I started a thread about this a while ago, and some 'expert' said that max psi out of a pump is more about strength, rather that the structure of the pump....RAH ME!!!
I wonder if the rating is different for the different size pumps - mine is the shortest HPX you can get (Size 1) and I know the box is generic for all 4 sizes (I kept my box too, but I can't find it at the moment). So maybe the website reflects what the shortest one can do and if you have the Size 4, then you can get 160psi. I've gotta say there is no way on this planet I could even begin to get near 100psi in 20seconds - 20 minutes more like.
And maybe you should change you name to 531Arnie.
