Maximum HP to get from NOS

What is the maximum HP that I can get from NOS if I don't change my bottom ?

I mean with fuel pump ..

And I don't use NOS just for 1/4 mile I use it for 1 mile ..

Some guys told me 120 other said 125 ??

Did anyone change his bottom and what HP did he get ?

Right now, the most I know of is 125, and one guy blew a ring, but he was running lean... Good luck! :D

Was he using wet or dry ..
And what is the matchup of them please ?

I wanna go more ..

Thanks alot for helping :)
