I know this has been beat to death but Im wondering if this combo would be good for 600 hp:

Super B Special
Smarty TNT/R
DDP 90s
Fuel sys

 

if you have a 66mm turbo I would say yes. I bet the super B would get too hot

 

i bet a sps62/71/14 would work great with that set up. keep egts in check and not suffer all that lag with a bigger turbo.

 

That combo should work pretty good. The only thing I'd be worried about is the cp3 no being enough. Perhaps an arson (sp) kit would help.

By the way the super b special is a 64/71/14 and IMO a 62 at 600 RWHP will get way to hot.

 

90 HP DDP injectors are matched great with the stock fuel system.. I'm probably the only person this has happened to, but I added the dual CP3 kit and went .15 slower than with the stock single pump on one of my trucks. That was when I was running the 90's..

My 05 4x4 dually weighed in at 8,040 pounds with me in it. It ran a 13.04 at 103mph with an II PS 62-14, 90hp DDP injectors, Bully Dog Scary Larry, TS MP8, and a K&N filter. No lift pump or pump mod. I also pulled heavy on a normal basis from FL to KY and back. I believe the calculators say it was a little over 600hp.. Very nice and easy setup.. I had less than $1,800 in performance mods (other than trans), but I shop around and buy used when possible.
