got my Golf booked in for a power run on a rolling road tomorow,purely to see what the old girl is putting out,are there any pitfalls in doing this? ie,will they blow my bloody engine up?!!

anyone had any problems after doing a rolling road run?
my engine has high milage but has been well looked after over those miles,had a recent oil change and the water pump etc was changed recently,as have the turbo/coolant hoses to silicone parts (most of em anyway).
cheers
