Lysergic Acid Diethylamide. A hallucenogenic drug
that is really in class by itself. First synthesized in the
late 30's and investigated by the U.S. Army in the 50's
as a possible mind control agent, it found great popularity
with the 60's hippies and celebrities. Still around today
and relatively cheap on the street.

LSD ("Acid"), taken in a sufficient dose, is mood altering
and can produce gross perceptual and sensory distortion.
More importantly, it seems to unlock the barriers between
the subconcious and concious mind. One researcher
compared it to producing an artificial psychotic break,
almost like seeing what it's like to be schizophrenic.

Most experienced users agree that the mood of the user
and the company or surroundings will cause a good or
bad experience. The drug's use can also be compared
to playing Russian Roulette. Five fun trips and The
Worst Experience Of Your Life. It also can cause chromo-
some damage and trigger real mental illness. Some users
report seeing after-effects years after they have stopped.

Fun fact: Vincent Price can be seen reading up on using
LSD to help frighten a victim to death in the 50's
schlock horror flick "The Tingler"...
Are the high you get and/or the insights you think you're
getting on LSD worth the risk? Depends on who you ask,
like say the late Tim Leary or the late Syd Barrett.

A limited slip differential. Normally cars have an open differential or "peg leg" which allows the outside wheel to turn more when cornering. The downside of this is the car loses traction easily due to all of the power being transferred to the wheel with the least grip, causing a one wheel spin.

A LSD limits the slip of the wheel using clutches which lock the two wheels together when it reaches enough slippage.

This allows for increased traction and speed in drag races, increased control in drifting and increased handling in grip racing.

Known as posi-trac to muscle car guys.

Is not a "locker" which locks the rear wheels together temporarily for drag racing only.
"I just installed an LSD on my 240sx to make my drifting smoother"

"My Mustang has an LSD to make it launch with less wheelspin."

"My Porsche came from the factory with an LSD, this makes me able to accelerate out of turns easier."

"OS Giken makes some high quality LSDs"

The best way to describe it is that it is the dying hallucination, it's the last shit you see while your dying. Nothing will ever enlighten you more than 500 micrograms of acid. EVER!

except for maybe 1000 micrograms or ten hits. That's like a three day trip and nobody want's to trip for three days, that's just wild. Also, much of the acid you find today is 95% pure, the rest is adulterated mdma and nicotine, scopolamine, and atropine, etc. This is why acid has gotten weaker over the years and a hit that used to cost $5 in 1987 is now $15 in 2010. True Story.
LSD is the most powerful substance on the face of the planet. It is an experience, not a drug!
