I just recently got a 98 reg cab dually 4wd with a few mods and was wondering if anyone could give a guess on what kind of hp I'm around, wanting to know about where I'm at on power before I start adding and if I need to change anything, please feel free to give suggestions or a estimate on what the truck should be making hp wise. List of mods below:

66mm turbo, 5x16 injectors, Valair dual disc clutch, head studs, Hamilton valve springs and push rods, 4k gov springs, cut delivery valves, fass 150, aftermarket intercooler and electric fan. Kdp has been fixed. Traction bars, shaft loop, pillar 3 gauge pod.
#5 fuel plate .024 dvs

 

Dude, there's no way to tell. The engine could be as tight as a Quaker boy or tired as a one-legged man in an *** kicking contest. Some of what you listed doesn't add any power to the engine at all. Efficiency, maybe, but that doesn't always equal HP numbers. What does your *** dyno tell you? Maybe MysteryNC can chime in. He does that kind of sh** all day long.

If it were my truck, the very next thing I'd do would be to put a 4" or bigger exhaust on it, especially fueled up the way it is.

And welcome.

 

Oh yes I forgot that 4" exhaust with 7" stack, and yes I know it's hard to tell just wondering how these would act on a stock motor just so I know my platform. But I understand ya, and thank you

 

Seemed odd to me that it has all those mods and a stock exhaust. I wish I was good enough to tell you what you want to know, bud. Without knowing how it's tuned, what elevation you live and what kind of condition it's in, I'm not much good to you.

 

That's fully understand able, I'm new to 12v so don't know a whole lot about em, just wanna make some changes truck has plenty of power just wanna add, wanna get around 500 still driveable and ill be thrilled ha, thanks for the input any way though.

 

buddy of mine is close in mods to what your running, he dyno'd out at 458 hp to the ground. throw it on the rack to see, its worth the little $$ it costs to make a run

 

Ill be dynoing it here soon be sure to drop back on and give an update, thanks for the input
