nitrous enrichment fuel cell

How much fuel do you use with one ten pound bottle of nitrous. I want to keep the enrichment tank as small as possable.

depends on 1/8 or 1/4 and how much you are spraying
a 3 gallon tank should be plenty

1/4 mile and 250 hp

a small 3 gallon should be fine for 1/4 mile 250hp

If I understand you correctly your talking about a nitrous only enrichment cell ?? If that's the case a 1 gallon cell will be fine. Your system doesn't use as much fuel as you might think just for the nitrous.. Thanks, SJ

I run a 1 gallon enrichment tank on a 250 shot and I get several runs before the fuel goes to the level of the foam in the cell. Then I add a quart of fuel and go another few rounds.
