What's the best 2nd gen CAC for the buck

Keep saving your cash for twin turbos. That's the only real way to tow and keep things cool with a decent amount of fuel. An aftermarket intercooler is just a bandaid.

My truck smokes a hell of a lot more than it used to all of a sudden to. I just cleaned my air filter and changed oil so I'm lost as to why. Tyler, didn't your truck do this a while back?

not sure how your weather is but my truck smokes alot when its above 75* out. I was used to driving it in winter when I could drive somewhat aggressive and not roll coal...now in hot temps i have to drive very carefully to keep smoke down.

if you just recently had your first hot spell, then you might be seeing more smoke and it will just take you a few days to get used to driving without smoke again.
 
Give Joe Hellman a holler Jory, methinks he might be able to help you out for a few $$ cheaper than the Spearco.
 
The common rail CAC is a better piece than the 24V version, and it actually does an excellent job of removing heat from the intake charge.

A popular aftermarket CAC manufacturer claims a 50% reduction in pressure drop, from 2psi down to 1psi over the stock unit. It is a more efficient design, and looks awfully cool - but of course isn't a cheap BOMB. There are many other places I would look to spend performance $$$ before a new CAC, however installing one won't hurt anything except your wallet.

I've documented (with multiple electronic pyrometers) 3rd Gen OEM CAC thermal performance to give part-throttle (driving around town) differentials of 5-10*F on hot summer days (90-105*F)... 500HP of fueling with the skinny pedal jammed into the firewall creates a max differential of 25*F.
Probably would go a little further, if there was more road or more gear (even though the 37" Toyos make +120mph doable).

More specifically, max fueling on the '05 produces 355*F at the CAC's inlet with a delta temp of ~230*F at the outlet (while the poor 'ole HE351 is churning up almost 50psi boost under the punishment of 75psi turbine inlet pressure)... pretty good for OEM hardware.

I'd expect other common rails to be similiar, although likely producing slightly lower absolute numbers, since I tweaked the '05 with a few tricks to improve both airflow and thermal efficiency in regards to the CAC's heat exchanging performance.
 
p.s. Joe does great work on aluminum heat exchangers - can't beat Made in Texas, by Texicans!

Honestly, I'd keep the stocker. It does an excellent job at keeping temps cool.

I remember reading in diesel power or diesel world that the stockers on, I think 99 to 02s is a really good design and works well. So it should be one of those later on down the road mods... how later, I don't really know.



You should see some of the massive CAC my work makes. Takes two guys to move the biggest of them, at 6'x9'. I've often thought about tying out some of the various coolers that we make, would just have to make sure they were scrapped for visual reasons.
 
Has anyone put a 3rd gen in a 2nd gen? How difficult and how much mod is required? Just curious.

An it is getting to 95F during the day now so maybe that is why mine hazes a lot more now. O well. :D
 
a 3rd gen will not work on a 2nd gen unless you have a gutted engine bay and custom smaller radiator for a racing only application.

the 3rd gens are about twice as tall as the 2nd gen with the outlets in the center, and the second gen is wider with the outlets at the very bottom of the end tanks.
 
$.02you can call Chuck at New Era Diesel (www.neweradiesel.com)his prices beat most, HTT will send u the same direction. I would think for the money water inj would be cheaper& is great for towing. it would be alot cheaper than twins.
