Is Nitrous safe for my set up??
 

I really want to try out the spray on my 91 GT but not if it is going to destroy my current set up. I have a 10.5 to 1 compression 331 with 24 lb injectors and a 155 lph fuel pump. The anlayzer tells me I make 334 average horsepower so I type in 420 avg.(guessing for a 100 shot) and the analyzer tells me I'm under injected and my fuel pump is almost not large enough. My builder gave the rings a little extra gap because he knew I might like to try the spray. Does this mean i should forget the NOS or should I be OK??? I was thinking maybe a ZEX wet or dry system but not if it will kill the engine. Help!!!

The only time your injectors would come into play is if you were using a dry shot. The wet kit has it's own fuel ( it taps into your schrader valve). You would have to upgrade your pump to at least a 190, but in my opinion a 255 would be better safe than sorry....
good luck

3 Pieces of advice for you here:

#1 FUEL
#2 FUEL
#3 FUEL

Make DARN sure you have enough fuel pump to supply the added nitrous shot. If not, bad things are sure to happen SOON.

My $.02 I wouldn't spray her until you upgraded AT MINNIMUM the fuel pump. ;)
