Sweet. Sounds like you had a good night.

240 is right on target for the K4.6, as long as the power is good and there's a decent smoke trail from the engine. The more you run, the less you'll have to rely on temp and more on how it feels.

I'm experimenting with a diff setup someone gave me on truggyracers (I'm a mod there). Instead of 7/15/5 or 3, they're running 5/7/2. I'm going to try this or something a little heavier this week and see if it tightens things up.
