do i got 40psi of fuel pressure? how do i know

Go buy a Fuel Pressure Tester. They look just like a compression tester but with different fittings. Any local auto store should carry them and are fairly inexpensive. I got mine through JCWhitney. Came with different fittings for different makes.

Running juice, you might want to look into an adjustable fuel pressure regulator. I'm no nitrous guru, but know that most people who run juice, use one of these.

Yes... Because its stock and stock we have 40 psi of fuel pressure at idle. Run it you will be fine.

For those of you who know nitrous way better than I do... along with the fuel pressure needing to be so high, doesn't that solenoid for the wet system help with that? Plus, I think if you go through say Brenspeed for example, when they give you the tune for the car to use with the juice it'll increase fuel a bit and retard the timing.
Anyone had any luck with this system? I was looking hard into it as well. I was looking at a blower, but this seemed like a sensible alternative, but I've also heard you f-up once and boom. I don't get on the car much at all, so nitrous would seem like a cheaper alternative, but I'm a bit paranoid that it'll end up doing more bad than good. Would a window monitor aleviate all the problems, or at least enough of them where you're not having to worry every time you hit the botton that your intake manifold is going to end up in a million pieces?

I've been doing some research lately since my 125 dry shot is getting installed next week The general consensus is that as long as you run a window switch a wet kit is a very safe way to make some cheap power on these cars. A wet kit by design will take care of the extra fuel required to keep from detonation, but some timing will still need to be pulled out of the tune.

The danger of detonation and possible engine damage (especially on a stock bottom end) are evident in both a wet kit, dry kit, blower, or turbo. A wet nitrous kit has the additional possibility of fuel puddling in the intake causing backfire/boom/no more mustang. This isn't likely when using a window switch properly though.
