Need help

I think Vortech has their own intercoolers for their blowers.

As far as Cams, I think Crane has a set of blower cams for the 4.6.

With a blown application on the 4.6, depending on your setup (fuel system and injectors) and the year of the car, you may HAVE to change out your MAF (or at least re-program it).

I have heard of 99+ modulars using the stock MAF and an ECM module, "chip", to compensate for the increased fuel needs. (Larger injectors)

But in most cases, when going to a blown application, I recommend an after-market MAF unit that is programmed for your specific application. You will see increased performance and less drivability problems.
