Any suggestion on a cold air intake box for the LLY. I would like to get air from outside the motor compartment and everything I see still pulls from the motor area.
Dan

Have you considered an 06 CAI?

Dan,

I think most of us are buying the 5.3 airboxes and modifying them for cold air intake. IIRC carhauler has done this and posted pictures on one of the overheating threads. JJ

Just a side note as I don't want to hijack this thread... you may want to consider making your cold air kit removable. I say this because all of the power generation equipment I used to work on was diesel powered, and all of them had two paths for air to follow one for warm weather operation and one for cold weather operation. If you look at the specs for the 06 Dmax it has a grid air heater, my bet is that is due to the cold air induction and the need for warmer air in the colder months to get the engine working properly.

My .03 (I've had to raise my rates to cover the high cost of fuel)Censored

Interesting? I was under the impression cold air was always the best medicine for engines. Can air be too cold? Does the 06 CAI have the ability to draw both cold and warmer air depending upon OAT's? I almost always learn something through these posts. JJ :)

"grid air heater"

will have to find out more, but, my first thought is for starting purposes. But I am really clueless.

Carhauler does not have a CAI to my knowledge, just stack sealing.

and the "gasser" airbox has been pictorialized by oilbrnr. It is as cheap ($37), oem friendly, and almost as effective as you will get. It does need to be modified for more flow.

KB, that's right it was oilburnr. Rick has a modified airbox compliments of Mama Rick as well. Ordered mine on Tuesday, should be here shortly. JJ

Hmm... I doubt the 06 box has the ability to draw both I'm pretty sure that's why they installed the grid air heater. I know on the equipment I worked on we'd start them in the cold weather position (allow the air box to draw engine pre-heated air) then after then engine reached operating temps we'd flip the baffle back to warm weather operation (allowing the air box to draw only cooler outside air), but they'd run fine in cold weather pulling nothing but hot engine air.

Can air be too cold, well I'd have to say yes! -60 in Korea we couldn't get anything to fire up! As far as too cold for combustion I dunno, I'm bettin no combustion would happen in a Diesel at absolute 0 (hehe ok I'll quit being a smartass now)):h

damn that killerbee is quick... hey lookout, no don't sting me... keep away... swat, swing and a miss... maybe next time :D

Engine warm-up time, EPA driven. Engine doen't care. IMO.

My father-in-law was in Korea in the 50's. He told me that the F-86's on Ready were lined tail to nose ( EGR ? ) on the tarmac in the winter. FWIW.

Line up the DMax's, :lol:

LB7's have air intake heaters BTW

LB7's have air intake heaters BTW
Well now that's interesting! I wonder if that could be retro-fitted to the LLY for users with a cold air intake?


While I'll agree the Dmax will run with cold air in the winter, if it's like any other Diesel I've played with it's apt to be quite cranky till it gets up to operating temps. But then again with computer driven firing events it may purr like a kitten, time will tell...


Just throwin my observations out from other Diesels I've used, abused, operated, worked on, etc...

I don't know what a grid heater is, or...but I am sure that the resistive load to substantially heat up 800-900 cfm (our wot consumption) is way beyound the alternator limits. I would find it hard to believe that it is used for anything more than startup glow plug assist, and poosibly warmup,

Pretty sure dwrat doesn't have to worry in Phoenix.


but like I said, I am clueless.

All versions of the LLY have intake air heaters as well... The new version for 06 has just been revised and increased in size for cold start performance and emmissions regs coming in 07.

As for the 06 box, there is no alternate air path. it connects direct to the inner fender, but it does twist the air so the water does not come in and soak the filter. This would be a direct drop in to an earlier LLY withe the box and intake tube.

HTH.

I am having this set-up done currently and is proven to be part of the overheating problem along with programming.

please elaborate. What settup?

already aware of the role hi IAT plays in OH. Is this a dealer mod?

It is through a performance shop. Nothing has been fitted yet, but hopefully soon while their is still some warmer weather to test.

It seems the turbo programming has shown improvements and can vary from truck to truck in oem state. Obviously the intake is a no brainer for gains, and their are other hardparts that involve swapping as well, both from a LB7 and 06' LLY. They are members here, and I will leave it up to them to discuss the details if they choose. Enough guys looking at these combinations and I'm hoping a cure is found. Their really is not another truck I would rather own.

JC Whittney has an air box that I'm thinking of trading my K&N for.It looks to be a lot more effeciant.It has a scoope that comes out under the front fender that takes in air and directs it to the filter directly to the intake.Everything is enclosed so it should be effeciant.

Ohhhh.... Linky please
Yeah I'll admit it I'm too lazy to look for it ):h

From the description, I think this is it...

BodySurfer is runing the Volant, see it installed. (http://dieselplace.com/forum/showpost.php?p=169119&postcount=23)

Looks good, little pricey.

Idahofox

I would be careful of anything that picks up air under the bumper or in the wheel well. My son put a cold air intake on his ricer and got into some heavy rain and hydrolocked the engine. I hope the Volant has some kind of water separation.

Thats the one I'm talking about.It just makes sence to me that it would provide better and colder air.I wouldn't worry about the water,it will drain right out!

For $37 I'll take the warranty friendly route, with superior filtration BTW to anything aftermarket.

I went to Volant's site and can not find it for the DMax.

Same here.

Not sure there is a d-max specific one, especially if side vents are the source

isnt the Grid heater an alternative to glow plugs? And dosent an engine run better with cold gas/fuel and cold air...I thought colder was always better. It seems like my D-max runs better during cold mornings (30 degrees)
And volant makes the cold air intake for Dmax, mine is in the mail as we speak and I think DieselDemon has one...I think.

....isnt the Grid heater an alternative to glow plugs?....

In addition to. Watch your volt meter after you start up, Two steps as the voltage increases; glow plugs OFF, heater OFF. They are Both power hungry.

I second the bad idea of pulling air from that far down on the bumper. Back in 1992 Ford did a set up like this on the Police Interceptor Crown Vics and had NUMEROUS cars come back with locked up motors.....one was from our fleet with less than 100 miles! Eventually they dropped the idea and started pulling air from the fender well which was less likely to have a large amount of water in it....better than the hot air from the engine compartment. I know this might sound like a load of crap, but I own/run a turbo charged & intercooled NHRA drag car and have experimented with all kinds of cold air induction on it. What I've found is that at high boost (25-30 psi) the air would become SO turbulant sucking through a long length of tubing or whatever, it actully hurt performance. The gains of getting colder air over that of engine compartment air was so negligable it wasn't worth it. If you have an efficient IC, which we do, IMO it's not really necessary. I measured air intake temps and found that with a front mount IC I was only looking at maybe 30-50* drops in intake temp...not that much fellas! When the outside temps are cool, the IC is working so efficiently the extra drop didn't make hardly any differnece because the turbo eventually heated the air right back up. Take it for what it's worth, I think $$$ could be spent elsewhere if your looking for HP. Cheers!

Cool, maybe. Who is watching?

Hot..., you'd be wrong. Try 130 over ambient (IAT) and 180 over ambient (Post CAC, charge air temp) for the towing vehicle in the summer, trying not to overheat.

Measured!

The cold air solution is particularly essential to the extreme conditions tow d-max.

All versions of the LLY have intake air heaters as well... The new version for 06 has just been revised and increased in size for cold start performance and emmissions regs coming in 07.

HTH.



Is this the 06' D-max airbox? Anybody have a part number? Thanks!!

Rob

If you find more information on it, we need someone to test if it can be swapped out, maf sensor, etc. It looks like a good idea

KB,

Is this the dual-snorkel box you got from Darrin? Have you put it in yet, and have you seen any changes in performance or temps (I haven't seen any mention on the boxes in the OH threads, so apologies if I missed any)? Got pics?

Joseph

Yes, no I haven't installed. Still testing other mods. But others have, find oilbrnrs pics

But i am wanting to get someone to do an 06 swap project. That may be a better more practical idea

BTW JJ is doing the gas box now. May want to talk to him

Yes, no I haven't installed. Still testing other mods. But others have, find oilbrnrs pics

I thought oilbrnr took an '05 box and put a single snorkel on it, that went to the front of the stack. I guess I'll have to look at the pictures again; maybe I didn't understand it the first hundred times I looked. 'Course, it would probably help things if I took a better look at MY air box! :p:

Thanks,

Joseph

he is using the gas box, 2 snorkel, modified on the bottom for extra flow.

I think I understand now, after comparing oilbrnr's pictures with Kennedy's pictures. It looks like oilbrnr cut out the area for the snorkels, then blocked this single big cut-out, and finally added a 4" intake to the bottom of the box (which then went out to the stack area).

Thanks, KB.

Joseph

can you link the pics here?

Rob

I called my Chevy dealer, he faxed me a pic of the 06' 8.1 and 6.0 airbox. He said he could not find the box for the 06' d-max. Can I fax these pics to someone who can scan and post them? KB, I will test it as soon as I get the correct parts from GM.

colnago

very complete, nice summary

Been working with my GM parts guy to figure out what GM did to the 2006 D-Max airbox. Heres the skinny. For 2005-2006, all gassers use the same airbox, # 25355074. The 2006 D-Max airbox is a new number, 89060671. No picture is available yet. In fact, the part is not available yet. He said it may be available when they get their next parts update. More to come soon...I hope.

Thanks for the update. The air tube is also different, correct? PN? element PN?

Thanks for the update. The air tube is also different, correct? PN? Filter PN?


KB, the tube from the airbox to the throttle?

Airbox to Turbo, tube

Yes, the 2006 intake tube from airbox to turbo is a different number.

The 2006 filter is different as well.

2006 D-Max air tube... 15117966

2006 D-Max air filter.... 15282462

Now the 64K question. Is the MAF sensor different?

He also said both these numbers are not yet available.

Also, there is a intake tube from the airbox to the fender, I ordered it and will see what can be done with it to bring cooler air in. It is a 14 dollar part. Number is 15197202, and it fits all gassers 2005-2006. He doesn't show this part for the 06' D-Max. Maybe when he gets a picture it will show it.

OK, finally got prices for 2006 D-Max airbox.

Complete airbox 2006 D-Max....89060671 list price 228.00

Air tube from box to turbo.....15837090 list price 69.91

Filter element...15282462 list price 52.35

There is a chance the airbox will come with the filter, the gasser box does, but he could not tell me for sure.

Other things to consider are if the maf wires are long enough to reach the new location.

Possible different clamps, etc.

:eek: Man, they sure are proud of that damn thing!

That does make it a tough pill. Would still love to see what it draws for IAT, I can't really see it being lower than the earlier model cold air.

Thanks for your effort Rob.

But this new design may allow cold air without water intrusion.

Actually that's not as bad as I thought it would be. $350 or less for OEM cold air intake. That is list, and most people can and do get a discount from there.

We also need to inspect an 06 truck to make sure there are no changes to fender, headlight, or core support area that would be needed to make this work properly on the older trucks.

Correct, that is list. He quoted me 171 my cost for the box. Most anybody should be able to get 20-25% off that.

At those prices what advantage would this have over after market CAIs?

LTChip
OEM, better moisture control, filter availability, and possibly no warranty issues.

Gotcha. Thnx. Will watch this for the first LB7 install of these parts.

I Think One Thing You Are Over Looking With Air Box Temp Is The Road Bed Temp. On A Hot Summer Day The Pavement Can Be 140 Plus. Black Asphalt Can Be Even Higher. Concret Starts Buckling At 140 And Up.. So Inputting Hot Air From Under The Bumper May Not Solve Anything. It Still May Be Cooler Then What Under The Hood, But Not By Much.

Arm

Anyone had a chance to look any more at using the 2006 air box on older LLY's? Kinda like what I have seen of the new filter set up. Probably asking a lot for it to work no problem on a 2005. Sensors almost have to be different.

Hey DWRAT is that one of the Allred girls from the west side ,in your avatar,and did you put that smile on her face ?

I installed a 06 air box on my 05 last week and the intake tube from the filter ass. is 4 1/2in. ID verses the 05 that is 4in. This seems to slow the air flow down in the tube and causes some weird driveability concerns. The readings on the scanner indicate the larger tube is probably effecting the MAF sensor signal. I used the 06 tube from the filter to the stock 05 turbo elbow and adapted it there. The 06 turbow elbow hits the EGR water manifold at the hose nipple. This causes the elbow to exit the turbo to high. The 06 has a tab bolted to the turbo that the elbow rests on. The hose nipple on the EGR manifold prevents this from happening and cocks the whole intake duct at a upward angle. I'm still working on speeding the air flow up past the MAF sensor, maybe a sleeve? IAT seems to run within 7deg of ambient city or highway unloaded. DTC p0101 sets almost instantly when cleared with engine running. Not enough testing to draw a conclusion at this point. I should mention that my truck OVERHEATS also.

p.s. Dont tell but the stock unit is waiting for a trim part, hope the backorder doesnt fill very fast.

Thanks to all the members, this board is great.
