    I was watching an episode of Ignition where they put the Hellcat vs the ZL1 Camaro head to head and the Hellcat made 671.64hp and 606 lbft of torque. I have seen some numbers of guys on the forum and I don't think anyone has got close to those numbers. Seems to be a big difference from Hellcat to Hellcat. Maybe Dodge gave them a " tweaked" Hellcat?

    For the guys on here that have put there stock car on the dyno please post your numbers so we can get an average. Also is anyone getting near 670???

    I think there may be another thread with this info possibly?? My baseline pulls proved 672.5 rwhp and somewhere just over 600 torque. Cant remember the torque # exactly.

    Dyno is a tool, numbers vary, track is the place after your numbers

    Search dyno numbers lots of threads. Anywhere from 620-640 is normal but way too many variables on a dyno.

    I ran 10.8 at 126 that's the only number I care about.

    I understand what you guys are saying but if there's 30-40 even 50 hp difference at the rear wheels from car to car that matters. Yes 1/4 mile numbers don't lie but maybe the 1/4 mile times might be a little more consistent if the hp was consistent. Not to mention there's something wrong if one car is dynoing 50 more hp to the rear wheels than same car.

    You go to the strip with a car that dyno's 620rwhp go against the same car making 670rwhp same tires same launch you will care. Thats a big difference to me hopefully mine will be closer to 670;)

    I just want to get as many stock dyno numbers as I can to find an average.

    Good as she gets, the D/A was basically zero.

    Perhaps FCA would publish production tolerances and output. + or - 10% would not seem out of line, as long as they make at least 707 at the crank.....

    That's a good DA.. cold motor Meaning low antifreeze Temps, coolest possible intercooler. Descent octane in the tank.

    Remember FCA dyno ed each HC engine before leaving plant in Mexico.
