    • Another stock Dodge Challenger Hellcat baseline Dynojet dyno - 662 wheel horsepower

      We have a pretty good idea of Challenger performance and power. More baseline dynos for context certainly do not hurt and yes the Hellcat 6.2 liter twin screw supercharged V8 is underrated. How does 662 horsepower and 618 lb-ft of torque to the wheels completely stock sound?


      The power curve is actually very nice. Horsepower just keeps climbing throughout the entire rev range is a fairly linear fashion. There is just gobs of torque everywhere and the torque curve does not fall off a cliff.

      SeriousHP in Houston plans to tune this car on E85 and we have already seen some of their E85 results. We will see how far they take this car but on ethanol with more boost we should see some massive bolt on numbers.

      Oh, and the Hellcat is putting out over 100 wheel horsepower more than the Viper. Maybe time for that car to get some boost as well?

        Arrow Racing Engines and The Viper Exchange are already on it.

        That's right. They're the ones doing the twin screw blower and a heads/cam package. You're on top of things.

        And now thanks to Arrow Racing selling their PCM forced induction will be possible for other tuners, as well as what you previously mentioned, heads and cam, etc. (They won't have to shell out for more expensive systems such as Pro EFI)

        You must have been researching the Viper.

        The ProEFI is also an option though. There's a guy who put a custom turbo setup together and was making well past 1000 whp on the stock internals.

        I'm pretty much sold.

        I've been known to have far too much free time.

        Yeah that setup is pretty insane, honestly though I just want to see someone make a "cheap" kit with a massive centrifugal supercharger and sub 10,000 price tag. The supercar tax on FI for these cars is obscene. What head unit do you think would provide enough CFM for such a huge engine?

        To hell with that on a $90k+ car.

        I'd go with the Procharger F1-X.

        That said, there is a guy that did his own turbo kit. Everyone else wants $45k+. If you do it yourself I bet you can do the turbo kit for the same price that you're talking about a centrifugal based kits and the turbos will blow it away.
