lol...problem with more than 10 pounds in a 10 pound bottle is pressure drop, no good way to keep the pressure up during a run, i used to put 13 in for the track when i go sandbaggin and use the n20 first half of the track, but if im going out to run full out the car noses over on the big end because it fattens up...

but id like some info on this...what does it cost you to fill the big bottle...does the big one have a gauge (you said not to over heat it) i think a cheap deep freezer would be a good investment to freeze the little bottle, normally can get almost all of it in there once the 10 pound is frozen...and can you not buy the bog one? you said you were renting it

 

It will vary by your location. I pay $110.00 for a tank exchange. (65lbs) If I was to have my bottle filled it's $4.00-.50 a lbs. Plus I have to drive atleast 40 min away from my house. I do not have a gauge on the Mother tank. I do have one on the 10 lbs tanks. I have a spare refigarator that I can do two bottles at a time.

I didn't check on price on the main tank. I don't think I can buy one where they exchange them instead of filling them.

 

Just bought my buddies refill station but I have one question, what size nut is it on the mother bottle? I need to go down to a -6 male but just need to know what size connects to the mother.

 

I got the nut with a -4 an fitting from the guys at Nitrous Outlet. Just give them a call and they will get you what you need. It was under 10 bucks.

 

Just called and my fitting will be on the way with my LT1 plate muhahahhaha.
