i was just searching through photos of the Detroit comp on photobucket and found this,

Yeah, that's a dyno demo we did for a presentation night last week. Pretty sure i stopped around 11,500 rpm or so. I'm the guy with the messy hair sitting at the controls, Jess is the woman sitting to my left. We're the engine group leaders this year.

Btw, if you're wondering, that bit near the start where the engine revs up rather than smoothly ramping is due to clutch slip. The clutch in that engine is a bit fried at the moment. The engine revs up until it reaches a point in the torque curve where the clutch can handle the torque and stays there until the dyno catches up to it. I believe it made 98 Nm before slipping.

Check your PM btw.

That looks a hell of a lot safer than our setup. When I go to the shop later today to grab my camera battery charger I'll put some pictures of our setup up. Its stupid.

Yeah, the guys back in first year (2001) did a pretty good job on the setup. The dyno itself was actually a donation to the uni to clear a debt and we ended up with it. Or something like that.

I should mention that the test cell itself is actually a converted shipping container, so it's all steel. The window is like 20 mm thick.

We actually brought this thing with us to Detroit..

Yup, you sit in front of it while you tune (used to be worse believe it or not). Yes, its just chillin in the back of the senior design lab at 3 am. Yup, there's two mufflers jammed inside each other, and oh yes.. that is a cardboard tube on the last one that goes to the outdoors.

As you can imagine, the cardboard tube eventually ignited. Not from the heat though, we could actually do a fair amount of tuning before it would start to smolder. But then when you'd kill the engine you'd get a nice flaming backfire which ignited the interior of the tube.
