Work assigned me some camera duty

[buckbuck]

And I took advantage of it. Ran down the river at 10,000 rpm and opened the engine bay to take some pictures.

I have wanted to take my works FLIR camera out in my boat too. I'd love to see what the supercharger looks like and cooling system after some runs.

I like looking at thermographic images. My wife has a Flir thermography camera as part of her Equine business. I have always liked this one. It shows how sensitive these "cameras" are. Note the hand print where the handler had just touched the horse and screwed up the image.

229F was the highest I found. I am mandating with the kids they must run 6-7000 rpm for a few minutes after running WOT.

Very nice. What was the outside air temp?

 

[Gym]

Very cool, err hot @buckbuck. Was the 229 temp after wot going to idle without an intermittent cool down run?

Very interesting, but open to misinterpretation due to the emissivity of the various parts.
What does that mean?
It means that the Infrared reading needs to be factored by the emmissivity of the surface.
For example the shiny chromed surfaces are not good at emitting heat, but dull black surfaces are.
I have posted the table below and you multiply by the coefficient to get close to the temperature.
Also you have to be careful about shiny objects as you might be reading a reflection of the sun (very hot) or the clear sky (very cold). Either way there are a lot of possible variations possible and as a certified IR technician I thought I would be a little bit of a picky reader.
When you see a big difference in parts the main real difference might be the emissivity of the surface.

@Gym Yes 10,000 rpm and then just shut down. I was attempting to simulate a worst case event. Air temp was in the mid 80's.

This should be an FAQ item. As they say, thermography picture is worth a thousand words, lol (and points the importance of cooling these beasts off - with raw water - before putting them away). @buckbuck this could also make a fine exhibit in your "understanding Yamaha cooling system" thread already there.
Very cool! Pun intended.
