Build Story

The Hellcat platform is one of the most tuner-friendly cars Dodge has ever built. My 2021 Redeye started at 797hp from the factory — I wanted to see how far I could push it without touching internals. The answer: 850whp on a conservative tune with just bolt-ons and a pulley swap. The drag radials were a game changer — went from 11.4s to 10.6s just by swapping tires. This car is my weekend warrior. It lives in the garage during the week and comes out every Saturday for the local test-and-tune. Best 60-foot time so far: 1.42 seconds.
