Hi guys,
Has anyone ever tried using Supertrapp style devices for a little extra silencing to sneak through IVA?
Another thing that has come to mind on silencing is intake noise. We had dreaful problems with noise regulations when i was a kid doing kart racing. We found there that intake noise was a factor, and some of the air boxes that we made up made more of an effect on the measured noise than mods to the silencer. Obviously the exhaust and intake on racing karts are fairly close in relation to one another, but, it occurs to me that they are fairly close on GT40's too.
So i wonder if anyone has any experience with this. I'm just thinking ahead for ways to make some small improvements if there is a problem on the test.
Regards,
D.
