From what Ive seen 5700kv seems to get hot in SC trucks I run 4600 geared 17/88 and I get temps around 140-150. I know your probally on the throttle a lot more than me though. And get some airflow through that big body. A couple of holes in the windshield and cutout the back to cut down down on drag.

That seems hot for a 4600. Stock should be set to 10 degrees.(It was on my MMP) I ran 15 degrees of timing on a 5700/2s in a 1/10th truck on the oval and temps we're in the 150 range.(16/90) I had punch control set to 10% though.

Faze,
168 is not too hot for a CC motor. They tolerate higher temps. Call CC up on Monday to verify this.
A CC 4600 motor should kick *ss on a 17.5. An equivalent sensored motor would be a 10.5 or so.
2s is noticably slower than 3s. A vehicle that does 30mph on 2s should do low to mid 40s with the same gearing on 3s, and out accelerate the 2s along the way.
If you are mostly intetested in top speed, what you have your punch control set at wont matter much, but don't set ot too high. Try 20-30° of timing advance and that 4600 should do well on 2s. Shoot for 180°F, but call Castle on Monday to verify.

I had some back luck with Novaks so I didnt want push above 160. But I dont need all out speed the race isnt won on the straight.

... I found out tonight how hot they can get before they blow.... 
I was out practicing, put the 3s lipo in with 15/88, ran for awhile, saw smoke start coming outta the car, temped the motor at 310 degrees.... Shes done. So I went a picked up a novak ballistic 13.5, threw a 27t pinion on right before the heat and just went balls out. Pinion came off 3 laps in, DNF
Second heat rolls around im on practice laps, my wheel flies off because the wheel bearing somehow shattered and the axle slid through the knuckle....
They decided not to run 3 heats, so onto the feature... Get the issue fixed just in time, go out and got third. My first time ever racing, so im pretty happy. The guys pulled away on the straights but I could beat them through the turns.
Expensive, but fun day.

3s and 2s is very different, and when you change the surface from like concrete or asphault to dirt, the speed will change. I dont know what kind of surface your track is but this could be the reason and your probally not getting enough grip from your tires. Just some options.
Battery could be a issuse or bearing.

310 is crazy hot, sound like a good day in this great hobby. Just watch those novak motors they dont to be pushed over 160from what ive seen.

Weird part is, the wheel was spinning perfect all day long... Even right up till I put it on the track. And I ran the novak for a 5 minute feature and It didnt even hit 115... I could hold the motor it wasnt hot at all thank God. Its too slow though so im going to either an 6.5 or 8.5 soon.

Hey guys, I have a question..... I run a castle MMP with a 4600kv motor in my blitz.... Well im used to bashing with a 3s lipo and the thing flies... I went to the track yesterday, and I was using a 2s lipo (5000 mah) and the truck seemed really slow, like almost stock speed kinda slow... Is that normal or is something wrong? WHatsup with it?
