Re: st50 turbo

Definitely will need a lot of customized parts. But it should be possible. What kind of air flow does it pump out? The stock ones are about 600 cu.ft./min (that is the sweet spot, although they can run up to about 800, but that is not optimal; gets too hot, etc.).

The turbo you are talking about would only be useful for all out racing, because it is f-in huge:

That is one bad a$$ unit, but for the street, it would take 30 minutes to spool! Possibly (and I don't even know if this would work), you could power brake it for a track racer.

Bigger is not always better. Check out Tadd's work with the Aurora 5000, which is a lot smaller than the one you are looking at and it spools like crap. Yeah, he makes 600RWHP, but he ain't happy with the spool time. For a big turbo like that to work, you need something (like a small turbo) to feed it. Otherwise, it would seem impracticle to me.

Also, where are you going to mount it? In the bed? It's so large, I think you would need a hood with a foot of ADDITIONAL clearance to fit it in th engine compartment.

Re: st50 turbo

I don't know, but look at that sucker. I has to have 4 times the flow area our stock turbo has. I'll guess 2500 CFM. It's a monster, and my concern is still there about having enough exhaust to feed it. I tried the Cummins site and it is not in their general list of turbos. But this may be another company's name for it (like a friggin Mack truck or whatever it came off of), so ST50 may not be findable on Cummins' site. Suffice it to say that it won't be easy to make it work. But it probably would be possible, but i think you would need twins.
