Question 300bhp mods??

Is it possible to reach around 300bhp from the 4.6? with a few simple bolt-on's and a map?

Or would it need head work?

Don't have enough coin for that ATM but it is something I will be interested in when I do.

I've heard good things about the BBK throttle body and upper plenum, maybe an air filter upgrade and exhaust mods?

Last garage in the UK doing the supercharger upgrade was Dreadnaught in Callander but they stopped some time ago. Not aware of anyone doing it now.

I already have the X power rear boxes? or is there a full x power system?

I was hoping to get a BBK throttle body, but perhaps the Accufab is better? Although I seem to remember reading something about Accufab sometimes having a loose throttle plate?

I'd also like to have a full length twin exhaust made up with an X or H pipe in the centre in the future too.

i had an Accufab on mine for 10 years, no problems.
XPowers are just the rear boxes.
