supercharged cummins?

[KParsons]

i took my super charger off my 94 ford 351. it was a 5-7 psi low performance unit. when my 06 cummins goes off warr. . is there a way to make this work, with out going crazy?this was a belt drive bolt on. if not i will sell it. thanks for any input. kp

I think piers did one for kicks.

yeah, something like 10psi at idle. but it didn't flow well on the top end.



If I recall correctly, if you can get a setup working on the Detroit 2 stokes have with the blower and then a wategate/bypass to open and move around around the blower once the turbo gets moving there would be little to nothing that could keep up with that setup.

My bad, 8psi at idle

that is kind of odd. Superchargers usually don't produce any boost @ idle only off idle and under load. unless you OVERDRIVE THE LIVING He!! out of it and even then it is minimal.

 

[CBrahs]

It would be cool if you could fab something up to where the supercharger would provide low boost to about 20psi and then a turbo taking over after that. You would have NO lag but would need a 6-71 or larger screw to get that kind of boost. Superchargers rob a ton of HP but make up for it with the boost. A healthy small block chevy could not turn a 14-71 that is on a top fuel car, they take that kind of power.

Sell it. Turbos are much more efficient.



If you want high tech, make yourself one of these:

a little overly complicated eh...

I like that idea. I'm sure it eliminates the need for a DMF.

Turbocompounding is good for another one point or so thermal efficiency which is a huge deal for a marine diesel powering a supertanker or mega-container ship.

Got to find a way to turn the supercharger so that it's not robbing so much HP. But you can't just go with a small supercharger, because we need to move ALOT of air.

 

[KParsons]

small pully?

well you guys gave me some interesting idea s . this is like the paxton supercharger. if i needed more air, just put a smaller pully? it runs off the crank, like a early fisher plow set up. well its a little crazy any way!! kp

if i remember right i belive holset has been playing w/ this idea on some medium duty trucks at least the have a model i dont know where they are in it now but they say it works rather well so who knows.





on edit i see the pic from higher up on the page didnt come through that comment was supposed to go w/ the turbo gear drive setup shown above

 

[ThrottleJockey]

Use a Lysholm screwcharger (Whipple).



90% efficient with NO intercooler! Use it in conjuction with a large, 'primary' turbocharger. Route the plumbing like a 'twins' set up. Air Filter, turbo, intercooler, whipplecharger, intake. Use a device like an exhaust brake valve on the intake plumbing to bypass the whipple at mid range and top end.



And hang on to something.



Google 'Volvo Penta Marine Diesel'.

Yes, it has been done... . Piers and Nascar Mark did it a while ago on a 2nd gen. I wish a kit for this would come out!!! It's different and supposedly has unreal throttle response Oo. Oo. Oo.
