    They had a large fan running, but I felt it was too low to the ground to have a large effect on the intercooler. I felt the airflow from such a low direction would be blocked a good bit by the winch and winch cover. They also stated that the relatively humid and warm weather didn't help me out.

    The shop called their dyno "the heartbreaker" because they feel it is extremely accurate/conservative compared to other local shops and it was calibrated within the last 3 months.

    Sounds like we might need a local owner of a stock Wrangler to volunteer to create a stock baseline dyno run at that same shop for a valid comparison.

    I have 3 stock dyno runs. All at different times of year, different jeeps. different dynos.

    The lines are all very close.

    I've never done a dyno on any mod where the manufacturer didn't think it should have made more power.

    Also the number i posted was SAE. Uncorrected would be higher.

    If you are confident in the validity of the results, then let's see some stock vs RIPP vs Magnuson vs Prodigy charts!

    I have the chart prepped, Im just trying to put a JL logo on it, so I dont want to kill myself when I see it pop up elsewhere.

    Ill have it up tomorrow.

    This should be the story. Keep in mind all the results should be on the same dyno same configuration, same correction factor etc...
    My thoughts are as follows.

    1. Magnuson by design will deliver the highest off idle TQ gain
    2. Magnuson will also have the lowest overall performance gain
    3. Magnuson power will decline the longer it is ran due to heat soak and highest IAT

    4. Ripp by design will have a linear power curve and will make peak HP only at max RPM
    5. Ripp will make good power as the supercharger is large enough to move a high volume of air

    7. Prodigy by design will deliver more power than ANY forced induction system on the market
    8. Prodigy will make crazy power in the midrange where the Wrangler needs it the most Contrary to most dialogue
    9. Prodigy will deliver sea level performance at higher elevation due to the use of a wastegate
    10. Prodigy system can be upgraded giving it a win for HP per dollar

    Stage 1 is shipped with Red spring .4 bar
    Stage 2 is White .5 bar

    Read the bottom right of the image. I personally prefer the White and Green combination for Maximum fun.

    Looks like the spring that went into my wastegate may be the far left "grey" or MVR-Plain. It could be the black and a figment of the camera's color settings.

    Wes, why does your dyno chart show a loss of power, I understand the goal of midrange power, but I cannot understand why the prodigy power line dips under the stock line.

    Also, can you give your position on axle gearing with dynos?

    What tranny gear was prodigy's dyno done in?
