    For those thinking that getting your hellcat into the 9's is easy, I did some numbers for you, they may not be exact but should be fairly close. Horse power is taken from the engine not rear wheels and drag radials or slicks are used for tires. Loosing weight will be an issue as the faster you go you will need safety equipment to match the speed.

    HP 707 4400 lbs ET 10.71 @ 126
    HP 757 4400lbs ET 10.47 @ 128
    HP 807 4400lbs ET 10.25 @ 131
    HP 857 4400lbs ET 10.05 @ 133
    HP 907 4400lbs ET 9.86 @ 136

    HP 707 4200lbs ET 10.55 @ 127
    HP 757 4200lbs ET 10.31 @130
    HP 807 4200lbs ET 10.09 @133

    HP 707 4000lbs ET 10.38 @129
    HP 757 4000lbs ET 10.15 @132
    HP 807 4000lbs ET 9.93 @135

    Continue the calculations while retaining stock weight please. I'm guessing it'll take 907hp to get into the 9's.

    Thanks TopCat... Could you post the math behind this if it's not too much trouble?

    The bigger question, how do we shed 200-400 pounds...that's a lot of weight, if dodge can't do it, how are we going to...

    I don't think I like the idea of driving around on a milk crate,, the reason I bought the hellcat is because it has a Nice radio, seats, and comfortable,, I would spend the money in upgrading the drivetrain to support the extra power..

    Getting weight out of a modern challenger is not that easy if you still want it safe and looking like a car,the Hellcat is a super street muscle car and should stay that way, I'm not sure how the local tracks are going to treat the Hellcat as far as a roll bar, but I may do it anyway, RPM is a great company for this mod if anyone is thinking of doing it.
    As far as weight loss, take the loose stuff out of the trunk, passenger seat maybe, 1/4 tank of 93 and 2gal of 109, no cheese burgers on race day,LOL

    I bet if you were to take the back seat out and the passenger seat out,I think you would see less the 100 pound difference...

    I just moved a set of front seats in the warehouse, I'm thinking around 50lbs ea and the rear seats are maybe 20-25 lbs, having two race Challengers I can tell you it's tough to loose weight because the faster you go the more you need to put back in with safety stuff.

    So it sounds like it would be easier to upgrade the drivetrain to handle more power, after they crack the ecm,, I would be happy with around 725 at the wheels and be safe, meaning not going to break anything

    There's actually a chart somewhere on another message board where someone pulled and weighed everything...stereo, carpet, trunk liner, lid, seats, headliner, etc. It was impressive, but you really will struggle to find those pounds. Ultra light wheels are a big deal, carbon fiber panels, etc.

    My goal for this car would be to consistently trap over 130mph while maintaining stock like drivability and reliability, which may be entirely possible with the appropriate mods.

    The rear subwoofer, rear seats, front seat, and lighter wheels/tires would account for a good loss in weight. On the flipside, it might gain you a tenth or two in the 1/4mi.
