Hmmm, no responces on the starter..... how about this?  Does anyone monitor EGT's & CHT's on their Subs & how? I'd like a little more info than just oil pressure & coolant temp & system voltage when I'm flying.<br><br> Or we could just talk about Crazy Ivan! :-/

Water cooled engine means CHT is useless.<br><br>No way to control mixture means EGT is about useless. So what else do you want to monitor?

Re: Subaru monitoring

Are you sure about that Ron?  It doesn't seem that CHT would be useless on a water cooled engine.  Please explain.<br><br>p.s. Chris, sorry to change the subject.  How about some more flight reports?<br>

Re: Subaru monitoring

What is a CHT on a water cooled set of heads going to tell you? On the Rotax engines it can help you by letting you know the engine is up to temp - along with the water temp. but on a bigger engine like a Sub I just see no good reason to have one.

Re: Subaru monitoring

Ron I think I agree!  Thank God, Now I won't have to buy more stuff!  Todd, more reports coming!

Re: Subaru monitoring

If you got to have more wiz bang dials to stare at a good one to have is a fuel pressure indicator. The engine won't run long if the fuel pump quits.

Re: Subaru monitoring

I don't run a suby but I would consider a pressure ga on the cooling system for two reasons. 1. overheating and sudden loss of coolant. Ray

Re: Subaru monitoring

Ray, I run an idiot light for my water pressure. If I blow a hose or lose water pressure for any reason the light on the dash turns on. At least this give you more time to get organised and land before I wreck the engine.<br><br>I find that while I am training it is difficult to always keep an eye on the water temp gauge, and by the time the gauge starts to move it is usually too late.<br><br>I am considering in Firebird to have one big idiot light to cover water temp, water pressure, oil pressure etc. Then there would be a switch to find the offending area. I think that water pressure would be the best default setting.<br><br>Aussie Paul.

Re:Subaru monitoring

Eric I started by using an oil idiot light sensor. This proved it to work but would rust out eventually. When I turn on the key the light comes on if the engine has cooled a little and then goes out as the pressure builds, usually during taxi to the runway.

I now buy an adjustable pressure switch from an industrial supply place.

Re:Subaru monitoring

So Paul,

That warm fuzzy feeling you get when flying is the radiator overflow coursing down your legs...

Regards,

Nick.
