R/T Life’s Twin-Turbocharged 397 HEMI 2015 Dodge Charger R/T Widebody!

Our long-time friend and contributor R/T Life, has been on the quest for the most performance possible with his 2015 Dodge Charger R/T and its 5.7-liter (345 cubic-inch) HEMI V8. While there is only so much you can do in naturally-aspirated form with the 5.7-liter, R/T Life is now going to a twin-turbo setup which should really improve the overall performance from the small-block HEMI engine.

Back in December of 2019, R/T Life’s 5.7-liter went under the knife at Jannetty Racing in Waterbury, Connecticut, to create something that would amp up his search for more horsepower. Jannetty Racing took the 5.7-liter and created a cammed 6.5-liter (397 cubic-inch) HEMI V8 out of it. In its naturally-aspirated state, the 397 HEMI made 449 rwhp and 454 lb.-ft. of torque. Now, while that might seem conservative, Jannetty Racing built the engine to handle boost.

Since then, with the help of a custom twin-turbo setup from the team at RZT Performance in West Babylon, New York, the 6.5-liter HEMI also has other improvements like a 392 Arrington Stroker kit, Hooker Blackheart shorty headers, and a Magnaflow xMOD cat-back exhaust system, just tt name a few of the modifications.

The engine now lies inside, a 2015 Dodge Charger R/T which has been converted to widebody status thanks to an IKON Motorsports 2020 Dodge Charger SRT Hellcat Widebody Replica body kit. When it came to tires and wheels, he ended up going with a set of 20-inch x 11-inch Hellcat Widebody replica wheels from Vicrez. With a -2.5 offset and some new Nitto 315s, giving the car the same signature look as a 2021 Dodge Charger SRT Hellcat Redeye.

While the car has to be tuned to be dialed in, R/T Life has said he wants to have the new twin-turbocharged HEMI setup run on 93 octane to allow him to pretty much go anywhere where 100+ octane race fuel is not available. So we can’t wait to see where the build goes next.
