Found out that i`m missing a restricitor effort in the pipe between the compressor housing and the T-Piece, causing me to run much lower boost than i should be. Now i have the part numbers for two different sizes, just not sure which one i need!

22326AA010 - 1mm

22326KA120 - 1.2mm

 

1mm.

 

I didn't think they went to 1mm until 05'. I may be wrong.

 

I`ve ordered both now, it`s running at 10psi at the mo so no where near...

Quite embarasing that i didn`t notice the lack of power till i fitted the boost gauge, suppose it comes from driving nothing more than a Peugeot Partner for six months...
