W2 408 Dyno results today !
I’ve never tested with this arrangement.
But for a typical street strip build....... frankly, it looks like “TMI” to me.
We have two O2’s...... one for each side.
With that much A/F data, seems like you could easily lose track of other aspects of tuning the motor and spend too much time chasing distribution issues around........ that aren’t easily corrected with simple carb changes.
Perhaps I’d have a different take on it if I used a set up like that for a while, but I know how quick a day on the dyno gets used up........ and there are other things I like to go over.
Generally, I chase the jetting around based on power output, and primarily use the A/F ratio numbers to verify things aren’t getting lean enough to hurt something.
Most combos don’t make the best power when they’re lean enough to hurt parts....... so if you tune for power, they end up safe.
But, occasionally you run across one where you have to be careful and know when to stop leaning it out.
My gut feeling is, based on the O2 readings and bsfc numbers, if one just ignored the A/F ratio numbers and just tuned for power....... there were some ponies there for the taking.
