Continuing ignition timing debate from the 416 thread.

Again, that is a sweep test and you are talking about less than 1 hp between the two.

I guess you need to explain to me how the engine wants the same timing at peak torque and peak power, because the ONLY way that can be possible is if the VE is the same at both points.

And if they are, why is that? I mean we agree that a higher VE requires less timing don’t we?

Timing requirements are affected by a multitude of factors. I can't tell what factors are in play here. I'm just showing you the result of all those factors.

You can say that my test isn't valid because it isn't a steady state test. But at one point you claimed differences in timing can't be measured on a sweep test on a chassis dyno
Then you built a distributor with a curve and tested it at that same chassis dyno and when it showed a power increase now all of the sudden the numbers are valid. When the dyno operator put a locked distributor in the motor and it lost power on a sweep test you claimed that it validated the fact that your distributor was better. On the same dyno that you said couldn't be used to evaluate Timing curves because it sweeps too fast. I apologize if I seem skeptical but should we believe the results from that dyno or not?
