I'm rounding slightly. If I use my tach that's what it looks like, but it's hard to get a really precise reading with the resolution of the tach needle. You need a really flat, level surface and then get in a steady state with zero acceleration or deceleration and then try to get an exact reading from the tach. Maybe it's me but it's not as easy as it seems to get the resolution down to the tens of MPH. When I use an online RPM calculator I get 509. So it's in that ballpark.

I'm sure you've used them, this is the one I use:
