Nitrous kit homemade? take a look

they are small cartridges (like the CO2 cartridges used in bb guns) that have nitrous oxide in them. they are used to make whipped cream at home, but more commonly used to inflate a balloon and inhaled to get the buzz from the n2o (honestly...i have never done this... ;) ...lol). I honestly doubt that these would make any substantial difference in horsepower on a V8 engine....hell, probably not a substantial difference on a riced out 4 banger....lmao
 
it's the laughing gas that dentist use, which is basically nitrous we use in our vehicles minus a few things so that you don't die when huffing it. honestly the kit says it has a constant flow, well let me tell ya from experience there isn't much nitrous in those bottle and yeah it might give ya 30 horse for about 2.2 seconds maybe. lol but in theory he is right it'll work, but don't waste your money.
