unlock a few horses

ok so while workin on my buddies durango, it has a 5.2 V8, i noticed that the intake hat that goes onto the throttle body is like triple the size of the ones that come on the 5.2 AND 5.9 JGCs... i did however notcie that his is oriented the other way, meaning that his gets air from passenger side. and so the hat is switched to the pass side.. i have been doing research for about an hour and everyone on the durango and jeep sites say it 100% wont work on the ZJ.. so in a few days ill show you guys how i did it.. i think the added air to the TB would be benificial to something that cant get out of its way on the top end..

just an fyi.. at keystone a while back, me and my dad did some passes with various stupid mods you can do.. one of which was running a pass with the intake complete as it was from Jeep, then one pass with absolutely nothing going to the intake, completely removed, and gained just a hair over a tenth of a second..

and it also gives more room to relocate the air intake temp sensor..
this will be very detailed and have quite a few pics so.. lemme know whhat you guys think before i do.. no matter what i am gonna do it so..

Re: unlock a few horses

If you can find one on-line at an auction site, the Mopar Performance ECU works well. It will require you to run premium fuel, but the mid-rpm range power improvements are nice to have. CAI, ported TB, and 3" exhaust is the usual list for waking up these engines.

Re: unlock a few horses

oh i know, i have a full (headers back) 3inch, no cat, flowmaster exhaust, ported TB w/out air horns, no air filter (dont ask lol) 100 Shot of Nitrous, and i always run in AWD... no internal motor work done... i did stupid little stuff to the map sensor, crank sensor (which was a PITA), TPS sensor.. all little dumb things that may only have a total of a 5HP gain but hey they are free mods, which (hopefully tuesday when i dont have to work) is what this lil durango intake will be all about.. ill have pics dont worry...

and i havent been able to find a Mopar Performanve PCM for a 95 318 w/ auto + factory alarm to save my life... i am 95% sure that no one makes them anymore, but idk

Re: unlock a few horses

You should add a Air Filter...........Or you'll regret it.

Re: unlock a few horses

Contact Kolak@aol.com to ask about a lead on a Mopar ECU. If he doesn't have one on hand, he may know of someone that will part with it. When I got rid of my '94, I sold it to a JU member for $50 as I recall. I believe they were about $200 new.

Re: unlock a few horses

I have the SCT X-Calibrator or whatever for my Niner and it was $375, but that comes with a custom tune from a well-known tuner (HemiFever) and it also includes free "re-tunes" for life. So, I have the basic mods all done now. If I decide to do a cam and heads later, he'll re-tune it for free. Tune files can be e-mailed, too.

I know it's more expensive than the Mopar performance ecu but those things are getting rarer by the day. Some of us have to have instant gratification!

i just did full custom after the y pipe.
but on my Olds and Impala i just ran a simple peice of exhuast pipe from Napa... im pretty sure if u tell them what you are doing they'll frown upon or str8 up not sell it to you so... unless you dont have to do the e test then you should be fine...

as far as the Durango Air Hat... it was a success.. sry i havent updated it. i forgot i had the thread....

i have pics somewhere on my camera... the only thing you gotta do or buy is a piece of all thread or a long bolt... i had one layin around.

you have to,,, umm.. "persuade" your hood a lil bit to accomodate the intake after wards...
after that you need a longer piece of hose or a connector to reach the stock hose coming from the top piece of the air box.

the bolt is for the throttle body. the stock one does come off. you simply thread the new one on so its longer.

results are what is to be expected. its a lot louder. you can really hear the Magnum pullin in the air... its a mean rushing sound.. to compare it, remove the air hat from your Magnum and open the butterfly fully, thats what you hear...

i noticed a lil bit more grunt from the line.. nothing to brag about. but stock for stock, my Jeep with 32s, simple mods, against a stock (small tire) Jeep i beat him by a bumper... so it made up for having tires about 5 inches taller than stock on stock 3.73 gearing.

would i do it... Yes
i think i paid $3 for the complete Durango air box, filter, hat, spacer, and teh metal peice that they have over the throttle body. its a worthwhile mod if you have a few hours to destroy....


PS i promise as soon as i find the pics, ill post them...

Re: unlock a few horses

I got lucky, I had a guy give me a first gen K&N intake. It had a crack in it so I emailed K&N, they wanted pics of the crack and they sent me a gen 2 intake tube with all the hardware. So for about $20 in spray paint I got a new K&N intake.

Re: unlock a few horses

im about to get bashed hardcore for this im sure, but i have evidence, track tested, jeep tested, not some report from a multi million dollar company trying to double there profit from ppl like us, but:
i NEVER noticed anything from the K&N on my ZJ, so after borrowing one, i just put my stock ZJ box and tubes back on. i never liked the idea of having an open element in the engine bay anyway, but im mainly about performance, and when K&N advertised big gains with their system, i wanted one. i never thought about how they tested them though. on a dyno, with the hood OPEN and a ginourmous fan blolwing at the front of the truck. well...
a lil info about CAIs

and better yet

im not bashing K&N spectre or any other brand, i personally hate all of them and the only thing ill run of K&N are their oil filters for my Impala, Olds, and Saturn.

Wow, that's ballsy, lol.

Just kidding. I tend to agree with you. Especially if a CAI is the ONLY mod you do. Without the supporting mods to require increased airflow, you will see little (if any) gains with only a CAI. These little tuner douches crack me up. They are so convinced that this $250 intake is going to give them a 15 horsepower gain. Really? This little tube and washable element filter is going to boost your engine output by 10%? I don't think so.

However, one thing I do urge you to consider is that although they are called a "Cold Air Intake", I would say that the air temp of incoming air is of secondary concern with most of these. Many are not "true" cold air intakes in that they still suck in warm engine compartment air. Also, remember that since metal conducts heat better than plastic and rubber, many kits will actually give you an INCREASE in air temp over stock. Not all kits are made equal. In this regard, I feel that the K&N kit is a leg up on the competition. Plastic intake tube and a filter surround shroud that pulls MOST of the air from the grille of the vehicle (NOT through the radiator).

If you want a TRUE cold air intake, you gotta search for one. The CAI for my SRT8 actually goes down into the passenger side wheel well, like behind the passenger side fog light. PITA to install, but there are no questions on air temp for this one.

Another thing ppl tend to forget is that a "cold" air intake can't cool the air. You laugh at this statement but remember that the coldest air your engine can intake is ambient temp. I.e. if it is 80*F outside on a summer day, your engine is (at best) getting 80*F air incoming to it. Probably a tad higher. This is true, even if you have an intercooler. Unless you are running CO2 or ice in your air-to-water intercooler tank, the best you are going to do is ambient temp. Simple law of thermodynamics here.

Lastly, do remember that most of these CAI's are better than stock in that they offer LESS RESTRICTION to flow, not necessarily cooler air. The benefit you will see from this depends largely on how much of a restriction you were seeing before. If you have a lot of mods and lots of flow, an intake will help you. If you are bone stock, I'd have a hard time believing you are going to pick up the 16-17 hp that K&N advertises. In either case, you will have a less restrictive intake, but whether or not that restriction was causing you a hp loss is a different issue altogether.

Think of it like this - say you are filling your swimming pool with a garden hose. Takes a while, doesn't it? Now, if you replaced your 3/4" garden hose with a big, burly 4" hose, would it fill the pool any faster? No, it wouldn't. Sure, going to the 4" hose reduced the pressure drop, but was that pressure drop holding you back in the first place? No, not unless your garden hose is 2000 feet long.

Now, say you are filling your swimming pool up using a large water truck (the tractor trailer kind) that has a PTO-driven water pump on it. Do you think using a 4" hose instead of a 3/4" garden hose will help you in this case? Yes, it will, because pressure drop is a big concern in this example. But only because you have enough pressure and flow to have the 3/4" garden hose become your bottleneck.

To summarize, an intake WILL help if your ENGINE CAN HANDLE MORE AIR. If it is getting plenty of air as it is, it's probably not going to be the wisest $300 you've ever spent. An engine is a system, and a system is only as good as it's worst part. Making the rest of the system better won't help if you leave the worst part unchanged.
