zeindog Posted July 22, 2009 Report Share Posted July 22, 2009 Did some research today when I got home and this is what I found. The large muffler looking piece shown below in the intake track has a baffle in it. What I did is first removed the muffler as I will call it by loosening the clamps around it. Heres what it looks like from inside. On the bottom of it was a patent number, which I looked up and came across this document here: PATENT FOR INTAKE SILENCER Next, by looking at it from the front which has the two indentations on the top and bottom where it is plastic welded, I just stuck a flathead in, pried up and the baffle slid right out. Baffleless... I installed everything back on, went out for a test drive with no issues. I could notice the supercharger whine more when hitting the throttle while in neutral and when easing into first gear. I didnt have enough road around me to really let the baby rip, but I also have muffler deletes so they were screaming so thats all I could hear. Im going to see if the filter from the ford svt cai fits also and if that makes any difference too. Simple enough mod, and its free! Link to comment Share on other sites More sharing options...

SmellSoGood Posted July 23, 2009 Report Share Posted July 23, 2009 THanks for the pics. I read an article on the exhaust and whine silencing they did. There were some drawings as well, but I think they were removed from the Internet site that hosted the detailed Autocad article. I specifically remember them talking about reducing the SC whine by blocking the sound (I thought it was a box or something). As for the exhaust and interior noise level that has been reduced, SVT wrapped or encased a piece of the exhaust or body to exhaust with some additional insulation or resin stuffs. Not sure. Thanks for the pics. This will be one of my first mods. Link to comment Share on other sites More sharing options...
KingCobra666 Posted July 23, 2009 Report Share Posted July 23, 2009 Hmmm, all be danged. Ford obviously doesnt know we LIKE the whine Any chance it could change the A/F mix? Looking at it I doubt it highly, but maybe somone that actually knows could chime in. KC6666 Link to comment Share on other sites More sharing options...

ingram4868 Posted July 23, 2009 Report Share Posted July 23, 2009 Isn't that something. They take the GT and install a pipe to the cabin to increase the sound and the GT500 they quiet the sound. Link to comment Share on other sites More sharing options...

I had to pick my old car up from the dealer since I left it there during delivery. My dad drove the Shelby while I followed him. The car sounds great when you're outside of it.

I agree--i was parked in a lot near a big road and a red 2010 was at the light.When it turned green he went thru the gears and it sounded great,much better than when youre in the car.I will take out the baffle.BTW, I think from an engineering viewpoiint, they just deadened the sounds by baffling,it shouldnt affect the airflow,just the sound waves will be reduced in amplitude,unlike a muffler,that actually deadens the sound waves.

stevenh Posted July 25, 2009 Report Share Posted July 25, 2009 The only problem with this mod is it looks like you will get a lot of dirty non-smooth flowing air if you simply take out the baffle. Stock, the air runs down a similar size channel from the air cleaner into the throttle body, but when you take out the baffle this part of the intake chamber is now a lot larger in diameter so the air will get "caught up" in this part of the intake before it goes into the engine. I pulled my baffle out and there are no sensors attached to this part of the intake and it does not block or restrict incoming air (hence no retune), and all that happens, according to the patent description, is sound waves (the whine) coming back from the supercharger just get caught between the baffle and the outside diameter of the housing. I simply pulled out the baffle as the first post described, wrapped the outside of the baffle with duct tape to plug the holes and reinstalled. It takes all of about 5 minutes. This way the intake diameter remains the same throughout the entire length but the sound now does not get caught in the "muffler". I can tell no difference in performance, but the whine is now more pronounced. It is a alot easier to just do than the post sounds, and if you don't like it after you pulled it apart just put it back together and it remains original. It is literally just loosening the two hose clamps, pulling that portion of the intake and reinstalling. It will all make sense when you pull it off. The aftermarket intakes won't have the baffle so they will all sound like the 07-09 does. Link to comment Share on other sites More sharing options...

Sure would not want any even small, minute pieces going in to the engine. I have mainly worked on aircraft engines all my life and I would never put any tape or anything else inside an air intake.

alaska Posted July 25, 2009 Report Share Posted July 25, 2009 I wonder if he means actual duct tape used on exterior ducting that is made of aluminum and is heat resistant? Link to comment Share on other sites More sharing options...
sharabi Posted July 25, 2009 Report Share Posted July 25, 2009 From second pic/last pic the diameter seems to diminish after you removed the silencer, is it only the angle at which the photo was taken or the side wall is softer now without the support of the silencer, if the latter would that collapse more under the negative pressure when sucking the air in?

blkGT500nCA Posted July 25, 2009 Report Share Posted July 25, 2009 I wonder if he means actual duct tape used on exterior ducting that is made of aluminum and is heat resistant? Either way, you gotta love a 2010 GT500 with a taped up intake. Just get a JLT. Link to comment Share on other sites More sharing options...
stevenh Posted July 25, 2009 Report Share Posted July 25, 2009 BLKGT500 is right, the way to do this is with a new intake. I just tried it, when replacing my intake just to see if it would work since guys were asking about it. I used the aluminum "tape", which isn't really tape and becomes a permanent bond. It also is completely hidden inside the canister and can't be seen. The muffler is made of plastic so you could also just sleeve it or epoxy the small holes as well. Just in case you wanted the whine without doing anything else. Link to comment Share on other sites More sharing options...
ingram4868 Posted September 3, 2009 Report Share Posted September 3, 2009 Make sure the rubber around the muffler is rigid and does not partially collapse at WOT. That engine sucks a lot of air. Link to comment Share on other sites More sharing options...
