Im getting back on a dyno in a couple days and want some peoples guess on my hp. last time I dynoed I almost cried, I went there thinking I was going to dyno high and I ended up low and was very disappointed in the truck (552hp). Sense then I have changed a couple things and added a couple more things, tuned it a little better and just gave it some TLC. So I want to know what I should be expecting on the dyno. I would love 700, am almost for sure im above 600. So anyways this is what I have. Ats exhaust manifold, afe stg 2 air intake, 66 silver bullet, external gate, ats intake manifold, fass 200 gph(45psi), 5 inch exhaust, modded cp3, 180hp injectors, studs, valve springs, smarty tnt/r, suncoast fully built tranny. anyways i want to find out if i think im going in with to high of hopes again or if i should be thinking the number i am. i also have a 2 stg nitrous set up installed that i will be trying out one with .042 jet and the other with a .078 jet. So what do you guess think I should expect on #2 and with spray?

 

You should def be there, had a guy here this past weekend put down 636 with a 64 instead of a 66, and no NOS. Pretty much the same setup tho.....minus the springs

 

Who was that?

Yeah, I see some big numbers. If you are driving on the dyno, hold the brake a little and build some boost before he loads the dyno, it will help those numbers a little...

 

ya i will be happy with 700 or close to it. i would love to be over the 700 mark but i just dont want to get my hopes up again. lol when i dynoed that 550 i wanted to put the truck up for sale that night. o ya i dont know if it makes a difference but i also took the 35 inch tires off and have stockers back on.

 

Yes smaller tires do help. Not enormously, but they do help.....PS, MADHAT, made 636 hp with 35s

 

Who's CP3

What kind of Dyno?

And finally, it'll depend on how well you can get that 66 spooled.


Dynojet 248, and a good CP3, with good boost numbers, I'd guess 670+

 

the 550 was with these.35 inch tires, 66 silver bullet, ats exhuats manifold, afe stg 2, ats intake manifold, studs, 180 hp injectors, modded cp3 (less modded then what it is now), fass 150 gph (12psi), suncoast tranny, bullydog pedifile larry, mp8, stock exhaust. i dynoed 520 with the mp8 on and 550 with it off. this time when i dyno ive also done a couple other mods that im testing out that i didnt list. so it would be cool if i hit 700 or more.

 

dyno jet.

the 66 spools fine, last time i dynoed on the dyno jet with out holding the brake i hit 60 psi of boost within 5 seconds, then the wastegate brang it back down to 45psi.

cp3 is Darkside diesels stg 3 cp3 with a couple secret added mods done to it.

 

you're definitely on the right track. I'd say you're in store for some good numbers.

 

And would have made 670 on the pizza cutters.....but Noooooooo......
