I contacted a local preformance shop in my area about dropping a charger in. I do not want to do it myself since I have no clue about the 4.6 engine (btw its a 2004GT).
This is what he said:
Now I asked if 10 psi was safe to run on stock internals and if the tranny can handle the theoretical 410rwhp and he said this:
Can the 4.6 engine handle 10psi?? I never ran that much boost on my old 5.0.... I don't want to drop the cash and then have my engine blow up 200 miles later or screw the tranny up....but I doubt the tranny could handle the torque caused by 410rwhp.....
This is what he said:
As another option, we are a factory authorized Procharger dealer and could do a 10psi Procharger Stage II kit with 3 core intercooler for
$4200.00 and install the same $750.00. 42lb injectors are required as
well for the 10psi kit - $300.00 This system can easily make 470 hp
crank and 410 rwhp.

As long as the car is tuned properly (we can do that for you) it won't be a problem at all. The only issue you may run into is sometimes the factory MAF will peg over 9psi, in that case an upgrade to a BIG MAF such as the SCT 2400 Big MAF for $260.00 will take care of that. I would strongly recommend dyno tuning the system as well, we can make sure the car is properly set up with the correct air/fuel an timing. A complete dyno tune will be $500.00 that includes air/fuel with wideband O2, boost, hp and torque.
