I'm planning on hitting up goodspeed performance and getting some dyno numbers of my own soon. They have a MAHA dyno which is supposed to be one of the best dynos out there and measures actual drivetrain loss instead of guessing a static number, since drivetrain loss % will depend on a whole lot of factors. Has anyone ever used one before? They say that a stock e46 M3 will put between 332 and 334 crank horse power on the MAHA dyno all day, factory numbers are 333 so I think its gonna be pretty interesting.
