Was woundering what kind of supercharger to run. kenny bell or ati procharger, and if any body has installed one them selves if it is pretty straight forward. I also know that kb makes down low and mid range and the a procharger is mid to high. I had a procharger on a 92 gt and it ran really good but these mod motors just dont run like the old 5.0 did in the lower rpm department. This car will be a street car and dont car about track peformance.

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 :D.

It depends on what you want out of the car. A twin-screw is great because you have insta-boost and the power is there whenever you need it.

A centrifugal blower has to spool up similar to a turbo, but you're not in boost all the time. The cool thing about the centri is you can set it up to have a FMIC and a BOV...and those are always fun.

John,
I have the Kenne Bell blower that I installed in May. All I can say is I love it....the acceleration....the whine....!! It is a very well Engineered kit. I installed it myself. Its not necessarily a quick bolt on, but the 117 page manual is very well executed and thorough. I have no regrets at all!

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.

I agree, I have a kenne bell and it is awesome! I would not choose anything else. I also did the install myself, and it is not that bad, but does take time and patience!

I went the centrifugal route mainley becauce I feel that one of the most unquie parts about are Bullitts is the Bullitt style intake. I did not want to do away with the intake.

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:

I've been in a KB GT laying down 456 hp/493 tq and it was fun, but 1st, 2nd, and part of 3rd was worthless. It was a very fast car when it hooked. I had a Vortech on my old Bullitt and I loved it more than the KB. A: Like Blmalrow said the intake manifold is unique to the Bullitt B: I wanted to gain the most amount of power, which generally centri pull more power over positive displaced SCers (stating that both vehicles are identical in every aspect, but the difference in blowers). Yeah, centris take a little bit to build boost like a turbo, but when it comes on it's pretty awesome. I like the fact that I could use first-fifth gear without completely burning off the tires. I say get whatever makes you happy. Oh, yeah, price was also a factor in my situation, but it still came down to not wanting to loose the intake manifold.

My old B layed down 394rwhp/397rwtq peaking out at 9#'s right at red line with BBK LT, BBK Catted X, SSS Catback, and dyno tune.

Im a Vortech advocate, had the S trim, T trim and now the YSI......IMHO they are the best bang for the buck.
