Just noticed that my RRC with 200tdi has a restriction ( flattening of the hose on two sides) in the hose going from the turbo to the intercooler. It is definitely built in, not a problem with the hose.
Could some knowledgeable person throw some light on this?
Is it meant to be there? Why is it there?
What would happen if I fitted an unrestricted hose with a full bore all the way along?
