Symposer Defeat
#101
Meth setup
boost reference line is circled in green. It’s super dusty
4 port direct meth injection. Snowperformance stage 2E system with a solenoid + prometh distributer and nozzles. Boost reference is tapped on the sc plenum and lined through the steering column to the controller on the dash
lol. Cons of living in the middle east

The Symposer sets no codes regardless if it's hooked up or not.
You can disable it anyway you like.
I just unhooked the tube going to the cabin and plugged it. I left everything else in place for now. If and when I pull the blower I will neaten up that area and remove excess the parts.

Yes it's just so buried at the back of the engine. When I saw a picture of the engine out and all that is involved with the Symposer I just kind of backed off and plugged the tube.
Yea it's worse for you F-Type guys because the hood opens backwards and the Symposer is right there. On my XJ the Symposer is WAY in the back so you got to know where to look to even see it!
If fact I am embarrassed but when all this Symposer stuff started getting talked about I was sure my car did not have it because I had never seen it when working under the hood. I had to look at some pictures to find it.

I don't know but the F-Type has the reverse opening hood so the Symposer is all out in the open compared to the cars with front opening hoods. I know on my XJ that getting to the Symposer requires laying on top of the engine and getting back under the cowling stuff.
You can can get to it but it does take a bit of work!

For future reference this is the size of high temp silicone plugs that will seal perfectly. The opening is 16mm in diameter.
you will have to cut them as above. You can actually use either part to seal. The plug bit will need to be cut so only 2mm above the rim of the hole and it goes down into the hole or use the top flat bit sits on top of the hole but is compressed and seals the hole anyways when you fit the connection back together .
It makes a big difference to the sound levels inside the car. A lot quieter even under acceleration. Actually too quiet for me

I wonder if you could use a plug with a hole in it to limit the sound without killing it all together, for those who still want some pumped in noises? Or possibly just use foam in those instances.

Thanks for showing the size you used - I'm going to replace the foam I used with a solid plug. I'm fine with some further reduction in the cabin noise.

I just put a silicone plug in as is shown above. It feels like a "cleaner" solution to me since the only foam I had was not able to be fitted as tightly as your pictures show. I won't know til morning if it makes a difference.

After replacing the foam I originally rolled up and stuffed in the pipe with a tight fitting silicone plug, the results are pretty dramatic. With the foam I still got engine noise in the cabin through the symposer - it was quieter than without, but still evident. With the plug, the sound is completely blocked and the result is a much quieter cabin and (for me) a nicer driving experience.

VAP now has one you can buy. I just installed it. Sure, I could have saved a little by fabricating something, but had not found the time to do so over the last few years. I was happy enough with the defeat that the delete just dropped down to the back of the priority list.
