Here's what i think.
That auto car for example, lets say peak power is at 5500 rpm with the 3.50 gears it would finish the 1/4 at 4700 rpm with the 4.11 it would finish at 5500 this is the reason for the much better ET's.

My Z peak power 6900rpm with 3.45 i finish in 3rd gear at about 7400 rpm
With 4.10's i finish in 4th at 6800 below my power peak so either i god with 4.33's or 4.50's
My Z looses about 15hp from peak (6900) to 7400rpm so not much loss.

Also i did not mean going into 6th i meant going into 5th i know you don't feel it much but trust me car does not pull as hard in 5th if you shift her at 7k rpm it drops way below peak power down to 5200 rpm what you have to do is run her to 74-7500rpm just to get her closer to peak power going into 5th.

I went from 1.74 60ft to 1.59 you would think 1.5 at 60 foot would get me 2-3 tenths i can't shift that fast so i loose it at the extra shift even if i got 11.00 it still did nothing for me.
