Ok guys and gals, I was browsing through Ebay like I´m sure most of you do and I ran across this http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1873887481 This is a cute, cheap little NOS kit. It uses Whip-it cartrides as its NOS supply. The website and this ad Hype it up WAY too much. The first down fall I see with the kit is the fact that it uses a cracker to open the cartridges. Anyone who has used Whip-it for purposes other that despensing whip cream (you know what I mean) that the cracker has to be tightened all the way down, then loosened to release the pressure in the cartridge. Kind of hard to do if you are driving. Also those cartridges empty quick, so I´m not sure how effective they would be on the track. Maybe good for a few 10ths, and an mph or two. Another problem is there is no provision for fuel enrichment. So as soon as you open the cartridge you will go WAY lean. Personally I would have put in a solenoid so you coud release the pressure while driving, and also have some kind of provision for fuel enrichment. Also using multiple cartridges would be better for a longer shot, and better ET´s.
