What carby are u running? i got my turbo running through a 350 holley, my vacuum advance runs to the carby where it usually is. I'm currently modifying a n12 pulsar elec. dizzy to put on.

edit: mines a blow through turbo on a Worked A14

Basically lock the vacuum advance plate so it doesnt advance the timing with vacuum, only mecahnically advancing. Then you set a higher base timing and play with the mechanical advance slot, springs and weights to get the correct advance curve for your cam. Not a exercise to be undertaken without some knowledge of ignition systems.

so how do you lock and graph the dizzy

turbo....advance

not on the same engine, usually have the dizy locked and regraphed

probably be a valid question if you are running a booster, but then it gets vaccum off boost anyway

i was talking to bundy today and he brought up a valid point. 'were will i get my vacuum for the advance from when the turbo is hooked up'. its on a A series blow through setup.
