Sound generator mod possible with a supercharger?

minmat11 · 11-09-2015, 09:18 PM

This might be a stupid question but I need somebody to confirm this for me. I have an ESS S/C on my E85 and was wondering if the sound generator mod was still possible. Since the S/C uses an intake bypass, the generator won't connect to the elbows anymore. is there another way around it? i really wanna get this done. Any help will be highly appreciated!

Here is a picture.

No not possible.

Even if you'd made a connection with the sound generator, the pressure from the supercharger could blow up the internal membrane from the sound generator and that would create a huge leak...

If you use the open grommet (or no grommet at all) it lets in a little bit more of the supercharger whine which is also nice.
Do you still have the original grommet in the bulkhead on which the soundgenerator connects or do you have the closed grommet installed (from the lower models that don't have the sound generator).
I see you already have an open air filter, so the whine on open throttle will be substantial then.

I use that "grommet" for the sound generator to feed the wiring through for my aux gauges

No, not possible. Your sound generator would go from suck to blow.

And you'd no longer be able to go to ludicrous speed!
