Still searching for a Supercharger for a 4.8is
 

Anyone have any luck locating performance products including a supercharger for the 4.8is??? Its unbelievable that there are no parts for BMW's fastest X5. :dunno: :confused: :tsk:

I feel the same way. Outside of powerchips, I've had no luck finding anything. :tsk:

There really doesnt seem to be much for any of the valvetronic V8 X5s, except from Kelleners which has supercharger kits for both 4.4i (2004+) and 4.8is. Not sure why it's taking so long for other tuners to do something with these engines.

Maybe because most people want to keep their warranty. :) Thus no urgent desire for aftermarket mods on new vehicles. :( Also takes time and testing to prove claims of improvement.

Usually supercharger kits come with a supplemental warranty. But it doesnt matter, because there are plenty of people that would do it anyway if it was available. I know I would.

It seems Kelleners pulled the 4.8 supercharger off the market. I checked a couple of days ago and they do not list a charger for the 4.8 any longer.

I just emailed a guy I know who is a vortech specialist to find out what options there are. He is aware of smaller shops doing custom SC's for many applications and may know something about fitting a 4.8is and doing the critical chip programming. I will let you know what he says soon as I hear back from him.

It is still listed on their website, but I did not contact them to see if they still sell it.
