Hi SveinHa,

I did enjoy the ride - both times.  And I was glad the only thing I was risking was arm chair rump rash. 

It sure is a good thing that engine isn't capable of jumping on that compressed air tank and breaking the valve off.  Now that would be a ride.

I believe the tank is certified for about 40 bar. It used to be a start air tank for a Callesen diesel ships engine. In this configuration, we only had 6-6.5 bar. Normal start pressure for the Rap should be in the area about 12-13 bar. We used the tank as a buffer to be able to get as much air as possible into the cylinder in a couple tenths of a second.
