  • I see you labeled this video as the "most powerful Challenger in the world", but I dont see anything in the video to support the claim. Can you update the video by showing us the Dyno screen after the run is complete? I have personal knowledge of a Challenger with a 426 cid enginge that dynos over 1000 RWHP, so I am sceptical.

  • @bodagrunt If you look at the date posted, this was by far the most power Challenger at that time when we first built the car. We were years ahead of our competitors. This particular Challenger has since had the power turned up some more and sits well over 900 rwhp now. We have other SRT-8 packages making well over 1000rwhp as well. We not only build high horsepower cars, we also build them up for street and track use. We have some awesome race cars as well.

  • how much did it cost

  • @lolurded99 This particular package runs around $50k with options

  • cool, i got a speedfactory stage 5 with a magnaflow double twin tip exhaust custom 7 speed double clutch tranny, is the setup used in this video sold?

  • @Matts44444 We have about 20 different SRT-8 base packages we work off of and we can modify and build custom packages to tailor them to the customers requests. 1000+ horsepower packages aren't for everyone so we have packages for every power level.

  • @insanity824 wheres the vids

  • ummmm My Challenger is twin supercharged, stage 5 intake. Stage 5 twin titanium exaust, ECU, and Stage 3 engine tuned, it puts out 1066 HP. tops at 269 MPH . and its a V8 7.5L hemi powered American Muscle and 8 speeded. SRT8, and It Can Power 0-60 in 1.9 seconds!!!! My Challenger is Beast.

  • Might as well put a mopar 540 in the thing then you'd have over 600hp and it would have been nice to hear the amount of horsepower you got out of it after the dyno.

  • Nice car. How does it compare to the twin supercharged 440 Charger?

  • @jmcrides03 your focus may have a hemi, but it's still a piece of crap

  • From 0:31 to 0:36 everyone in the room lost their anal virginity.

  • Hey your just mad cause you don't have shit

  • that got a six pack

  • pretty cult energy built a 6.1 with a blower in march of the same year with over a 1000hp and then a year later redid a challenger and put a 440 stroker blown that has over a 1000 also,
