ScrapLifeLee and his crew are either committing the biggest sin in automotive history or they're kickstarting a whole new trend we never saw coming. Heck, maybe it's a little bit of both. Either way, it's working. I'm speaking, of course, about their Honda-powered Hellcat project. No, you didn't read that backwards, those nutcases slammed a Honda engine into a 2021Dodge Charger Hellcat Redeye. Not only did they get it running, but it ultimately cranked out more than the original 6.2-liter supercharged Hemi's 797 horsepower, and even blew the tires apart on the dyno. Honda-Swapped Hellcat Makes More Power Than Factory ScrapLifeLee, YouTube The ScrapLifeLee YouTube channel just uploaded the latest entry to its Honda-powered Hellcat series. This project started when they got their hands on a 2021 Dodge Charger Hellcat Redeye, that the original engine was taken out of. Rather than going back to a Hellcat V8, they decided now's the time to shave some weight off the front. 340 pounds to be exact, because that's how much lighter the K24 Honda engine they opted for is.Don't come into this thinking they're slamming some under-powered economy-minded four-pot in this Mopar. The K24 engine is a seriously stout piece of equipment with the right upgrades. They're known to crank out 1,000 horsepower with boost and can scream out to 9,000 RPM. Maybe not the cylinder configuration you'd expect in a Dodge muscle car, but it's got more than enough power potential to get this thing moving in a hurry.That kind of power advantage is also magnified by the weight savings, which is something these Hellcats are in serious need of. With a curb weight of 4,600 pounds and being nose-heavy, they're anything but nimble. Dropping a few hundred pounds off the front end and picking up a bit of power is a major step in the right direction toward improved weight distribution and a better power-to-weight ratio.ScrapLifeLee, YouTube In the video, Lee and the crew got the car driving under its own power, proving that the swap is totally doable. They even made a small trip through town. When they strapped it to the dyno, however, things got ugly. It did make more than 720 horsepower at the rear wheels on 44 pounds of boost, which is more than what the original motor would have made, but they ended up blowing the tires right off of it.No, 720 horsepower at the tires shouldn't be enough to decimate tires like that and it's ultimately not what's responsible. It's the fact that the rear differential in this Charger Hellcat is a 2.62:1 ratio. When they did the final dyno pull with the direct-drive gear selected on the transmission, wheel speeds exceeded 250 mph, causing the tread to pull apart. The silver lining is that swapping to a shorter gear will solve the issue while drastically improving throttle response. Shot Tires Are Just The Start ScrapLifeLee, YouTubeUnfortunately, dead tires aren't the only less-than-desirable result of these Honda-Cat dyno pulls. The 8HP90 transmission also wasn't up to the task. As much torque as this unit could handle, RPM is the limiting factor. It's not recommended to exceed 7,500 RPM, which the ScrapLifeLee crew is already surpassing. At least, those torn-up tires didn't touch the new TE37 wheels the Charger has been outfitted with.Both the transmission and the differential are yanked out of the Charger by the end of the video. If they want to continue to dial this thing in, they need to source a diff with a shorter gear and a transmission that could handle the revs. While that'd be enough to stop most of us in our tracks, we're sure it's a mere speed bump for this group of mad scientists.
