    • A look at the Magnuson Vengeance TVS2650 Dodge Hellcat 6.2 V8 supercharger upgrade/swap

      The Hellcat 6.2 liter V8 comes from the factory with a 2.4 liter twin screw supercharger with 11.6 psi of boost. It is very strong but for those wanting even more Magnuson offers a larger TVS2650 blower conversion for about $7k.


      Why ditch the twin screw for a roots TVS style blower? Well, here is Magnuson's argument:


      Their kit includes:

      • 6th Generation TVS2650 Supercharger retaining OE electronic bypass valve
      • Patented cast-aluminum high-velocity-port intake manifold
      • Liquid-to-Air Intercooler
      • Extruded aluminum high flow fuel rails
      • Front and rear fuel crossovers
      • Handheld Programmer
      • Large front-mounted heat exchanger
      • All necessary fittings, lines, belts, and hardware required

      They claim it is much more efficient of a supercharger:

      • True reliable operating range to 20,000 RPM
      • 33% higher flow than TVS2300
      • 10% higher flow than a 2.9 screw
      • 14% higher adiabatic efficiency at 14k rpm and 2.0 pressure ratio compared to screw 2.9 at the same flow
      • 75F lower discharge temperature at 14k rpm and 2.0 pressure ratio compared to screw 2.9 at the same flow
      • 26 HP less input power required at 14k rpm and 2.0 pressure ration compared to screw 2.9 at the same flow

      If the TVS2650 offers higher flow than even a 2.9 liter twin screw then the TVS2650 makes even more sense than the Demon's factory 2.7 liter twin screw blower for a swap.

      The question would be, at what point does the twin screw become more efficient than the TVS blower? A twin screw tends to show its advantage at higher boost levels. If spinning the blower faster and faster will the twin screw eventually win out?

      Magnuson recently tested their TVS2650 out on a Challenger Hellcat at the Famoso dragstrip in California. The weather is very hot yet the car was said to run a 9.9 elapsed time. Magnuson did not post the slip.

      It will be interesting to see how the TVS2650 roots stacks up to the Demon 2.7 liter twin screw. For those considering a larger blower, the TVS2650 certainly is worth a look. Hopefully more data will come.

      • TVS2650 Hybrid-roots supercharger
      • Installs in one day
      • 100% complete bolt-on system
      • No hood modifications are required
      • More power in a smaller package
      • 170deg. rotation of the supercharger provides a straight airflow path for maximum power and efficiency
      • Retaining OE Electronic Bypass Valve virtually eliminates parasitic loss (uses less than 1/3 of a horsepower at 60 mph).
      • Delivers a proven increase in real world "under the curve" power
      • High thermal efficiency
      • 2.4 pressure ratio capability
      • High helix four-lobe rotors with 170deg. of twist
      • Redesigned inlet and outlet ports
      • Improved air-handling characteristics
      • Acoustically designed for noise and vibration reductions
      • Utilizes all factory "push-lock" connectors

        Off topic but id like to see this charger on a C63. That would shake the scene right up.

        Exactly what I wanted to ask Magnuson about. Why aren't they using this charger on the M156?

        ROI, there is less of a tuning market than hellcats...in 2016 dodge sold 12K hellcats, that's where the money is...
        http://www.thedrive.com/muscle-cars/...les-are-rising

        In the 2007 (launch year) AMG only sold 1,353 (est.) E63 AMGs
        In the 2008 (launch year) AMG only sold 476 (est.) C63 AMGs

        https://www.6speedonline.com/forums/...model-usa.html

        Pretty surprisingly low numbers considering that's all of the USA, really goes to show how polarized southern california is, I see e63s and c63s all the time, new and old...

        The new TVS2650 is SUCH a good blower. It will be the only worthwhile blower upgrade for my V2 CTS-V (if they ever come out with our fitment).
        There are rumors that the new ZR1 might use this blower too.

        I had no idea the difference was that large. Wow.

        I'm gaining a lot of respect for these blowers. I fell into the trap of thinking a bigger twin screw was always better. That is not necessarily the case. You need to pair the blower to the application.

        Very common trap.
        Also the reliability of these Eaton TVS blowers are the absolute best, they are the only rotor packs out there designed for 100k+mile service life of hard abuse.
        And they are very efficient and don't generate a ton of heat.

        I saw a CTS-V that was built by a certain shop with a 3.6L Kenne Bell and it made $#@! for power (like only 700whp) because the intake temps just cruising was in the 160's and in boost at redline they were well above 200 degrees lol.
        The new shop building it taking off the KB and putting the ported stock 1900 TVS back on and should make well over 800whp.

        These TVS blowers certainly seem to be more efficient. Numbers from some of the smaller blowers are topping the big whipples. I don't get it exactly as at high boost the Whipple should dominate.

        Its usually that the packaging for the big blowers don't allow a big enough intercooler brick in the V of the engine.
        So you are actually better off porting the smaller more efficient blower, spinning it faster, and making less heat.

        If you are using Methanol as fuel then heat doesn't matter and the bigger the better. But even with E85 its better to be efficient.
