nitrous

i was wondering what the dangers were of dry nitrous. if you could help me out id appreciate it thanx

its because dry nitrous depends on your stock injectors to provide the intake charge with enough fuel. If there's ever a problem that would prohibit them from giving enough fuel (for example hitting fuel cut on the rev limitter) the cylinder would probably detonate and you could snap a connecting rod or bend a valve.

can i know what mean dry nitrous???????
How many type of Nitrous do they have????
Which one is the better???

"dry" nitrous kits do not have a separate solonoid and jet to inject additional fuel into the intake charge. "wet" kits do. Cars that have returnless fuel systems have to use "wet" kits.
