This one is (literally) jet-powered:
Powered by General Electric J-79 jet engine straight out of a F4 Phantom fighter jet, the big yellow school bus, which is the largest jet vehicle, does excitingly fast 350mph. This 42,000 hp, 10-foot-high, 35-foot-long bus blasts a 75-foot flame out its exhaust...
The bus driver, who wears a seven-layer Kevlar suit while operating this vehicle, has prior experience driving a jet-powered portable toilet.

B: Not the largest jet powered vehicle.
C: Lame

Now I know why I need a Bugatti Veyron.
However, I believe that the only item on it which happens to be stock, would be the roof.
Minnesotastan has as much burn in that post as that bus. :P
I usually just throw down that "If you don't like the quality - contribute." and then drop the link for the upcoming queue.
It may be theoretically capable of doing 350, but no way it actually got clocked at 350 with the pictured design. You'd need wings/spoilers or something to provide down-draft and keep it all on the ground.
