Dynojets and other dynomometers measure torque, ( twisting force on the drum ) and calculate horespower. Your equation is the exact equation the Dyno does...

Doh! Thanks for the correction Doug. I didn't think about it long enough obviously. Hopefully I'll be getting my silver "L" soon and I can meet up with the local group.

Later,

Chickenears...aka Tim

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

DamonH,


torque = john(me)*(1/scratching head) + (10(confused)

Never was any good with algebra...


OMG thats funny as **** - hahahahahaha.

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!!!
