Anybody (probably everybody) know what the average cost is to take a car and put it on a dyno. And what exactly can be told about the car other than hp figures?

Some shops have very little, just a DynoJet style "inertia" dyno, which means you must accelerate to generate load (no holding the engine at X rpm to fiddle with something). These are good enough to satisfy your curiousity, and you can do some rough tuning on them.

These days, every shop should at the very least have a wideband O2 setup, since they're so cheap now. Hooked in properly, you should be able to get HP/torque v RPM and AFR v RPM. Some shops may be able to datalog other sensors, too, like engine temp, manifold pressure, etc.

Make sure the place has a big fan to blow into the nose of the car, to vaguely simulate airflow at speed.

Price can vary, but usually there's a per hour fee. I've seen $45 to $75. I'm sure there are cheaper and more expensive places.
