Sound Performance built turbo S54 E46 M3 puts down an impressive 1070 wheel horsepower on a Mustang dyno with ProEFI standalone
Very nice numbers here from Sound Performance with their turbo E46 M3. Now that Horsepower Freaks is officially dead
and people are fighting over what remains the door is open for tuners to take the reigns of the turbo E46 M3 market. Sound Performance appears to be one of those stepping up to fill the void and this is quite a way to do it. How does 1070 wheel horsepower and 830 pound-feet of torque at the wheels on a Mustang dyno sound?
This is definitely one of the stronger E46 M3's out there as although they exist there is just a handful in the four digit wheel horsepower area. Very impressive and much respect.
