Default Under Drive Pulley Kit

Anyone know of a company tha makes a pulley kit for the m42 ti? Does anyone have a kit or has a custom kit? Would it be worth getting a custom kit?

That would interest me as well. I would also like to know if it can be done when the car has had a DASC installed. There is a company called Unorthodox Racing , Inc in Deer Park NY tel 631.586.9525 Fax 631.586.2599. Advertising 3-series/M-Series/Z-series pulleys. Perhaps they could do custom as well.

UDPs on supercharged cars would slow down the rotational rate of the supercharger and produce less boost. These two products from my knowledge normally don't go together.

You could put udps on only the other accessories - water pump, p/s pump, alternator, and not affect the rpm of the blower. Only if you change the size of the blower pulley or crank pulley will it affect your boost.

I love that video! It seems like you got a horrible launch though.

Hahahah, yeah, I was concentrating on launching it well. It's so easy to wheel spin the car.

I think ClubSport has it from my understanding. Now, does anyone know of a supplier, or do we have to order custom? Also,
would apropriate 6cyl pully for Bosh or Valeo alternator, depending on which one you have, work or are alternator pullys that different?
