This is the Cat Cams adjustable cam gear for an 8v douvrin motor.
Its pretty sexy, and far too nice to hide under a cover.
I'm getting a bit ahead of myself here but have started thinking about the challenges I might find ahead of me.
I'm not worried about dialing in the cam the first time and locking it down. I'm pondering the bits that come after that.
All the timing information for the ecu gets generated on the other end of the cam.
I was planning ahead when I gutted the dizzy and built my sensors, as the sensor locations relative to rotation are infinitely variable within the housing, and the whole dizzy housing can rotate too, giving global adjustment once the sensors are locked down.
With a bit of luck, I should be able to effect a change on the cam gear and recalibrate the dizzy back to the the flywheel with a timing light.
On that note, I'm going to need to make up a more accurate pointer on the flywheel.
Once it is timed to OE spec and locked down, marking it somehow would be good.
Can anyone offer any advice how to mark it up??
The blue middle is anodised alloy, and the outer gear is .....steel? ...has a bit of surface rust.
I'm guessing its going to be easier to mark the alloy rather than the steel, but how do I mark it accurately??
Would it be good to set it up in a mill and use some type of stylus to mark it and achieve angular accuracy using the degree counter on the mill bed???
Or is there a heaps easier way, like buying/making a vinyl self adhesive protractor of the right size and sticking it onto the front face of the cam gear and gluing a needle onto the outer ring.
