Gyro Doug

Yes. Its in a Gyroplane. Subaru engines from EA81's to EJ 2.5's are relatively popular in Gyros. Especially the 2.2's & 2.5's in 2-seaters. I just don't know if I need a Oil Cooler? Thanks.

I have a 100hp version of the EA81 on a Gyroplane. The oil pump is now leaking. Here is my question as I am NO mechanic... I also have an oil cooler installed on this engine. I have 2 lines that run from the oil pump where the oil filter is installed back to the oil cooler. DO I NEED AN OIL COOLER? This was already installed when I purchased the engine/gyro. Do I need an oil cooler because I fly this engine at a higher RPM than when in a car? I take off at 5000 RPM and cruise at 4500 RPM. THOUGHTS? I have an oil temp gauge as part of my gauges. What temps are OK for this engine? Again, the 100 HP truck version of the 81. Reading this threads tells me I need to just order a new oil pump and not bother with fixing the existing leaking one. This sound about right? Thanks folks! Doug
