Help :( 8ight-T temps gone through the roof!!

[primus95]

Hi ALL,

Have had my 8ight-T for almost a year now and have had temps dialed nicely for a while now, motor hovers in the 155F range after a hard run.

I rebuild my centre diff last drive, and my front diff last night. I went up to heavier fluid to stop ballooning and now my motor temp has gone through the roof (198F).

Castle 2200Kv - 14/48 gearing on 4s.
Diff fluid = 30/50/10

I can't feel any binding in the diff's. Centre diff was completely rebuilt last run with fresh gears.

What could have caused such a jump in motor temps?
