<div style="font-size:10pt;font-family:arial,helvetica,sans-serif;color:black;"><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">Piston ring flutter is a hard to detect phenomenon that will allow a lot of pressure loss into the crankcase.</div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;"><br></div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">Rings that are too thin will tend to flutter due to less spring pressure. The higher the piston speeds as in the wet sleeve TR engine, the more likely flutter is to occur. </div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;"><br></div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">I'm not sure about the Spitfire engine (too lazy to do the math before coffee) but if you choose thin rings such as those used in the Total Seal set up, the more likely you are to get flutter. The Total Seal solution uses two half-height rings with the gap oriented 180 degrees from each other. IMHO this is asking for flutter.</div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;"><br></div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:black;">Having said that, when they work they work well.
