boost + NITOUS!!!!!
Nitrous is definately going to respond differently when used in combination with another power adder. Can you give us a better idea of what you are trying to do? What's the FI setup? How much power do you want to make (both just FI and FI+Juice)? Are you using nitrous to gain HP or just for it's intercooling ability?

hp438/445tq...im gettin rid of the meth kit for nos
Ok. Now that I knw more about your setup here are my opinions:
I don't want to speculate as to how much power you'll make off of a XXhp shot, since there is so much variation. I can however tell you that it will probably make significantly more than a NA motor with nitrous added. I do, however have some concerns about the complexity of adding a nitrous system rather than just getting another pulley/upgrading the head unit and continuing to use meth to assist your intercooler.
Nitrous is finickey alone, much less when added to a FI setup. The only time I'd really be willing to deal with it if I was spraying a VERY small shot to help spool a turbo.
Here's my basic cliffs notes:
Pros: More power, Lower IAT's
Cons: More complicated, harder to tune, more expensive (refilling bottles is NOT cheap, especially compared to meth), you don't get the octane/fueling value of meth
Let me know if you have any other ?'s!

running a 100 shot on top of forced induction would be more like a 150-175+ shot on a naturally aspirated setup... It's common for turbo cars to spray small shots to:
1) Help turbo spool quicker
2) keep iats down
You should be ok on that 50 shot... maybe a 75 max. but honestly if ur lookin for more power after that, then I would just upgrade to the d1sc and stick to one power adder for a street car...
1) Help turbo spool quicker
2) keep iats down

I know the last engine I personally worked on wit this kind of setup was a big turbo, built motor 1.8T GTI spraying a 35 ish shot... It gained about 80 HP from that.
If you're only going to spray 50 on it, I'd seriously consider ditching the idea and getting a smaller pulley/upgrading the head unit and keeping the meth on the car! If you're totally set on the nitrous though, let us know how it works for ya!

Id do a pulley swap and keep the meth, thats the best most reliable power IMO.
For reference, on my setup a 50 wet shot on top of 9psi made an additional ~50rwhp and 125 rwtq.
Start small, and keep a close watch your timing/knock and A/F.

There is a big varience in opinion on this post so Ill add another..lol
We have done alot of Boost plus juice.. You could not ask for a better performing combo!
The cooling affect alone will make a huge difference and you can count on the set up responding completely different vs a N/A application. I suggest starting with a smaller jet and working your way up until you hit the power level you are looking for.
Personaly I would also get rid of the water meth for the nitrous as well. Some people run both but in all honestly I have no idea why. I am all about keeping it simple. They claim you can run more timing with the ater meth, well with nitrous timing is an engine killer.. If you want more power just go up on the jet.
In the past we have taken cars that were at max boost working the system and car to death and backed the boost level down and added more nitrous. As a result we were ale to get better, more reliable horsepower and keep the temps down..
As you move up in the power level you need to be reading spark plugs.............
