RE: brand new bullitt how should i upgrade.
Dude, I cannot believe you are asking this question! You bought an icon car and you want to make it into something else. Yo, wear a helmet from now on. You should have bought a GT and then whatever you did would be an addition. Now whatever you do is just a subtraction. You simly bought a very plain looking ride. Most of its features are suspension. If you have too much money, maybe you should have thought more about the Shelby GT. Then at least you would have a flashy ride. Seriously, do not to anything. Resale will suffer. Who would want a BULLITT that someone has messed with? If you do anything make sure you keep the old partsfor replacement if you have to sell it. The interior is barren and perhaps could use a real carbon fiber dash kit. Be very careful and sure before you do anything.

RE: brand new bullitt how should i upgrade.
Tbh, the top end on a centrifugal supercharger isn't all that much better than a positive displacement types supercharger. Personally? I'd go with the Kenne Bell. This is whatI originallyposted on IMBOC.com in regards to centrifugal's top end:
Well, look at the following dyno charts.
http://www.musclemustangfastfords.co.../photo_23.html - '03 Stock Eaton (14 PSI) vs same car Vortech (14 PSI)
http://www.musclemustangfastfords.co.../photo_22.html - '03 Stock Eaton (14 PSI) vs same car KB (14 PSI)
If you look at the dyno charts, you'll see that between 3500-4500 RPMs in a Vortech, it's only pushing around 275~375 HP, and the KB is pushing around 375~515 HP. Torque numbers at the same RPM range in the Vortech is around 370~440 lbs-ft, and the KB is around 580 lb-ft flat. Top end, the Vortech is BARELY better, around 720 HP vs 700 HP for the KB, and around 575 lb-ft vs 560 lb-ft for the KB. But how long are you gonna stay in the 6000-6500 RPM range? Even though the torque curve starts dropping off for the KB, it's still ALMOST as high as the Vortech, and as for the HP curve, the Vortech barely hits 600 HP at 5700 RPMs, whereas the KB hits it at 5325 RPMs. The facts are right there, you be the judge

The same article, only with 11 PSI vs 14 PSI. (I'm just gonna copy what I wrote above, and just change the numbers accordingly.)

If you look at the dyno charts, you'll see that between 3500-4500 RPMs in a Vortech, it's only pushing around 225~350 HP, and the KB is pushing around 350~410 HP. Torque numbers at the same RPM range in the Vortech is around 350~420 lbs-ft, and the KB is around 525 lb-ft flat. Top end, the Vortech is BARELY better, around 660 HP vs 630 HP for the KB, and around 525 lb-ft vs 500 lb-ft for the KB. But how long are you gonna stay in the 6000-6500 RPM range? Even though the torque curve starts dropping off for the KB, it's still ALMOST as high as the Vortech, and as for the HP curve, the Vortech barely hits 550 HP at 5700 RPMs, whereas the KB hits it at 5500 RPMs. The facts are right there, you be the judge.

NOTE: On the 11 PSI test, if you notice I compared the Vortech and KB at 550 HP vs 600 HP with the 14 PSI test, simply because 550 HP on 11 PSI is right around the same as 600 HP on 14 PSI (in terms of RPMs.) It's just a coincidence that at 11 PSI it hits 550 HP at 5700 RPMs, and at 14 PSI it hits 600 HP at 5700 RPMs. If I were to compare them both at 600 HP on the 11 PSI test, then the Vortech hits it at 6050 RPMs whereas the KB hits it at 6150 RPMs.
Much of it will depend on your gear ratio. With 3.73 gears, if you shift at 6000rpms then you will be landing in at just over 3500rpms for the 1-2 shift, 4000rpms for the 2-3 shift and will be landing at 4500rpms for the 3-4 shift. So in 3rd and 4th you are actually just landing in the perfect spot for the Vortech. With that same gear ratio the KB is losing 1/3 to 1/2 of its boosted power band. In truth, it would come down to the driver, but I think that with equal drivers in a drag race the centrifugal should win.
Although it is far from a perfect comparison, if you look at the Speeding Bullitts page you will see that that of the top 10 fastest Bullitts, #2-8 are centrifugal and #10 is the only KB. A better comparison would be to look at drag racers in general. Most use a centrifugal.
But for around town, I think that a KB would be much more fun.
