When the optimum rpm is found, how do those of you with a four speed shift? Ill use a the term a friend keeps asking me about.
"Are you power shifting"? Keeping the accelerator to the floor and stabbing the clutch for the gear change. I don't, to me it just seems unnatural, I cant keep my foot planted while trying to shift. Now if you have a "smooth" shifting transmission, and possibly a rev limiter it may be worth trying, but I still cant bring myself to try it. I have seen a you tube video of a guy doing it in an old dodge or Plymouth.

Since I started racing four speeds in 1977, once I put the gas pedal to the floor I don't lift and I use the clutch, but you have to have near perfect reflexes and coordination. If you let off during shifts then you lose as much as 2-4 tenths. Guys like Ronnie Sox and Dave Strickler were the best on four speeds that ever was.

Like this Mark gettin' it done with a little 302 and a Nash 5 speed with 1:1 5th and 5.38 gears, using a clutch and standard "H" pattern type shifter. Nothing fancy.

I think you are getting confused Adam, its torque at the wheels that matters. Holding first to get more torque to the wheels is more important than the engine running at peak torque after the shift. You got it right the first time.

One of the reasons I prefer to think of it in terms of HP. Less confusing and more intuitive.
