    Default 4BT Engine Quiet Kit

    I just wanted to start a thread on sound deadening blankets Iíll be getting for my truck in the next few months. I just arrived to RC South, Afghanistan so Unorthodox Customs in Puyallup Washington will be doing the work.

    A few weeks ago I was searching for something I can mount underneath my hood to help quiet my engine a little. I came across Advanced Thermal Products http://www.atpwrap.com/ APT currently has a quiet kit for the Cummins 6.7 http://www.atpwrap.com/html/dodge67cummins2009.html as well as the ISB 5.9 the kits consist of blankets that attach under the hood, valve cover, oil pan, exhaust manifold and turbo. I donít know the dB reduction.

    Anyways they currently donít have anything for the 4BT so in Dec, unorthodox customs will remove my oil pan, valve cover, turbo, down pipe, and center dump exhaust manifold and ship them to APT to build a custom setup for my Tacoma.

    I know a lot of people will like there 4BTs a little quieter and hopefully this kit will dramatically reduce engine noise, my Tacoma is very poorly insulated. Because of this my Tacoma should demonstrate how well this kit works.

    The kit is pricy but hopefully if the dB is reduced enough in my Tacoma, that it might build enough interest for 4BTSwaps to have a group buy for other members of the site. Just FYI I am not affiliated with this company, nor will I receive any kick backs from them. I just wanted to pass this information along and once the kit gets put on my Tacoma Iíll update this thread with pictures and if I can find them a dB meter ill get before and after dB rating.

    I'm interested in hearing how much of a difference this kit makes. Any chance we could get videos before and after from inside + outside the truck?

    Hopefully it works out well. I'd be in for a group buy if it does.

    If you can actually get a meter and measure the dB difference from the driver seat that would tell a lot.

    1998 Ford F150 SCSB, 4x2, M5R2 - ex-4.2L, 4BD1T swap in progress



    The difference between 65 and 75 MPH is 7 seconds per mile. Slow down and save fuel.

    Would you need a pretty big radiator with that? I'd imagine a blanket like you described would trap heat. What about weight?

    Here is the price list the companyís president Tim Thompson sent me

    4BT Quiet Kit:
    1 Center mount low mount turbo $325.00
    1 Valve Cover $150.00
    1 Oil Pan Cover $300.00

    1 Down Pipe Cover $100
    Total: $775.00

    like I said before its expensive, but right now the inside of my truck is so loud I have to blast my stereo to here and talking is pretty much out of the question unless you yell. Thatís mainly because I have very little insulation in my truck right now.

    I donít know if heíll lower the price for a group buy, but most places would if you can get a nice hand full of people to get a big order.

    After they get my parts theyíll be able to make a blanket for a HE351VE, center dump manifold, valve cover and the oil pan. My pan has been modified to clear my axle and a turbo drain was added, so if anyone has a modded pan like me youíll have to send them yours.

    I wouldn't think heat would be an issue. 4bt's generally run on the cold side. Most guys complain about them not heating up.

    Ive heard that manifold, turbo, and downpipe blankets will noticeably lower egt's... Looks as if the heat normally put off by the exhaust side is routed away from the engine bay and might balance out the gained heat from the other engine covers. No personal experience but interested in trying something when I wrap my project up

    .. I was all worried about mine before I GOT it up an running .. Now 2 years later I never even notice it being loud .. Now I don't notice it being as loud as my 2000 dodge tr. If you can understand that I am used to my 2000 24 valve tr.
    ... I did not just step out of cheby gas tr. I've been in diesels truck for a while 91...93.. and now a 2000..and this farm 4BT FOR FUN MOSTLY ....

    While the prices seem high, if they have a significant dampening effect then it'll be worth it.

    Looking forward to testing results!
