    LMAO!!!!!!!!

    LOLOLOLOLOLOL

    Ahhhhhh hahahahahahahaha!!

    Phase one I just tested stage 1 and 3 so I could tell everything was turning on and off correctly. That test was:

    Stage 1: 75 HP
    Stage 2: 0 HP
    Stage 3: 75 HP

    For all you who didn't like my first test, I'd like to announce testing phase two:

    1st stage: 75 HP
    2nd stage: 125 HP
    3rd stage: 200 HP


    Can NOT get the grin off my face!!!!


    Bwaaaaa ahahahahahahahaha

    1) yes - it worked perfectly
    2) The engine is going to hold up nicely
    3) The transmission won't

    I'm ready for the drag strip!!!!

    ....I'm confused, so it's goin to be a 400 shot by the time you hit the 1/8th mile?

    No - those are the total HP shots, and the total shot is triggered in 3 different RPM ranges.

    For racing, I'll start with 100HP, bump it to 175HP, then bump it again to 275HP.

    what will be the advantages of your stages compared to my 200 shot all at once

    Drive train shock. It should come in a bit softer and adding the large chunks on the top of the rpm band "should" keep from blowing the heads off the car.

    In theory. Time will tell. I just keep thinking about that .10 inch top ring land. Scary.

    So that should be right at or just above what the transmission is good for right? I might hold together for a good while?

    Well that's complicated also, the PCM will pull timing to keep the input torque below the 580 newton meter input transmission torque rating.
    It still hasn't been answered what effects Nitrous has on engine PCM parameter operation.
    (I know you just love these bits of PCM logic statements :shifty:)

    That's the theory - but it isn't true. I've already dyno'd at 630 foot pounds at the rear wheels.

    But that's part of the reason for the triple stage solution. I maximize area under the curve, while at the same time actually lowering peak torque. The peak force this year on the triple stage system will actually be lower than last year's 175 HP single stage system. However, my peak horspower should go up 75-100 HP (from 510 HP last year - rear wheel)

    Yea, I was just going on what the SRT engineers said in a chat a long time ago. Something like the transmission has been around forever, is rock solid, and should be good for 600 to 700 hp. So if you think optimistically:good: no idea about torque

    No doubt your doing real well, I know right now on a couple Jeeps we are seeing some major retard timing issues when the inut torque approaches maximum input readings. But yes if you can make up for it in other ways it's all good.

    Also as an addendum, I keep forgettting the LX cars from the start have the ability to turn off ESP/ABS totally. The Jeeps don't have that option.:sad:

    Ahhh yes. It's pretty easy on this website to forget we're talking about two slightly different drivetrains without knowing it. My dyno results came after the Diablosport Predator. I'm wondering what you Jeep guys would see? Still can't turn it all off?

    Maybe I am wrong here Jeff, but doesnt pulling the ABS and ediff fuses totally eliminate ESP/ABS and make the jeep 2wd?
