Finnaly found a site with some dyno numbers on a stock 4.7 with a paxton bolted on.
http://www.metropartsmarket.com/catalogs/image_performance_52858.html
37% increase with the stock exhaust and that horrible cat on there. Thats still 315hp. Now if I can get 40% more out of mine. Lets say 260hp+40%=365hp, conservitive guess. Not bad for a 287 engine.

Long read but it has some rear wheel hp and tq #s
When Paxton Automotive set out to modify and refine its project 2000 Dodge Durango, it had one goal in mind: to enhance the performance of the Durango without sacrificing its driveability or luxury amenities. After testing out the black beauty that adorns these pages, we feel that Paxton has definitely achieved its goal.
Paxton used the Durango for four months to develop and test a supercharger system for the Dodge's 4.7L powerplant. Since Paxton Automotive's main business is developing and manufacturing superchargers for the automotive market, the company had a keen interest in creating the right package for the Durango. The centerpiece of the supercharger kit is Paxton's NOVI-1000 supercharger, one of the units in the company's line of NOVI geardriven superchargers.
The NOVI line of superchargers is based on Paxton's gear case, which features billet steel, helical-cut gears (3.54:1 step-up ratio), high-speed bearings, and direct engine oiling. The NOVI-1000 unit was designed to appeal to the enthusiast who wants an effective centrifugal supercharger in a compact package. The unit features a wide boost range that enables it to be used on four- and six-cylinder engines and small-displacement V-8 engines (in the case of the Durango). The NOVI-1000 typically offers a nearly 50 percent increase in rear-wheel horsepower over stock powerplants.
In conjunction with the supercharger, Paxton engineers also installed a Paxta-Map Fueler System and ignition timing control on the Durango. Basically, the system is boost activated and contains a programmable fuel curve that can manage as many as three additional injectors. The additional injectors can be mounted in the discharge tube of a supercharger application. The supplemental fuel system allows a consistent air/fuel ratio through varying levels of boost. As the boost is increased, more fuel is added. Providing more efficient elimination of exhaust gases is the addition of a MagnaFlow after-cat exhaust system, which also serves to throw a few extra ponies into the horsepower mix.
With these performance enhancers in place, the Durango was placed on a Mustang dynamometer for a series of test runs to determine horsepower improvements. Baseline testing, prior to the installation of the supercharger package, showed maximum rear-wheel horsepower at 209, with torque checking in at 255 lb-ft. After the installation of the supercharger kit and additional performance mods, horsepower figures jumped to 296, according to Paxton dyno figures, and maximum torque to 308 lb-ft -- a dramatic improvement over stock. Of course, what this means in the real world is the ability to handle larger towing loads, the power to pass lesser vehicles easily when conditions warrant, and the grunt necessary to cruise uphill without becoming bogged down.
With the performance mods completed on the Durango, Paxton turned its attention to some additional upgrades that would set the Dodge apart from the rest. Suspension upgrades are fairly extensive and include a set of Hotchkis Performance sway bars, Koni adjustable struts, and Hotchkis lowering springs. With a lower center of gravity and a stiffened suspension setup, the Durango's body roll and handling characteristics were noticeably improved. In addition, the Dodge's rolling stock was upgraded to stylish 18-inch Center Line wheels wrapped by Toyo rubber of the 265/55-R18 variety. A final stylish touch to the exterior was the addition of silver racing stripes over the top of the Durango.
Inside, the Durango benefits from the addition of a few aftermarket creature comforts. For the entertainment of backseat passengers, a fold-down Rosen video screen was installed in the headliner and receives cues from a Rosen DVD player and television tuner. Remote headsets are also provided for the passengers' viewing and listening pleasure. Lastly, an Auto Meter boost gauge was installed on the
A-pillar in the Durango's interior in order for the driver to keep track of the NOVI-1000's boost characteristics.
During a week-long loan of the vehicle, we came to appreciate and understand the Paxton Durango's many features and nuances. As we drove and tested the vehicle, one thing became readily apparent: The Durango, although performance modified and sporting an aftermarket suspension, offered excellent driveability and compliant ride quality and did not sacrifice any of its luxury amenity characteristics. However, when called upon to do so, the Durango had power in reserve to do the driver's bidding. We also noticed less lean and sway (as compared to a stock Durango) as a result of the suspension upgrades.
Paxton Automotive has a long history of developing supercharger applications for the automotive marketplace and more recently has been very active in creating supercharger packages for sport utility vehicles. Paxton has built a number of project vehicles, such as this Durango, to showcase its latest products; we'll be working with the company to bring these vehicles to the pages of Today's SUV.

Yes I saw that one but they had some mods into the 4.7 before they started. No auto 4.7 turns 209. More like 180-185 stock that is. I was looking for numbers to compare to a other stock engines with just a supercharger. It is a good artical though.

I'm not sure what else you're going to do to get 37% increase in hp and 19% increase in tq for $4500??
If you take a 231 rwhp truck like Matt Barret's and add the Paxton, that's making 317 rwhp. That means the motor is making 372 hp at the crank. The original 1969 440 6-pak cars made 390 hp at the crank, so I'm thinking that 372 hp from a 287 ci motor is pretty damn good.
Maybe that's just not enough bang for your buck, there.

The whole point was to find numbers on a stock 4.7. If you look around the 360 only makes 345 the 318 makes 309. The 4.7 stock makes 319 which is more power with the same type of supercharger than the bigger 318. Lots of people seem to want to spend 4000 for a 360 or 318 why not a 4.7. This is non intercooled and 50 state legal. Which could come into effect in the next few years.

The reason I am looking at a paxton instead of a turbo is because of a turbo spooling on a icy road and me going 60mph backwards down the road. Emissions testing scares me as well. If I spend 5000 on a turbo that is not emissions legal then they come up with testin in my area (doubtful) then I have a $5000 hair dryer.

my thinking as well. with the cam setup, and
some ported heads, you could be close to
350 rwhp. then your problem becomes how
to get that power to the ground? I dont think
my auto tranny will hold up to much more hp
than that.

C.W.,
Thanks for diggin that bit of info up....I saw the prior article in truckin SUV on the Durango. Wanted to see it on a Dak.
As for numbers we can all believe, I will be running the Paxton on the chassis dyno, after install is complete in the next few weeks. I will post the dyno for everyone that's curious to see. This will be me, not PAXTON or somebody trying to make money by selling the kits...So the numbers will be straight forward. The same for the 1/4 mile times.
As for the price on that web-site, those people must be crazy!
I purchased mine from Speed Tweaks for $3,700.00 that includes freight.
My truck is bone stock minus the single inlet, single outlet Flowmaster 40 series muffler...
My 1/4 mile times I expect won't show as much gain, during the hot summer months as say October. I have run in cooler weather 14.86@90mph, but the norm in the heat of summer is around 15.0-15.1 @ 89mph...
I will try to provide a helpful review of the supercharger, to those who are interested in the kit. I know $3,700 is a lot of money to drop on something to not know how it's going to perform.... Believe me, it was hard for me to drop it! But...Somebody has to be the guinea pig.

Peak numbers are not as telling as the area under the curve. At any rate, good luck to you with your new supercharger. I think you'll be pleased.

notchlx - Do you have to run 93 octane fuel with it? I would love a review! I'm not looking into one... just curious.
CW - from what I know turbos are good for small engines that build RPMs quickly, SCs are good for larger engines that have the TQ to turn them (like a truck). The downside to turbos is they run HOT since they use the exhaust side to make them turn. The spool-up time is not that bad... I had an Eclipse Turbo and currently my wife has VW Passat Turbo. The power was actually distributed nicely in both vehicles - maybe because they are factory systems, not sure - so this idea that turbos spin-up and *then* take off is not ture. Turbos also put out a good deal of low-end TQ, so once again the idea that you have to rev-up a turbo get power is wrong.
The downside to the SC is that it's running all the time, drawing power AWAY from the engine at low RPMs - it's like having the A/C on constantly. Where as the turbo only spins up when you get on the throttle, so under "normal" driving you do not even notice the car is turbo-charged - thus mileage does not suffer either. For example my '97 Eclipse GST got around 26 MPG and had 210HP and 214lbs of torque at like 2,100 RPM - the thing was a ROCKET. I could toast Mustangs with that little 4 banner rice burner :D

JMII ---that depends on what kind of
supercharger you get, the kenne bell setup is
only under boost, at certain RPM's. it actually
improves your overall gas mileage, if you dont
romp it all the time. the reason your wifes
passat doesnt take that long to spool up is
because of the size of the turbo, but if you
check, the turbo doesnt kick in until about
2000 RPM's. every turbo setup has turbo lag.
the nice thing about the supercharger is it is
instant boost. the only downside to the paxton
is that you have to tap the oilpan. the kenne
bell setup uses a self oiling design. I think
the paxton and turbo's are more for race
applications than the kenne bell setup. After
seeing the roots type supercharger on my
brothers tacoma, I dont think I would buy
anything else. and his setup is a single
screw type. the kenne bell is a twin screw
type.

They do put out good torque but the price is going to be more. At least from what I have heard. Also the non linear boost in low traction situations isn't a good thing. I love turbos but am unsure of the cost at the moment. $6000 cnd is alot for a paxton, never mind what the turbo will cost. If they have a way to adjust boost very easily and the cost isn't too much I may eventualy go that way.

Alex: At what boost level though? (Duner wasn't running no 6-7#.) Remember, a turbo will make more useable power than a centrifugal supercharger, at the same boost level, at any rpm.

CW- I would not think you would have a problem driving in the winter with a turbo on your truck.
Boost will only come on as your right foot demands. Load dependent.
Careful driving as required for adverse conditions would not spool the turbo.

You get the Powerdyne on yet?
When I get the Paxton on, we'll have to meet up in Mooresville.
I'm sure with your heads intake and cam, you are "ROLLIN" pretty good.

I may have mis-stated that figure. Let's say 400 hp at the wheels at 10 psi. Sure, you need race gas to get those numbers, but when you're at the track, that's pretty easy to accommodate.
Centrifugal superchargers may come up shorter than turbo's, but we are all suddenly finding out (in the past few days) that a person can buy TWO supercharger kits for the cost of ONE turbo kit.
Guess it's all a matter of how fast you want to go........

I have to get some pieces machined for my fuel rails/lines and install my return fuel system.
Then the boost begins!
Mooresville would be great. I'm also going to head to Bristol in the fall.
