Hi guys,just fitted a garrett gt 29 to my P1,which i bought s/h,there was a water pipe missing from the left side of the turbo,so i got a straight banjo water pipe which sits facing up then has to loop round back down to the water feed pipe from the block,anyway,just been for a test run and first off the turbo sounds really noisy ,like a supercharger,and wont boost above 0.8 bar,(feels fine upto this and no smoke),went straight back had a look under the bonnet and it was extremely hot like puttin your head in front of a furnace,also it sounded like the water was boiling up inside the turbo ,could i have an air lock?,or is the new upward facing water pipe no good?,any help here guys im stressed .

 

Air lock ? A loop like that will be bad news, did you get it checked over before fitting ?

I have taken the water off from the turbo and started the car and there is NO water coming out the water feed pipe ,should there be some water pressure there ?,if i blow down the header tank water comes out fine
