i maxed out everybody's pod racer (except the ones i didn't get, mawhonic for example and the others because i didn't wanna trash my good parts and use the pods i already got in the free play and 2-player), all you gotta do is play the semi-pro first, and just buy from the junkyard and make sure you don't get into alot of wrecks (it's better to crash and have a clean green podracer when you finish, i got ben quadrinaros by doing a last second crash into the finish line-not a good site even though i got him) first of all try to buy the best parts in watto's junkyard, even if they're completely run down-that's why you've bot pit droids-to repair them later in the game. first try to upgrade your traction, turning, repair, and cooling, (or get the mag 6 injector as soon as you see it, it'll max out your top speed) and then start looking for good parts to upgrade your top speed and accelleration. you wanna look for the Turbo thing and the Mag 6 injector. And for a good tractiojn, a stabilizer.
I hope i helped someone out.
