Ditching my Compounds to go with Big Single. Help with Best S475 Setup. 6.7Cummins

[Jade67]

Like the title says I am looking to dump my compound twin setup (DPS 62/S475) in favor of a Big Single S475 or possibly a S480. I have been having issues with the Compound setup due to Drive Pressures being high and I am to the point that either I start the twins over or just go with a big single.

Truck will rarely see any pulling. Most of the time it is Daily Drive at 80% Highway but I still want something that I can play with on the weekends or at meets.

Let give you a break down of what I know the truck has done it right now:

'07 5.9 was swapped out for a 6.7
-Balance/Polished Rotating Assembly
-Cam, Spring kit, valves, pushrods all upgraded
-Getting ARP 625's installed with new turbo setup but currently has ARP 425's
-Industrial Injection Race3 180hp/45lpm Injectors
-Industrial Injection Dual CP3s
-Built 48RE trans (Upgraded Valve Body, 6 disc clutch backs,Billet TQ, Billet Input shaft and drum, trans cooler, etc)
-Hellman Fuel Sump
-CNG Conversion

I am sure that I am forgetting something in there but that is the basic breakdown.

I am looking for the best S475 or S480 setup that is going to result in good power output while still being able to drive it. I have heard a lot of good about the S475 as long as the fuel is there which I have covered.

I am looking for EVERYTHING... Turbo, Exh Manifold, wastegate or BOV if needed, etc...

I would love to be sitting at 850+hp.

dps 62/75 bit small for 6.7 from my experience. A big single i really like the sx430 series in 78mm work really nice ,

The 62 was definitely on the small side of things that is for sure. I was debating going 66/s475 or 66/s480 but I think that I am just going to go with the big single

s475/87/1.10 would be pretty sweet
