Tiered of inflating kites and hearing of problems with Scorpega pumps I am planing in creating a compressed air system in my car with a pump used for air suspensions http://www.airliftcompany.com http://www.easystreetair.com/index.asp

Has anyone assembled such a system? I believe total cost should be around $400 max.
If you need to inflate far from your car you can take a small qwick connect cilinder of 6 to 10 liters to the beach instead of pump or battery systems.
I am also curious aproximately how many liters are necessary to inflate a 16 m C kite?
first of all as others have mentioned, pumping up your kite is a good warmup.
second, buying an electric pump and a spare 12 volt battery is way cheaper, we are talking
$80 for a decent west marine high pressure 12v inflator pump or $200 for that very nice BST pump.
third, count the pumps it takes to losely inflate your kite, it should be about 40 for a huge old 16 meter C kite, and since most hand pumps have about a 5 liter stroke, that's 200 liters approximately to inflate your kite.
fourth, this is a cool project, I suggest instead of buying some crappy air suspension you do it right and buy a used scuba compressor, and then fit up attachments so you can put either a small paintball tank on it, and play paintball or fill your buddy's tanks, or let your scuba friends fill up their tanks with it, since a scuba/paintball compressor can fill to 3,000 psi, you only need to lug around a tiny little paintball tank to fill up your kite.
If you are trying to use this air suspension it will only get up to between 100 and 200 psi, which means you will have to carry around a tank as big as a keg of beer to fill up your kite. Which begs the question, why are you carrying around a keg of air to fill up your kite instead of just hand pumping.
Go for the way cool route, get a serious $5,000 scuba/paintball compressor and do it right. Someone else posted a link of someone filling up his kite from a scuba tank . . . very cool.
I dont know about your launch site but it certainly is not convenient to have to inflate your kite right where your car is. A lot of times, the launch is a hike through some obstacles and requires inflating the kite at the launch not the car.
