I finished the swirl pot yesterday.   All that remains for the cooling
system is the overflow tank which I think I will make out of welded
aluminum.  Is there any problem with having it fill and empty from the
bottom?    Jerry

I use the original Mazda system from the RX-2 on the race car. The overflow tank has the pressure regulating cap. My swirl pot has a filler cap to seal it but no guts in the cap to regulate pressure. The overflow bottle acts as an accumulator. The outlet of the overflow bottle could exit th cowl in front of the pilots side windscreen. This would allert you to a problem.
