Does anyone have technical info on aftermarket intercooler?
Egt drop? Intake air temp drop? Pressure drop? Anything to prove an aftermarket intercooler is worth buying. I have seen some results from mishimoto but that was for a 2nd gen. Their intercooler dropped an average IAT by 10*. Wanting to compare Spearco, mishimoto, AFE Bladerunner, On3. All these companies claim egt drop of up to 200* also intake air temp drops. But have not found any proof of what they claim. Thank you
 
Mishimoto has a big write up on the 2nd Gen coolers, but I don't think they have one for 3rd gen. If that helps....
 
Of I could I'd buy one of each. 3 dyno runs with each. And daily driven/towing for a day. Data log everything. Post results.

On a 3rd gen I wouldn't consider replacing the stock metal cooler until you are above 1200hp. I dont know anything about your setup, but most trucks would benefit more from a properly sized turbo setup than an different intercooler.

Airflow improvements should go as follows...

#1 Turbocharger(s)
#2 Aftermarket cam
#3 Head work
#4 Intercooler
#5 Intercooler piping and intake horn IF intake has been milled.

Just my opinion, from some guy on the internet. :bang
 
An intercooler will not be a miracle worker on these trucks. They aren't even needed until higher horsepower numbers as stated above. The intercoolers are quite large in them from the factory.

The stock ones do a pretty good job with cooling, and there's not much of a pressure drop.
I'd upgrade if my stock one ever failed or if I was lucky enough to find the time and money to do a full race truck build.

A cam is going to give you a lot more noticeable difference for a similar price tag.
 
I run a 2nd gen stock replacement mishimoto on my street/race truck. I see 540-575*F pre charge air cooler, and 106-110*F post charge air cooler for peak temps. I was really impressed with how well it works.
 
I blew my stock intercooler. Cast end tanks. Have a 188/220 cam, ported head. Full engine by D&J. I'm mainly just asking for proof of all these companies claims on their products. I dont like spending my money to buy a product that doesn't live up to the claims. I like having real world evidence. The only thing that's left to purchase is a intercooler.
 
Im not sure your air and fuel setup, but when mine pops or i get the extra money im going to go with banks. Ive had good luck with theirs on my duramax dropping egts around 200*++

Thank you for your feedback. I tried filling out my truck specs but nothing was saving. Fuel =250% Air= 66 over 85. Just a grocery getter.
 
Josh, an employee here at the shop just installed an On3 in his 2005 and it was a pretty large and heavy unit, I was impressed with the overall quality considering the price point. We've installed and dyno tested a couple mishimoto 2nd gen CAC and they are much heavier than stock (much larger aluminum heat sink so to speak) but sadly, on the test mule Oscar it didn't pickup a measurable power gain on the chassis dyno.
