30th September 2006 Rolling Road Day

Dyno's usually only go to 90 - 95% of the rev limiter to avoid engine damage.
Max power and max torque come in before there anyway so in the eyes of the rolling road operator there is no need.

Not sure why it would damage the engine any more than on the open road?

Cooling issues maybe? Your car will possibly run hotter on the RR due to the fact that normal air cooling is substituted by a big fan pointed just at your radiator.

I worked briefly at a RR centre many moons ago, saw a few engines let go on the rollers. But hopefully the technology has moved on from then.


The revs on the machine I saw back then were gained as Markc said, with a sensor wire coming from a plug lead and entry of the number of cylinders.
