Destroying an engine

This might sound odd at first, but I was wondering what the best way (the most fun way) of destroying an engine would be.

I just recently ran in a demo derby and the body if the car is not worth saving anymore (its been through four races). The engine, however, still runs. The whole vehicle is going to the scrap yard no matter what, but before it goes, I wanted to have some fun trying to destroy the whole thing. So if anyone has any crazy ideas in mind, I would like to hear them. I have always wanted to destroy an engine under its own power, and now I have the chance.

Oh, and by the way, the engine is a GM 305 c.i. that is in a Cadillac.

You should be ashamed of yourself. I don't think I could ever do what you propose. I don't like killing anything....well almost anything.

That being said, preventing an engine from cooling itself will indeed kill it. Hell, remove the oil, too, if you want to kill it quicker. Oh yea, peg the throttle, too. Add a shot of NOS, if you feel inclined.

i think preventing the cooling will just seize it. I'd pump it full of NOS till something goes booom. Video tape it

Peg it WOT, add some n20

I'm sure you can find a shop somewhere that'd be happy to rent a bottle to you, if you give them a copy of the vid when ur done.


Wear safety glasses too, that's be something to say if u cut ur eye or something watching an engine blow up

Draining the oil works.

Remove the oil, remove the coolant, and put a brick on the gas pedal. You could also attach a garden hose to the intake and from a safe distance turn the water on while that engine is wound up.

Sell the engine and put some money in your pocket. Other than that, draining the oil will do the trick but without any fanfare.

Get it warm first, with the gas tank almost empty.

Then, fill it up with Kerosene. Drive it around until it pings itself to death.

We tried killing a '68 Mustang straight six by putting a brick on the gas pedal in neutral. It just screamed along until the gas tank ran out, not too exciting. In college, we put a Mazda rotary on the engine dyno and ran it at full power for a couple of days, no damage. We even poured antifreeze down the carb, but not enough to drown it, still no damage.

The most catestrophic way I could think of is to hydro-lock it at WOT. The garden hose thing from far away sounds like it would do the trick. Just stand well enough away from it, and have some fire estinguishers handy.

The surefire way to spectacular results is to pull the engine apart and take a hacksaw to the connecting rods (don't cut all the way through). Then put it back together, don't put any oil in it, and run it at WOT until she blows. Though this is probably more work than it's worth unless your doing an engine blow raffle or something along those lines.

Just draining the oil or water usually just seizes the engine. I like the idea of hydro-locking it at WOT, though that may just bend some rods and not make it go boom. If you're hell bent on blowing it, give it a shot.

So what you're saying is none of those engines made enough power to hurt themselves.


Brick on the accelerator.

Massive advance on the distributor

Rig up a REMOTE system to shoot starting fluid (ether) into the engine

Sand down the carb (kinda anticlimatic I think)

Full shot of nitrous without adding extra fuel (massive lean condition)

Mothballs in the gas tank? (I think that's a myth)

Rewire the half the plugs to fire on the intake stroke.

Fill the crankcase with gasoline.

Dynamite? Nuclear weapons?

WARNING!!!!
If you plan on doing any of these, figure out how not to be next to the car when it goes. Have fire suppresion / safety equipment at hand.

These are all great ideas. I like them all, but I am really liking the hyro-locking idea the most. It seems like it would do the most damage.

And for the record, the engine is not worth trying to sell or rebuild. It's way past that stage.

Keep the ideas coming. I'm hoping to do this within the next few days.
