use some darn time on your topic.

some specs and may some pics?

propellant would be propane tho.

if it is a steel gun you can use hydrogen if you are not scared of DDT

Propane meter for a proper C:B ratio.
Chamber fan for a better mix in the chamber.

just hitting the basics first.

Find a post by D_Hall on this site, and use his program (DDGT? HDGT?something like that... It will tell you exactly how to tweak your gun to maximize performance.

We can't really help you to much more without specifics on your gun. A big chamber and longer barrel always does wonders. WHen in doubt make it bigger.

And you may want to title posts like this better. "we want to get HIGHER" has a much less accepted interpretation, and its rather odd daxspudder posted here with Bob Marley quotes in his sig....I find an odd coincidence here.

Along with the good old scaling up plan you can also increase the fuel/air pressure if your device is suitable for hybrid operation.


Now I'm off with my spudgun to see how high I can get :D

^^I notice odd things like that for some reason. Thumbs up for your military service and pro take down of oppressive governments by the way.

Hmmm... last time I tried to see how high I could get
with my "spudgun" (Note quotation marks), the cops showed up.
