I finally got some #s on the new build no spray= 462 hp
745 lbs tq

N2O = 588
870
I have the dyno sheet but I don't know how to post it. these # are good but I expected a little more with the drugs. can someone tell me how to get a sheet of paper scanned onto the computer and then post it here.

Not bad numbers at all, nice job. Is there any smoke left when you hit the juice or is the exhaust clean? If its completely clean you might be over spraying and need to jet down a touch. I was running right at 100rwhp shot with a .078 jet, so with 2 stages you should be able to spray more than the 120rwhp that your doing. What size are your injectosr?

the injectors are "530"s with a .008 nozzles and no there is very little smoke. you think I need to come down in jet size? with the setup that I'm running should I still have the coal cloud?

what jet sizes are you running? 250's should be good for over 600. Also what kind of dyno was this done on, your tq numbers are way low for your hp numbers.

I'm not sure of the jet size my cousin did all of that install I'll have to see or ask him. the dyno was a Mustang something .

thats what I intend on doing, I sure as crap am having a time with this N2O thing. the stacker system that I used to run was straight foward but this digital dual stage thing is differant. I called, the jet size is he said a 250 something. I noticed this evening that I'm building about 33# of boost at wot without juice if that helps. I'm not sure what kind of boost # I should be seeing. the only tq # that I think is low is the drugged up #s the natural #s are about in line I think

33 psi sounds way low for your mods, check for boost leaks and up pipe leaks on the back of the engine (lots of soot). Sounds like your using the gasser rating for jet size, that doesnt work on diesels. You need to know the ID of the jet. Who is CCM? a cam grind could really throw things out of whack too.

I'll check the jet sizes tommorrow and see what they are and CCM is Central Carolina Machineing they're in mocksville NC. I thought the boost # were low I was seeing almost that before the build. I just finished with this motor and it has some bugs to work out. Robert at CCM told me that this particular cam grind is what he has in his truck and the builds are about the same in his engine and mine, this is how I thought my # were a little off his # are much better.I had my cousin that works for CAT do most of the build just because he knows more about this stuff than I do, I build houses he builds engines

. anyway I'll be back tommorrow with more info, thanks Luke...
