I am enjoying learning as much as i can about the cologne engine (and engines in general to be honest) but i have a question I'm hoping you can help with.
So the new camshaft i've bought is supposed to be a 'fast road' profile but when i compare it to my existing cam (on the right of the picture), my existing one looks 'flatter' giving a longer duration - ?
By contrast the new camshaft (the one on the left of the pic ) looks 'sharper' and therefore looks like it will have the valves open shorter than the one.
from the language I am using to describe the different camshafts you'll know i'm a novice when it comes to this stuff - but hopefully you see what I mean - ? I don't understand how the new camshaft will open the valves for longer based on the shape i am seeing. But is there something in the angle of the cam that i don't know about I wonder? The camshaft was made from a blank and the same place i got them did an absolutely lovely job porting my cylinder heads.
Grateful for any advice you might have for me - thanks all !
