Turbo

TMNF Turbo from above

Turbo (booster) is a special block that applies an acceleration multiplier while driving on it. In TMUF, there are three types of turbos, which correspond to 3 different Material IDs:

• Turbo (normal turbo, 100% boost)
• Turbo2 (red turbo, 200% boost)
• Turbo roulette (random turbo, 100 to 200%)

Turbo Roulette

They work on a fixed cycle, and are thus deterministic. A cycle is exactly 1 seconds long, divided as such:

• 4/7 gives 100% boost (tick 0-57)
• 2/7 gives 150% boost (tick 58-85)
• 1/7 gives 200% boost (tick 86-99)

Turbo Roulette Variations

100% Turbo	150% Turbo	200% Turbo
Tick 0 to 57	Tick 58 to 85	Tick 86 to 99

Because they can appear random for the players, Turbo Roulette is a pretty despised block, that has never been used in any competitive track. Still there are some start strategies that use the fixed pattern of this block to get the 200% boost. The most notable is when a Turbo Roulette is placed right after the start block: going straight reaches the booster at 1.58s, giving the 150% booster, but intentionally going on the side right from the starts allows players to consistently lose around .3s, getting the 200% boost.

Other strategies exploiting this pattern include going on the side of the boosters to only catch the 200% boost, as explained in this video by Igntul. This trick is known as Heftrick.
