Tested on a dyno, my Cummins picked up 27hp with equal length plug wires!! Now everyone get some, you read it on the internet ;)
it's not fully light speed . about 80%
electrons travel in the wire at a quite slow speed opposite the direction of the current. the speed of electricity however is very fast it's actually the speed of the propagation of the electric field
The value of the "speed of light" that everyone is kicking around is for the speed of light in a vacuum -- that is not the same thing as the speed of an electron in a metal wire. But the point is the same -- it's way too fast to worry about the differential lengths of spark plug wires.
It's about resistance, not traveled distance.
It takes time to send electrons through a wire and build enough current to jump a spark at the plug. It takes (a fraction) more time to build more current to push electrons through a wire with resistance.

This is the first time I've ever heard anything about this. Ridiculous, I think it's not even worth thinking about.
I saw a prototype ignition system in a speed shop back in the 80's. The guy took a gm HEI distributor housing and mounted 8 (yes eight!) sets of points around the outside (yes outside) of the housing. The primary wires went to 8 coils mounted on the valve covers. One coil and one short wire for each cylinder. He was trying to increase coil "soak time". Think about how many times a single coil has to fire in a motor winding 8 grand. I discussed this system with him then showed him my bike out in his parking lot. Unlike Harleys and most other makes, my Triumph Trident had 3 cylinders, 3 sets of points, and three coils.
Uuhh new? I'm talkin 30 years ago and a 60's bike. And yes, it wasn't new then.Not new, in fact one of the first ignition design types. Model T's used this with coils in wooden boxes. What we think of as the "normal" points system was developed by a GM Engineer named Charles Kettering.
Not new then, not new now.Uuhh new? I'm talkin 30 years ago and a 60's bike. And yes, it wasn't new then.
Did you make those runs back to back on the same day at the same track, with only that one change in between them?
