Their are a few supercharged + turbo'd cummins's kicking around on the boards here.

Also, it isnt anything new, like stated above, detroit has used superchargers and turbos on their screamin demons since the ice ages

Don't forget they used both on WWI and WWII fighters and bombers.

And they even had water/meth injection too!

Who would that be?

Your search button works as good as mine. I dont recall any names but these things do come out of the woodwork every couple months.

 

[ykdave]

nope, but this topic comes up a few times a month and quite a few different setups have been posted.

Yes, its really not a HUGE hurdle to overcome. You just need the material and tooling handy to build an adapter to go between the blower and the head. or better yet (im sure alot of them are this way), shave the stock intake off and build a new one that the blower can bolt onto directly. and you also get the bonus of being able to port the head after the intake is shaved off.

The only thing I didn't fully understand was the use of what some were calling a "jackshaft". Seemed like a O.D. for the supercharger?

Likely because they are usually seen on gasser engines spinning at higher speeds 6-7000rpm vs a few thousand less on the ol cummins.

I imagine they probably have to spin the hell out of it so it doesnt become a restriction at higher rpms also.

Hmmm, i would assume by that ammount of boost the supercharger is just freewheeling and the turbos are making the boost.

Hard to say, i can see that woking on the above style supercharger, but their are other guys running roots style blowers too, which technically you cant push air through them unless the seals are f'd...

 

[ykdave]

trying to remember off the top of my head but IIRC one of the trucks posted before with a roots style blower was putting down something like 600lbft+ @ 1200rpm
