Default How big of a shot should I run with my setup?

Ive been thinking about putting a N2O kit on the truck. I was wondering what is the biggest shot I could run with my current setup without causing damage.
-STS Turbo GT67 w/intercooler and 44# injectors (running 10# boost)
-Snow meth injection
-Tranny: 2300-2500 stall converter, servo, cooler
- Exhaust: straight pipe, no muffler, no cats

I havent done anything internally yet. I also wanted to know what are some upgrades that would allow me to push more boost and/or more N2O.
Thanks

i would probably start with around a 30 shot, and go up from there monitoring all your engine's vitals.

keep in mind, with the boost, the hp output will more than double the size of the shot.

i think most FI guys on here that juice run around 40-50 shots.

The hp increase will not be double, lol. I make 50 from a 50 running thru my compressor. RW increase of course, but I do agree starting small and working up. 35 shot is usually the smallest available.
Most of the guys with SC run 75 shots on 9lbs boost, why not just turn up your boost?

I wouldn't doubt your injectors are near maxed out as is.

I keep hearing 75shot is probably good for my setup. Should I go with bigger injectors. And do you think I need to upgrade my fuel pump.

I havent turned up the boost because I heard that anything over 10#s is pushing it on the stock engine.

Obviously the more we push our setups the higher the potentail for failures. You have to pay to play with the big boys and that's all there is to it.
I know nothing of turbos but the guys i do know either run 60's and meth or a hell of a lot of meth with multiple nozzles or both! I run 60's at 61% IDC on 9lbs peak with meth. I imagine you would benefit too.
You have the stock fuel pump? I would upgrade to a 255lph at the least.

What type of fuel pump, injectors do you recommend?
