What to do to my truck?

stingmang · 07-18-2008, 12:28 AM

I just had a Fass pump installed and Dynoed. 325rwhp/2200lbs of torque. At least that is I what the print out said. I was dissappointed with the current mods I have done. So I may do propane or turbo next. I am not sure because I also want to do a solid axle swap or put a different lift on my truck. I just want a stout truck that I can use to tow, smoke the guy next to me, and not be afraid to go outdoors with. Is there such a formula? I am addicted, and my wife is going to kill me! I don't know if I'll actually reach my goal. I don't know anyone local that has what I am looking for in a truck to compare it too. One thing for sure I have to do something about my suspension. I am wearing my tires out, and I only have 12k miles on them. Any suggestions?

Well, I think something is off on the Dyno, because 325/2200 does not add up. Now 325/650 would make more sense, but you should be making more than 325hp.

Now, your signature confuses me. Did you swap out the rear end for a Dynatrac Dana 80?? And with 37's you should have been at 4.56 gears. We are doing a set of gears right now, 4.56 for 37's puts you right back at the stock ratio.

What all came with the Stg II transmission? Was it the kit or assembly?

the duramax is a bear to dyno so don't feel bad with those numbers because in my book dyno numbers don't win races or truck pulls.when i dynoed the dually the best numbers i could get were 450hp but it was eating 500+hp trucks at the truck pulls.

Maybe he's got the rear end confused with the Eaton G80? I dont know. But I agree, 325hp seems awfully low. Did you have the PPE on the highest setting? Did you also give the tranny a couple hundred miles to re-learn the new setting? (not sure if its necessary with ATS tranny still?) 2200ft-lbs of torque? That one is off for sure!!

You got all the right mods to make some good numbers, but I've heard before like tyreboyz said that its a beeatch to dyno a dmax. So don't feel bad.

Well my truck was Dynoed on a Mustang. Those torque numbers are not accurate. I am still waiting for a more accurate number. Yes my rear end is a Dyntrac 80. My tuner is on level 6. Suppose to be a 300hp tune. Ats billet trans complete with a copilot. Was told by ATS its good up to 750hp.

i would add a fuel system, and that will help keep you from working cp3 to hard, then maybe see about stacking a ts mp8, its a fuel pessure box.

the lift pumps would realy help with fuel delivery and in all reality you probaliy have in the 480-500HP/950-980TQR range at the moment.

I thought my Fass pump would be the lift pump. Is it not doing the same thing you guys are suggesting?

Fass is the lift pump. I would do another dyno session. your 37's will eat some power, but i would think you should be at least 400hp.
