I've got a 2002 2500 with mach 4's, tst comp, smarty, edge ez, firerings and headstuds, fass pump, 4in turbo back, phat shaft 62, and a 3250 south bend clutch. I dynoed 522 with 1300 ftlbs and im thinking about finally building a twin setup for it but im not too sure what kind of turbo i should use for my big charger. Ive heard a full size b2 would work good and use my 62 for the small charger but what i dont know is how big a full size b2 really is. any guidance from you guys would be greatly appreciated i would love to have a setup that would have me around the low 700's but would still be able to drive it every day and pull my boat. any ideas?

 

Welcome to DTR!

700 hp on a VP-44 CTD is not easy. Won't get there on Mach 4's..... and requires NOS, unless you really want to invest some serious money.
522 hp on a 62 turbo must get a little hot when running hard?

For twin set up, I prefer an S400. B-2, while technically an s400, is older technology.
I would talk to RIP at Source Automotive.
He has a kit to add on to your PS62. Nice set up and most reasonably priced way to go, IMO.

I was thinkin about goin with maybe mach 6 or 7's once I started the twin setup. it really doesnt get too terribly hot but i can get my egt's up to 1500 if i really wanted to. I am pretty much wanting to build an entire setup that will produce low 700's im aware the injectors i have now will not get me there.

 

Twins are great... Hardly ever get over 1200*, unless at the track.
FYI - With Summer coming, I will be switching back to Mach 4's.
6's are driveable, with twins, but any load in the back and it's hard not to pour out smoke with throttle changes.
Once we hit 6 months of 90*+ every day, it requires careful throttle management.
It IS more dificult to control smoke with an automatic ... and you may not get as hot as I have to deal with.... so you should be OK.
Just sharing my experience.
I daily drive with just the Smarty and 6's..... about 425 hp. Adrenaline in reserve!
