VRP AMG Belt Wrap Kit – Mercedes-Benz M113K
The VRP Belt Wrap Kit is designed for Mercedes-Benz AMG M113K supercharged engines. Under heavy acceleration, the supercharger belt on the M113K engine can slip on the supercharger pulley, which impairs supercharger performance and reduces the achievable boost pressure.
The Belt Wrap Kit increases the contact surface area between the belt and the supercharger pulley, reducing belt slip and helping to maintain consistent boost pressure even at high engine RPMs.
The kit helps smooth out engine power delivery, and according to the manufacturer, boost pressure can increase by 1–2 psi (approximately 0.07–0.14 bar) at high RPMs.
Updated mounting design
The kit includes an updated three-bolt mounting bracket. The previous two-bolt V-style bracket could flex under load, especially with more aggressive supercharger pulley combinations. The redesigned three-bolt structure improves mounting rigidity.
