Found this in my parts , any info ?
oh no that nasa oil cooler! :dawg:
its a farkle from the 70s or 80s. it was hotly debated at one point, neat peice of 'old' tech that really didnt do anything, but looked cool and or interesting.
yes, it was claimed to be designed by a nasa engineer.
Suppose the air flow cooled the rod to the oil..never seen one. It's available..it was on a bike I just picked up.
I'll take it off your hands for sh%%s and giggles.
The legendary "NASA" oil cooler. Never seen one out in the wild. There were some great board discussions about these back in the day.

I'm sure they cool, but how much (which it is very little) and whether it was ever needed are different topics. It does look whizzy in a sci fi kind of way. I like it.
In one of those old threads someone posted link to a BMW foroum, seemed to be very popular there.
It fits the BWM style, and lack of performance... Their modern sportbikes obviously excluded.
Reminds me when these beauties came out, talk about debate...
Weird old posts still there after recent crash. https://www.2strokeworld.net/forum/index.php?topic=1491.msg12192#msg12192
99% of the database was untouched. :whistle: yup, thats it.
It looks like a convective cooler. Plain heat sinks have been around for a long time and wouldn't be attributed to NASA.
Usually real convective coolers would have a fluid inside to circulate heat to the finned exchanger. Some are liquid metal filled with something like a gallium and bismuth alloy. Legit cooler tech like this is used in modern PC's (especially laptops), turbine fan blades for jet engines, sodium filled valves on 4-stroke engines, and satellites to both warm and cool.
Probably this thing is actually solid aluminum which would still work... How effective it would be, and what benefit to a 2-stroke motorcycle is a matter of debate.

the nasa thing was the guy that originally sold it supposedly claimed to work at NASA. IMHO, there isn't enough surface area on the small end of the dipstick touching the oil to cool anything in any measurable/meaningful way. IMHO, it would be more effective to mill ribs in the sidecover to increase surface area. even then, still wouldnt do shit. but would probably do a scoch more nothing than this.
:love: "a scoch more nothing"! Can I use that??

You guys hog all the cool lines.
I think, and Mark will correct me if I'm wrong, that it's public domain and anyone can use it :whoop:
use it :toot:
