Turbo

Turbo is a consumable item in Fallout: New Vegas.

Characteristics
It grants +1 to turbo upon consumption. The turbo world model is a canister of jet rigged to an aerosol bottle which resembles hairspray. The effect of turbo is a brief slowdown of the surroundings (time goes at about 35% of its original speed), including everything from your enemies' movements, to projectile speeds (your own projectile speed included). However, you are not slowed down yourself - your own movement speed, and fire rate will remain standard.

You have the option of receiving the turbo recipe from Diane of the Great Khans on the first leg of the Aba Daba Honeymoon quest. The recipe requires:
 * Science skill of 50
 * 1 broc flower
 * 1 cazador poison gland
 * 1 jet
 * 1 turpentine

Its unique perk Fast Times (reward from using turbo 20 times), the challenge perk Day Tripper, the Chemist perk, and the Logan's Loophole trait can greatly increase its duration. With all of these, the total duration is about 60.8 seconds per single use, or about 30.4 seconds without the trait.

Turbo causes a brief 'bullet time' effect that dramatically slows the passing of in-game time, which in turn has many effects on the environment around the player. Turbo will not slow player collision physics, movement, or actions. Non-player characters will experience an opposite effect and suffer heavy speed penalties to the aforementioned stats for the duration of turbo, as well as object physics. However, projectile speed from guns or thrown items will be slowed for both the player and non-player characters since bullets, grenades, or thrown melee skill weapons are under the effect of game physics once shot or thrown. This same physics effect applies to manipulable objects as well such as loot-able items or objects that can be moved with collision effects.

Periodic status effects have longer delays between each tick or application of the effect and a longer over-all duration while in turbo. A poison that would normally inflict 6 damage every 3 seconds would have a longer delay between periodic applications of damage and would have a correspondingly longer duration. The duration extension of status effects also applies to non-periodic status effects such as the duration of a Stealth Boy if one were to compare its duration while in a constant period of turbo to the duration it would have outside of turbo, the Stealth Boy worn in turbo would last longer. This does not mean that activating turbo would extend status effects after its duration. The game only matches the duration of the effects and periodic timers to the slowed 'turbo clock'.

Additionally other actions such as viewing the Pip-Boy, switching on or off the Pip-Boy light, holstering or drawing a weapon will be dramatically delayed. It also affects instances where the duration of time is crucial, like when swimming underwater, defusing mines, or some quests. There should be noted that turbo has a high addiction chance and the effects are quite devastating, the user will lose 2 points on his Agility. In V.A.T.S., this drug has no noticeable effect, outside of V.A.T.S. it's extremely useful for snipers that try to run away from melee attackers to regenerate AP - since everybody except the player is slowed down, you can increase the distance between yourself and the enemies necessary for sniping (rifles usually miss in V.A.T.S. in close combat), while regenerating AP while running away.

Challenges
Fast Times: Use turbo 20 times.
 * Reward: Fast Times perk which increases the duration of the turbo effect.

Locations

 * Around three can be found at Red Rock Canyon.
 * A few can be found in Nipton Town Hall, behind a locked door a little in and to the right. The key to the door is to right just after entering, behind a counter with an armed frag mine.
 * Doctor Rotson at Hell's Motel will always carry a single bottle.
 * In Boulder City, where you first meet Jessup, a turbo can be found on the shelf, or on the floor to the left of the door, as it may have fallen down. However the only way to obtain it is to steal it, which may make the Great Khans in the area hostile.
 * They can be purchased from several vendors. These vendors include Jack and Diane at the Red Rock Drug Lab, and the bartenders at Gomorrah.
 * One can be found by the two suitcases at Black Mountain.
 * Can be found on numerous Powder Gangers in the NCR Correctional Facility.

Bugs

 * Turbo seems to have some adverse effects on the incinerator and the heavy incinerator, causing the projectiles to have up to double their normal velocity.
 * Using thrown weapons or Euclid's C-Finder while turbo is active may cause the game to crash.
 * It may also critically slow down your reload speed (as if it never worn off). The only known way of reversing this is to reload a previous save (not tested)
