Hi. I'm new to this forum. I was wondering if the Kenne Bell supercharger was worth the 5k they're selling it for. Is it possible to find it elsewhere for less money than Kenne Bell. Basically, I'm looking for a supercharger setup that puts out alot of power. I have a stock 2004 GT. The Cobras are just way too much money. Thanks.

 

kenny bell makes osme of th ebest complete kits around i dought you will hear any if at all bad things about them. but they are alot of money. if it was me i would go ATI, but everyone likes different things if you cna afford the kenny bell do it. they make *** load of down low power due ot the twin screw blower setup so its a good blower for the down low grunt out of the hole and still has power in the middle and some up top also.

 

Thanks. That's what I wanted to hear. I was thinking about getting 4.10 gears and then a Vortech or Paxton supercharger. After I read the Kenne Bell site I thought maybe I'd go that route. Doesn't Whipple also make a twin screw?

 

they sure do. but as for the gears. unless you get stick tires your gonna have a hard time getting the power to the ground with a kenny bell and 4.10's. if it was me i would leave the 3.23's or maybe run 3.73's with nitto drag radials out back.

 

If you are looking for a fast street car, I would go with the KB for sure. I am tossing up the idea of a supercharger myself, and if I get one it will be the KB without a doubt. Well worth the money IMO. There are tons of opinions on which setup to go with also. My car isn't going to see the track much at all, so KB is a great option.

 

Thanks again. That was the original idea. I realize the 4.10s would be too much or at least not needed. What do you think a good exhaust setup would be? I'd like to go with some sort of kit since I don't want to piece it all together.

 

Exhaust is a big bag of beans man. There are so many setups to go with. I would get some kind of catback for sure, you can do the install yourself with no problem. It all depends really one what type of sound you like. I myself have the SLP catback. It is loud with the stock H pipe on. With a different mid pipe on it will get louder, and if you get an off road mid pipe, really loud. But it isn't so loud that you will get a headache driving however.

 

So for exhaust I'm looking for something just a little louder than stock. I also drive a 1967 Plymouth Belvedere with glasspacks. That doesn't seem too loud to me. Yes I know it is a non Ford, but I've learned. Mainly I guess it's all about flow. Are there any sites out there that have sound clips so I can hear their exhaust? My GT is stock; for the moment.

 

Looks like you have to register to listen to sound clips now,http://mustangexhaust.com/

 

Mustangexhaust is a great site. If your gonna do both a catback and mid-pipe, then find a combo you like on that site. If your only looking for a little louder than stock, I would suggest getting a mid-pipe of your choice and leaving the stock catback. Heard a 02 GT with just an O/R H today and although alot quieter than mine, it still sounded pretty darn mean

 

Yea, the KB will give you big block power all the way thru the tach from 2k to red line. Dont get me wrong the Paxton and Vortec chargers are great but may not be the best for the street. They give you that top end charge, this is where they hit full boost. This is great for the track but haow many times are you driving on the street at 5500 rpms? Cant beat the feel of full boost at 2500 rpm and lighting the tires up. :evil6:

 

yeah i would not go with the paxton or vortech unless you plan on spending alot of time in the high rpm's on the track. Kennebell setup might be a bit pricy but they include EVERYTHING. They also provide that low end torque that the modular engine so lacks. I love KB but personally i want to go turbo.

 

oh yeah and i would not go hight than 3.73's if you ever want to hook up

 

Kenne Belle is pretty expensive, but you also get a new intake with it. If you go with a Vortech or something, you'll need a aftermarket intake for max power.

 

But with the KB that instant boost will make the tires smoke fast. If it was me and if i ever sell my Nitrous kit, then i am gonna go ATI its builds boost so you can start moving before all the power hits. But i can see where you are comming from.

 

The one big reason I'm sold on the KB is that the centrifical superchargers require higher rpm's to reach their full potential (max boost). This was great for the days of the 5.0 with forged internals but with the new MOD motors with the powder cast rods high RPMs are the killer. Dont get me wrong, I ran a PAxton for several years on my 90 GT. I loved that top end hit of the Paxton, but with that 5.0 I could turn her all day at 6500 rpms and she would never blink. Turn the 4.6 like that and she'll add another breather hole in the side of the block. The KB will give you full boost without the high RPM's and as much HP as the other blowers without the added stress of the high rpms.

 

My whole idea is to have more power all around. It takes awhile to start pulling. I figured I could put one piece on at a time. Then I realized that might not get me exactly what I want. So I might as well save and get the KB. That way I'll get it right the first time. Then I'll just have to see how long my tires last. :icon_thum Still debating on the exhaust. I'll have to save for that too.

 

whats the safest psi for a stock engine? ive read 8psi should be the max ...

 

It all depends on the tune. KB's tune allows 9psi on 91 pump gas safely, after 9psi your are taking a risk with the rods. Like I said before it all depends on the tune and on how well you take care of your engine.

 

I use stock headers, welded xpipe (cut off 2 cats), 2 prostreet spintechs, and stock tips. BAD *** ROAR!

Any way you go a blower will add a ton of stress to the bottom end. I would think the initial low end power would actually stress the rods and crank more than the RPM's would. I have raised the rev limiter on my stock 99 and turned it over 6 grand on a regular basis in auto-x w/o problems. Add some 315 stickies on big wheels and you could probly do wheelies with the KB. LOL BTW, the KB site says DO NOT CHANGE FROM STOCK GEARS with their kit.

 

Actually you have it backwards, the high power does not stress the bottom end down low. High rpms will kill these motors. The KB is a good choice for a street driven car. You can spin these motors at 6000 without any problem, just not at that rpm with over 450 rwhp. The oiling systems in the modular's is it's weakest link. The most common failure you will see is spun bearings. The oil cannot drain back to the pan fast enough. The KB's intake is no good, the only make it so you don't have to cut a hole in the hood and add a scoop. There is no runner length at all. But with that being said it really does'nt matter since you are forcing the air and fuel through via boost anyway. You will not be able to launch on the streets with a KB, you'll have to do it from a roll or you'll just spin your tires. Think about where you want to be most affective, you stand a much better chance of launching with a Vortech or Procharger and they will pull harder up high. I like the KB but they are too expensive and harder to tune than the Vortech's. Steeda has a chip for the Vortech that won't void your warranty, that's because they worked directly with Ford.

 

The Kenne Belle will produce greatly stress on the bottom end at lower RPM. This is because you get nearly full boost as soon as you put the pedal down as opposed to 2-3 lbs. with a Vortech until 5000 RPM when you get full boost. The short runners actually let the motor breath easier on the top end of the tach. Launching a KB equipped car will be tricky, but not any harder than a Cent. blower with gears. Again if your car is a street car and you want to actually feel the power of your blower and all the $$$$ you spent....go Kenne Belle

 

alot of people use roots type cause it has the ability move a larger mass alot quicker off the line as ooposed to the centrifigual types..

 

Kenne Bell + Traction = Killer!

400rwhp with Kenne Bell will always be faster than 400rwhp with centrifigual type, if you have good traction... KB doesn't lose boost at high RPM like others roots type s/c so it's really effective.

If you go Kenne Bell 1.7L at 14 psi (~500rwhp), you wont be able to boost anymore I think, so you can add good cams, head porting, headers, mid-pipe and you will reach around ~600rwhp and probably more if agressive tune with racing fuel. After play with weight reduction and put a drag suspension :brave:

 

Kenne Bell's make less up top as compared to the centrifigal. If you race alot and go to national event as I do you will see very few KB's. All Paxtons, ATI's and Vortechs.
The new KB 2.2 will start to show up at the track but it requires a built bottom end. You can run the KB 9 lb. kit with a stock short block as long as you keep the rpm's down. Don't mistunderstand me guys I like the KB but the high cost just can't justified to me. I talk to installers and they charge more to install them and have trouble tuning them. For cost you can't beat the standard Vortech kit with the Steeda/Ford tune. They put down a solid 360 rwhp w/o the aftercooler kit. That's all you need on the street. Add an after cooler and intake tube and your at 400+.

 

Kenne Belle has a 2.2 kit now for GT's, its the same blower in the 03/04 Cobra kits and has potential for 700 plus horsepower. The only downside is it wont clear the stock hood. Part of the reason for the extra cost of the KB is the aluminuim intake they have to manfacture for the kit. As for tuning, I believe the problem there is trying to let someone else tune the car.. Kenne Belle provides a chip custom burned for each application, except for the 2.2 kit. Granted the Vortech/Steeda setup is nice and reliable, but if you think 360-400 hp is enough for the street, you havent ran into many modded 03/04 Cobras or LS1 cars. :icon_rabb

 

For 700 hp I'll add a cowl hood. That's a bad A kit, serious power potential.

 

The Kenne Bell come pre-tuned with a chip, you can ask them what kind if power you want, safe or aggressive. so at 9 psi you can make 390-450rwhp. (ie: 400rwhp is safe with romeo and 450rwph with windsor)

Also, yes the kit is expensive but its very complete, and dont need to relocate things.

 

It is expensive, but well designed. It does come pre tuned but the tunes are not great from the shops I talked to. They are not real good at supporting the installers from what I hear. You would want a shop that has alot of experience with them to tune it. A KB will not be as fast at the track due to the fact that you spend only a short amount of time under 4500 rpm's ( just 1st gear). KB would be faster for a 1/8 mile car. KB would also feel better on the street because of all the low end torque.
