Question regarding my 110 TD5 with VNT:
I have a snorkel on my 110, one that goes through the top of the wing with internal diameter 2,5 inch.
From the snorkel to the airbox I have a flexible hose reinforced with metal so all the original plastic stuff is gone.
But I have the feeling that the engine is not pulling as it could, Measured the pressure between turbo and intercooler and get max 1 - 1.1kg with full throttle in 3rd.
Questions I have:
- is ID of 2,5 inch enough for a TD5?
- what about modifying the internal of the airbox?
- increase the pressure of the VNT?
