I too have also considered fitting the TTE supercharger next year to my car, would like to know the best place to buy, you mention PROLEX but looking around the site TDI look cheaper (any difference).
will it make the car more difficult to insure (limit the number of people who will insure me).
does it also affect reliability of the car, have noticed Gord has a problem with his car (sorry to hear) and heard of other members taking the supercharger back off the car.
