anyone run an M5 against a 540i wagon (automatic!) with a Dinan supercharger? supposedly a local guy has raced and beat E36 M3s, and recently an E46 M3 (who knows the M3 driver skill level...), but I would think an M5 would clean it's clock if driven properly. I'm thinking about inviting him to meet at a local racetrack here in So. California and see what happens vs. some REAL competition...
