was one ever built?

MOTOR TUNING RS50 (v.1) 505HP E39 [S62 B50] M5
SKU:142 62 50 394

Revised internal components allow the RS50 to reach a staggering 8.800 -1/min. New camshafts, a revised valvetrain with larger exhaust valves, and higher profile cams, allow the RS50 to breathe better and pass the 500 HP mark with ease.

The RS50 includes an exhaust with tubular manifolds, X-Flow down pipe, and rear silencers.

98 octane petrol is recommended.

8800rpm is an insane number, especially since Dinan only raises the rev limiter to 7300RPM & Nowack only 8000RPM

the Nowack N500 ...they where each other's Doppelgänger

gotta admit 8000RPM out of the S62 sounds ridiculous

Nowack went to 7580 rpm.

8800rpm - no way. I think that's a type. 7800rpm more like.

that's a pretty bad typo for it to survive since at least 2006

i think the home depot intakes are because the engine is in a smaller car (E46?) not the E39

... as for the intake it's the first painted one i actually like and would consider

JohnAnthony will be the fastest with his radical rear diffuser delete weight-saving mod. Light as a feather!


I'm just getting headers to make the car like it should've been, instead of the 540 headers. I won't ever be supercharging the car.
