I have a 2005 4,6 f150, with intake, exhaust and a livewire tuner. I want to either do a supercharger, turbo or twin turbo. Which is best and better bang for the buck. I want to be able to walk all over the civics that think they're fast plus have the benefits for towing. Ive been told my motor can handle 500 hp and i would like to be pretty close to that. What do I need to do.

 

There's not much out there for the 4.6
So for you I would say go with a turbo.
A turbo will make more power at a lower boost level then a supercharger.
And like I said. There's not many superchargers for the 4.6.

If you are looking at the STS turbo setup, be careful to read the warnings. STS strongly warns against towing with an aftermarket turbo and stock block/pistons. Apparently the turbo is great for the base vehicle, but not when you add attached weight. Just my thoughts.

 

Go over to Got-Pressure.com, many peops over there have 4.2L and 4.6's turbo'd. 415-420 rwhp is about all a stock 4.6 can handle, anything more than that and your internals can't handle it.
