
