the main reason a hemi works well is because explosions are in sphere shapes a rounded combustion chamber would mean the explosion makes use of every part of the combustion chamber usualy the corners of the combustion chamber do nothing but trap gassesthat could be used it could make a slight differ...

im talking about 1s from electric cigarette lighters


dont worry i blew it up anyway now it looked the same from the one from the long nosed lighters .Anyway where can i get a bbq ignitor for without sending away for it

1 thing i have noticed with spud guns is they have flat end caps the part of the end cap that is in the chamber should be roundedlike in nascar race angines they have rounded cylinder heads

so the combustion chamber should sort of be oval

about how fast would a mini spud gun fire potatoes horizontal if anyone has a speed gun

by mini i mean something around 20cm a meter long somthing around that





any replies are apreciated

oh coz i got a spud gun bout 30cm long and i used an ordinary lignter igniter and it is rubbish are ordinary lighter igniters different

where did u get that ignitor from and is it any good
