REMARKS :
#
- camshafts for use with VVT on intake (like original)
- adjustable sensor ring [ref. 93-55001] on intake camshaft included
#
The VVT system on the intake camshaft changes the cam timing continuously (and so the lift at TDC):
-
1st intake valve: 140° (disengaged) // 97° (engaged)
-
2nd intake valve: 144° (disengaged) // 101° (engaged)
-
1st exhaust valve: 110° (no VVT)
-
2nd exhaust valve: 106° (no VVT)
The centerlines are identical to the original camshafts.
Please make sure there is enough distance between valve and piston when the VVT system is engaged.
#
VVT reprogramming, operating range adjustment or even eliminating the VVT system should be considered for camshafts with increased duration
#
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
#
ONLY for use in competition engines with independent engine management (throttle position sensor) or carburettors
