My tuner suggested my shift points on the street side to be set at 5200 and on the race side at 5600. I explained to him that I wanted my truck to preform on the street but not at the expense of a blown motor. There will allways be somebody faster, so I don't care/want to be the big dog in the Lightning family. BTW, our engine mods are the same, except I run a stock exhaust

What Doug said, A dyno measures torque and HP is computed...
From a powertrain guy point of view, HP is a ficticious number, Torque is what counts when doing any calculations on powertrain parts.
Now to show off my engineering prowess....
How to design a clutch...
Calculate Engine Inertia Torque during shift
A=(n(max)-N(Clutch)*2pi /60t=(5600-2200)/2pi /60(.75)
calculate torque to clutch during shift
((t=ta+ta)tc)
Calculate work per minute
Wt=Tt(2pi (N(max)/2)
Well, the whole thing is about a page and a half, if you're really interested, let me know and I'll e-mail it...
I have 2 graduate degrees and I still have to use a cheat sheet to do it myself..

Well lets see, after algebra II I took statistics and logic and other fun maths cause I thought all that advance crap was useless, oh well.

Greg is to technical!!!!
Just have your chip set to 5550 or 5600 and let her fly man!!!
