Skunk2 – Ultra Series Stage 1 Camshafts BMW S58 G8X M2 M3 M4 21+
Description:
Skunk2 Ultra Series Stage1 Camshafts for BMW S58 significantly increase engine efficiency and power output by utilizing advanced lobe profile designs that retain full Valvetronic and Double Vanos functionality which results in the widest power-band with the smooth drivability and idle. For the ultimate in precision, strength/rigidity†, Skunk2 Ultra camshafts are machined from forged solid 8660 alloy steel blanks that are then rifle drilled, induction hardened, and CNC precision ground.
Expect gains throughout the rpm range with a minimum of +6% to +10% gains from 3,500rpm all the way to redline (S58 @ 40psi dyno gains of 100HP, 100 ft.lb TQ). Though Ultra Stage1 cams are compatible with stock OEM valve springs, we recommend the use of Skunk2 upgraded valve springs (PN: 313-14-1000) along with titanium retainers for the S58 as long term durability using stock valve springs is unknown.
Disclaimer:
It is the responsibility of the engine builder to check piston to valve clearance and establish the minimum exhaust centerline tuning limit for each varying combination. Over retarding exhaust cam timing will cause piston-to-valve contact.
†When pushing performance, all OEM S58 camshafts are prone to bend due to the thin cam barrels designed to save weight and cost. Skunk2 Ultra Camshafts are made from high strength alloy steel and feature a thick-wall barrel design to better resist camshaft flex.
