Bottle pressure

[Meat Drapes]

So as you can see in my sig I sprayed the car. I enjoyed it for the most part.
With that being said what did I leave on the table by only allowing my bottle to reach 700 psi ? I brought a torch but just didnt have it in me to really let a open flame touch my bottle for any length of time to heat it up.

if you have electricity use a hair dryer.... it will hit noticeably harder with 950-1050 psi....

925-950 PSI is the standard - anything higher and you loose pressure during the run
anything low,like your 700PSI and you run real rich and risk blowin your engine up big time
I suggest you get some sort of bottle heater ,they have many versions out in the market place
to keep your bottle temps at optimum

the nitrous express bottle heaters set at 1050psi... but nos recomends 950...

depending on weather and time in the lanes most guys put the bottles in
warmer than 950.......and purge off the excess pressure after a burn out

My son runs two stages on his car. We use a 5 gallon steel pail with water in it. Insert bottle and heat pail with propane frost torch. Takes about 2 minutes. Install bottle and purge after burnout. He also runs a bottle heater to maintain pressure while waiting in staging. Lee

tough to say, depends on the n/a tune and if you were running the prescribed jets from nos. you may even get some surging. i've experienced that when the bottle was almost empty but i don't know if it would happen full at 700. either way i wouldn't suggest running it at that pressure.

from the mph, looks like you got about 70hp from that hit. not to far off.

Interesting replies. The next time I go to the track I will be using a 150 hit. I will be running the pills as suggested by NOS. Unless a better suggesting comes from this thread.
I have heard to run the pills 'squared'. And while I know what this means I dont think I have the right ones to do it. Ill also make sure I have the right pressure.
I just want to hit a 10.9x ... badly.

Your on the right track........Square jetting is where I would start with an NOS plate kit
usually with 6PSI of fuel pressure flowed though a .073 jet.....NOS tuning charts are really not
very AF Ratio friendly .......

Getting the tune up right is what N20 is all about,if it were easy everyone would be fast....or running a turbo LOL

bottle needs to be 950 or as close to possible at launch. think about this. you turn it on and fill the line, purge line, then prge through engine. every time you will lose pressure. build a water tank and get temp close enough to make bottle about 1050 to 1100 inn the pits, maintain with blanket/ sweatpant legs work well for bottle socks. perform all the above listed puges and such, before you stage bump your purge to get pressure where you need it. will post a description of how to build a water tank.
