i need understand something :

when jackssmirkingrevenge say ''a 2x mix would be 8% butane pressurised to 15 psi''

is it mine 8% of the chamber volume ?

thanks...

i like training my english so why i am here

perfect MR ramses, thanks

thank you rames for this comment, i know what i will do i will show result of my hybrid !!

finaly its maeby better with a pop-off, la nuit me portera conseil car je vais me coucher!

thank you for the french help, i just would like to know what systeme use the cobra, or larda, do you know ? burst disk or piston

if piston what about ? how is work ?

thank you POLAND_SPUD

salut CpTn_lAw, je suis d acord avec la pop-off mais a chaque tire ya une projection d air qui sert a rien alors que ce que j essaye de trouver c'est une solution pour "recycler l air'' et c'est aussi reglabe celon les mix en fonction de la pression qu'on met a l arriere du piston. non ? lol j ai pe...

yes i think about non-return valve to vent the volume of air in 'Chamber A' to another chamber 'B'.
After shot , can reinject this volume in chamber 'A', its quick to set up another shot[img]C:\Documents%20and%20Settings\mam\My%20Documents\My%20Pictures\untitled.JPG[img][/img]

how to do for measure 20% butane inside chamber if my butane reserve is directly conect to the chamber ?

for example my chamber have 1 liter capacity...

ok thank you for your comment i thinking about this idea !

i need more comment some one else ??
you read but you don't poste, come on every body !!! loool

all in the subject title :
what do you think about this piston systeme ?

i need your comments !

i mine if you want the gaz reserve directly conect to the chamber, you can't do this method !
