Hi Richard,
I am unsure of the SR situation, but Errol has done the same thing
with the CA (fwd to rwd), so perhaps it is do-able.

side of my HEI
and thus the original coil and =izzy. After a couple of weeks I then swapped to the
other side of
the HEI to =heck that half of the circuit. Then I could be sure that when I =onnected
two coil pac
ks later down the track both would be sure to work.

I =nstalled this on the engine as outlined in the kit instructions. This made a =uge
difference to
performance (my dizzy had a max of 7deg advance and no =acuum advance). But the
dizzy was still b
eing used for a trigger source =nd spark distribution.

>it behind th
e front pulley. Then I removed the front pulley drilled two holes 180deg =part and
glued magnets i
nto the holes.

magnet. = was then able two run the car off the dizzy but look at the waveform
created =y the hall
effect sensor to check that the timing of these events were =ccurate. Then I was
able to design a
nd build a circuit using a microprocessor =hich basically divides the output of the
PIT (coil trigg
er) into two.ie two coils.

system.

y =esign, dual coils), Jaycar PIT, hall sensor, coil trigger unit (my design), =oils
packs, wiring
kit and detailed instructions.
