More wet or dry questions.

I didn't want to hijack the other thread.

This is probably where I sound like a moron. At what point is the fuel added to the intake path in the 4.6? From reading the other thread it sounds like its added before the intake manifold but after the throttle body. And in that case using a dry system is safer. My understanding though is that with the SC the fuel is added after the intake right before the cylinder. I have always thought that a wet system would be better in that situation. Just hoping that someone could explain a little bit.

AFAIK, all modern multipoint fuel injected cars use a "port injection" system that positions the injector as close as possible to the intake valve. A single-nozzle "wet" nitrous system delivers both nitrous oxide and additional fuel at some point in the intake tract before it splits into the individual intake runners, which may be a considerable distance ahead of the intake port. "Direct port wet" systems use multiple nozzles (one or more per cylinder) to deliver N20 and fuel, and are usually located as close as practical to the intake valve in each runner. Single and multi-port "dry" systems inject only nitrous oxide, and rely on the fuel injectors to supply enrichment when the system is operating.

Hope this helps...

Here's the 4.6L intake manifold (NOS NOSzle Kit) clearly showing the injectors and the greatest place of all to inject nitrous oxide. Looks like the fuel doesn't have a very long way to go from injector to valve.

TCCoA, there's no better way.
