    Hi Fellow Enthusiasts,

    Today I finally was able to dyno the car for the Hellcat I bought in May. Best run was the first of three, 673.9 HP, 611.44 Torque. (see graph for all three runs, each run was worse than the previous I'm guessing due to heat) Only mod is a K&N cold air intake & filter I bought online.

    So, would like to know what a completely stock hellcat pulls on the dyno so I can see if the K&N is helping or hurting me. I never dyno'd it with the stock intake/filter and it was a pain to remove, so I'd rather not try to put it back in for a true stock baseline run. K&N claims almost a 38 HP increase, but I've heard they don't really do anything and can actually hurt power versus the stock air intake.

    Is the HP about what you would expect to see? What's the percentage increase to estimate the HP at the crank?

    Thanks!

    I've been watching for about a year and I'd say yours is about 2 hp higher than what the highest stock cat is delivering. I've seen 660s and a 671 . Don't recall seeing higher than that. I'm sure lots of people will chime in

    Loss at rear wheels is an estimate at Best But usually around 15%. Puts your cat at a ridiculous number out of the box if 15 percent is true

    These cars lose 10-12% tops. 673 computes to 790hp with 15% loss. No way

    So 10% would put me at about 770 it would seem.

    Yea dynos are crazy. Lots of variables. The same car may do 640 on a different day. Seen it many times. That's why I take dyno #s with a grain of salt

    Great numbers one of the higher ones I've seen. Guessing you have m6? Just remember dyno really tuning tool. Sounds about right for m6 hellcat.

    740s sounds reasonable as I think the Hellcat is a bit under rated. I think during initial testing they were 725ish? 15% I agree is a bit much. Newer technology parts arent going to lose the same HP as the older stuff.

    Now back out around 30hp for the K&N and it seems pretty much spot on.
