Quiet Your CTD With ATP!

[JBonpua]

First, I am in no way shape or form associated with ATP or their president Tim Thompson, just a very satisfied customer. I purchased the valve cover and oil pan blankets for my 06 Megacab to make my ride quieter. I visited ATP factory in Irvine CA on my way to May Madness for the install. Two of his technicians did the install. In addition to the valve cover and oil pan blankets, Tim had his technicians install an exhaust manifold, turbo/down pipe heat shield. The heat shield is made out of high tech fiber sandwiched between Inconel alloy skins. Let me tell you this heat shield works! When I arrive at Pahrump Nugget’s parking lot for May Madness from Irvine, while the engine was still running, I popped the hood and touched the top of the manifold heat shield expecting to get my fingers burned. To my surprise, it was not hot. It was no hotter than the ambient air around the engine bay. This tells me that the heat from the engine is kept within the manifold, turbo and out the tailpipe and not heating up my engine bay and the delicate ECM and other electronics and wires.



Wit all these engine sound suppressions it is making a difference. Although you still could hear the Cummins making power, it is now much quieter.



Tim’s operation is top notch. His main business is industrial, marine and military. Since he owns a CTD, he designed a kit for our truck. ATP’s product is not cheap. However, you will get the best there is from a company that’s been doing engine sound suppressions for over 35 years. Give him a call and tell him that a TDR member from Sacramento sent you and he will take care of you. ATP can be reached at (800) 826-8417, Advanced Thermal Products.

Don't worry too much about that ECM - they're pretty tough, as I understand it. All Cummins ECMs are mounted directly to the engine block. They must be tough.



I'm not convinced that insulating the engine is the best thing to do. Sure, it will provide more energy for the turbo, but other than that I think it might be better to let the engine shed heat.



Nevertheless, your under-hood area looks great. You've really done a fine job with it!

surprised you had a problem w/ the noise from the CR



I put sound deadener in my truck, and it's super quiet now

What is sound deadener and where did you put it to quiet your truck??

 

[Forrest Nearing]

I use Raam Audio Raammat whenever it's available



apply it to interior sheetmetal to cut down on interior noise

The 3rd gens are all generally quiet unless you have advanced the timing so much that you get the timing rattle as when I had the Smarty on odd # SW so I now run on even # SW.



I have a 37” Goodyear GSA and they sing over 40 MPH. I just wanted a quiet ride so I did the engine and the cabin.



Ryan, Thanks for the complement on my engine. The valve cover and the oil pan blankets are just for noise suppression purposes and not designed to trap heat although it might trap some heat. The exhaust and the turbo/down pipe however are designed to keep heat in that area and no sound insulating properties.



In addition to the engine sound abatement, I’ve also done the entire cab (doors, back and floors) and hood. I’ve lined the interior and exterior doors with Dynamat Xtreme and Second Skin Luxury Liner Pro (acoustic blocker/filter). If you tap on the doors, they are dead and will not resonate. I’ve just finished lining the hood and will add Second Skin Motor Mat. You can see my doors with just the Dynamat Xtreme and then with Luxury Liner. If you look closely inside the speaker hole, the door skin on the outside of the truck is linned with Dynamat Xtreme and then Over Kill Pro (sound filter). The hood is still not finished. IMO Dynamt Xtreme followed by Second Skin Damplifier Pro and followed by Raammat are the best sound deadner on the market.

ahh, bravo! my biggest complaints are exhaust resonance and tire noise. I've got my entire cab done, just haven't gotten around to the doors... hoping they'll help w/ the road noise.

 

[rbattelle]

Wow, very impressive body of work with all that Dynamat!

Must be whisper-quiet in the cab.

My compliments on a very thorough Dynamat job. Coming out of a '99 though,I haven't found the need for further sound suppression. time will tell though. Thanks for the informative post.

what is that on you bypass filter? little magnets?

 

[JBonpua]

Thanks for all the complement. I few TDR members that saw my truck at May Madness was shocked how solid the doors sounded when you knock on it. You could still feel the vibration of the CTD but not much noise…almost as quiet as a Lexus. It is harder now to figure out when to shift as the engine noise is almost gone.



It will definitely quiet the road noise. I did the doors first as I thought it contributed to more road noise than anything. You must do the inside and outside skins and if you can, put some kind of acoustic foam after the dampning material like Dynamat or Raammat.



Yes they are little rare earth super strong magnets on the bypass filter. if you look closely you could see a Flter Mag in front of the filter. I have many more magnets attached to my full flow filters, oil pan and both diff covers.
