Pod Racer Walkthrough: 6: Fire Mountain
This track has a ton of curves, and a huge jump. There are even little auto-jumps in the lava that are sort of neat. When you go down into the lava area, don't panic if you end up in the lava - just get back out before your engines catch on fire.
Mostly this is a reverse course of the nasty water-swamp course, complete with pillars. Drive carefully and you should win this one without much trouble.
