Mr. Crash: Crash Team Racing – Throwing TNTs in the air like the bosses (Gameshark Code)

Makes the TNT fly onto your head when you put it down, even if you are moving, as if you had driven into it:
800ACD28 000C

Makes the TNT go immediately on your head when you collide with it, without first flying into the air:
800ACFF4 0012

Makes the TNT fly off your head as soon as it touches your head:
800AD590 0003

The three of these together will replicate the Komodo Joe/Oxide effect.
