Hemi owners rejoice! After long last, the Magnuson TVS2300 supercharger is finding its way onto the 6.1 in a big way: To the tune of 544 rwhp and a wicked torque curve that pulls the big-boned LX platform (and in this case, a 2010 Challenger SRT-8) through the gears.

The new staple of our supercharged HPE600 Challenger upgrade, the TVS2300 blower does for the Hemi what it’s been doing for the new Camaros for months. Namely, transforming a 420-something HP piece of modern muscle into an all-out street brawler.

With our HPE600 Challenger on 93 octane fuel, it put down 544 rwhp and 512 lb-ft of torque at 8 psi. On the standard pulley, making closer to 6 psi, it was still knocking out runs at 508 rwhp and nearly 480 lb-ft of torque.

All this on a brand new Hemi with only a few miles on the clock. Once the car gets a few thousand miles under its tires, the potential will only open up as the motor gets fully broken in.
