I plan to put in an optical sensor driven by the speedo gear; pulses from it will be used to control a DC motor to spin a speedo.

so if your not trying to match it to a mechanical speedo i just need to dig a book out to find out for you maybe tomorrow tho
would it not be easier to use an optical type sender pointing at either the prop as in the didgidash or at a hub bolt as in rally car trip meeters
