WEISTEC VTA Valve(blow off) install
The Best of Mercedes & AMG
I'm on a FL 19 Amg S and from the looks of it the clearance I have is far less than a pre-fl. Could have something to do with the new grill or something.
In any event, this is by no means a 10 minute install as promised on the package, it took me an hour but that was due to the difficulty in removing the bolts. The only way this is a 10 minute job is if you have the front end of the car off.
On mine there was no room for a ratchet wrench/ monkey wrench. In order to remove and insert the bolts I had to use vice grips on the torx bit itself to get a right angle to remove the bolts. One the head was exposed I then used a small string to ensure the bolt did not drop down into the engine bay.
You do not need to worry about the plastic bit falling off when the 2 screws are removed - it sits 1cm into the hole that it is mounted to and must be pulled forward first to come out.
From my experience, it is noticeably louder with the weistec "trumpet" install than with just the pipe removed. Could be in my head or maybe the angle in the oem part does something to the sound.
Also, you can 100% control this with your right foot. It isn't going to blow off in comfort mode unless you really want it to.
Finally, it is super loud... Like ridiculously, giggling inducing loud.
Edit: Also, I should not that in my FL. This reduces the frankly dangerous continuing acceleration on lifting off the throttle. Not sure if any one else experiences this but basically, on 50% throttle if I ease off the accelerator at the same time as the car changese gear (around 3k rpm), the car continues to accelerate. While this is somewhat expected because due to the nature of how a Automatic Transmission works, the vast majority of this was occurring due to the excess turbo charged air being recirculated into the intake manifold. One practical benefit of the VTA is that this effect is now minimal.

would you happen to have a video of the renntech BOV install ? I just got mines in and have no clue on installing them

is it a subtle mod or did you guys ever think it was obnoxious after getting it?

Also, is there no hazard of having the lower section wide open for debris or whatever, whether it be with the weistec piece or if you leave the stock piece on but open (I get that, that isn't the intske side of motor going into the turbos).
