As for how much more hp and torque it's this; if your car is stock with a supercharger it's likely to gain 50-60%. Twin turbo can get your car up to 500 which is more than double your power output stock. Only issues is the stock engine can't handle that much power and you'll need to build your car up for it. With a single turbo I know you can get 300-400 probably more depending on boost and size of the turbo. I would only really recommend this route if you are planing on building up your car more than bolt ons. Hopefully someone who has turbo'd a six banger posts as my knowledge of using a turbo with this year v6 is limited at best.
A turbo can actually be done and had for a lot cheaper then a SC. The money comes in with the tune. They are very hard to tune and takes a good amount of time even with an experienced tuner.

Its good for more then that, id say 350 to 400 rwhp. These are very good, strong motors, just hard to get a lot of power out of them.

I just saw a video of a stock bottom end 3.8TT run 11s so they can handle it.

Over on v6power.net, there's numerous people getting 500-600 hp out of a 3.8 based motor. Granted they are stroked to 4.3 with power adder, but you get the idea.

What would be a good blower to get? I'd like something that would fit under the factory hood. Going turbo sounds tempting but money and reliability is a big factor.

Vortech and procharger both make a good kit. Other then modding your front bumper a little for the intercooler, its a fairly straight forward install.

Make sure you upgrade your injectors and fuel pump as well (an SVT Focus fuel pump is perfect) so that your not cutting out when under boost.

A stroked 4.3 most likely has other things like forged internals. That's what most people do when they have it bored and stroked. All the parts they put back in are forged that's hardly a stock engine. Forged internals are your friend. but you won't need them till your past your limit. That won't happen with just a supercharger so enjoy!

Yea, I figured that went without saying. Still a 3.8 block. You would do the same for any
V8 or bigger making the same power.

Yup it's the stock block. You rarely if ever need to change the actual engine block. Forged internals are great. It makes it easier if you get a bore and stroke it at the same time so you can kill two birds with one stone.

Well look at this way your already either paying or putting in the forged internals yourself might as well bore and stroke it. Being able to handle even more power is just a plus.

When I get my blower after my CAI, dual exhaust, and tune, should I get the blower from americanmuscle.com or is there another website that I can get one from for cheaper. I've been looking at a procharger kit on americanmuscle.com

Does $4300 sound right for a supercharger kit (procharger) for my mustang? A co-worker said that's too much, and it should be no more than a $1000.

There's not going to be a price difference between a GT or V6 S/C. They still utilize the same components. And 4300 sounds about right for a procharger. Vortech would be a little cheaper more then likely.

As for finding one for 1000, the only way you would spend that would be to buy it used.

I was getting at for that much money I'd have a GT not a charger

No matter how much money you throw at your car it will never be worth as much as you have in it

Would it be safe to buy one used or should I get a new one. I'm not rich what so ever but I have a decent job and am some what able to save for it. This is my first Mustang and I f***ing love it, and am willing to save my money to supercharge it.

Makes some friends, find a used kit and a mechanic you can trust to fill in the blanks.
