In-car spud cannon

**Aboliton** · 03-23-2009, 02:13 AM

Hello all, so my plan is to mount two potato cannons in a free area where my fog lights would go, as shown in the photo.

For my ignition system I'm using ignition coils and spark plugs so thats all rather easy.

I've run into a problem however, with supplying fuel to the chamber. My original plan was to use a solenoid to control the flow of air from a butane/propane canister, but after 4 hours of looking I couldn't find appropriate parts. The next plan was to use a solenoid to press open deodrant can for a predetermined amount, that however isnt working well.

Does anyone have any suggestions for another method that isnt too expensive or complicated, it would be much appreciated.

you can't be serious???

Well anyways, since you have gas in your car already, why not a fuel injector of your gas line?

Not sure if I would assist you in this.. it might be my rear beeing hit by two potatos

But.. You could go for a CO2 spud...
There's ALOT of spud reading on the net.. just google it

Nice.

I'm using metered propane w/two manual valves.. this may work with auto valves.. basically so one lets the gas into a pipe that measures out a certain amount (you only want a certain ratio, otherwise no boom) and once that closes the other allows gas into the chamber. I use a bbq ignitor with a 12v battery.

Honestly you'll be better off using compressed air or CO2. Less likely to catch something on fire in case of an accident.

Also, keep in mind that a good chamber - barrel ratio is key to efficiency

I want to mount one to my 4wheeler though... a bit more likely to get use
