I'm down to about 4#'s and some change and thinking about getting it filled. I subtracted 1 pound of the total weight for the pressure switch,brass fitting, and pressure guage. I just wanted to see if anyone does it differently or has a better way.

 

I would refill when it gets to 2 lbs left

 

Thanks for the help.

 

I have to fill mine after every two run's Every time I try to get three out of one it starts to breakup and fall off the before the traps as pressure drops under 900 from 1050.

 

yeah, but we all don't spray as big of a shot as you.

 

LOL! Yeah I was wondering about that too.

 

I got 3 runs with 150hp jets, and 1 100hp jet run in the 1/4 and still have a bit left. I'll weigh the bottle when I get home from work and post how much exactly is left!

 

Thanks

 

if i know im going out racing i like to get it topped off, even if it is 2 or 3 lbs. ask harris speed - im there all of the time for like 3 lbs or something stupid like that. it is on my way home from work though so no big deal..

i try to NOT go out intending to use the spray unless i have a full bottle or MAYBE one run on the bottle. how much does it suck when somebody wants to re-run or you spun or whatever, and you run it and it runs out mid-race (happened to me a bunch of times). f-that, keep that **** filled.

 

Same here.....I would fill it every two runs or so. I would hate to need it and not have it.

 

dam 10#ers are always empty

 

THIS is what I am using.

After two pass's I might have 4Lbs left but it is not enough to cover the pressure drop on the next pass

This scale takes four 'c' battery's and is a huge help at the track in between pass's

 

Just keep it filled up as much as possible, the more you have the higher you psi will be, which is always a plus

 

Thanks, very useful/ good info.

 

I'll do seven passes, and get it filled. Seems to work pretty good for my setup.

 

According to what I have read, you should refill when you have ~30% capacity left.
