Can you comment on this

"from the looks of the pics the rolling road you went to was the older type where the cars wheels sit inbetween 2 rollers. the modern and most accurate rolling roads have a set up where your car sits on top of a single roller (looks scary when u see a car doing 100+ mhp perched on top of a single roller! )

the old style rollers are not accurate its a well know fact i m afraid variable like how hard the car is strapped down etc can alter the readings dramtically.

if u want a true and probably disapointing reading you need to go to one of the modern rollers i think there is only 3 in the country and they are all used by prodrive,noble,cosworth etc because its is well know in the trade that they are the only ones that give 'true' readings"
