I'm sure everyone here knows what a CAI (Cold Air Intake) is... designed to draw cooler outside air into the engine instead of warm / hot underhood air. This is argueably desireable in summer when the under hood temp climbs outta sight. These thoughts carry over from our experience with gassers and I'm not at all sure they directly apply to a compression fired engine (diesel)... especially a turbo-charged intercooled diesel. Any rate the OEM air box is plumbed into the fender which draws cold air from behind the headlight... Atmittedly not a huge passageway but a CAI. Just a general reminder, that diesels "fire" from the heat of compression. A turbo adds temperature when it boosts the charge pressure but then in goes through the intercooler... before reaching the intake manifold. NOW I want to flip flop the scenerio... in winter the ouside air will be well below the most economical point. The IAT sensor will adjust the fuel to run righer in order to make it run. The cold fronts so many of us use block some or all of the grill raising the under hood temps above ambient. Those who are running BHAFs are already drawing engine room air... despite any heat shielding panels that may be in place. So this may be benificial in drawing the warmest winter air available. I'm still running the stock air box plumbed into the fender. Even with the cold front in place I suspect the air drawn in behind the headlight is still colder than underhood air. So my theory is that it would be better to disconnect the snorkle into the fender & block that opening in winter. Maybe even do the swiss cheese mod to the airbox. Your thoughts?

OK, I'm finally gonna spend some $$$ and get a cold air intake, high rise intake manifold, and injectors. What I'm wondering is which is best for each. Here is what I was going to buy before asking for suggestions, let me know how good or bad this combination will be. 1. Injectors: DDP 100hp 2. Intake Manifold: CFM 3. Cold Air Intake: S & B The only othe upgrades I currently have is a Edge Juice Box, Air Dog 150, Upgraded Turbo, and 4 inch exhaust. Let me know what you guys think.

I am wanting to know what upgrades I need to do to lower my egt's. Right now I run a tst powermax3. On level 2 runnin down the interstate truck runs 800 degrees.. On power level 6 pulling 10k pretty slow under 40 i ran well over 1200 pullin a small hill.. So I need to make some changes to keep it down.. On level 8 goin 60 I hit over 1200 also.. So if i decide to pull a load down the hyway at 60 egt's are gonna be crazy high.. so lets here your ideas..

What I have done: 1. #6 Fuel Plate - Full Forward 2. Boost Elbow 3. 4" Full Exhaust 4. TC Lockup Switch 5. BHAF http://www.dieselpowermag.com/tech/dodge/1002dp_1994_to_1998_dodge_ram_power_recipes/1500_budget.html What I'm thinking of doing (in order): 1. Timing 2. 3K RPM Springs 3. Injectors I'm expecting my trans to blow up, so that will give me an excuse to go to a manual or build the 47rh. What I don't want to do is blow the head gasket, so I don't want so much power that requires me mod the head or valve springs.
