LLY Over Heating While Towing

I have read of that mod on forums before. Several people who have tried that have not seen any difference and still overheat. I think the core problem with that design is that it completely ignores the cooling system. It focuses on air intake which might help a bit, but really isn't going to cool the cooling system one bit. That guy used to be on some other diesel forums I was on. This is not his first attempt at fixing the overheating issue. One problem he always has is that he fails to address the cooling system which would be the obvious place to start. Many of his other "solutions" were scrapped because they didn't work. This is just his latest attempt to prove you can solve overheating while ignoring the cooling system. It may help some people, but I would personally run from anything he is supporting given his track record.

The "Fix" in Maxxtorque is NOT a fix and has been proven to do absolutely nothing. That is the Killerbee theory that was proven not to work. He wont even sell the system to anyone on the West coast. BTW- All the mods done by GM starting with the LBZ where implemented by TXChristopher.
Let me reiterate: ALL LLY's WILL overheat. This has been proven more times than we care to keep discussing. You would think that after over 3 years of threads on this at DP everyone would get the picture.

Go ahead and do KB's fix, be sure to get all of his fixes while your there. How many does he have now??
Let's see, it started with a different air box, then it was a radiator cap, stack seal, oil cooler, programming, boost tubes, now a new mouth piece.....Why has he hit every system on the truck except the one system that truely cools the engine?? Oh, that's right, a 4 page writeup tells me these engines are oil cooled not water cooled. How silly of me. Coolant will only bring the oil temps down a few degrees, hhmmmm, well that's wierd, because I've seen some tests that show that with a V2 installed (the only real fix to date), the engine oil temps are only 15-20* higher than engine coolant temps. So, since I installed my V2, my highest ECTs have been 217* (via data buss) once, but normally, no higher than 207-210* ect. So, that means my EOTs should be around 220-240* max??? Doesn't sound all that hot to me. I have yet to see a true overheating test done on his mouthpiece/intake all by itself, no other mods at all. Let's change the driving conditions too, from cold, moderate hill towing a short, light 5th wheel, to a 90* day and a high wind drag, high weight 5th wheel and send it up an 8% grade for 5 miles. Nothing out of GMs specs, just a normal day in the family truck-ster on vacation. I know the V2 can do it, stand alone. Don't know of anything else.
Now the 'new fix' mouthpiece has merrit, but more on a performance level. Getting air in the engine, faster and cooler will boost all numbers. It should lower IATs, IC has to do less work, less heat all around, so yes the ECT will go down too. Is it enough to cure the LLY overheat?? I doubt it, but it will help.

I cant remember the guys name, hell it may be TxChristopher for all I know, BUT it's basically replacing the stock LLY intake with a LBZ intake, buying a LBZ turbo mouthpiece and some other mods. There is a huge article about it. I will read it again when I get home. The author is a GM Tech and claims it fixes the overheating problem and dynos more power. He's not selling anything, just gives you the GM part #'s and instructions for doing the mod. I dont think Maxxtorque is on newsstands. I have a subscription. I'll read it again tonight and post what I can.
EDIT: I just flipped over to Dieselplace and read TxChristopher's RAD MOD. The fix in Maxxtorque is totally different and doesnt really mention the radiator at all.

nice video... I had my d-max for 2 months and pulled a cummins over the rockies
, and was cussing it like you wouldn't believe sitting along side the road
..... Got rid of an old p-choke that would have pulled it 80 mph over vail with no issue but egt
Ill be investing in a v2 when i get the cash. My truck was stock then.... 65 degrees outside...
I did say pulled a cummins, sorry i had to bring that up lostnwalmart... haha

We live in the west and have the TD-EOC. The v-2 guys have said they only hear their fans once in awhile so that isn't a NO fan story. We had a little fan action towing East on I-90 in May but not full fan and I was happy. I couldn't make the fan come on towing from Az in April to Wash st and I tried but no fan.

#1 what do you pull and where do you pull it?? There is a big difference between 13000# lowboy trailer and a 13000# 14' tall travel trailer/5th wheel acting as a big wind sail. There is also a difference between the hills of Texas and the 8% grade mountains of the west coast. I run a combined weight of 21,500# with my travel trailer reaching a height of 12'9" on a pull behind that has a lot of 'dirty air' past the cab. I could easily hit the 235* range in our moderate 'hills' of Texas. I would hate to see what it could of done in some serious mountain ranges.

The guy who writes the articles for Maxxtorque is Killerbee, not TxChristopher and KB is NOT a GM Tech, he's a keyboard jocky that knows how to write. If I didn't know better, I'd believe him too.
