2nd Gen Non-Engine/Transmission Quiet truck?

[Tiger Rag]

Quiet truck? Advanced Thermal Products?

Anybody try this stuff before? I saw it on the banner ad and thought I'd check their site out. If it works well, it might be worth it, but man it is high $.

I've read about at least 4-5 products that were sold just for that use - big bucks , then others going to home depot and buying simalr products for reasonable prices.

Yep, I talked to a guy that said TDR did a test a while back and tried several of the higher end products and only had a . 5 - 1 decibel loss in the cab. They used some rubber matting of some sort from Lowe's or Home Depot under the carpet and had similar results for less $.



I decided to go ahead and try some Fatmat, Rattletrap at www.fatmat.com and see what my results would be. They claim 6-8 decibel drop on the cab with their product. We shall see, but my buddy that used dynamat had nice results with his truck. It is much quieter than mine. My fatmat should arrive tomorrow for install this weekend. I'll notify of results.



The other head and oil pan blankets do look interesting though. Anyone that has tried them, please let us know your experience.



Thanks, Matt

Advanced Thermal Products

Tried to call ATP yesterday but got a busy signal. Will check in with them to see if they claim an in cab decibel loss, I didn't see it on their website. I'm just curious to see if anyone has actually used this product and has real world experience. Any feedback is appreciated.



Thanks, Matt

When I first got my truck and realized how loud it was (I live in a dense neighborhood and **** a lot of people off if I arrive/leave late/early) I researched this option quite a bit. I think I talked to 2 or 3 people who had the whole ATP package installed and they all said it made a noticable difference, but no one convinced me with was worth the $$.



If you are looking to reduce in-the-cab noise you are much better off insulating the cab. If you are looking for outside noise reduction, I'm told the ATP oilpan cover is the most effective piece.

 

[Beast2B]

Worth the money is a big maybe, but the turbo and exhaust products work great. SOME noise reduction, but the best part is the heat retention in the exhaust. We run this on many Cummins generators and you can hold the exhaust housing of the turbo after running for hours.

I have the ATP Wrap in my '02 Ram. I don't have a decibel meter so I can't say how much the noise reduction actually is, but I do remember that when I installed the kit last year, my first impression was disappointment. At first it didn't seem like it made much of a difference. For prolonged use however it is a different story, the kit made long drives bearable for me compared to the original setup. I went with the ATP kit because I needed something in a hurry and didn't have time to mess with tearing apart the cab to insulate it. The kit was worth it to me for what it did, but I'm not sure I would highly recommend it to anyone as I believe that you can achieve the same or better results by insulating the cab, which I still intend to do next year.

The two most effective pieces of the kit are the oil pan cover and the valve cover.

I talked to Tim Thompson at ATP this morning... ... well right before lunch for me, but the morning for them in CA... ... but anyway, he was a great guy, especially the fact that the president took my call..... first class guy. He gave me several minutes of his time which I appreciated and bottome line here is what I can decipher of his product line. He does these type products more for commercial generators, boats, race cars, etc. , but owns Dodge Cummins trucks himself and wants to offer the products to those of us who also enthusiast. He claims not to have a large volume of business in these products and it is not his plan to get rich off these, he is offering them as a service to us Cummins guys and the process is labor intensive to manufacture these.



Anyway, his 99 dually CTD had a decibel reading of 90 db's or more and after using the basic kit, it reduced the in cab readings to 70. After coming up with the oil pan kit it lowered the db's to 60... ... . Wow! If this is true, that is unbelievable. Now he did have the 3. 55 gearing which his truck works much less hard than mine with the 4. 10, but still, that is a significant loss in noise. Going from memory the basic kit which is valve cover, exh manifold, turbo, elbow is somewhere in the $750 give or take and the oilpan/valve cover combo is $500. That is definitely pricey, but if it provides the claimed noise reduction it would be worth it.



Anyway, thinking about it, studying on options, and saving money in the time being.

Cab Insulation

I pulled everything out of my truck last winter and laid down the single side sheet insulator from Geno's. Went as high under the dash as I could. Included the side kick panels and doors. Did not need to use tape but did buy a can of spray contact cement from Home Depot for doors and back cab walls. Used 3 rolls. My wife & I think it made a big difference but have no measurements to give you. It is still not a quiet truck, just quieter than it was and not too expensive. Good luck.

 

[Tiger Rag]

Thanks KTimmer! I actually pulled the interior out last weekend and put a dynamat extreme alternative down: Fatmat Rattletrap (much less expensive). I ordered a bulk pack with 70 sq ft. It did pretty much the entire cab, including all 4 doors with only a few openings here and there. From what I understand about sound deadening, you only need to put a piece here and there to absorb the vibration of the steel anyway. Well, bottom line, it worked very well. The stereo is much more audible now and has much more bass now. It seems to me to do as well as my buddies truck that used dynamat extreme and their floorliners. It did not take all of the clatter out, but I enjoy the sound of the engine for the most part..... just not while on the cell phone at highway speeds. I did go ahead and order a couple of the pieces of the ATP wrap; the oil pan cover and the valve cover blankets. I'll keep you posted if they make a difference..... I certainly hope so given the cost. I hope they do what Tim Thompson claims they will do. He was a real gentleman to work with and an all around fine human being from our conversations.



By the way, here is a great, however lengthy, thread on sound deadending. I read it all to absorb all ideas I could. Anyway, here is a link for anyone else that is curious: https://www.turbodieselregister.com/forums/showthread.php?t=63647&page=1&pp=15



Good luck to anyone else doing this, there are many good options in the sound deadening department. As I said before, I'll update on the ATP blankets after I get them and install them.



Regards, Matt

Ok, update: I got both the valve cover and oil pan covers on. I did valve cover first and I noticed a difference. Then the oil pan, and another big difference. The biggest volume of noise I was hearing after that was coming from the manual trans shifer, so I pulled the cover off and put a couple layers of carpet padding I had left over from the house and Man, what a difference! The sum of all the parts, atp blankets, fatmat, and carpet padding made a huge difference! I'm happy now and am not planning on changing my 410 gears out anymore. I'm very happy with the results. Good luck to any that decide to try this, Matt

 

[CLamb]

I don't have any of the products above. I think the oil pan deal would be the best bet. To get a little bit of an idea about how much noise comes out the bottom go and try this. Park your truck in the grass, much quiter as the noise from the oil pan can't echo off the concrete. I also have noticed how much quiter mine is when there is lots of snow on the ground. Just my . 02



Who has insulated just the back of the cab? I think I read somewhere on here that it makes a big difference.

 

[Harley152]

I removed the rear seat and did just the back of the cab with lead sheet (roofer's left-overs) I brought home from a job---put the rear seat back in---and now I can hear the fan kicking on and off for the first time!!! It made quite a difference.

Anyway, his 99 dually CTD had a decibel reading of 90 db's or more and after using the basic kit, it reduced the in cab readings to 70. After coming up with the oil pan kit it lowered the db's to 60. .

I have to say, a 30 db drop just in the cab is an incredible noise reduction. I was told an increase of 5 db is doubling the sound, which would mean 30 db reduction would mean how much?... ... ... ..... I am sure someone knows more about this.



If my 98 is that noisy, maybe my kids ARE right, I am deaf.

How do the ATP products affect the engine temp?? Mainly the oil.

I haven't seen anything that caused any worry. They fabricate these for race cars and are supposed to help with extreme heat. That may be mainly egt's and the exhaust manifold covers from ATP are supposed to not allow the heat to escape until it gets further down the exhaust and away from engine components. I'll pay more attention to the oil temp, but like I said I haven't seen any concerns yet. I guess mid-summer on a hot day may be a better test. If I see anything though good or bad, I'll update.

 

[Rman]

One of the advantages of thermal wrap is noise reduction, however, the heat retention is the selling point. Engines are EXTREMELY unefficient, basically all the energy is lost in heat transfer to the block and associated metals, this heat transfer is wasted energy, keeping this heat inside the engine and in the exhaust stream is beneficial.



I'm sure egt's will be a little higher (probably no more than 50 I'm guessing), and temp's inside the engine will probably reflect slight increases, but insignificant. The thermostat may stay open longer is all. This energy retention, should, in the long run, net increased power and mileage. Nothing markedly worth advertising a net horsepower increase.



I remember from my studies most gas engines are around 15-17% efficient, diesels are normally slightly higher. A % here and there will make a difference overall.



I want to buy this ATP wrap, but man it's $$$. I think Y-knot did a budget exhaust wrap, don't know if he ever tackled the valve cover.

 

[Cummins Thunder]

I have wanted to put the whole ATP system on mine but price holds me back.



Their hood cover is a must for us 02-04 guys But then comes that price

[Demons_Ram]

I was thinking of having my new ram Ziebart rust proofed, not so much for its ability so stop rust but to make it quieter. Has anyone tried this???

Coop, you captured my thought as well. Why wouldn't some sort of undercoating on the valve cover and oil pan kill the noise?

 

[MAleksandrowicz]

buy a gasser if you dont like noise. easy fix.
