Hotwire it, take it off a jump going 130, and you'll bottom out probably fucking the oil pan/transmission shit.

Also it's fun as hell.

^
or... not

but u could go under the car while its cold (so at night when its been off )and the oil is as thick and slow pouring. pop off the bolt cover that plugs the hole to the oil pan. and quickly jam a candle stick in to the hole so the oil doesnt come out. break off the excess candle. leaving just enuf so that it lies flush with the out side of the oil pan. when they go to start there car in the morning(or when ever) they will get about 100 feet down the road before there oil pan heats up and melts the wax causing the oil to flood out and lock up there engine

someone posted this a while back on the pyro thread

oh well my bad then.
i wasnt trying to sound like an ass anyway.

that candle thing is an awsome idea

put diesel fuel into a unleaded only tank

Your a sick demented man.
anyways

Under the hood:

If they have one, put the connectors backwards on theyre fan (if its electric), supercharger, or turbo.
will take them FOREVER to figure it out
if its a supercharger it ussually wont start, and if its a turbo it will kill the engine when it turns on.
The fan, theyll keep overheating and not have a damn clue why, cause the water wont be low or not flowing.

thin strong knife and wedge it under the heads and move it around some.
its equal to blowing a gasket

MY FAVORITE
turn the idle high as FUCK
imagine starting your car cold and all of a sudden its at 6000 rpm?

loosen any damn thing

like 1 side of the heads

loosen any belt pulleys

old dog shit on the head
starts stinking when the engine heats up

anything in the radiator
my favorites:
jello
food dye
corn starch
anything carbonated
bakers yeast
ect.

find the cable to their odometer and cut it
spin it with a power drill and duct tape for a couple minutes
someones new car now has a couple hundred miles or so

just start going ape shit on everything, breaking off spark plugs pulling out wires, turning every screw on the carberator, pulling out hoses, whatever.

draw a scary face on the bottom of the hood

Exterior:

Any damn thing in the gas tank.

get a belt sander and smooth down part of any of their tires, just a small amount, so it makes about a 4in wide flat spot. but not to far that its easy to see
They go over 30 and vibrate like hell annoying the fuck out of them

any kind of animal in the car

substance under the door handles

Its been said but candle in the oil pan drain hole is awesome.

small fireworks in the exhaust

co2 canisters in the exhaust quit a bit more destructive

prepped jb weld on any hinges

graffiti

draino or some other dilluted acid on the paint job, fades it overnight where it touches

shit load of random papers under the windshield wipers

fucked up bumper stickers

if you can get in the car-

so much shit you could do
that i dont feel like explaining
be creative

FECAL PAINT JOB
said in some other thread....

You're an idiot.

there are no wires that control a supercharger or turbo.

How are you going to turn the idle up? 90 percent of the cars aout there now are fuel injected.

I'm just gonna stop there.
