For me this is more of a academic question but anyway.
Lets assume that you have access to dyno with datalogging for a/f ratio, throttle position or manifold pressure, rpm, and exhaust temp.
The things you could play with were :
-basic carb tweak (needle, jets)
-timing (base and advance)
maybe even things like trying a few different exhausts or airbox/filter designs
How would you (or a pro) proceed? I am assuming that there are so many interconnections from one adjustment affecting another that you would need to proceed in sort of circles.
For example after base values
Tweak A until good -> tweak B until good -> tweak C until good -> repeat (as C might have thrown A off)
('until good' meaning you get most satisfactory result)
How do the pros do it? basic fuel ratios 1st and then tweak timing and go back to fuel?
It seems that there might be some kind of routine that would make the whole process less guess work. We all hear from the dyno sessions where huge improvements are done. Where could I learn from what exactly is being done. I am sure experience is king as always but any tips or links to good reading material would be much appreciated.
