Robitronic Dyno
 

This is the daddy of dyno`s.

I used this a fair bit whilst racing on road, it can either be used to link up to a PC and provide graphs for torque, rpm, Power(w), current draw and time etc. Or used a stand alone unit. and you can scroll through the screen.

It is also a charger as well and fully adjustable.

This cost me about £550 a few years back now. I am open to offers :)
