Ya, my son was there. No matter how many of my friends tell him the amazing things I've done since I was 5 years old, he doesn't believe them because he didn't see it. Maybe now he will believe me.
Wish there was these kind of competitions over the pond. There is a race here, but I'm not sure what the rules is regarding electric drive - maybe there is a hole in the rules
If anyone is interested, here is a pic of the inside of my motor after I coated the windings with VHT high temp epoxy spray, and siliconed in the temp sensor, and showing upgraded 10awg phase wires.
Inspiring to see a t-shirt clad regular guy with passion and heart beat lycra clad riders on expensive boutique bikes for those that can afford a well-designed, but WAY over priced bike. Inspiring...
Nice work! Congrats on your win. It was nice to chat with you at the top, I hope you enjoyed your ride down. Did you get a chance to check out Bishop Castle while you were in CO?
Damn all,way to go Adam, you beat them with a DF and a 9C motor. You're the first place bike at Pike's Peak this year. Trikes are in their own class, bikes can't corner or brake as well as a trike. You have to be in the record books man. Good on ya!

Craig,
I did check it out online. Quite the place. Unfortunately, we had to decide between the Cog Rail, and the castle. I was outvoted. So, I summited Pikes twice in one day! It was great talking with you guys at the top too. All great, classy fellows! I'm looking forward to your videos. I haven't seen a complete ride video go on the web yet.
Winter teardown:
Controller:
Soldered the cap back on after hearing it rattle inside the controller. Not too bad.
Siliconed each cap for vibration resistance.
Snugged the fet screws. They were ALL loose!
Spread more thermal compound on backside of aluminum fet bar.
Installed 12v cooling fan in end cap of controller.
I guess I'll find out if my surgery worked when I hook everything back up.
Motor:
Installed new Japanese bearings with thin layer of silicone sealant
Re-sealed interior axle/wire slot with silicone sealant.
Tapped hole in side cover for one way pressure valve like these...

Hopefully this will work a bit better than the "tiny hole" method. I will have to stop and bleed the air once I reach maximum temperature. Hopefully the motor will be in a vacuum state after cooling, which should help avoid leaking fluid.
We'll see if it works.
Plan on getting no load currents for motor with:
0 ml:
100ml:
150ml:
200ml:
250ml:
300ml:
350ml:
400ml:

1200ml:
I measured the total full capacity of the motor at 1300ml using water. So I suppose I could use up to 1200ml, leaving a little extra for heat expansion etc... I calculated the thermal expansion of atf3 at 0.3% per degree C, so it really doesn't expand too much even with a delta T of 100C. Its the hot air I worry about. If I don't bleed that valve properly, or didn't seal the motor properly, I may have created a pressurized, hot oil filled, spinning electric device that I'm riding at 40mph. What could happen?
Itchy, that would be great data about oil cooling. Might I suggest recording the no load rpm with each measurement. Full might be interesting info, but where would that be useful other than running submerged?
Also, thx for mentioning loose FET bolts. That is something I have never even checked. How tight are those supposed to be?

Thanks guys..
John, I really don't know for sure how tight they need to be. I posted about this in my other thread... http://endless-sphere.com/forums/viewtopic.php?f=2&t=44994
and it is mentioned just to have them not too tight, as it may actually pull the fet back off the spreader bar (makes sense when I look at the fets). So I just "snugged" them all.
I will also record the wheel speed (and indirectly the rpm) at the same voltage for each data point. I meant to do this the first time I setup for oil cooling, but I was too eager to put in the oil and forgot.
