The very first thing you need to do in order to install a Whipple supercharger on your 1yr old family SUV is marry someone awesome. I did that!

The next things you need to do are 1) buy the sweetest SUV on the market and 2) buy what I consider to be the best designed supercharger on the market. Check and check!

OK, so seriously, let's get down to business. I am going to assume that anyone attempting this understand what the basic parts of the engine are and can identify most tools. If I have to explain step-by-step how to remove spark plugs because you don't know where they are located and you don't know what a spark plug is, then you don't need to be doing this yourself.

The kit came shipped in 2 very large boxes that were well packaged. One box holds the supercharger and the other holds all the other "stuff" for the install.



The other box (sorry, no picture), has the air filter and intake, bracket, pulleys, wiring harnesses and extensions, MSD fuel pump booster, spark plugs, belt, heat exchanger, hoses, several bags of bolts and random hardware, the instruction booklet, stickers, and a license plate frame. What it does not include, but you WILL need is the following:

--Coolant--Mopar or Zerex G-05 only. DO NOT USE "ANY MAKE OR MODEL", no matter what the "expert" behind the counter tells you. I found the G-05 at O'Reilly for about $19 hidden under something else. The dealership usually wants about $30. It probably won't be on the display wall with all the "any make or model" stuff so ask for it. Tell them it's "the Mercedes stuff" and then usually 1 person will dig in the back and find it. You'll need to dilute it with distilled water and you can get that for $1 or less at your local Wal-Mart. DO NOT USE tap water, drinking water, spring water, or anything other than distilled water.

--Allen head sockets, 3/8" drive is fine and you'll want everything from about 4mm to 10mm. I bought a set that had 3, 4, 5, 6, 7, 8, and 10 and inevitably I needed a 9 so I had to get creative. Make sure you get them all. I cannot emphasize enough that you need to either have the right tools or invest in them. I also recommend torx and allen screwdriver type bits and the long t-handeled allen wrenches. There are some tricky places that the sockets won't reach so you will need 1 or the other.

--Sealants and chemicals. The instructions tell you to get a few Loctite's: Red 271, Green 648, and Blue 242. You'll also want anti-seize, teflon tape, and any "clear automotive grease". I couldn't figure out exactly what they meant so I recommend something like this Super Lube Silicone. Carb cleaner is helpful as a degreaser/cleaner.

--Shop towels and gloves to keep things clean. You WILL spill things so be prepared to clean up. We picked up a bag of clay cat litter and used black nitrile gloves and had 3 or 4 rolls of the blue shop towels floating around. Trust me, you'll make a mess with something so be ready to clean up. I also have fender protectors to protect the truck's paint. I had a box of zip-top baggies to label and collect parts as I took things off. Masking tape is helpful for labeling and for protecting the engine when the intake is off.

--A right angle or 90* drill--something like this. You will be required to drill into your crankshaft and balancer to "pin the crank". I chose to pull the radiator to use my impact wrench on the center crank bolt and a normal drill for the pinning and ended up busting one of the tubes in the radiator. Learn from my mistake and either buy one or rent it from your local hardware store. I would also do everything I could to figure out a way to break the balancer center bolt without having to take out the radiator. An air ratchet (or electric power wrench) would be another tool investment but it'd be worth it to not have to mess with a busted radiator.
--Nothing but 91 or better in the tank. I'd been running the canned 93 tune from Diablo so I had 93 in the tank and that's what I will continue to use. Don't think you'll be able to leave 89 in the tank and then drive up to the station and top it off with 91 or 93. I highly recommend you plan ahead and start running your intended fuel for 2 or 3 tanks before you start the install. If you plan to run 91, use the Diablo 91 tune with 91 gas, etc.

--If I think of anything else, I'll come back and add it.

Some of the parts in the kit are specific for the Jeep SRT and some are used for the Durango while some parts are used for either platform. Read through the instructions while you look at the part to get familiar with what goes where and when you will be using them. If you're missing something, this is the time to find out and not when you're up to your elbows in engine bay. I was sent the wrong spark plugs. The instructions called for either NGK 2315's or 4306's but mine was shipped with 5107's that are designed for the 6.4L SRT. All manufacturers have their own specific heat ranges but the stock NGK's are a 5. The 2315's are a 6, which is actually 1 step colder despite the higher number. The 5107's are a 13--which is WAY too cold! Also, the 2009+ 5.7 Hemi has Eagle heads which use a gasketed spark plug but all of the recommended plugs are tapered. According to a few engine builders and tuners that I asked, it's not a big deal while you're running them, but once you go to a tapered plug you CANNOT go back to a gasketed plug: remember that if you ever plan to go back to stock.

Now that you've read through the instructions, start taking things apart.

Jack the truck up and pull the wheels off. The instructions say to do all 4 corners but 2 of my jack stands were being used on another car. The inner fender liners, fender trim or "flares", belly pan, and front bumper all come off.



Then the stock airbox, throttle body, and intake manifold all come off. You'll have to disconnect ALOT of things: the fuel line, vacuum lines, electrical connections, etc. Follow the instructions and use some common sense. If it's in the way, get it out of the way. Here it is with most of the stuff out of the way.



And here is EVERYTHING removed. Notice the heater tubes removed, the intake taped off, fuel line was secured and the heater core fittings are wrapped up with blue shop towels in the back.



The instructions call for disconnecting the (2) coil capacitor connectors from the back of the cylinder heads. I believe that is only a 6.1 or 6.4 feature. I had 2 plastic tabs that secure the wire harnesses instead. Either way, common sense says that if it's in the way, remove it. Next is time to pin the crank. The instructions show a 90* drill in the pictures for pinning the crank but I figured it would be easy enough to pull the fans (in the instructions) and the radiator (NOT in the instructions) and using the electric impact and drill I already have. I figured I could get it out and back in without damaging anything. Nope...not so much....and it's been a rather expensive and stressful lesson. Seriously....if you can afford a supercharger, you can afford $200-$300 to buy a 90* drill and an electric wrench to pin the crank without pulling the radiator.

The instructions also don't say anything about replacing the spark plugs until much later....after you've already installed the lower portion of the intake manifold with the intercooler built in. I chose to do it now, after all the removal was done and before anything new was installed. That's where we were when I posted this picture the other day:

Next it was time to start putting things in, which is also about the time pictures really slowed down. I started to see some progress and the already-scarce pictures turned into, "hang on, let's just do this next step and then we'll stop for pictures."

The intercooler tank and pump was a little tight to get everything hooked up behind the passenger side headlight and bumper. It comes with a bracket that positions the coolant tank and fuel booster pump but once it's up under the truck, it's kinda difficult to get to some of the connections. I didn't get any pictures of that but the instructions and a little common sense are good enough. The instructions for relocating the horns on the Durango are not very clear and the provided "relocation brackets" weren't very intuitive--they were just flat pieces of metal and even the PDF pictures weren't very detailed. We ended up following the instructions for the Jeep and put them in this general area:



The intake manifold is set up in 2 pieces. The lower pan and the upper part that contains the intercooler. This picture shows both halves installed, the new thermostat housing is installed, and the intercooler filler neck is between the passenger side head and the fuse block.



There are 2 allen head or socket head cap screws (SHCS) that sit down inside the bypass area. The bypass area is inside the circle with the brown gasket just behind the shadow of the electrical connector. This is an area where air passes when boost is not building, such as at idle, so it bypasses the compressor and intercooler. Yes...they sit down inside there and they are accessed by the holes that are highlighted in red. This is one of those areas that long t-handled allen wrenches would be helpful. Magnetic would be even better so you don't have to worry about dropping the screw once it's down in there. Also in this picture, the Whipple catch can has been removed from the oil filler neck and the stock oil cap was put in its place just for clearance during the install.



Finally, the blower goes on top of the intake manifold. This thing is the heaviest part of the whole assembly so have someone to help. The back 2 screw holes are slotted so you can start the screws in the intake manifold and then use those to guide the blower into place. We posed for this picture....it's not light enough that we could handle it like this and still be turned around for a picture. We told my oldest son that we would hold it in place and smile for the camera but about halfway through lifting it into place we realized we couldn't hold the pose so we set it down and then turned around, lol.



The instructions were very specific on so many things, but it never said "connect the supplied Whipple fuel line to the factory fuel supply line". I decided to wait until the very end and I was ready to prime the fuel pump just in case I had to disconnect something and I didn't want fuel spilling.

Right before the compressor are 3 vacuum ports. There is also 1 port on the passenger side that I plugged up with a supplied pipe plug, even though the instructions weren't very clear on this. The instructions also weren't very detailed with the 3 ports on the driver's side but as best as I can tell, they should be connected like this:

--Top is the smaller of the 3 fittings and connects to the EVAP Purge canister
--Middle connects to the catch can that sits on top of the oil fill port. The hose coming off the back of the catch can wraps around the engine and connects to a supplied PCV valve that screws into the intake manifold between cylinders 6 and 8.
--Bottom connects to the brake booster



Here you can see the vacuum ports connected and the exciting satisfaction of removing the sticker that says "remove".



The bottom of the catch can (still not pictured) has yet one more vacuum port (visible in the picture above) that uses a supplied hose to connect to the intake tube. The intake tube is short and has a built-in twist to line up properly. Once again, I didn't get pictures but the filter is absolutely HUGE! It's probably twice the size of the one that came with my LMI and it FILLS the area that the factory airbox once took up. I know it's necessary because of how much air this thing moves but that still didn't prepare me for just how big it is.

I hooked the battery charger up and let it sit for about an hour before turning the key on to prime the fuel rails and check for leaks. Then I installed the tune provided by Johan, turned the key (or rather pushed the button) and it fired up. The smoke in the video below is from coolant that was spilled when I was filling the intercooler.


After letting it run for about 2 minutes, we shut it down and checked for leaks and we found some coolant on the front side of the AC condenser right in front of where it had been leaking and I'd tried to repair it. At that point we put everything away for the night and started trying to figure out the quickest and easiest way to get the radiator repaired. Did I recommend to do anything you can to avoid pulling the radiator? In case I missed it, you should invest in any tools necessary to pin the crank without pulling the radiator. Seriously....

Reserved for the obligatory "holy sh*t, that's awesome" post



OK - Holy Sh*t, that's awesome.

Great writeup - If we ever get around to nominating posts of the year, this one is definitely up there!

It's impressive enough you knocked this out, but the ease with which you seemed to have approached it is even more amazing. Kudos.

Thanks everyone!

The radiator was delivered to the shop with a cracked side tank. They ordered a new one overnight and it should be getting there sometime right about now. The truck is still taken apart so that as soon as it gets delivered (and checked for cracks) it will get installed and I'll get a call. I'm hoping to know something after lunchtime.

After I pick it up, depending on what time that is, I'm going to go by the exhaust shop that welded up the 02 sensor bung and have them install the actual sensor since the guy decided to put it in a place that I can't get to it. He also welded it on the underside of the exhaust so it won't be long before the sensor is no good--but maybe I'll just use that as an excuse to upgrade to a set of catless longtubes!!
