Standard camshaft profiles

[sdibbers]

Does anybody have info on the lift, duration and timing for a standard 2000TC camshaft they can share?

All except the lift are in the manual, but you probably want more detailed information. Are you thinking of creating a 'hot' camshaft? Valve timing is 14-46-44-16, so all four degrees retarded from the SC settings to move the torque band up the rev range. Same camshaft, different positioning relative to the crankshaft. But you knew that…

Hi John, thanks for the reply. Yes, I’m looking to compare the standard to the piper fast road regrind.

Edit: looked through the manual but no listed duration (I may be just missing it).

Piper grind is as follows:

Duration Inlet	260°
Duration Exhaust	260°
Valve Inlet Lift	.410" 10.41mm
Valve Exhaust Lift	.408" 10.37mm
Timing Inlet	26 – 54
Timing Exhaust	56 – 24
Full Inlet Lift	104°
Full Exhaust Lift	106°
TDC Inlet Lift	.078" 1.98mm
TDC Exhaust Lift	.066" 1.67mm
Valve Inlet Clearance	.010" .254mm
Valve Exhaust Clearance	.012" .305mm

Valve timing is 14-46-44-16,

The duration of the std cam is 240 deg, both inlet and exhaust. ( 14 + 180 + 46 = 240 )

Doh! I should’ve worked that out. Thanks John.
