I think I made this point in the last nitrous thread but I will repeat it here. A dry kit will in fact cause your motor to blow sooner than a wet setup will because of the way that the nitrous is injected. It is a constant spray into the intake manifold which is pressurized between 900 and 1000 psi. When it gets injected into the manifold it rushed down to the last cylinder where the majority of the nitrous gets sucked into the motor. This causes that cylinder to get a lot more nitrous than the first cylinder inline which means the first cylinder is going to run extremely rich. Some rich cylinders and some lean cylinders = not a good idea. Wet setup sprays an equal amount into each intake port on the intake manifold cause even distribution of the nitrous and all cylinders run at the same air fuel mixture level, meaning less of a chance of detonation, and less of a chance of blowing your motor. Yes a wet setup is harder to install, but it is well worth it....
