175 shot? Wow, there are a few things to worry about when spraying a Wet Shot of nitrous that high. If your looking at something that high, what about a plate system? That would probably be idel.Is your fuel system up to par? (fuel pump? sensors?)You would want to run some colder spark plugs and back down the timing quite a bit. A windows switch and fuel cut off switch are a must. (unless you like blowing stuff up. ) And I would definitely be tuning this on a dyno; 1. for safety of the engine and 2. for performance.

Post up some numbers and Good luck...

Nitrous is very unforgiving, and stuff happens very quick... Here is a picture of what I have now concluded to be low fuel pressure i.e. bad fuel pump...
