WHY?
Turbo and supercharged diesel engine is the best of both worlds.
Supercharger eliminates ALL turbo lag. You have instant boost from idle to max rpm.

yea it spools wuicker but it maxes out quicker. a turbo can keep building boost. also, it is an unnecessary draw on the motor. im sure on that DMAX they are centrifugal chargers, which really are not the way to go. you can only make so much boost and it draws power from the motor. turbos make much more psi. and u get twins to eliminate lag. thats why a smaller one is first, so it can spool the bigger one and make a crap ton of boost. thats just my oppinion

Yeah, I guess the "gurus" of diesel performance are wrong.
This is what Harry and Piers did some time back.

Impractical only if the information about the actual facts are flawed. The Duramax in question has a centrifugal supercharger and a single GT4505 turbocharger. The supercharger is clutch actuated and disengaged over 15psi. This is a very practical solution for 600+hp in a daily driven application, the truck in question is daily driven @ 733hp. So I would bide my words if actual understanding of an idea escapes you.

I have never, ever heard of a clutch actuated supercharger, but if you could get one set -just- right it would be perfect!! kind of like mad maxes, flip switch that nobody can figure out how to disengage a supercharger....

I take the clutch actuation back, that was a conversation with Nathan from MPI. Micky's Duramax has an external gate in each header controlled by an Eboost gauge that commands the desired boost pressure from 1-60psi. The supercharger is 1.5-1.8psi @ idle and the inlet after the turbocharger is 3-3.5psi @ idle. The supercharger pulley is 41 tooth and set to run 24psi @ full load.

I would like to know some more info on the truck in the photo! That Whipple supercharger can easly make 25+ PSI boost almost instantly. I think it would be a great Idea

Here is what I am seeing, 3-5 people in this thread with sufficient blatent arrogance to judge a person without knowing the facts. I remember when I knew it all while running a stock turbocharger...

If its set up right I just dont see a down side. The whipple charger using the Lysholm twin screw desighn is one of the most efechint superchargers made. They only take 2-3 HP to turn them and produce a cooler air charge than any other supercharger out. & they have the ability to run 25-30 PSI almost instantly. What is the down side?

I'm not running a stock turbo... and I was simply making reference to Mad Max, I always dreamed of having that setup on my Camaro..
I don't have the time or the money to supercharge my 5.9, but I say it would be freaking sweet, however I had thought about a small blower on my drag car and a turbo to push it, partly for looks, partly for scare factor and all in the name of power!!!
