E36 3 Series and E34/E39 5 Series Performance Camshafts

Riot Racing developed regrind camshafts are yielding dyno proven 17whp for the S50/S52 M3(see Dyno page). For our M50/M52 regrind cams, we have used a similar cam profile as our S50/S52 regrind cams.Our cam profile is proprietary but what we can tell you is that we have the most aggressive cam profile that is safe for the factory camshafts. The goal was to achieve increased horsepower and torque throughout the rpm band without sacrificing the drivability of the vehicle. Rather than focusing on peak horsepower we emphasized on more mid range power to yield street performance. A software upgrade is not required with these cams
These regrind cams come with a lifetime warranty. Core exchange program requires good condition factory cams of the same model purchased

Applications: 1992-1999 6 cylinder 3Series and 5 Series (M50/M52 Engine)
