I'm presuming you're using a single nozzle in front of the throttle body, and the system is set up to run WET. The jetting 47/53 that was recommended is for the NOS DRY system. For a wet setup, you should run 47N/30F, with a static fuel pressure of 40-45psi. That is the jetting for a 100hp shot. For 125hp, try 55N/39F.
Before you do anything else, replace the stock fuel pump. Judging by the whining, and the loss of fuel pressure, that pump is on the way out. If it gives up while you're running nitrous, your engine will lean out and you will burn plugs, or worse, pistons. |
