OK guys,
These questions are aimed at all of you who have aftermarket cams and adj cam gears fitted... (basically I am wondering what sort of cam timing on what cams, let's say HKS 256I/264E for example on a single or maybe even BPU, has given an optimum torque curve).
Have any of you actually timed the cams in 100% by using a dial gauge to find TDC and then using a cam wheel to set the cam exactly as recommended.
Further to that has anyone had their motor on a dyno or rolling road and adjusted cam timing to get their optimum torque curve from that initial setup?
It seems to me a lot of people fit the cams and leave the cam gears at zero and call this - "zero". Similar to a lot of the young guys on SF do when they fit cams, they then start saying..."+1 on the intake and -2 on the exhaust did xyz" then someone else goes off and does the same. Well given the manufacturing tolerances on the cams, crank, gears, belt etc these two motors probably won't be timed the same at all and yet people seem to think they are.
So who has dialled their cams in properly to the HKS/JUN/BC timing sheet and have you found any benefit in advancing or retarding from there on your particular setup?
Cheers
Dan
