Camshaft centerline VS peak lift
I am going to be degreeing my skunk2 s2's in and I am confused as to what the difference between peak lift at the spec given VS centerline is. On skunk2's website(my sheet only has opening and closing) the cams spec's are:
Intake: Peak lift 94* ATDC
Exhaust: peak lift 112* BTDC
103* centerline
I was under the impression you rotate the crank till you reach the specified crank degree the cam is at peak lift, then adjust the cam till it reaches peak lift, but I also read the centerline is the crank degree the cam is at peak lift. What am I missing here?
Intake: Peak lift 94* ATDC
Exhaust: peak lift 112* BTDC

Re: Camshaft centerline VS peak lift
forget about peak lift you just need to get the cams adjusted to numbers and the lift they spec on the cam card

Re: Camshaft centerline VS peak lift
Do both and see if they match. The .040 number is better. The radiused rocker and installed height, # of valve jobs, valve length, etc. etc. etc. can change the peak number, pus it lasts over several degrees, so you need to have done it a lot to understand it. 1mm opening, 1 mm closing and the math is alot more accurate to mfg. specs.

Re: Camshaft centerline VS peak lift
I gave you a resource to possibly find the answer to your question but I am a hater?
This is a great example of why people dont bother helping others on honda-tech. If someone doesnt spoon feed you the answer you start acting like a child. Good luck with your build.

It wasnt his question, and if you understood what I was asking and read that thread then you would know it doesnt answer what I'm asking.
