Adjustable Cam timing

Post by Alaska »

Advice required,
Can you share what degree you have set your inlet and exhaust cam.
I am going for inlet - open 35 degree BTDC, close 65 degree ABDC so duration 280.
Exhaust open 65 degree BTDC, close 35 degree ABDC, duration 280.

I’m allowing the 1mm and valve clearances within the class open as 1mm after starting to open

The valve to piston I’m using
Inlet 1mm 12 degrees ATDC, exhaust 1.5mm 12 degrees BTDC

Thanks for any help chaps
