if i was to invest in something to add horsepower, speed and torque would i chose a supercharger or a turbo charger?

it really depends on which turbo brand and what super charger brand... if it for that 'stang in your pic then id say go for a ProCharger supercharger but ive also heard some really good stories of people using Garrett Turbo's on some modern mustangs and getting some decent results...

It just depends on what your goals are. Superchargers have instant boost and power. Turbo's make more power every pound of boost than superchargers. I would personally stick with a twin screw blower like a whipple or a Kenne Bell and steer away from centri blowers.

Per pound of boost, turbochargers will always give you the best numbers. Having said that, there's a lot that goes into a turbo setup that you wouldn't need to do with a supercharger. Personally, I'm a supercharger guy. The numbers are still awesome on Mustangs, and the power is right on tap. Installation isn't hard, and once you have it in there are a ton of different tunes and other parts to experiment with. Check out Vortech, Saleen, Procharger, and if you're feeling adventurous, Kenne Bell for superchargers. HP racing and Turbonetics have turbo kits for your stang.

I have always been more of a fan of Turbochargers than Superchargers. They are easy to replace if they fail and they are easy to add to a n/a engine, plus there are more compressor types and turbo sizes to chose from than with a supercharge system so you can custom tune a turbo system with any volume and pressure type you like. You don't have to worry about pulley ratios, power loss due to the pulley leeching energy from the crank, and custom fabricating mounting systems to engines where there are not any bolt on supercharger systems, the only part you would potentially have to custom fabricate with a turbo system is an exhaust manifold and down pipe. The thing about forced induction is that you aren't adding more horse power so much as more torque potential. With the added air compression you can (and should) run higher fuel volumes, thus it's similar as if you were to have a larger bore and stroke.

From experience, I know on a Mustang such as yours that a turbo would work better than a supercharger. I helped a guy put on a turbo and then another guy w/ a supercharger in the almost exact same car, and the turbo put out more power. So definitely go with a turbo.

That is because turbos produce more hp per pound of boost than superchargers. I for one would rather have a supercharger. I would hate to have to wait until the turbo spools to have power. I love the feeling of instant torque at my disposal.

i like instant power to kick some butt... i like the sound of super chargers best... but which one would truly give me the most bang for my buck

Supercharging gives you the torque low down, however for absolute bang for your buck you might want to consider a twin turbo with smaller turbochargers. If you went with multiple small turbos instead of one large one you will get the same sort of power-on-demand feel as a supercharger without losing as much power in order to run them. Superchargers constantly leech from the crank shaft, so even though the power is there on demand it is always taking away significant amounts of power just to keep it running.

I personally prefer superchargers.... but that's coming from a guy who drives a supercharged car... the power is always there and the noise is intoxicating. Turbo's have their place, and can be great, as long as you don't mind dealing with the lag, or go with a twin turbo.

the problem i got with turbo chargers is they run hot but i dont believe that superchargers run hat and yes the noise is intoxicating... i love it

It all has to do with your setup. If you have an intercooler and a good radiator, you're pretty good to go. For a mustang, I would go with a supercharger... one reason being twin turbos on a 03-04 SVT Cobra will give you ungodly, and almost undrivable numbers (700+rwhp). For any 3V-4V/cylinder Mustang except Shelbys, you wanna shoot for 500rwhp-600rwhp.. that's all you'll be able to transfer to the ground on street tires. Plus, the supercharger allows you to have more add ons and still be driveable. Stuff like a plenum, throttle bodies, cats, x/h pipes, custom tunes etc.

Yeah, you really don't want to run any turbo set up without some sort of charge cooler, but ideally you should run even a supercharger setup with a charge cooler since compressing anything adds energy in the form of heat. Like Apollo said it's all in the numbers you're looking for, a twin turbo setup on a mustang with say two T3 or TD04 turbos running between 5 and 10 lbs will get you a modest 300 to 400 hp depending on your fuel setup. Once you upgrade the internals to handle higher cylinder pressures you can bump up that boost pressure and potentially get 500hp or higher if you dial it in right. That's just to give you somewhat of an idea. Ultimately it all comes down to your preferences and what falls within your budget, though if you go turbo I highly suggest double or nothing with a Stang motor.

well then i certainly think that superchargers are the way to go now.... and you can even double them up... i think? and wuts a plenum

No reason to double up s/c's. lol.. intake plenum, or manifold.
