thanks n advance!

 

Goals? Budget? Driving style?

Search?

 

Breathegood pretty much nailed the questions. If you're looking at staying with the stock motor and not dealing with forged internals, I'd say stick with a supercharger, most of the supercharger kits being sold now will get you a safe 450-500RWHP on the stock motor. If you want to be making more than say 650RWHP then what type is a question on your driving goals, and it'll take more than $15,000 to get there regardless of which type you do... unless you work in a machine shop, are a skilled welder, do all the work yourself and have an "in" for the parts.

 

Yes, supercharger no turbo. I have 305 too. Nitto 555r as a daily driver DR. They fit easy too.

 

If it is a daily driver you should look into pro-chargers too.

 

The 4.6 3v responds well to both supercharging and turbo charging. We offer an intercooled single 76mm turbo system That will support up to 800hp on a built engine. The kit is sold as a tuner system, so no fuel or tuning components are included. Below is a video of our system on our 2005 Mustang GT, there is a dyno pull at around 2 minutes.

 

I have ran 3 different power adders. Saleen SC (twin screw), Procharger (hated it), and now a turbo.

For the street IMO you can't beat a twin screw, whether it is a Saleen, Whipple, or KB. All 3 can be setup to make you around 480-490 rwhp safely without any major fuel system upgrades other than injectors and a fuel pump or boost-a-pump. They can be tune for 91 octane safely or 93 if you have that available. They are a blast to drive around town with because of the instant tire frying low end torque. A twin screw if tuned properly will also not effect your gas mileage greatly, I am driving my buddy's Mustang with a KB SC on it, and it is averaging 20mpg with 4.10's.

I don't have anything good to say about Procharger so I will just leave it at that.

As for the Turbo, if you plan on primarily drag racing the car, IMO a turbo with the proper setup can't be beat, I absolutely love my setup, the power comes on hard and remains all the way through the pass.

 

I bought Danzcool's whipple setup when he went for his built turbo'd longblock.
For a primary daily driver, the "instant on" feel of a twin screw is awesome. The seat of the pants feel is awesome... Gone is the old stigma of "turbos are for imports" however.

I would stay away from hair dryers (i.e. prochargers). Nothing good to say about them, ever.

I love the whipple, it has the vacuum bypass on it, which keeps it "out" of boost for daily driving... I manage 23-24mpg highway (72 miles one way to work each day) by driving 'normal'

BTW Dan, putting on a set of LTs soon... then hoping to get a real dyno tune instead of this mail order crap until I get a new shortblock....

 

That sounds awesome. I know when I switched from stock exhaust manifold to shorty headers (& the FR throttle body), I picked up about 40HP, I figure the throttle body was good for 10-15, so with longtubes... yeah. THe dyno tune should get everything perfect.
