well his torque begins to drop after 4100 rpm and I know he shouldn't be shifting that early. [Confused]

His torque falls off faster after 5000 RPM. Try shifting there, The only way to really find out is in real world driving but that should be a start.

I know I'm not that far off on my shifting speed to where I'm loosing 2mph. When I started short shifting my mph started to go up. Will Rearend gears make a difference in how these calculators figure out shift points?
well all I can say is TOTAL CAR WIEGHT

not takeing anything from drew's driveing skills. we now drew wieghs next to nothing compared to most people on here. so no matter what you do he will always run alittle faster then you. Un less you can get the car to weigh the same when eithere one drives it.Then that would show you whos the better driver.

measured values are nearly always more precise than calculated values when doing math...
depending on your equipment.

sawson, you should ask your calculus professor which way is best (to perform the shift point calculation) and WHY...
