Back before I acquired my own dyno I used to pretty much follow the other place's procedues - something of a courtesy since I was in "their house". Now that I have my own DTS cell I get to decide.

Much of my process comes from Engine Masters procedures, and I sort of stick to that range for consistancy's sake. Depending on the year, they go from 2500 or 3000 on up. Even with my water pressure cranked up to 70+ I can have a hard time holding a torque oriented engine down to 2500 - so 3000 is a better and smoother place to go from and I don't go lower any more unless its a mild street deal. It's hard to hear detonation in a dyno cell, much less a car before you've already done some damage. A styrofoam coffee cup on a 20 foot long piece of copper tubing bolted to the engine and routed up near the console will really startle you - it's a rattle amplifier.

I have a non-FE mounted to the dyno right now that will probably not load below 4500...
