This clean LeMans Blue E46 M3 came to us in pursuit of more power. Before we did anything, we strapped it to our Dynojet to get a baseline read. In its naturally aspirated state this M3 put down 263whp and 223wtq SAE, which is average for these cars. After we finished installing the ESS VT1-445 Supercharger System we did another dyno session to see the results. Although the VT1-445 is ESS' entry level system, this M3 still managed to put down 361whp and 266wtq. Thats almost a 100whp gain and it now makes more torque than it did power when NA.
