Questions for centrifugal blower guys

I run a procharger at 16lbs through a carb shop blow through..
I use water/meth injection. It all works very well on top of a 474.
The carb has major prep work.. You will want to have a good carb.. Expanded bowls, preasure equalized.. power value protection etc..
You will also want to tune on a dyno with proper 02 analysis to get your fuel curve proper..
