* Temps are RISE ABOVE AMBIENT after 12 hrs, on our Cherokee 235 with Lyc 0-540. Aircraft was in our unheated hanger, the air inlets were plugged with foam rubber cowl plugs, the cowling was covered with a blanket which laid over the top and hung about halfway down the sides, and the sump had 9 qts of oil. The temperatures were obtained by a calibrated digital thermometer with a remote probe inserted between the top two fins on the center left cylinder, and a second probe dropped down the oil filler tube with the tip suspended at the 4.5 qt level.

Our band heater clamps around the cylinder, and does not replace any bolts. The other brand heats the head with a bolt heater replacing either a rocker cover screw or intake manifold bolt What about the other brand's claim that heating the head is best?
A big advantage of our system is that it is non-invasive. All our parts are installed "on" the engine. Nothing is installed inside the engine, and you do not need to remove any OEM parts or replace any OEM parts with our parts. For example, our competitor's system replaces the OEM intake manifold bolts or rocker cover bolts with their own heated bolts. These are simply hollowed out bolts with heating elements epoxied into the hollowed out shank. The intake manifold is held to the cylinder head with only two bolts. If a hollow bolt heater breaks, that side of the intake manifold would come loose and extra air would be sucked into that cylinder, which would lean the mixture and possibly cause engine damage and a power loss. As a general design philosophy we feel it is safer not to replace parts that were installed by the engine manufacturer, especially structural parts like bolts. |
