Turbocharging a 4.6 V8

GL op. I'm more a fan of popping an Eaton on there.

It's pretty rare that I mud, but I'd probably have a steel plate slide in in front for when I do and just lose my intercooler ability.
This will be a long te coming. I'll have to just buy parts as I have money and hope it works when it's finally slapped together.

you are getting into engineering territory. There are some things to think about. You cant change the acceleration enrichment by manipulating MAF signal. BUT you can manipulate it by raising/lowering fuel pressure. The way I got my supercharged A4 quattro to run perfect was by cranking the fuel pressure up to 60 lbs from 40ish and put bigger injectors in and then turned the MAF signal way down. In your case. you WILL need at LEAST a 1:2 rise in fuel pressure per PSI boost to get the airflow change in control. You wont make boost from idle so you need to match the fueling to the pressure curve. (you will have 2 enrichment points 1 off idle and 1 when boost hits, the computer is open loop at that point and too clueless to know that there is a turbine that is going to be pushing another half an atmosphere in.) You need to be there with fuel BEFORE the air hits.
