as Ive already posted thread abt ignition timing and cam timing,,

I just thought I'd just post a pic to give you an idea of what Im doing here.

This is TDC :1poke:

CPS with exhaust cam set at -3

CPS with exhaust cam set at -4

pic shows 3.5 while testing. its at 4 right now

little bit off but its already fixed (just to get the idea)

both cams


and yet im having hard time finding the very very very fine invisible line to set the timing!

it idles at or around 620~720 with ex -3 and 660~800 with ex -4

intake always at 0, didnt want to move it +1 unless I set timing first.
any comments?

[DigitalDUST]

no, its unorthodox racing.

ahh cool. set with a timing light?

iirc the gears are cam * so its its 2x for the crank *

 

[DigitalDUST]

set with timing light. of course yes

I wish one of you guys just come and give me a visit, I'll buy you beers or something just to listen to it and see what I mean.

niether do i.

I think he meant for every 720 degree of crank rotation the cam rotate 360 degrees.

A 2:1 cam to crank rotation ratio.
