The quickest way to gain 40 hp

A fifty shot.

Are you refering to engine HP or rear wheel HP? 40bhp (engine HP) is going to be a LOT easier to obtain than 40 rear wheel HP (obviously).

The following is based on REAR WHEEL HP.....

Simple answer:

Cams
50-shot

Complicated Answer:

Full exhaust + full intake + tune

you will spend around $3K to get 300 to the wheels

If you install 4.10's . It will feel like you added 40 horse power.

+1. heads, cams, LT's, tune.........

260HP engines put down about 211-220RWHP. With a mid pipe, cat-back, and a cold air induction you should lay down 240-250RWHP. With pullies, TB, longtubes, cams and a tune, you could reach almost 300RWHP.

I'm fairly new to the 4.6 liter motor. I just bought an 02 Mustang GT, and it is rated at 260 hp. Thats a stupid number. I mean, why not 300? So, what I want to know is, what is the most cost effective way to bump this car up into the 300 horse range?

Just be happy with what you have for ****'s sake you just got the damn car.

Have you even detailed it inside and out, replaced all the fluids, and done all kinds of crazy excessive preventative maintenance on it yet? Do that first and give careful consideration to how you are going to mod it while you do that work.

Then do gears.

First, did you not know it was "only" 260 before you wrote the cheque? Or did you discover this after the fact?

Second, back in 1999 when the PI 4.6 was introduced, there was already a 300HP upgrade from Ford in the form of the 4V Cobra. The product map at Ford called for a sub-200HP base V6, a mid 200-HP GT and a 300HP Cobra. Obviously there were things under development like the 385HP Cobra R or the 390HP Terminator. Ford was probably at work on the conceptualization of the 3V modular but at that time, they designed what they did to meet their objectives in the late 1990s.

And third, you can see what it takes to get a PI-headed 4.6 to 300HP: long-tube headers and more aggressive cams, both of which fly in the face of Ford's many manufacturing, reliability, driveability, emissions, economy and who-knows-what-else requirements.

So, what I want to know is, what is the most cost effective way to bump this car up into the 300 horse range?

Cost effective? Bolt on a 75-shot of nitrous.

Or you can spend $2k for 370rwhp by doing a budget vortech setup.

You are going to need more than 300 flywheel horse to beat LS1 powered camaros. They have a very nice top end. I would spray a 75 shot You will gain 75 horse and even more torque.

What kind of K-member brace is that in the picture in that link? Is that for a convertible?
