So what would cause a motor that's timing is maxed out to stay cool then?

The most likely explanation is that the maximum timing setting on the motor is actually not very much advanced. It could be checked if someone local has one of the motor checkers (GForce, for instance) that measures the true timing of the motor. To be competitive, the actual advance should be set in the high 40s or more (degrees).

My Thunderpower has a Kv of 2190 at 40 degrees, and 3060 at 50 degrees. At high timing settings, a small change in timing will make a huge change in Kv.

What is the best front diff to use while staying TCS legal?
New to mini and trying to get my car right.
Currently using the stock gear diff, but does not seal so after putting some 2.5 million in it only lasted 2 races.

Okay so that makes a lot of sense. I would have thought that the manufactures would
Have basically set their timing marks the same. But I guess its more like having an amplifier
that goes to 11 instead of 10! (This is Spinal Tap reference)

Itemized running my TP 21.5, with the torque rotor, today in my over geared mini. Started out at 50*. It got up to maybe 130f after 6 minutes, but never really spun up all the way. Dropped timing to 40* to get a little more torque and it was a dog. Sensitive little thing.

The stock diff was not designed to hold fluids. I've stuffed them with all kinds of stuff and even earplugs squish out after a while.

Anyway, about that obscure part I'm after. I'll take dimensions, since the parts probably aren't available at any price.

What do you run?

Itemized? Frigging autocorrect. I don't even know what I meant to say now.

The overgeared car was a Xevo. My regular minis are M03 and M05. Today was the 03, stock diff, with two extra shims per side. Simulates the M05 (3Racing) gear diff very nicely.

Wait what was I going to say next????

Aren't the Shur R1 and Turnigy Trackstar re-badged/re-tweaked Reedy cans?

Personally, I have found the Mach2 to be an excellent motor. It has high rpm and a very wide powerband, which is important in a spec class with a limited gear ratio.

Speedo's make a big difference in how the motor translates that power. Not sure about being TCS legal, but setting timing and punch make a huge difference. I recently switched out a Novak Edge with an Orca V3, and the difference was night/day.

For those who are not bound by TCS, the 3racing gear diff works great. I have seen people go as far as 2.5 million. But as others run with have said, 500k is sufficient to make it work how you want it to.

For those who are TCS bound, a tight ball diff works well. One the our local fast guys runs a ball diff that virtually has no grease in it. The diff crunches when you try to turn it.

For the planetary gear diffs, i ran out of Hara putty one time and spit chewing gum into the diff to stiffen it up.

Or, I could try this...

Do you notice any leaking at all on this oil diff? I want to get one, but can not have leaking oil in my basement track.
I will be using AE's 100K. It's pretty stiff but not too stiff. TIA

Really... high rpm is what I don't have off my Sonic. It has torque, A LOT of torque, but gets pretty hot easily when timing is advanced. Bert recommended me to get a 12.3mm rotor.

It works fine on a 4WD m-chassis like my CupRacer. I thought about putting it in my 4WD truck...

We have a Turnigy Trackstar,, red can, and haven't had any issues with it at all.
We just had to figure out the timing setting because the timing bell isn't marked
All that well. But honestly, you can't beat the price!
