Yes and no....
Yes you can do it.
Yes it would make more power than an NA setup alone.
Yes its a good way to learn.
No you shouldnt do it if--- you are completly clueless, if you have your oil changed at the dealer, then no!
No I dont suspect thats you, but for anyone else considering it... well the real way to do things is to do them yourself, otherwise you have to pay way to much for way to little.
On a 3.0 motor... hemm I would consider any of the already tried and proven formulas. 8v 3.0 or a stroked 2.5.
Large displacement is going to give you lots of off boost torque, the SC will give you lots of on boost power.
Realistically with no intercooler or add on fuel. I would run a roots or screw supercharger. Set the pulley for a max of say 5 PSI to start. As long as the compression ration is no more than 9.0 or 9.5 with premium fuel.
You would see considerable power, neck snapping acceleration.
Why roots? Or screw? Simple, cheap easy to install, and off idle boost across the rpm range, fixed max boost, no spool up. Constant power.
Linear power curve.
Ideally you would simply use a variable fuel pressure regulator/FMU and boost fuel pressure to the stock 3.0 injectors... or go slightly larger injectors, use stock DME...
Or another direction is megasquirt. But to avoid clouding the post to much... email me or pm me and I can get into more details.
The flip side is a Centrifugal unit... it builds power based on rpm, similar to a turbo, but you do have constant positive manifold pressure, noticable boost builds and climbs, based on max boost level set.
This allows a more stock car... till you punch it then boost comes on hard and fast, this is also easier to tune from a extra fuel only when you need it perspective.
Simple and effective, the positive manifold pressure improves fuel burn and economy, its only when you jump on it that fuel delivery increases.
With either setup at 5-6 PSI, timing control other than stock is not needed and even with increased fuel pressure... the DME would self correct, using the O2 readings... MAF conversion is another thing to consider. In anycase... if anyone wants I can post pictures of turbo conversions in addition to superchargers.
