REMARKS :
#
- steel billet camshafts
#
The VANOS (VVT) system on the intake camshaft changes the PD from 120° to 80°. The data are shown for full intake retard (disengaged VVT).
The VANOS (VVT) system on the exhaust camshaft changes the PD from 105° to 80°. The data are shown for full exhaust advance (disengaged VVT).
Check distance between valves and piston to be 1mm at least with VVT engaged. Wrong installation will cause severe engine damage!
#
FOR COMPETITION APPLICATIONS ONLY. Following details must be verified:
-
the camshafs must turn smooth in the cylinderhead, provide free travel by machining where needed
-
distance between valve seal and retainer at full lift must be 0.6mm at least
-
minimum valve spring travel of 1.0mm at full lift must be provided
-
distance between valve and piston 1.0mm (pref. 1.5mm). check 5-15° before TDC on exhaust, and after TDC on intake
