Hi 986ohama,

thanks for the hint. What i found is that: Finally: Dyno charts of de-snorked 986S!!!

Because i couldn't see the graph i color corrected it.
red = with snorkel
violett = without snorkel

The biggest hp difference is above 6.000 rpm. Not the rpm speed range i'm often.

There is a difference in torque. If you look very careful you'll see a loss below 1.800 rpm. That is a rpm speed range i'm often.

I think if you really want more sound from the air intake i think you'll have to redesign the snorkel in a way that it looks like a trumpet.

Regards, Markus
