Nitrous plumbing A1A...??..

I actually gave it a dry test with the carburetors off. On the fuel side I had to test and make sure I was getting the correct fuel pressure when the solenoid was open. So I turned the fuel pump on and turned the arming switch on had my wife push the button inside and watch the gauge well I activated the full throttle switch and watch the fuel. I just stuck a t-shirt down underneath the spray bar to catch the fuel from just going into the engine. I also had to jump the ground off the low pressure switch so I wasn't using the window switch. It activated perfectly. For the nitrous oxide I just disconnected the hoses from the plates and hit the button with the ground grounded and it shot out.. so I feel confident when it's time things will work as I expect them to.
Again I'm not a street racer and the car has way more than enough for driving on the street. This was all something I wanted to do to learn about nitrous. This of course after a couple calls to Mike thermos at nitrous supply.. and if anybody ever has any questions I would call nitrous supply and ask for Mike thermos.. very nice guy and easy to talk to... (Look him up)..
Again the track awaits the nitrous LOL..
I have SRP sportsman 4032 alloy forged pistons vs 2618 alloy pistons.
Is there a safe ammount that can be run with the 4032 higher silicon pistons?
