Kenne Bell on a fox why is it rare?

[Nicoleb3x3]

I've been to allot of shows....and seen allot of cars online; I can't recall seeing many kenne bell fox body stangs...why is that?

I really want to run a kenne bell, and I think I've made up my mind on that....course I'm at least a year away from that but thought I'd get a discussion going.

I like the idea.

[Yumaguy]

the idea is awesome, the reason is that on the foxbody or i should say the 5.0 most people go with the vortech style because it makes more power than the twin screw style offered for the 5.0 motor. That and if i am correct the twin screw style offered for the 5.0 weights alot more because of how and where it is mounted.

[Nicoleb3x3]

hmm, well based on my research so far suggests the kenne bell has more at lower rpms (mid range) so maybe the vortech does give more on the top end.

I like to drive my car at mid range...flooring it to feel the supercharger isn't much fun on windy roads like NH has...plus I can't imagine how the kenne bell weigh's more than the Vortech with the typical upper intake....it can't be much different.

[Yumaguy]

i have only heard that it does weight more but i do not know that for a fact, but unless you are trying to make an all out race car i would not worry about the weight anyways.

Most 5.0's make power low and need help at the top end hence a centrifugal blower. KB's make big power down low so it is a popular choice for the 4.6 that needs help there. That is why I did not get one. Even my stock longblock will smoke any gear, all a KB would do is make the 5.0 traction problem worse.

[Nicoleb3x3]

ahh, but you forget I have an AOD! traction problem? what traction problem...lol

I guess I'm thinking about the way I drive...95% of the time between 2-3k; so that in my opinion is where I want boost. yes, the 5.0 is a low-end torque monster; and that's why I love it; but remember I have 262 ft/lbs torque and 201 HP with an AOD...I'd like to get 350 torque and 300 hp..I think that's a good number for me and how I use the car. I rarely lay into the car...and even if I did the AOD will help tame it. I've driven both auto and manuals...beleive me; a stick shift would be totally different story all togther I think I'd aggree with centrifugal.

So why not get heads,cam, and intake ?Then you have the power at pretty much all RPM's. Put you a torque converter and a shift kit in there before you do either.

[Nicoleb3x3]

I planned to do heads later, and leave the cam stock

[boss91gt]

Personally I would put the power adder on first also. Then the heads and cam would be for whatever power adder you choose. Going with the KB saves the cost of an intake. And while the stock cam is very drivable with major mods I would eventually have one custom ground. It is in my long term plan. If I had an unlimited car budget I think I would have gone the KB route.

The best built forced induction engines are the ones that were the best built N/A engines. In other words, if you build an N/A engine that puts out a good deal of power, the forced induction is that much better.

Trust me, I was in a rush when I threw the KB on, and I know better. If I was doing it all over, I'd do valvetrain, heads/cams, and bottom end before the KB went on.

The reason you don't see as many KBs on 5.0s has already been said:

Not as powerful overall
5.0s make plenty of low end torque

However, there is nothing wrong with it, but build the engine first, then add the KB. JMO

I have to disagree with the KB adding more weight than a Vortech. Adding a KB to the 5.0 would require removing the upper intake and bolting it on. Vortech adds the blower and tubing and keeps the upper intake on. I would think there wouldn't be much difference in weight.

Roots type blowers make power through the RPM range and centrifugals make it at the higher RPM range. IMO with your setup and with no intentions of making a full out race car, the KB should be fine. I would get the GT-40 lower intake and opt for the Blowzilla.

[boss91gt]

If you make enough power who cares about the weight? I think the KB uses a gt-40 lower anyway.

[91GT347]

If you make enough power who cares about the weight? I think the KB uses a gt-40 lower anyway.
Hmmm. That could be the reason too. A GT-40 lower will seriously restrict flow in the upper RPMs. On a 331,even with a Comp box upper,its dead after about 4700.

[YsOffcr]

No, the KB comes in two versions one for the standard stock lower and the other is for the GT-40 lower. I think that if someone has a different intake setup, such as holley, edlebrock, or trick flow its easier to by a vortech, paxton, or procharger to bolt on instead of buying a gt-40 intake or putting the stock one back on.

[91GT347]

Yeah. Most that would buy one already have a intake.
