I talked to Cliff at UMP last night and he brought me up to speed on where they are with the production model of the Superfilter air-box. The tooling for production is done and a small production run will be available in a week and a half to two weeks. For those of you interested in purchasing one of the first ones you may want to call UMP and check on availability. I will be receiving one of the first production models for review prior to purchase by someone in my area so I'll have pictures and a review of the production model prior to the market release in mid February.

I've had the pre-production model on my truck for a little over a month now and it has been great. The element still looks brand new. I've driven in hard rain and snow with it with no problems. I'll be meeting with some gents this weekend that I'm going to let try it out as well. as a matter of fact, if you're in m area and would like to check it out, drop me a line and I'll see what I can do to meet up.

If you would like to view pictures of the preproduction model I have several in My Pics.

It looks real nice.

But wont the metal body heat sink the engine compartment heat? That would warm the air to the engine.

Yes Aluminum conducts heat better than plastic. However it makes no difference. IIRC when the engine is flowing 300cfm the air speed in the intake is around 200mph with a complete air change happening four times a second. There just isn't any time for the air to pic up the heat. If you pop the hood of you truck and look around the only thing the intake air goes through that isn't aluminum is the air-box and intake. I would bet the the only reason the air-box and intake are made of plastic is expense. Also one of the most popular performance air-boxes out there utilizes an aluminum intake tube and I've never heard of any issues with it.

Looks a lot like the setup on my Kobota Tractor. Design is real good at knocking down particle 10 dust. Likely excellent on the road also! Will follow development as I'm looking to change.

BlueOx03,

I really like what I see. It would stand to reason that this unit "should" filter out finer particles than any other aftermarket unit, since it is using a tighter woven filter media. I would also guess that since the filter element has more filter area than a stock one, It would flow better than a stock unit.

However it still uses the stock ducting.
Is that any restriction on the D-Max???
Will UMP make ductwork for the D-Max??

Is there any Data to show airfolow numbers on this unit compared to the AFE, or others???

AFE Level 2 is what I was planning to get. However if the UMP filter is Proven to flow as much or more I will buy it because it "Should" protect better.

lol... looks like a HMMWV air cleaner mod..

That's what I thought. I've got my AT coming up soon. Might have to see if the shop has any extras off wrecked HMMWV's. Maybe a Marine version with snokel.

It's on their web site now.

I sent an E-mail to them asking about the "It does not fit the HD version Diesel trucks."


Also asked about price.


BlueOx03, What would it take to get a group buy going?

Will it work on the LLY also?

HOW MUCH????? That little detail was left out of their info....

I dont understand this....


From UMP website
What does it fit?
This kit fits all 2001 to 2004 Chevrolet and GMC vehicles that are equipped the Duramax Diesel option. It does not fit the HD version Diesel trucks. We are constantly working on kits for other vehicles, if you have a problem vehicle that needs a filter kit, please give us a call. Edited by: tanner

The HD version which is now discountinued (2002?) had the 6.5 TD .... They were only available in the 3500 series .... This is what I believe UMP is mentioning to ....

Ok I follow it now...

I've got a two page sales sheet I picked up at a show I can e-mail. It's too big to post and I'm having problems zipping files.

I would be interested in a group purchase.

Intrest in the GP here as well. With all the problems reported with K&N and UNI I'm thinking this is probably the way to go!

Still there is the lingering musical question, How Much is the Filter in the Window?http://dieselplace.com/forum/smileys/Dead.gif

There is a group buy starting up:

Silveradogs,


IIRC BlueOx03 posted it would be about $379 or so. Not bad considering it's all top quality workmanship and aluminum. Beats the plastic ones, at least for me. It looks like they changed the intake part a bit from BlueOx's pre-production model. There is a group by going on but not sure I can do it right now.


LA DMAX

Before everyone gets too excited about the UMP for the dmax, for what its worth, here is my experience. I have the california emissions truck LB7 '04. I installed the filter and all fit pretty well except for the air intake tube pressing on an egr cooling line more than I like. The intake line that goes to the stock air box is used but with the UMP it sits in a lower position than with the stock air box thus pushing down on the EGR cooling line that that sits next to the alternator. Drove the truck 20 miles and no problem. Truck had more pep and had more response over the UNI filter I had in there. Got to my destination, did my business and started up the truck only to see the check engine light. Codes were:


DTC P0101 Mass Air Flow (MAF) Sensor Performance


DTC P1404 Exhaust Gas Recirculation (EGR) Closed Position Performance


I checked and rechecked my connections before I started up the truck. Apparently my sensors did not like the UMP. I reset the codes and reverted back to stock air box and all is well.


I purchased a 2nd UMP filter for my friend who has an '01 Dmax only to find that the UMP will not connect to the air duct because the air duct sits lower with the UMP than with the stock air box and that the small breather box that equalizes the crankcase pressure with intake???(some sort of breathing apparatus not present on the '03 and '04 to help equalize pressure on crankcase seals or something to that effect. It sits forward of the EDU next to the alternator) sits in the way of the UMP opening and the intake tube cannot physically line up with the UMP filter housing. My friend went to his local dealer to identify the part in the way.


The people at UMP were more than willing to work with me on my issue even to taking it back for return which I did. Since I am a plug and play type I don't have the time for experiments. My friend's issue has not been addressed yet since he has not had the time to call UMP and discuss it. He wants to make it work and will experiement to do so.


Bottom line: One size does not fit all and what works on blueox03's truck did not work on mine nor physically on my friend's '01. UMP will work with you if you have the time but do some research before you buy especially if you have an '01. If I hadn't had the CEL the filter would still be in my truck. I like the added responsivness of the throttle but not to the extend of setting CELs.

Hmmm, looks like it is "not quite ready for prime time." Could some of these issues (lineup) be resolved by spacing the filter mounting up for interference and alignment - or does that create an upper (hood) clearance issue? Interesting product, but I don't think I want to "prototype" on a $300+ purchase.http://www.dieselplace.com/forum/smileys/Confused.gif

Discussed the issues maxinDixon had with UMP today. They have not been able to duplicate the failures he experienced, but are working to duplicate. EGR code may be due to placement of the canister against the EGR line, so they are looking at the mounting bracket. MAF sensor is still being reviewed. They expext to finish the evaluation within 2 to 3 weeks, and then make the filter available to the public.

Could it be another one of those "California smog issues"?


I have a CA. '04 LB7 if they need another test vehicle http://www.dieselplace.com/forum/smileys/Big Smile.gif

blueOx03 has a cali emissions truck too with no problem. Mine might just be finniky.


As far as the placement of the canister for the EGR, the line was not kinked or pinched but just was pushed over to one side so I don't think what was the issue. Could be the placement of the MAF on the canister seeing an air flow pattern foreign to computer parameters that set the codes. Tech at the dealer said that there were 2 failures within 400 cycles whatever that means.





On edit: Mounting the UMP up as it were would indeed create a clearence problem with the hood.Edited by: maxinDixon

My truck, as well as the local test truck have the CA emissions package and have not thrown any codes. There were however some design changes from prototype to production that may have created the problems. I did some testing to try to help figure out the problem with truck. I unplugged the MAF/AT sensor and ran it. I took awhile, but it thew the same MAF code. I worked with a tech at a local dealership to read and clear the code. He said he's seen the same code with the the stock air-box just after service. apparently the contacts inside the plug don't always make good contact. I would guess that the design change and/or the connection to the MAF/AT sensor caused the problem. I figure the lack of AT signal could have caused the EGR to close when it didn't need to.
I talked to Cliff the other day and UMP plans have this all ironed out within a month and they are not selling any Dmax super filters until these issues are resolved. Since I've been running the prototype for over 400 miles now with no problems and laid down 411/797 on the Dyno a while back, I'm sure they're on the right track.
I also asked about the group buy for you guys. He said they could work something out. There is someone else here who has talked to Cliff about this and will be setting up. I also mentioned to him that some vendors here have offered discounts to members here for a limited time. So it may be as easy as giving them a call and telling them your screen name here to get a discount. I'll keep you all posted as I am updated.

Maxindixon, did your friend ever get the filter working on his '01? I looked in my engine compartment and saw the part that blocked the install. I was trying to find a way to move it, but looks limited by hose length and there was some wierd valve that looks like a air valve or something which has to come off to loosten the bolts and I'm worried it might be pressurized?

I don't know and haven't talked to him lately. He is busy planting rice now. I know he was talking to Cliff at UMP on a remedy but I don't know what progress he has made.
