Nitrous with supercharger?
Can you run a dry shot of nitrous with a D1SC supercharger? I already have the NOS-5177 kit for the ls1 in my other car. I want to put it on my new 02' T/A with the supercharger. What all would i need to do this right? Could i put the spray nozzles in the metal air box or will the supercharger mess them up? I thought i saw a plate that goes in front of the mass air flow sensor for nitrous.

Sure, I run the NX MAF kit. Just remember a shot of nitrous doubles with FI.

What does that mean "MAF"?-mass air flow? I know that it is from nitrous express. "FI" stands for fuel injection right. Do you know the part #?

Of course you can run nitrous with it. In order to do any good, though, a) you may have to upgrade to bigger fuel injectors--the extra fuel required might excceed your current injectors, b) you'd have to have it tuned well, and c) you have to hope the bottom end can take it. If you have a stock short block I would suggest it will not: I saw someone with a P1 and nitrous split the block, not just a piston and the head.
You might just try a mild shot - 50-75, just to cool the intake charge. That sometimes returns really big results, and it means a bottle lasts a long time which can be important if you are out runn ing on the street alot.

Regardless, if I had access to good PCM programming (someone with LS1 and who knows what they are doing), I'd go with a dry kit unless I had to have a really big boost from the nitrous. Personally I stay away from wet kits because of the four racers I know who have lost their cars to n itrous cars, three were wet system fires, (the other was just a stuck nitrous valve/explosion that blew the intake manifold and fuel rails off). ((Come to thin k of it, these are the only four guys I know who have lost their cars to fires, period).

Well i gave Nitrous Express a call and he sudgested a "conversion Kit" that would convert it to a "wet" kit. That is what the MAF kit is. Id much rather stick with a "dry" setup though. The wet kit just seems to be more involved in the setup: gas jets and nitrous jets! I don't want to have to get out of the car and readjust the mixture due to the outside temp or humidity. On the "dry" setup the compuer will adjust the fuel right?

And as for the original question on putting a dry kit on it, I don't see any issues... but the plate thing is usually after the MAF, not before, and are wet kits.
Your original question/plan is good... just don't put it too close to the MAF so you don't freeze it. You'll not only benefit from cooling the air down, but also from the added nitrous in it.

Ok then i will stick with the original 5177 kit just like it came from NOS. I will just mount the jets in the metal air box that came with the supercharger. That will be fine right?

just an addition... make sure to get the necessary safety features:
window-switch
WOT-switch
FPSS (Fuel-Pressure Safety-switch)
