Howdy P.R. 114....
Nitrous is a bunch of fun. We ran a "cheater" set up on one of our drag sleds. Built with Polaris triple. Ran like a scalded cat. Best top end run was just shy of 140 mph. 139.98 to be exact. Using a NSSR regulation 1/4 mile shaved ice track.
We used a basic setup from Chopper City and tweaked it from there. Mounted a rather small (2lb?) bottle in a hole we hogged out of the seat cushion. Accessed the valve through the little "trunk" flap.
A word of warning. Until you have the jetting dialed in, you WILL go through a few pistons. The introduction of nitrous (on the bottle) creates a excessive lean condition. Without a good set of EGT gauges to monitor your temps, this lean condition creates heat so fast, you'll burn it down in a heartbeat. Even before you feel or hear something going wrong. Heads, cylinders, bearings, even belts are put through hell when using the button. Hey, instant horsepressure costs plenty.
My suggestion to you (my 2 cents) is....
If this is to go on a "daily driver" trail basher. Take another route to get more power. It will be 100 times more reliable. If you REALLY must have nitrous, go for it. BUT, start off small. Very small and work you way up from there. Nitrous is tricky stuff so be prepared for a few new parts here and there. And EGT's are a MUST.
Don't get me wrong. I'm not trying to pee in your wheaties. Just relaying a bit of my own experience.
A bottle fed sled is a great time. And I WILL build another one some day. Maybe out of the XLT I have now. Or maybe pick up a older model Storm and really make a big motored, killer ride. but that will have to wait until buy a new sled next year. Gotta have something to ride while I'm wrenching ya know.
Have fun......Dan
