I'm trying to work out why Star Performance Rolling Road up in Scotland apparently gives lower horsepower readings than PE's

Could be that all our cars are slower up here but I hope not !

Does the PE RR increase RPM at a set rate ? and if so, what rate ?
ie how long does the power run take ?

I recall that a standard acceleration rate for Dyno testing was 300 rpm/sec but that was a bench dyno, not sure if same applies to rollers

thanks

CC put this in Drivetrain and you might get some decents answers

I'm no expert on this, but I think its just down to variations between the machines. The one at Powerstation reads lower than PE too. No surprises that everyone goes to PE!!! I guess if everyone goes to the same place it is a wee bit easier to compare figs, even tho' they will still be influenced by the conditions on the day.

I think Star and Powerstation have the same set-up and seem to give fairly similar results.

Power Engineering are having their rollers refurbished very soon and i think they will be more acurate after that!!!

Well the strange thing is that standard cars, especially Evos, give very similar readings between PE and PS - it's just the tuned cars that read differently!
