birdshill123 Posted May 22, 2022 Share Posted May 22, 2022 According to Pittsburgh Power 5 or 5 years is the average life of an oem cac. But there are aftermarket units that are sandwiched with some sort of rubbery gasket between the layers. Expensive but individual cores can be replaced. Custom made.

timaz996 Posted May 22, 2022 Share Posted May 22, 2022 (edited) When the shop installs the CAC they are going to add rubber in between the mounts to help. This is why I'm having a OTR type core put in. And I plan on turning down my boost 5 psi. So I will see how that goes.

birdshill123 Posted May 22, 2022 Share Posted May 22, 2022 Here is my 2 cents worth: Your unit came with a 350hp isc. You modified it to have 50 % more HP and about 40 % more torque. Supposedly Monaco installed a rad and cache to handle the original specs. Did you change to a larger cac? I have always maintained that a MH is not a hot rod. It is one thing to do impovements to the living quarters or something like battery capacity. Fooling with drive train is tricky. Truckers do this but they can easily change to a bigger rad. The transmissions can handle lots of HP. Sometimes Cummins can improve HP with software but it is a small increase and Torque usually does not change.

timaz996 Posted May 22, 2022 Share Posted May 22, 2022 Hi Bruce, I have had zero problems with temp, either the trans or engine even in hot temps (110F) My problem has been the CAC cracking-leaking. So that's why I'm doing the modes listed above. Tim Link to comment Share on other sites More sharing options...
Paul J A Posted May 22, 2022 Share Posted May 22, 2022 I had a 525 ISX in a 07 Executive i did the following changes to the intake and exhaust components. I replaced the OEM air cleaner with one from AFE, which had a washable filter element and more CFM capacity, same micron spec. Next i replaced ALL the pleated intake hose with rubber fittings and aluminum tubing from intakehoses.com. That's what truckers use. Got rid of all the air friction in the intake. Next was a resonator to replace the muffler from dynaflexproducts.com. Largest MFG. of class 8 truck exhaust components in the U S A. Did not like that so i went straight pipe. . Here is a picture of the results on a screen shot of my Aladdin system. Performance was great and my average CRUISING MPG went up. I cruised at 1350-1400 RPM, 61-62 MPH. THIS trip was turned ON when i got on the Exway entrance ramp, and turned OFF when in exited the Exway. Link to comment Share on other sites More sharing options...

Can do more harm than good. Link to comment Share on other sites More sharing options...

They have the Red boots like mine on there along with others. What model of hose did you use? I'm in the process of having my CAC re-cord and now would be the time to change over to them.

Tim Tim; I Sold the coach in 2014. I do not have any pictures. I simply followed the existing path of the ducting from the Air Cleaner to the inlet on the upper, roadside corner of the engine compartment. https://www.intakehoses.com/ was very helpful on the PHONE. I used a straight rubber fitting at the inlet end of the air cleaner, next a lenght of aluminum tubing, then a 90 degre rubber elbow, then another piece of aluminum tubing up to the coach inlet. Appropriate clamps were also purchased from intake hoses. This was back in 2011, and a few guys used stove pipe fittings and stove pipe to accomplish the same thing. I choose the material i used . Good luck with your project. Edited May 23, 2022 by Paul A. added info Link to comment Share on other sites More sharing options...
J & Di Cooper Posted May 23, 2022 Share Posted May 23, 2022 Hello Tim-AZ, You mention turning your boost down 5 psi. What does your normal boost run at full throttle? I have 2005 400 ISL which will show 30-33 psi at full throttle. I know you have a different engine. Any others with 400 ISL want to share their boost pressures? Might save someone some $$$$ for a CAC replacement. Choose to enjoy this day, you might not get tomorrow. John Link to comment Share on other sites More sharing options...

(stock for my engine is 24 psi) After I verify everything is working as it should I'm going to adjust it down to 30psi. In hopes I won't have anymore CAC problems.

What’s a RAD? Ed ‘05 HR Ambassador Link to comment Share on other sites More sharing options...

It only gets worse in military equipment: the SLAMRAAM mounted on the HMMVWs makes a great SAM but not as good as the IAMD using the NASAMS equipment. It is mystifying.... 27 minutes ago, 6Wheels said: RAD = Rare Antarctic Disease By the way thinking about carrying this around in the back of my RV is hilarious Link to comment Share on other sites More sharing options...
