What do you do when you already have a completely stripped down, fully caged, carbon roofed, Lexan windowed, custom built, non street legal track machine? Supercharge it. While this hardcore E46 was at our facility we had the opportunity to install an ESS VT2-550 supercharger system to bump this ultra-light M3's power output from 289whp & 242wtq to a whopping 493whp & 335wtq! To aid this beast in putting down its new power, we installed a BimmerWorld carbon fiber front lip, front race splitter and rear race spoiler for some much needed downforce. Watch the dyno video and be sure to check out all the little details and features of this dedicated track toy. Enjoy.
