450 WHP ‘Horsepower Freaks’ Turbo BMW E46 M3 – One Take

This BMW E46 M3 features an aftermarket “Stage 1” Turbocharger kit from now-defunct BMW Tuner, Horsepower Freaks. While certain kits were available up to and over 800 horsepower for the E46, this street-tuned kit makes a healthy and, apparently reliable 450 wheel horsepower. It’s quite a ride!
