This time was no different. We went straight to our load test, which consists of pulling 5th gear to redline, pulling the engine down to 4000 rpm with the dyno brake, and then pulling back to redline again.
Do you bring it down slowly or quickly? Hold it at 4k for a little? Let it go back to redline without restriction?

I'm trying to duplicate track conditions when I do it, so I operate as if I'm shifting. Redline - clutch - dyno brake to 4000ish - release dyno brake - release clutch - pull back to redline. I try to do the whole thing as quickly as possible, but the dyno won't pull down as fast as you can shift.
Make sure the car is tied down really well when you do this, as the loads shift more during that simulated shift than they do during a normal pull.
Also, make sure the dyno has a really serious fan, or else you're not simulating anything real at all. MD Automotive has 2 hp, 4' diameter monster that blows 60 mph. This is what a dyno needs.
