Kenne Bell hands down, especially for a street car! The install should be straight forward, it's just a direct bolt on. I guarantee you'll be happy with any route you take .
I would have to respectfully disagree. If my Bullitt was a track / drag car, I would agree with you. My B spends 99% of its time on the road where the instant boost does make a big difference (to me anyways). Pricewise, if you add an intercooler, the Vortech and KB come pretty close in price. Just my $.02 and worth every penny of it...:lol:stang4.6 said:The insta-boost of the KB isn't really that big of a deal. Really, if you are running hard, street or track car, you are in the upper RPM's. So low rpm boost is meaningless.
This is an old argument, its been hashed out here and on every other mustang site on the net.
I've driven an '03 Cobra, and riden in 2004 GT with a KB. The power is great, and the feel is somewhat different, and the sound is very different. But the 'good feel' is because of the boost. Boost just packs more oxygen into the cylinders (that's a bit simplistic, I know, but basically that's it). It doesn't make that big of a difference it its made with a twin screw or centrifugal.
Every magazine that tests the 2 types of blowers against each other says the same thing: they are both great. The turbos always win over the blowers, but they are more expensive, more of a headache to install, and to tune, so most people stick with the superchargers. Some of this is changing with the turbos though.
What made the decision for me was price. The Vortech kit is the most inexpensive, it is widely used, most performace tuners are familiar with it, and it is very relaible. Added to that, their customer services is above average. I have nothing against the KB system, other than its too expensive for what you get IMHO. For the price of a KB you can have a vortech, cams, and full exhaust. Like I said, for me that's what made the decision.
If you can, goto some car meets and ride in a 2001-2004 with a centri and another with a KB. In the end, its about what you like on your car.
Oh, and I did install my Vortec myself, and it is very straight forward. Its been several years, but it is about a 30 page manual, with all the instruction and illustrations you need. Before I bought the kit, I downloaded the install manual off of their web site and read through it to get a feel for what the install would be like. You might want to do the same for the various blowers you are considering.
