NO2 cost

dependson how much extra power u want to try and get from the engine.. try a search on google for "nitros kits" keep " the brackets in the search

It's typically in the range of $3.00 to $5.00 a pound, depending on where you get your cylinders refilled. How much you use per flight depends on a *lot* of variables besides motor tank size.

For example, ambient temperature affects the nitrous density. Colder temperatures will result in a denser liquid, meaning you'll use more nitrous per flight. Also, the volume in your fill tube is wasted -- longer fill tubes waste more. How long you keep the fill solenoid open after you start to vent liquid also obviously affects the quantity of wasted nitrous.

For a HyperTEK "J" tank (835cc, IIRC), you'll usually use less than two pounds of nitrous, unless you vent for a long time, or have a leak somewhere. For a 200cc motor, you'll probably use around a pound, counting wasteage. Only way to know for sure, however, is to actually test with your specific GSE, so that you get a feel for what effect your fill line volume, etc., have on total nitrous consumption per launch.

Also, remember that you typically can't get the last bit out of the bottle in a useful form. So, a 5 pound bottle with a long fill tube might only be good for 2 or 3 launches, even though actual nitrous consumption would seem to indicate you could get 4 or 5 out of the bottle.... As always, your mileage may vary.

Why would you want NO2? Nitrogen Dioxide (very toxic)

Tastes great! Less filling! 8-)

Our club pays about $2.25 a pound, but we also buy it in 64 lb cylinders. A few Hypertek Ms goes through the gas quick.

Around here, if you're filling small cylinders, it's $4.50 per pound. If you lease a 65lb bottle, including the lease, it drops to a little under $4 per pound if you use one cylinder per year; it drops slowly as you use more gas, as the cylinder lease is per year, so each additional cylinder just has the gas cost, not the lease cost.

The $4/pound on lease assumes you can only use about 60lbs of the gas in the cylinder -- you'll never get all of it into your motor.
