Yea it does sound off I looked all around and I don't see anything physically moving outside. I figured if that was the case it would do it the whole time though? It seems to be at a certain point in the engine warm up process. No CEL though, and it's before the radiator fans kick in so it's not the fans. The only other external moving parts is the serpentine belt and pulleys. It seems to be coming from the left side. Like maybe the left injectors or valves are doing something off because of the tune. I really don't know though. Sent from my SAMSUNG-SM-N920A using Tapatalk |

it might be okay...
So I watched your 2nd video and at first it does seem off to me.
I went and shot some vids of mine and after it got warm, it started to sound like yours. I've put about 5k miles on mine and never really listened to the engine with the hood up. I don't notice it at all inside. Other than a couple of oil leaks which have been fixed, I've had no other issues with the kit. Did you add anything else to the stg 2 kit? I added flex fuel, injectors and a fuel pump and of course a custom tune. All my installation was done by Works. Anyways, here my videos for comparison. After cold start and idling for a minute or so. https://goo.gl/photos/MMK4h25ewgFB8otY7 Here's after a quick run to get some bagels. https://goo.gl/photos/Rp2xwiPbDFZBRN5J7 |

I would suspect heat from warming up expanding metal, at 7 secs of the 2nd video I hear what your saying, weird that your OFT is white screened, I have an Ecutek setup we can use to pull logs if you need help, but I know jack about the sound, have you hooked up the OFT to another 86?

I would take a long screwdriver and put the handle to my ear while probing the motor to at least find the area which the noise is coming from.

Not sure how your tuner has it set up, maybe its the switch from DI/PORT or hybrid? Port injectors can be loud if aftermarket
Longshot, no clue what the injector strategy is on our system

Yea yours seems to do the same thing. Mine seems louder though? Maybe I'm just more paranoid about mine because it's my baby
Thanks for the videos though It makes me feel a little better. However, I am just going to wait for tomorrow and see what works says about it. I did add Perrin engine mounts, though I don't see what they would have to do with anything unless it was making the noise the whole time. But to be at the same RPM and then start making noise wouldn't suggest this as the problem. Quote:

Here is a data log. This is from about 30 seconds after startup to about a minute after the noise started.

It is completely normal. As mentioned above, it is just the sound of the car transitioning from the two injection systems.

Look at your Intake Temps! I'm on the same kit and my temps are 34 average. 51 MAX if I'm sitting at a light and it's 100deg outside.
Check your intercooler on top (only when you're 100% sure it's cooled off enough to safely check) -- Check inside and make sure coolant in there is nice and topped off and hasn't leaked out and make sure your water pump is running It should be plugged into the windshield wiper fuse and should be heard while key ON without engine on. |
