465 wheel horsepower Stage 3 RMS supercharged S52 M Coupe

[Sticky]

Great build here from RMS (Race Marque Systems) that is putting down some nice power out of the S52 inline-6. The vehicle is an M coupe which was available originally with the S52 shared with the E36 M3 and then later with the S54 from the E46 M3. The M coupe has one of those love it or hate it designs but this is definitely an enthusiasts BMW and it is a shame BMW has not built an M coupe based on the current Z4 as they did with the previous generation.

This is a built motor car with forged low compression internals. The Stage 3 supercharger setup produces 16 psi at redline. The car features meth injection courtesy of an Aquamist HFS3 system.
