About a month ago i read a article in diesel power that talked about a supercharged duramax. Has anyone done this on their truck, they claim a 300 degree drop in egts, added 3.5mpg and alsmost or no turbo lag. An info would be nice, the article was short but seems like an awesome setup. Thanks.

Go to the tread called, Roots charger with twins. Ck it out and then check out all of Micky's posts you will finds tons of info.

Dunno about the temps and mpg, but the reduction/erradication of lag would be accurate (positive displacement).

i read that too, sounds like it makes sense.

Empire diesel and Pro charger are working together to make kits for the public for Chevy, Ford and Dodge diesels. They have clips on youtube.

Yeah here is acouple thread about Empires setup.
