Hey Guys,

As the title states, it's going to be a video about how to let your engine breath better as well as a little giveaway at the end of the video! Hope you enjoy and have a fantastic weekend!

Nice vide, did the K&N as well, I looked into removing that little door, but have not gotten around to it.

I could not find a way to safely remove it without busting it off, so i figured i might just tape it as a temporary solution.

Yea, how much of a difference did you notice? I'm looking at how to retro fit a A7 supercharger onto our motors lol.

Difference is not really that much, i want to say it's more than it actually is because i think its just a placebo effect... But it does feel a little preppier.
 
Patrick,

If you want to keep the the little door open I will try to explain what I did on my 2016 3.8 and my new 2018 3.8.
I think it made both a little more responsive at low speed but didn't effect MPG any at all.

If you look at the bottom edge of the door you will see a small cover. I can see it in the video partially covered by your
thumb.

There is a small magnet in the door under that cover and another at the bottom of the box. They hold the door closed until
there is enough airflow to open the door.

If you carefully pry out that cover you can remove the magnet, turn it over and reinsert it and snap the cover back into place.

Now when you let the door go back down the magnets will repel each other and stay open some.

Now we have the door open but it can be back to normal just as easy as it was changed. No parts to replace or loose.

Oh sweet,

Thanks for that Tip!!!
 
What is the trade off in keeping the door open all the time? I'm assuming some engineer came up with the design to hold it closed magnetically for a perceived good reason. Will it make a difference in very cold weather?
 
I've seen someone post on my video that there should be no trade off at all, the only thing i came up with might be more gas used. But again, not sure exactly if that will effect gas milage that much!

Yea, I don't see them adding something that increases cost ( although not a lot I'd guess ), and hinder performance, without some good reason.

I'm sure, there is some sort of reason to it, but, i'm not exactly sure what that is...
 
I agree, There had to be a reason, but I have no idea what it could be. Emissions at idle maybe, emissions when accelerating from low speed, a smoother transition from cruse to accelerating.
The list could go on and on.
I read about this in the Gen 2 section I believe. Some had a problem of poor throttle response when accelerating from low speed. Some found that the problem went away when this mod was done.
I didn't have the problem with my 2016 3.8 but I did the mod anyway and could feel an improvement in response at low speed.
I did the mod to my 2018 3.8 and could feel the improvement also.
MPG didn't seem to change on either car when the mod was done.
I don't get any check engine lights so emissions have not changed enough to be out of normal range.
So, who knows? I sure don't.
 
There was an earlier thread about this. I noticed small input throttle response improvements and it was real boost to "feather footing" from an ergonomic standpoint. Didn't notice any change in MPG. No way that magnet can work properly since the engine controller has no idea what it's doing.
 
So far i have not seen any decrease or increase in my MPG either, but it's nice that it's a little more responsive on the lower end of the RPM's.

P.S. don't forget to subscribe for the giveaway! :)
 
I firmly believe that the flaps are there to both "smooth out" power delivery and quiet induction noise. Just think of what the target demographic are for these cars... I took both of my flaps off the day after I got the car home. It made a very noticeable difference to the engine response.
 
I could see that, specially with the noise, but the power... maybe as well, but i don't think they would make THAT much of a difference for people to complain, if anything they would probably enjoy it more, since this heavy car needs a little kick in it's butt once in a while :)
 
Trade off was less engine noise into the interior. Until over 3000rpm the door will stay shut and air comes only from the rams over the radiator. Limits air flow drastically but keeps engine quiet. Taking one magnet off lets the door slightly/lightly close but as soon as you give throttle the vacuum will open it up and get more air into the engine at low rpms. You will find it slightly more responsive. Other things to do is be aggressive with the rpms and the computer will readjust to its maximum settings, same with shifting program; then get rid of the 2nd cats. Really hinders exhaust flow. Can pass emissions with out them. Aftermarket sells easily put on straight pipes that fit exactly in place of cats. You get a little more umph and hear a little more engine growl. Sweet. We've tested the K&Ns on dyno and a clean regular filter gives almost same reading. Infact surprised that even with out any filter and open box only 4+ hp more was noted. One of the engineering guys said the surface area of K&N and quality paper filter have same sq "s but the K&N will make more noise and have bad problems if over oiled.
 
Hey Roc,

Thanks for that, and interesting to see about what you mentioned with the K&N air filter! i would have thought it would pretty much produced the same output power, but it's interesting to see that completely removing everything would only grant 4HP. I was worried at the beginning that i would screw things up with cleaning and or oiling it, but honestly, you get the hang of it after a while.
 
what's the numbers with the secondary cats removed?
