Not really "news", but I just saw Hellcat dyno numbers for the first time...
The "707hp" Hellcat put down 670rwhp and 605rwtq in the Motor Trend test vs a ZL1.
For reference, the ~740hp Ferrari F12 Berlinetta puts down 585rwhp on a Dynojet. So basically, you have a car that's close to 800hp for $65k with a warranty and an 8-spd auto. Like the car or not, you have to admit, that's a lot of bang for your buck. |
yup an awful lot of bang .

It's probably more like 750hp at the crank. Point being it's underrated. Probably should have thought about it a little longer before I posted it. |

The Hellcat is in the Muscle Car catagory; the others are in a different catagory. |

Isn't there some regulation that states an engine must be within XX% of claimed power? |
It's my understanding that each Hellcat engine is dyno'ed before it is installed in the car. So that 707 HP would be at the crank.

When you get over 400-500 hp, you can't just say the car loses 15%. Rule of thumb is out the window. If a drivetrain takes 70hp to spin at 7000 rpm with a given set of gear ratios, then it's +70 hp at that rotational speed to get pretty close to crank hp.
The parasitic loss of a roots blower is a wildcard, but assuming it wasn't running hot yet... as an example- a C4 corvette typically takes 65hp to overcome the drivetrain- maybe a little more if you are spinning to 7000 rpm. |

...and outside of internet dickswinging, talking about peak dyno numbers is absolutely pointless. How much power does it make? A shitload. Want to know what that gets you? Take it to the track and find out. Out of curiosity, I pulled up the article. Some parts are rather amusing... Quote:
You want to know why it shouldn't be compared to a Corvette? Because even a Camaro makes it feel like a boat. I the Hellcats. I'm not knocking them. While I have no use for a 2 door Challenger, I may consider a Charger when they come out. With that said, call a spade a spade. They aren't some amazing sports car ready to take on the exotics. They are a straight line warrior. Nothing more, nothing less. |

as mentioned earlier, automatics loss is not a set amount either. WOT runs - the TC is not locked. The more load added (comparing first gear to second gear - for example) the higher the loss. Quote:

the rule-of-thumb :) for muscle cars is that they are 2 door versions. Todays Charger is 4 door; which would typically lable it as a "sedan". What are fast & powerful sedans called? :confused: and then, this: http://fc06.deviantart.net/fs71/f/20...r_Mad_Mike.jpg |

Talking about how much power something makes isn't pointless. It's interesting. That's why we have forums. |
