if you guys are mounting your nitrous before your MAF sensor your asking for problems. your car will sense denser air and try to adjust for it. causing your car to possibly be run more rich and put you in danger of a backfire.
warmongers idea is actually what i am going to do, but i am going to use 4 nozzles, as a two stage system (two nozzles per stage) right after the throttle body in the UIM, where it is still one (before it starts to split into six different ports)
by doing this, no i dont actually have a direct port setup. but, like warmonger stated, i want a bit of distance to let the nitrous and fuel mix together properly, it is better surge resistance. the only reason i am taking my setup off of the intake and past the throttle body is so that the nitrous can enter the intake manifold where it is actually a larger area than the intake tube. the nitrous/fuel mixture also doesnt have to pass over and under the throttle body. his setup will cost you the price of 2 hard lines and fittings, another nozzle and two of the same jets of your choice. my first two nozzles (first stage) will be 2 35 shot jets. my second stage, (run off a button) will run two 50 shots. that will equal a 70 shot for the first stage (2700 rpm to 4500 rpm) and a 100 shot (4500 rpm to redline) equaling a 170 shot (woops i said 200 earlier) the only thing i am worried about with that setup is if the nitrous is going to go into both lines at the same pressure. i guess it's all going to the same place so it doesnt matter so much.
with the stock SVT Upper intake manifold, there is one downfall. the cylynders furthest from the throttle body get there nitrous feed slightly slower. direct port would even it all out, that is something to keep in mind. i am not sure if the 3L upper intake will fit on the 2.5 lower manifolds but if it would it would be much easier to get even nitrous flow off of that, from the looks of it.
my .02 cents for anyone that wants it

I never said it was BEFORE the MAF...i just said it was in the MAF. It is actually...right beside/slightly behind the sensor on the TB side of it. There is no nitrous actually going into the sensor...i made sure of that.

yea, thats a generally knowledgable thing. I don't think anyone is running the nozzle preMAF.

There is actually, I believe an NX dry kit out there that has a ring that goes around the MAF in the front and sprays in it, to 'trick' the MAF to read a denser air reading, and adjust the fuel accordingly.

While this thread is still jumping... is there a generally recommended place to tap for fuel? Also, I already have an aftermarket fuel pressure sender hooked up for my Autometer gauge; if I install a tee at the end of that line, and mount the safety switch there, will it read correctly? AAAAND what pressure should I get?
Thanks all!

I forget the name of it, but it's part of the air filter. It sprays in at the top of the cone.

Yea, I remember seeing that before. What I meant by my last comment was that the people you hear about on CEG with our platform cars, generally know to place the nozzle after the MAF. It's a question that comes up now and again (as I'm sure you know) and people are always directed to place it after the MAF.

Tap at the Schrader? Or should I mount the safety switch there? Sorry, I'm just trying to figure this out, as I'm ordering from Jeg's, and want to see what fittings I still need.
