I don't know what your running for fuel but if your wanting more power I would do some e85 or meth and up the timing if your not already. You can also pulley down and do a overdrive crank pulley to really make that d1 come alive .

 

Running dual walbro 400 pumps. But the closest e85 station is 15 miles away.

 

If I'm currently running 12 psi, how much of an increase will I see if I pulley to 13-14 psi? I'm running about a 70% meth/water with a 12.4 gph nozzle

 

14 psi on the 6.0 should be in the neighborhood of 700 rwhp. Do it

 

That would be interesting. Lol

 

As long as your running one of two thats good.I doubt your even cracking 600rwhp I would bet your closer to the 550+ range with 110 mph trap speed. You just need to pulley down and run some boost ! What you waiting for!??! Get your self a 10% overdrive crank pulley and get a 3.5 pulley on the head unit. What kind of BOV are you running?Seems llike you should be hitting around 14 psi with a 3.6 on that thing. What are you shifting at ? Have you done a leak test on your intercooler tubing?

 

I know this is just a calculation but they seem to be pretty accurate. But this is at 600hp, 5400lbs, 3 shifts, 32.6" tires and 4.56 gears

its right along with all of my times.
that was peaking at 12 psi in Tucson. My one short WOT run that I did here in Minot ended at 6700 rpm and 12.8 psi. still had 200 rpm to go. So Im looking for a 3.5 or a 3.4" pulley. I kinda dont want to get a different crank since this one is already keyed.

 

I also had 5 gal of e85, and 10 gal of 91 and spraying 100% meth when I ran that 12.02

 

I think that calculator is a bit off, eventhough in Tucson I could only trap 96-96 n/a, but the effect shouldn't be as bad on a boosted motor. Looking at some online calculators, I'm coming up with around 515 rwhp. Seems a little low for a 6.0 on 12 psi. Although you are AWD thru an 80e...

 

well my goal is low 7s in the 8th. I ran a 7.6@91 before. a low 7 should be good for a mid 11 in the 1/4. I think I would be happy with that.
