Did we confirm if it's going to be 2 runs or 3 runs?
Looks like the 350z guys did 3rd gear for AT and 4th gear for MT runs last time. I'd like to get 2 runs in 3rd, and 1 in 4th if possible with 3 runs.

Hey guys I hate to be a flake but I had a meeting come up today for Saturday at 10am for work. I really wanted to do it too. If you guys are still down there ill try to FLY down

dynoday is a bunch of guys gathering with their cars to find out how much horse power they're running.
A dynamometer, or "dyno" is an instrument which measures the output of an engine. There are two main types; an engine dyno and a chassis dyno.
Engine dynos measure the output of an engine directly. The engine is removed from the vehicle, and is placed on a test stand, where it is hooked to the dyno.
Chassis dynos are much more practical, because they allow the engine to be tested without being removed from the vehicle. Unfortunately, they're not as accurate, as there are power losses in the driveline as well as from tire slippage. Newer dynos, however, can compensate for some of this by performing a run-down test, which we'll explain later.
To have our cars tested on the chassis dyno at MT, we drove our cars up two ramps onto the equipment. The front wheels (because our cars are front-wheel drive) rest on two big drums which turn freely. The car is secured in place by several mounting straps. After tightening the straps and making whatever adjustments necessary to the computer, the operator gets in the car and slowly accelerates until he hits about 2000rpm in 4th gear. After hitting a button, the computer then begins its measurements. The operator presses the gas pedal to the floor, and keeps it there until the engine is at redline.
The computer measures two things: the speed of the engine, and the speed of the rotating drums. The computer knows how much the drums weigh (and therefore how much power it takes to accelerate them), and plugs all of its information into a simple formula which determines the output of the engine. The results are graphed against the speed of the engine, and there you have it!
On the Scirocco, we did a coast-down measurement, which gives a good approximation of the power lost in the driveline. Once the engine reaches its redline, the operator quickly lets off the gas and engages neutral. The computer measures how quickly the drums slow down, and from that data can tell how much power it takes to turn the wheels, axles, and transmission. That number is about equal to the amount of drivetrain loss
IS THIS THING STILL ON ???
