Intercooler
- Thread starter LarryJewell
- Start date
Been wondering this for a while myself, but people are pretty tight lipped about it. From what I've been able to find out Spearco makes the PPE cooler, but the PPE cooler has better specs supposedly.
I've read on TDP of a couple guys having issues with the Banks not being able to handle much boost. I think it was Nasty Girl that said he went through 3 of them, and Banks response was that they were not intended for performance trucks. I've also read about people running 60+psi and been fine with them so who knows.
From an efficiency standpoint it makes a lot of sense to me as an upgrade, but the prices I've seen are pretty high for the modest gains the manufacturers say they will produce. Hopefully we can get a good discussion on here, as the other boards I've been on haven't really been helpful when it comes to this particular discussion.

custom intercoolers...
If you want some help on intercoolers, Bell Intercoolers bent over backwards to help me on a recent project. The font of my buggy is not wide enough for a standard d-max cooler. The engineers at Bell worked with me to design an intercooler that can double the delta-T difference from stock. Colder air is denser and that is why sum will dump an ice chest on it for a quick bump...
Check out their web site... I paid $1200 for an intercooler rated to 900 hp and it fit in my narrow space available...

I've said it before an i'll say it again if it works for Casper it will work for any of us.
After having looked at a stock LLY intercooler and the Banks unit I can't honestly say there is much of a difference. What I do think helps out quite a bit with the Banks is the upgrade to the 3" tubing. With the way our stack is set up its quite hard to fit a larger intercooler into that space but I am sure with proper designing that you could increase the efficiency. I will be getting a PPE intercooler here in a couple of days and am interested to see how much different it is than the stock LB7. Also I will be adding a second map sensor in the tubing and re-wireing the IAT sensor to log before and after temps at the turbo inlet. I will post up when I get it done and let you know what I find.

How are you going to standardize before/after results?
You have to be absolutely sure that ambient air velocity or pressure differential is identical in each case. If you come up with a way to do this, I am really interested in your testing.
I was talkin to a guy at my local speed shop today and he said he put a spearco in his lbz dually and dropped egts 300 degrees, no specifics if this is over all or at cruising or when beating in it. I dont know him to well but I have talked to him a few times and we have swapped information that we have learned and tried. for me, i'd have to see it first hand . and that means to try it myself.
respectfully, this is not remotely possible. Perhaps it was in combination with a number of other mods.
50 degrees is about the most improvement to be had with a CAC swap alone. But there are a number of other areas for egt improvement also.
right. thats exactly what I was thinking 50 to 100 degrees sounds more reasonable. 300 sounded quite extreme for that one mod alone. but I smiled and said " no shit, really? I gotta get me one of those " lol
the Stock outlet on my intercooler and lines are 3"
If you just cut off where it swedges down at the Y pipe and turbo outlet,You will have pretty much a complete 3" system
granted you would need to replace the silicone hoses
As of right now the smallest part of my system is the DS I/C pipe right at the steering shaft
Or did the decrease the I/C ID on the lb7 after the 2001? My 05 I/C lines are smaller

I believe it is just a matter of the end point being lowered by the start point. If entry charge is 50 F lower, then the end product is typically 50 F lower. Nothing burns better or worse.
Just spent a weekend at 7000 ft doing just what you described.
The CAC tubes do make a nice difference, the 2.5" tubes are just too small for the hot side. If anything I recommend to people to change that side at a minimum. The cold side can be left alone, changing it is a smaller improvement.
BTW, with little effort I was able to get the "cold" side to near 300 F. I was verifying that all that mouthpiece theory was correct, and that big time heat is the result of oe intake restriction. I feel very confident now that it is the main culprit in LLY overheat, along with the hot air intake design.
The elevation just exacerbates the condition, with still lower CIP.
Will look forward to your testing. But if using a stock LLY intake, THAT is the best area to improve intercooling. That is prevent the heat from forming in the first place.
Nothing really fast with a turbo or supercharger runs an intercooler.
If you've got the power to push the air in, it's temp is not as important as you would think.
I catch alot of "heat" for this theory, but all my math says that at full tilt, the air is moving too fast for today's crop of intercoolers to be effective.
