Ed's 426 HEMI Powered, Arrington Supercharged 2011 Challenger RT!

2015 RAM 2500 - supercharged

We welcomed back another old friend to the Arrington shop recently. Even though it has a different owner, this one was supercharged by Arrington a few years ago. Ed bought it with a plan to take it even farther. So it came back to us for a 426 short block upgrade and a smaller supercharger pulley. Now he can go play with the Hellcats and show them who is Top Dog.

We also put on a larger TB to let all of that higher air flow through, upgraded the camshaft, and got great results even with the stock exhaust and stock heads. To handle that extra power, we also put in a new ProTorque converter and a Southern Hotrod upgraded transmission.

The result is a thrill ride and one of the most powerful RT versions we have ever done. Enjoy.
