The episode is on bittorrent if anybody wants to watch it.
In the beginning animation, it mentions 420 horsepower and 1200 foot pounds of torque! A 4 banger can't get that ratio of power! The HP # is attainable on a heavily boosted VTEC engine but not the torque numbers. At least they got the curb weight of 2359 pounds correct (stock 2000 Civic Coupe), though they didn't account for the mods to the car or the driver so really that was an error as well.
16:30 into the episode, the scene is at the car analysis place and the guy mentions 'weld points' when talking about the front grille of the 2000 Honda Civic, how a different front grille has been put on the Civic. It's all plastic, no weld points! Just clips.
The ox ('oh ex') gecko ultralock 2-way differential. LOL.
Overall I found the episode to be enjoyable and the bit about the differential was hilarious since you can't put in a custom differential to a Civic transaxle (at least that I know of).
The script writers allowed a bit too many errors to make it a truly enjoyable episode for me.
I also found the character of the mechanical engineer enjoyable. Wish there was a computer engineer character as well but that wasn't applicable to that episode. I'm a nerd. Numb3rs is for nerds.
