My 22 eco 2.7 is loud as fuck without the silencers and the VTA mod. Literally sounds like a diesel truck spooling up now😂 My wife heard me coming through our neighborhood 1/4 mile away👍🏻🤙🏻
Those are NOT turbo silencers, they help spin the incoming air for faster spooling, some dingbact said the are silencers and everyone with a RU-vid channel jumps on it spreading the bs
Yep. I think they actually call them vortex generators. But a lot of people have reported being able to hear the turbos more, and I’ve had no adverse consequences. No doubt less turbulent air flow, while better for efficiency, also decreases NVH, but up to the individual user if the juice is worth the squeeze so to speak. Plus it’s easily 100% reversible.
The hot side compressor is the only place anything matters. If you think swirling inlet air before it hits the cold side wheel does anything you're mistaken.
They do help spool faster, but by STOPPING air rotation, so that the turbulence is eliminated where the intake splits. Otherwise the vortexes from the turbos would travel backwards up to the intake split and then turbulence and resistance would result.
A small cone filter with metal top makes it sound a lot better than open tube. Trust me I did it today and listened to it both ways. With filter it sounds so much better. Like I said, I used a small filter similar to a cold air intake filter. It spanks !
So as many have said these are not T silencers they are velocity collars. Also the a T does not recirculate into the intake just for recirculation is slows the rpm of the T bearings as so you don't slam on them. These were designed for stop and go everyday commuting not racing.
I know some people could never hear theirs. I always could, and can hear them better now. And then the VTA is an obvious difference. But none of it’s meant to be too serious. Just an easy mod for fun. Sorry it didn’t work out for you, but thanks for watching.
Correct. If you do anything, you can put a small breather filter on to keep dirt dobbers out something out, but you don’t want to cap it. Otherwise the excess air pressure can’t vent.
I just did this mod on my 2018 3.5 and removing the “silencers” definitely made the turbos louder but then when I did the blowoff valve mod I can barely hear the whistle now. Did this happen to anybody?
@@GooseAutoWorks I ordered a cap for the other pipe. Just wanted to test it by using tape lol. Maybe that is causing it. Will try it again once I get the correct cap fitting for it.
I know that some people say they can’t hear their turbos or can only hear them on hard acceleration. I’ve always heard them clearly. Especially now. Im not sure what the difference is.
I did indeed. I thought about that afterwards. I just tuned the truck though so I’ll do a before and after for that or something. Sport mode definitely makes a big difference for acceleration! I like it 😎
Sorry. I replied yesterday, but I don’t see it on here now: Correct. If anything you can out a small breather filter on the BOV to keep dirt dobbers and stuff out, but don’t cap it off, otherwise there where be no where for the excess pressure to vent.
I think it’s pretty much the same. The layout may be slightly different, but the method carries over. It doesn’t improve anything per se. It’s more just for fun; to hear the turbos spool better and to get that audible blow off noise. I personally love it and have had zero issues at all since doing the mods.
I’m probably over thinking this. But….. by unhooking the dump valve to the intake, in my theory it should over all allow cooler intake air by not recirculating and or releasing the hotter pressurized air into the intake. Most likely minimal if any difference, just my thought.
@@GooseAutoWorksit has to be higher it’s inevitable. By design turbo charger air is higher due to running through a mechanical device that uses hot exhaust gases to function. But like I said the difference in the intake would be minimal at best
@GooseAutoWorks found another vid and a comment that said after '20 they stopped installing them as a cost savings and they are negligible on performance 🤷♂️
I took mine out and unhooked the vta and put a filter on it..nothing really but a cool little pshh when you let off i recommend hole in bottom of intercooler so it can drain or just get a new truck
No. The “silencers” are basically just for NVH. The VTA just makes the diverter valve act as a blow off valve. My fuel economy hasn’t changed at all and it sounds a lot better in my opinion.
Not that I’ve noticed really. It’s actually gone up about about half a mile/gallon, but I attribute that to me trying to get better mileage with my driving habits lately.
Hello. So those systems don’t really overlap. My catch cans still collect oil blow by. The plumbing removed from the diverter valve puts it back into the intake pre-throttle body. The lines that carry oil blow by come from the valve cover and crankcase.
