Kenne Bell has a s/c for like $4000. There is also a Paxton one. I don't know what it costs. I have heard that the Kenne Bell one is really good. I have not seen a 4.7 with a s/c thought.

Kenne Bell S/C has issues with auto trannie? I thought Kenne Bell originally made the S/C to fit in the Jeep Grd Cherokee, which only comes in auto.

I have a 2001, 4.7, Quad Cab, 4x4, Auto trans., with the Kenne Bell Supercharger. The cost was $4000 for the kit, $500 for polished finish, and $800 for installation. When you accelerate hard enough the supercharger kicks in at 2200rpm and pulls hard up to 5500rpm before it shifts gears.
The problem is when driving up long, gradual inclines or occasionally passing people, the superchager kicks in even though you may not want it to. Once the charger kicks in the transmission doesn't want to upshift again until it reaches the 5500rpm mark again. To correct the problem I have to let off the gas to disengauge the chager, then the transmission will upshift so I can drive at a normal rpm range.
Overall I like the kit. I guess I just have to get used to the occasional shift problem. The kit says it adds about 80 extra HP which I can definitely feel. For that much money try to drive one before you buy. I'm not so sure I would have spent that kind of money if I had driven one first.

Mike - My brother and I had the local Dodge
dealer install Kenne Bell S/Cs on our 4.7 QC
trucks 60 days ago, and we're disappointed.
In short, the shift points on my tranny are all
screwed up (my brother's truck a little less so).
Even with mild throttle tip-in, the trans will
downshift and without letting off the pedal, it
won't upshift unless you begin going downhill,
taking all load off the motor. That's bad
enough, and like you, if I had driven it first, I'd
never have installed one on my truck. But I
also have a terrible detonation problem. With
ANY load at all (hills, towing light trailers, 4
people in the car passing someone, etc.) the
knock sensor registers light to moderate
detonation, which means I immediately get
out of the throttle, completely negating the
reason I got the miserable thing in the first
place. The head tech at KB was very
defensive of the tranny problem when we
called him, blaming it on Chrysler (has to do
with the computer taking the tranny from open
loop to closed loop whenever it senses boost
- this makes the truck act like it is at WOT,
causing immediate downshifting and
preventing upshifting until the load is
removed). This may be the truth, but since it
isn't something they warn buyers of when
advertising their S/C to 4.7 owners, the
responsibility for this falls squarely on their
shoulders. Since their kit comes with a KB
computer, I'm at a loss as to why they can't
find a way around this problem .
And the detonation problem...god, if you can't
get into boost (and I'm a loooong way from
flooring the pedal) reliably, the whole thing is a
very expensive boat anchor.
Perhaps you or someone else who's done a
4.7 install might have a suggestion to clear up
the detonation problem. At least then I'd have
the power I paid for, even though I've turned
my truck into a semi-automatic foot-shifted
model. Appreciate any help you can give.

Art - At this point I haven't done anything except
whine about the problem. I drive several
different vehicles, including a 1999 Buick
Regal GS w/ the 3800 s/c motor (sweeeet!)
and a 1987 Buick Regal Limited T with a
totally rad turbo setup. My time with my Dakota
has been limited, and it's only been recently
that I've driven it enough to conclude the KB kit
is not engineered very well, in my opinion.
Where would I go to get the PCM reflashed?
KB? Aftermarket? I'm thinking of adding
alchohol injection from either SMC or Jay
Carter (used extensively by turbo Buick
fanatics) to try to quench detonation, but it
makes me angry that at a reported 6lbs of
boost I'm having this problem at all. My Regal
GS runs 9lbs using an undersized pulley
w/out an intercooler and has never knocked.
My turbo Regal can run 18 lbs w/out knocking
with a large intercooler. My last pet peeve with
this kit is the absence of a boost gauge (I
ordered one from KB since they are available
at additional cost, but at 4k for the kit, this is a
bit much).
I just discovered yesterday that KB makes a
device called the Boost-a-Pump that
increases the voltage to the fuel pump, and
thus the fuel flow. I haven't gone back to the kit
documentation to see if this or something
similar has already been incorporated. I hope
it has, although the boost-a-pump on the KB
distributor's site shows an in-cab control
which I don't have. Anyway, this might be a
solution too.
I guess I don't understand why KB would sell
this kit with these problems unresolved. This
is a premium supercharger, and those of us
who buy it do so because we believe it is the
best and are willing to pay for it. I don't like
being surprised by issues that I think should
have been resolved before they released this
kit into the market.
In fairness, if someone knows something the
installers may have done incorrectly w/ this kit
to cause these problems, let me know. The
dealer's mechanics did a superb install job
though - it looks like a factory option, not an
aftermarket add-on. Thanks for the input, Art.

thank you all for the replies. I remember now that in an article by RD or Motortrend spoke of KB having problems with the shift points on the Jeep GC. Now I fully understand, I feel sorry that you had to endure such headache and pains with the S/C but thank you from me and most fellow Dak owners for enlightening us since many of us probably intend on purchasing an S/C in the future.

Joe,
Thanks for your info. Now I know the problem isn't just my truck or my installer. The Boost-a-Pump from KB doesn't come with the $4000 kit. It is actually an in-line pump that installs on the existing fuel line between the gas tank and the intake. I don't know if it would help the detonation problem, but I didn't buy it. I use Mobil or Amoco 93 and also pour in a bottle of N.O.S. Octane Boost every fill up. Luckily I haven't had the detonation problems. My installer has done many KB installs before and said the new KB computer takes care of the new timing, fuel curves, ect. He also called KB and the KB tech said they had no other reports of shifting problems with the kit so it wasn't their problem.
Good luck with your problems. Let me know if you find out anything more and I'll do the same.
THX,
Mike

I also have the 4.7 auto with the Kenne Bell. I have none of these problems you guys are talking about. I agree there is a certain spot in the throttle that you have to avoid. Get a boost gauge and you will see what i mean. The problems you are having is when you are applying JUST enough gas to ingage the charger. Your foating between boost and vacumm and this causes you to downshift....... auto trannies downshift due to torque load..... ingage the charger and it downshifts........ Also...look at the back of your motors..... notice a couple extra injectors??? The kenne bell kit includes them therefore no need for the Boost a pump(running on 6lbs anyway). Also, what is the stock compression on the old buick's, the 4.7 is like 9.5:1 (Not exact on that one) but that's a pretty high compression motor to start with. Add a charger and the obvious happens. Run the highest octane fuel you can find.... the alky/water injection is a good idea as well just incase you want to eventually run more boost. You will have the same detonation problems with any charger you throw on the 4.7!!!! Just the kenne bell kits comes with the detonation PROTECTION system that retards timing and all that, and lets you know there is detonation occuring. Other chargers just let it ping away. I will agree that the kenne bell tech's are pretty much useless though, i had a few problems after the install but all is well now........ no thanks to the boys a kenne! just my 5 cents.

I think your problem can be 1 of 3 things you are running the motor too hot... too much Boost. too low Octaine.. add a can of Nos to your fuel tank. and loose the 195* thermostat if still installed.and send your PCM into Keene Bell for a re-Flash as the dealer cannot program it the proper way for the Supercharger.

To get the boost from the KB SC our local shop uses an added alcohol injection system. Instead of 80hp gains with spark knock retard...you can get about 110.

No way man. Gotz to keep the thread going. They don't make a KB charger for the 4.7 anymore. KB told me it was because they couldn't get the "Optimizer" anymore. I've dealt with them in the past with my Mustang blower and they're as good as talking to a bunch of highschool kids. What really transpired is that they had problems and they don't want to step up to the plate. I continue to have issues to this day with my 94 stang meeting the promises that were shoveled out to me about the advantages of a non-intercooled positive displacement blowers.
Anyway. No more positive displacement blowers on n/a cars for me. Too many problems. Does anybody know anything about the Paxton kit?

Yes, you definitely revived a relic buried deep in the archives.
The 4.7 kits come with the Novi-1000 head unit which in out of the box form makes 7psi on the top end. They manage fuel with the Split Sec FTC-1 box and add to that 2-42lb/hr auxillary injectors.
I can only speak of my experience with the kit, but out of the box the kit added 103RWHP and 75RWTQ, and respectively dropped 1/4 times on the previous "Stock" best of 15.3 @ 88mph to 14.00 @ 99mph. With only minor changes: 3.20" pulley (about 9-10psi) true dual exhaust, and a home ported 65MM Throttle body, the truck jumped from 304RWHP and 351RWTQ to 350RWHP and 375RWTQ. The truck ran a best in that condition 13.08 @ 104.8mph.
The kits are decent, but if you want to make serious power, you'll need to ditch the Split Sec box and go with a custom PCM, FMU or stand alone and some fatter injectors. If you go over 10psi I would seriously recommend forged pistons and rods.
Overall... The kit is awesome. Great power out of the box and every mod added afterwards responded nicely.
