As the title indicates, I'm curious about the prospects of a supercharger for the 5th generation 3 series cars. As far as I can tell nobody currently sells one. Anybody in the know as far as future products from Dinan et al?
i assume you mean a supercharger for the naturally aspirated 325/330/328? Or are you talking about replacing the turbos in the 335? Dinan already has a ECU flash for the 335, but i don't think it has any plans for what you're looking for.
Yes, I am talking about the normally-aspirated engines such as the 328. Many of the previous generations of BMW straight sixes can be fitted with aftermarket supercharges but there does not yet seem to be anything like that out there for my E91.
