Hi guys, I was just thinking ... as you do! What is a rolling road made up of parts wise and has anyone succesfully made a DIY rolling road? Initially I guess its just getting the rollers and getting them correctly aligned or balanced. The part that sits on the side of the rollers to measure the output is only needed for power runs im guessing?

Is there a company that just sells the rollers? I could make do with this if the cost was alot cheaper. If anyone has any information on this it would be much appreciated.

Can I temporarily get round the problem with buying an inductive clamp and software to measure and record the sound as a WAV file then work out the stats? Im not sure how relaible these are.

My main purpose is basically to have a "rolling road" not one that measures any output as I could take it to another place later down the line if I wanted to boast about my figures. I just want somewhere to tune off the road.

Please let me know if theres anything im missing here, surely someones gotta have thought of this before

 

I think if you're looking for something that will allow you to tune "off the road", one of your best options would be something from Dynapack. However, it's certainly not going to be inexpensive.

 

The guys at UC Davis made a dyno to test their formula SAE engine. They got a brake from a heavy duty truck, a metal beam, and a bathroom scale. They made it so the metal beam presses on the bathroom scale when you apply the brake. It's just like the original Dyno, the 'prony brake'
