which doesn't really even apply to spudguns anyway (since gasoline reacts very differently when compressed than propane or MAPP gas do) propane motors exist too last time i checked Commonly everybody say ddt will happen at 5x or 6x mix... Well im shooting my cannon at 7.5 x.... did it burst nope ! ...

I'm baaaaaaaaaaaaack pyro: the shockwave would only act on the walls of the cylinder and the cylinder itself won't burst because that would require enough force to blast open the engine block, which CAN NOT be generated because the detonation moves the piston and releases the excess gas at the end ...

You're not factoring in things like the repeated stress of the steel pipe (which is not intended for hot pressurized gases anyway) expanding and contracting over and over, dealing with the shock of detonation repeatedly, etc... as and diesel motors factor in repeated stresses the steel pipe... expa...

ALL THE INFORMATION BELOW CAME FROM WIKIPEDIA AND IS 100% FACT Due to pinging (DETONATION), the CR in a gasoline/petrol powered engine will usually not be much higher than 10:1, although some production automotive engines built for high-performance from 1955-1972 had compression ratios as high as 12...

the chamber fan and wires are fine but the pvc union is burnt brown on the inside
i will post a picture soon

i dont smoke or drink so i dont know about cuban cigars

i spent 11$ on a can of MPS gas and when i hooked it up to my gun it would clog the adapter up and i cant get pressure into my meter

did i get a shitty can of MPS or does MPS suck

i got a idea that i think would be easier

why not make a chamber fan
gas motors use liquid fuel(gas) and propane no problem
and there basicaly a automatic hybrid
MIX YOUR FUEL PROPERLY AND IT WILL BURN

tubes of silicone or anthing that fits in a smaller caulking gun will fit in 2"ABS or 2" PVC

its awesome when you shoot a wall and it explodes

take a look at my idea its called hybrid or pneumatic self venting idea on the first page of theroies

there is garbage cans that will stay together with TEN pounds of C4 blown up in them

also detonation is not dangerous if your hiding behind somthing


soliders use gernades all the time without blowing themselves up

this is my idea ...
i didnt make this picture just edited it

do NOT buy lasco threaded fittings they are moulded that means they are not threaded with a tap or die they leak

draino and tin foil make lots of hydrogen
