i have been using 1.25 lb bottles,that work well but pressure starts to fall off quickly,i just put together a deal for 2 brand new nx 2.5 lb bottles with brackets for 125.00 to my door,almost sounds to good to be true,bottles will be here next friday

i use 2 lb bottles on the busa,pressure and performance is much more consistant with the bigger bottle,it should be a nice improvement on the 12

I use 2.5s. Good for 1 mile :wink:

Don't forget to post pics. :)

i got the bottles on friday,they are brand new as stated,i froze it ,filled it and mounted it,only to find there was only a 1/4'' clearance between the tire and bottle,not enough with tire growth at speed,the axle is at the end of the slots....will have to go with a longer arm to run the big bottle,anyone have a + 3'' laying around ?

Mcintosh has one sitting there, ready to go.

Ask me how I know...lol.

did you order a + 3'' arm ? have them send it to me,all my troubles will be solved

not sure what to do

1) nothing
2)send them my current arm,have billet ends put on
3)send them another arm (have one here) +3,maybe add billet ends

Will you be selling the 1.25 bottle

i can't sell the bottles (i have 4) until i get the 2.5's to fit

you can pick up a 1.25 lb alum. bottles at walmart for about 25 bucks,same as any n2o tank,and pick up a valve at any speed shop

i got the big bottles to fit,did some modding on the mounting bracket,with a brand new tire i have about 3/8's of an inch clearance,close but should be ok

heat/bp is an even bigger problem with the larger bottles,so i ordered a pressuire pro (wms is out of stock,won't be here until next week) 2 outlet ports on it,so the pressure sender will screw right into it,no more fittings (potential leaks) then i have right now, and 2 more nos 2lb bottles,should be good to go by the end of next week
