Re. the overheating issue with the GMC LLY engine; My newphew recently installed an aFe Bladrunner Turbo Inlet Manifold on his 2005 diesel. Do any of you have any knowledge and/or experience with this device? It's supposed to increase the air flow thus allowing the engine to run cooler. Thanks.

It may help some.
Seen This Yet
Seen this yet II.
Some of the info is no longer available. But there are several other option to the AFE.
Kodiak Mouthpiece.
LBZ Mouthpiece.
Rick Dance Mouthpiece.
Doing a search on Diesel Place for your engine will get a lot of info do stop LLY overheating.

Thanks ronfisherman. I tried doing some research on thedieselplace but found it to be confusing. There are literally pages and pages of info. on the over heating issue but so much of it seemed to be people arguing over the issue and trying to prove each other wrong instead of giving good factual info. I have found in the past the RVNet people are much more apt to give good solid answers with the ultimate intention of helping each other. Didn't mean to sound offensive as I have read good info. in the past on that forum on other topics.

I really don't think anybody is trying to prove anybody wrong. There are two schools of thought on the subject. Each has their theory on what is a better mod. Kind of like what is a better cam. Or better chassie.
One is the mouthpiece and feedback theory.
The other is the V2 cooling mod.
Both are legit theories.
If it was me; I would do the mouthpiece/intake mod and see how that works. Not enought? Then I would do the V2 mod also.
You really want to talk to a VERY knowledgeable person? Talk to a person by the name of Killerbee on this forum. He is in the mouth mod camp.
Good luck!!!

I'm sure you're right Turtle N Peeps, those guys on that fourm just seem to be awfully short with each other at times. I didn't mean to sound offensive. Also, many of them are so much more knowledgeable than me perhaps I feel a little intimated.

Salem,
I installed the AFE mouthpiece about a month ago and have seen much lower incoming air temps than stock. I have been monitoring all temps very closely using my Banks IQ since all the stock gauges are lying. Now I have to say that I have only worked the engine once on a 103 degree day and had no overheating issues. It's hard for me to test it as hard as you can because we have no mountains or long stretches of heat in Minnesota.
As Turtle stated, slowly make the changes and test. The V2 mod is very expensive and you have to build and install it. No cure in a box going that route. Another item to look into is blocking the EGR but that would have to removed for any emission tested required by your state. PM for temp data if you want.

No worries man. No offence at all. I just want to help you out and I'm sure the others do too.
Like I said, just two camps of thought. Thye just don't want you to make a mistake that's all. IMHO they both have their merits.
Talk to Killerbee. IMHO whether you agree with the mouthpeice or not he is VERY fair and very knowledgeable on the LLY engine.
Like I said, I wish you the best and good luck.

JKrussow: Thanks for the info. Do you mind if I ask just why you installed that device? We're you having an over heating problem? Thanks. Plus, have you noticed any difference in performance, mpg, etc?

Most people install the Kodiak, LBZ, and aFe mouthpieces because the stock LLY mouthpiece has a small inside diameter and an apbrupt 90* turn into the turbo which, many believe, creates additional pressure and turbulence in the air flow. I installed the LBZ mouthpiece because it's a factory piece and half the cost of the aFe piece. I don't know if the aFe piece has a CARB EO number, so it could be an issue come smog time since it's an aftermarket item. Unless the smog tech really knows what to look for, the LBZ piece won't be noticed. I did notice slightly better spool up and smoother acceleration after the mouthpiece install.
As far as the overheating issue is concerned, I followed both camps' schools of thought and finally decided on the V2 option. The V2, which is no longer available, was a complete kit designed and built by a fellow in Texas. The replacement idea (created by engineer837 on the Dieselplace website) for the V2 requires more hands-on from the truck owner, but all the parts, with the exception of the radiator can be purchased at hardware and auto parts stores. Engineer837 has a complete parts list available for anyone wanting to do this. The new radiator is built by a fellow named Ron Davis in AZ, I believe. The replacement is much more serviceable by the owner; I would have opted for this approach had I more time to build it.
I live in the foothills below Kings Canyon NP and tow a 36' Cardinal 5er with a traveling weight of around 13k lbs. Before the V2, I could pull onto the highway on a 90* day and have my ECT at 240*, IAT at 234*, and my trans temp at 225* in about 5-7 minutes. Now, at the same ambient temp and with the V2, my ECT is 217* at the highest, IAT is 150-170*, and trans temp is 200-210*. These temps are according to a Scangage II monitor which I bought due to the lying ECT gauge.
