The instructions from Whipple talk about this on the back page.

"At idle, you may hear a medium-pitch rattle from the supercharger main housing. This will diminish at about 400-500 rpm above idle.

You may also experience a muffled high-pitched whine during acceleration. This is caused by the pumping action of the supercharger compressing air and only occurs during boost conditions. It is inaudible during part-throttle acceleration.

These are normal noises associated with any supercharger and have no effect on supercharger performance or engine durability.

NOTE: Whipple Superchargers will not authorize any warranty repair work or supercharger replacement for normal noise."

The chatter is completely normal. Yours does seem louder but I can't be 100% sure if that's just the quality of your video or what. I'm willing to bet the AC affects it because the AC clutch is engaging, raising engine RPM, and putting more load on the belt and blower.
Yeah I just read that after I posted. Thanks! And thanks for your thread. Help me a lot during my install. The problems I encountered were:

1) I unfortunately was sent a lot of 6.4L pieces and they setup my mani for the 6.4L. I had to be sent the -6an quick disconnect for the passenger-side S/C inlet and the bypass makeup hose for a 5.7L. That way I could connect the bypass actuator to the passenger-side S/C inlet by wrapping it underneath the S/C nose. They also had to send me a plug to replace the barb fitting they put on the driver-side of the mani that was setup to be used for the bypass connection for a 6/4L.
2) For some odd reason my EVAP solenoid was not located near the driverside strut. Instead it was mounted on the driver-side of the stock intake manifold. This made it to where the 90 deg quick connect hose wouldn't work as my EVAP solenoid connected via a plastic barb fitting. Really weird as I could not reference my particular EVAP solenoid in any MOPAR sites or literature. I ended up just hooking up a silicone intake hose from the barb on the EVAP solenoid to the top quick connect fitting on the driver-side S/C inlet.
3) The passenger-side I/C hose that connected to the I/C reservoir got in the way of the stock foglight on that side. Luckily since they gave me the I/C hoses for a 6.4L I ended up cutting it giving me a 90 degree extension heater hose and connected that to the supplied I/C hose with a plastic heater hose coupler. Made it so that all the heater hoses on that side "U'ed" around the foglight. Pretty proud of that slick work.
4) The throttle e-sensor extension they sent had a "6-pack" looking connector harness and my throttle e-sensor had a "linear" looking connector harness. I ended up hacking up the harness they gave me and soldered the connections in myself.

Overall compared to other platforms I have worked on this kit was a bolt on as it gets. Also great service from Whipple!!!

Do you have a boost gauge or a/f gauge? If so how did you mount it and pics?

Bryali is and has been a wealth of knowledge for me...Whipple confirmed that they have 3 employees with 5.7 Hemi's that all do the same thing. NO cause for concern!

That's where it is on my '14 GC 5.7L .. which is why my 392-style coil covers are still in the box.. haven't had the time to figure out how to relocate it..

I forgot to mention on here that I called Whipple and asked about spraying meth though the blower.

They have not tested it themselves but they have plenty of dealers/installers in their authorized network that have done it to customers' cars.

The guy I talked to said he has never seen a blower come back for warranty repairs due to methanol.

That's as close to an endorsement-free endorsement that we're going to get so:

SPRAY AWAY!!

First off - I have to say that this is an awesome thread, it has a lot of info and has really energized the thought of doing this to my '13 Durango RT. I did a lot of mechanical work in my teenage years (on the street in the city) and high power mods like superchargers were always a dream. The money, tools, and safe place to work prevented it from becoming reality. Maybe not for long....

I have a couple of questions for the group - hopefully others have experience with these things and can provide some insight:

1. If this is done to my RT, it won't be for 1/4 mile racing or anything like that, it's more just for the thrill of a lot more power here and there, as well as the satisfaction of executing the mod. Is there any reason to expect that a middle aged engine (60K Miles) would not be able to handle this for an extended period of time, or is it too much? I would hate to do all this work then find it needs bearings, rings or whatever else.

2. There wasn't a lot of talk about the tuning. After the SC is installed do I have to do the dyno tuning, etc or is there a "standard" update to the ECM that is good enough? I was reading about the black smoke and hesitation issues. Is that because you are trying to squeeze out every last HP? What's it like with the "stock" mod - does it usually run well right afterwards without too much tweaking?

3. What other mods are absolutely necessary when doing this? For example do you have to change exhaust, coils, fuel injectors etc, or is all of that only if you want even more power?

4. Anyone have any long-term data on how the transmission does with all of this? Assuming no drag racing, etc it should be fine right? Especially if the transmission is meant for towing, correct?

5. Any issues with motor or transmission mounts from the added power?

Basically my goal is to install the SC, do some tweaks here and there to get it running right, then have the truck for another few years as a daily driver without having to do too much else in the way of added maintenance or repairs.

Thanks, I try to be helpful. I hope you get to do something like this because (when it works) it's awesome! lol

I'll try to answer each of these individually.

1. If this is done to my RT, it won't be for 1/4 mile racing or anything like that, it's more just for the thrill of a lot more power here and there, as well as the satisfaction of executing the mod. Is there any reason to expect that a middle aged engine (60K Miles) would not be able to handle this for an extended period of time, or is it too much?

I won't promise that everything will go smooth. I can tell you that Whipple has designed their kit to pull out of the box, install on a stock 5.7L Durango, and add some 160HP at the wheels. The rule is that when you start asking for more than stock performance from a stock engine/transmission/drivetain/etc, you are GOING to find the next weakest link. If you've neglected your preventive maintenance then that will probably happen sooner than later. However, I've known people that have waited until they pass 100k miles before boosting their Hemi. I wouldn't be concerned about 60k miles but I also started spraying nitrous on a 135k mile 6.1 and now my lifters are ticking. Rather than stop spraying, I'm getting ready to rebuild my heads so I can keep racing.

2. There wasn't a lot of talk about the tuning. After the SC is installed do I have to do the dyno tuning, etc or is there a "standard" update to the ECM that is good enough? I was reading about the black smoke and hesitation issues. Is that because you are trying to squeeze out every last HP? What's it like with the "stock" mod - does it usually run well right afterwards without too much tweaking?
I honestly don't know if any of us that have Whipple'd our Durango have done it on a 100% completely stock vehicle. However, tuning is absolutely necessary. The kit comes with a canned SCT tune designed by Whipple. In fact, since you don't plan on trying to get max power, I would HIGHLY recommend you run the canned SCT tune and forget about it. Not many people support custom SCT tuning anyway so you should be able to tune it and forget it. My black smoke and hesitation came from poorly written tunes. I was able to get on the dyno with someone that cleared that right up. I was running too rich, like I tried telling the 3 other tuners before, but only the last guy believed me (and my wideband O2). I've had other issues that I think can be tied to a stuck PCV valve

3. What other mods are absolutely necessary when doing this? For example do you have to change exhaust, coils, fuel injectors etc, or is all of that only if you want even more power?
The only mod thats are absolutely necessary will come with the kit. You'll get new injectors, a fuel pump booster, and spark plugs with the kit. You can run your factory exhaust and aftermarket coils are a waste of money--if you don't believe me, there are people pushing over 1000 hp on factory Mopar coils. The only thing not provided in the kit is premium fuel and that is NOT OPTIONAL!!

4. Anyone have any long-term data on how the transmission does with all of this? Assuming no drag racing, etc it should be fine right? Especially if the transmission is meant for towing, correct?
My transmission is holding up just fine so far. Keep an eye on your transmission temps, especially if you are towing. Mine don't get up much higher than 195 or so when I'm towing. In the summer I would occasionally see it break 200 but not by much and not for long. I'm sure its life is limited in some degree but I can't say by how much. Also, before it gets brought up, NO!! the 8HP90 from the Hellcat will not bolt-in in place of the 8HP70. The HP90 is longer to account for the additional steels and friction bands that give the HP90 its torque holding capacity. You will require a built HP70 if you want something better than stock.

5. Any issues with motor or transmission mounts from the added power?
Nope, nothing yet.

Basically my goal is to install the SC, do some tweaks here and there to get it running right, then have the truck for another few years as a daily driver without having to do too much else in the way of added maintenance or repairs.
Like I said, if you want to install it and forget it, the Whipple kit has very detailed instructions and is not a hard install. Run the canned SCT tune and you will probably avoid all/most of these issues that most of us have been having with trying to get a custom tune for max power with additional mods.

Hope that helps and good luck!
 
On a '13 I think you have the W5A580 transmission, which I *think* is what the '11-'13 JGC SRT had.

I admit I have not really been following the the JGC-SRT transmission stuff too much, because when I do I want to go buy something I should not buy.

Doh! I missed that this was a 13.
 
I think the W5A580 is a pretty strong trans, but certainly different.

one of the major Durango issues is that each generation looks the same "on the outside" .. don't get me started about the different Gen-I headlight/foglight wiring :(

It is more important to get the info into a thread than to worry about whether it applies to the specific vehicle: someone will hop in and point out the differences .. 'cuz that's how we roll here ;)

I think the hemi's got the 65RFE, while the v6's got the w5a580

Yes, you are correct.. Brain fart on my part.

The 65RFE is a bit low on torque rating; that's why it wasn't used behind the 6.4L in the GC SRT.

I do t understand why they didn't just use the w5a580 with both v6 and hemi... they used it in the chargers, magnums, and 300 for the hemi's. And I the gear ratio spread of 3.595 to 2.186 1st to 2nd seems a little better than the 545rfe/65rfe's 3.00 to 1.67 1st to 2nd, or I'm thinking totally backwards here...
 
so to wrap all this up ... is the whipple SC reliable, and can be installed relatively easily with no major modifications ? can the vehicle be easily properly tuned by an experienced shop ? any caveats to doing this mod ? im seriously considering a whipple.
 
Hi all, new member and DD owner.

This thread kept me up so many nights... Good stuff - thanks to Bryali for being a pioneer! I blame him for the new blackhole in my bank account!

I bought a 16 DD RT back in June of 16 because of this thread, with the intention of slapping a whipple on it. I was looking at SRT Jeeps, but I needed more people hauling capacity (kids), so DD it was. a DD plus a whipple is still less than an SRT jeep... grant it, it's not 100% built for the power (brakes, engine bottom end, etc). In any event I've never had a stock vehicle in my life - tinkering is a hobby for me...which sometimes gets expensive...

The car was solid stock, but dare I say that it sounded meaner than it really was - still very respectable and enough performance to put a grin on a guys face while still being able to haul the child-army around town...

After wife-sponsorship was obtained I took my truck in to LMT in Waukesha Wisconsin and they did the install for me. I'm a car guy and amateur mechanic, which is to say I have the right tools and guts to get things done right and have modified (for better or for worse) every vehicle I've owned. I haven't had a naturally aspirated car since 1997...That being said, Whipple does not have a canned tune for the 2016's yet, so I still needed a custom tune. So I figured I'd take a back seat on this one and let the pros get their hands dirty.

Anyways, they dyno tuned it and I just got it back - so I thought I would contribute to this great collection of information...

My truck "stock" (I put a mopar CAI on it) came in at 293whp when they baselined it. They ripped all of that off and installed the whipple and tuned it for 93oct fuel and pulled an astonishing 505whp out of it. No other mods. +212whp gain from one bolt on - that's pretty unreal.

The tune was custom, but started with an HP Tuners baseline.

No Transmission tune seems to exist yet - which seems like a must have at this power level. I am positively hitting the torque limiter at WOT and it's backing the ECU down, causing some stuttering and wavy power. For now I just keep it under 65% throttle input. The smiles still happen and the truck MOVES. I'm sure I'll make a run down to Great Lakes this spring and get some 1/4 mile numbers. Until then, I'm just really enjoying the added low end torque and the feeling of effortless acceleration.

Welcome and congrats!

I'm also having some issues with getting full power out of this thing. We have to hold at about that 3/4 throttle or the transmission drops into limp mode....or at least what I assume is limp mode because it's very similar to the 5spd when it overspeeds.

There is no tuning for the transmission YET but I'm looking towards a Paramount Performance built 8spd and a converter in my future. Even without dedicated transmission tuning, Bill is able to program the TCM which is built into the 8spd valve body to make it streetable AND handle the extra power.

I'm sure with the canned Whipple tune these issues wouldn't be popping up. I'm also sure the canned Whipple tune wouldn't be putting out the power that a custom tune is. I'm able to daily drive it and get a smile every time I step on the gas.....I just have to watch my redline because it comes up QUICK!! LOL

Hands down... with my 15, using the paddle shifter cuts out the annoyance of the automatic 8speed - factoring the whipple and etc. I believe HP is the works of making the trans tunable eventually.

I want to find a solution of moving the paddle shifters to 8-4 position rather than 10-2.

Sounds like what is needed is the 392 Scatpack/SRT HP70 trans tune...they shift much faster and sharper.
From what I hear, the 8spd cars have trans tuning but the trucks and SUVs don't. Something about it won't cross over. Bill (from Paramount) says his testing on his Jeep is coming out amazing.

For the Durango we will be limited (for now) to one of his built transmissions and we can't do just the valve body because we don't have the track mode and launch control stuff. His built transmissions will address line pressures for shifting response and firmness. It will also hold the increased power that some of us are making.....especially when combined with a new converter.

I'm not exactly sure how our vehicles will respond in Eco Mode On/Off but I'm hoping Eco On will shift "normal" and Eco Off will shift more aggressive for the track. Kinda like a sport mode On/Off except our button says "Eco Mode".

I also don't know how a new converter will respond without tuning. If the converter is trying to flash to 3600 (for example) but the stock trans tuning is trying to lock up at 1800 (again, for example) then I see some serious problems in the transmission's future.

I don't know any of these things but I'm hoping to find out in the next year or so.

My tuner completely disabled my eco mode.
Yeah, but it'd be nice if that switch provided similar functionality to the street/track modes that the Jeeps enjoy. Literally having two good driving styles available at the push of a button rather than one good and one blah.
