It depends on the primary supply voltage, the individual coil, capacitor and the rpm (interrupt frequency) what the voltage spike will actually be. I have measured 300+ on a scope.
If you are worried about capacitor quality, try one of those brass things Tubman makes. They seem to match most coils found on model A's.
Thanks Pete. You got the numbers, you're the man!
I always worry about product Quality...it's fused into my DNA.
I'm not familiar with Tubman. They make caps?
