Thought I would chronicle my attempts at mods on my Magnum here. It is a 2008 Dodge Magnum SXT with 6 cyl 3.5L engine and 4 speed automatic. It has a Touring suspension from the factory. This gave it 18" rims and rear anti-roll bar. Actually a Canada build and someone swapped the cluster for a MPH one.

before picture:

1. I started with the free ones. Removed the snorkel/muffler on the intake Air silencer removal

2. Next I redirected cold air toward the remaining intake from the radiator. XE Ryder's Chilly air intake mod

3. I undid the Blinker Modification! I read a thread that this may cause feedback for the rear tail lights and thus a problem for trailer wiring. See for problems : Blinker mod side effect??? Possible solution for about $30:MY alternative to the blinker mod...

4. Got a second antenna and modified the old antenna to bend down for a cargo box. http://www.custommagnums.com/forums/audio-video/84898-making-radio-antenna-curve-down.html
AntennaSealed_zpse1310073.JPG

5. A new set of shocks/struts to replace the warn out ones. These were adjustable height. I got BC Racing coilovers. So I ended up dropping it about 1".

6. Tuner: DiabloSport inTune and changed it to the 93 octane tune. Yes it is a more expensive fuel but the engine requires 89 octane. I have a Costco nearby so no 89 there but 93. The 93 is cheaper than the 89 at other gas stations so why not. :drive:

7. With the BC Racing coilover install I also needed to quiet down the front suspension. New Mopar lower control arms, SPC adjustable upper control arms, and new outer tie rod ends. http://www.custommagnums.com/forums/suspension-forum/83938-front-suspension-self-diagnosis-results.html?highlight=

8. Rear load leveling air bags: rear Air Lift Air Spring kit


9. Got a "hidden" hitch. One of the original Mopars. That is now installed. Magnum hidden hitch

10. Grill block has been built. Details here.


11. Needed to finally tow with the hitch and picked up a few parts to get it all set. First the 90 degree adapter Mopar 82213549. Next needed something to raise up the 2" ball to proper height (18"?). Went to AutoZone and got Reese Towpower Adjustable Ball Mount (21141 or 70313) and a 2" ball (Reese 70083). bigjim in the "Magnum hidden hitch" thread ,Magnum hidden hitch - Page 4, welded a similar assembly together to eliminate play from all the joints. Probably a good idea but I don't tow much and plan to use a hitch mounted bike rack.

12. Wiring kit for Trailer installed (82209473AB 4-way). http://moparcarparts.com/instructions/82209473.pdf Want to go Mopar due to posts I've seen of aftermarket ones catching on fire. They are mounted inside the back so that can get really bad quick.

13. Big Bully 3.5L CAI intake. Finally got this. My stock intake broke a clip which allowed me to buy it. :drive:


Current image:


14. Fixed the recirculate door to fresh air. Door moving post keeps breaking so now I don't need to think about it.

Thank all.

Winter is hard to get good pics. Really the only visible one is the grill block and lowering. Follow the link to the grill block thread. Hmm. I suppose I could add a teaser image for some of them...

pics added per your request. I will try to get a side shot again after a wash to show the current suspension height.

Added details on the Mopar "hidden" hitch and parts to get ready to tow.

Ordered a Big Bully CAI today. Checked the oil and one of the front clips was broke on the stock air box. Not sure how long that has been broke. At most a couple of weeks. I'm guessing. I was waiting on a sale from 3GCustoms but I'm not spending $150 for the stock assembly to fix it. Also got a spare filter so one can be cleaned and oiled while still able to drive the car. Hoping it comes quick.

by removing the "Air Silencer" what exactly does that do?
My experience: Helps the engine breathe giving better throttle response, a _little_ bit more power, and better sound.

Gotcha. I may have to add this to my list of projects for my Mag this Summer. I will most like to this whenever I upgrade my fogs. Right now I'm waiting to address my "hyper" flash problem. I have load resistors on my rear turn signals, however they are only 25W. after doing some research I was told I would need resistors w/ 50W. Hopefully, they will be here tomorrow.

I love these threads, I started one when I saw TRUCKZILLA build thread.
Looks good, but one Question.
Curious, Why a grill block? What is the purpose? Increased temps, more fan usage?? Is it just so cold where you are?

Cold is part of it. The other is aerodynamics = fuel efficiency. So warm up was helped a lot in 20 degrees or less. From about 4 mile to full temps down to 2 or 2.5 miles. That means I can crank up the heat that much sooner. :)

Also with the huge grill blocked the air is not captured and driven into the engine compartment. Lots of drag that way. The air then has to go up and over the car. If you ever watch NASCAR racing they talk about front end tape. They block those grills as much as possible and peal off a little bit of tape to keep the engine from overheating. Our grill is big enough to cool the engine with 100+ degree outside temperatures. I very rarely have that in MI.

I have taken it off. Did that about a 1 month ago. This kind of mod needs lots of attention to engine temps though. You can't just put one on then ignore the engine temps. My wife drives this occasionally so I didn't want her to have to worry about it.


Still waiting on the Big Bully intake. :) Trying to get a idea of my wait time but 3GCustoms have not gotten back with with me. Getting a bit concerned. :paranoid:

Looks like I need to do the trailer wiring install. My dad's trailer is as wide as the Magnum and the tail lights are hidden. Ordered the Mopar kit. Found a thread on doing the 7-pin install:Installing a 7-pin trailer wiring harness Should be similar and unfortunately the pictures are gone. I'm a little concerned drilling into the body though. I need to go to Lowes to find the right size hole saw.

Undid the blinker mod today. Still waiting on the Big Bully intake and waiting on Mopar 4-way trailer wiring. Should have the wiring on Monday. Hole saw has been acquired. Just need a nice day to do it next week.

I installed the Mopar 4-way trailer wiring kit last weekend.

Finally got the Big Bully intake I wanted.






Sorry for the dirty engine pictures. Raining last night and with my intake broke I wanted it in right away.

I had a lot of fun removing and inserting the air temp sensor. Ended up putting a socket over it to push it out and a chunk of cardboard over the connecter to get it into the new intake. Waiting on a tank to be used up before I go from the stock tune back to the Diablo tune. :049:

Back to the 93 oct tune. Very nice with the Big Bully. I feel like there is a difference, especially kicking it in while passing another car. Whoot!

Got the catch can from BigBully last week. Over the weekend I installed it with my Dad. It is simple enough but always good to involve him in little projects. Looks great and I will see what it catches in a few months.

One more project to go: R/T brakes.

Here is a photo of the BigBully catch can installed: It is definitely doing it's job. It's top section is filled with metal mesh and the bottom catches the oil.

So when I got this Magnum I had to repair the recirculate door. I had to tear into the dash again today.

The last couple of days, with the 10 degree temps, the windshield was fogging up. Needed to have the defrost blasting. That is what happens when outside air is not brought in. Too much moisture. I removed the glove box to have a look at the flapper. Turned the key so the door should flip back and pull outside air. No movement. So I pulled the blower motor and reached up and felt the door. No resistance to moving between the positions. Great. My fix. I put the door down so you could see it from the glove box opening. This is the outside air position. I drilled a small hole through the hex opening into the door and put a small drywall screw into the door. It is now permanently in outside air. Being in Michigan it is rare that I use the recirculate air setting. Not a big deal.

If you want to repair this take a look at the link below. This gives details on how to diagnose/fix/replace the flapper door. Good luck.
