Firewall intake???
#22
I want a quiet intake, how do I do that?
~80kpa on the highway up a long gentle slope is fcking annoying. Those carbon inline air boxes, helpful or not? I've seen FM suggest shoving the airbox full of egg foam, but I'm not doing that.
Right now I just 90 off the turbo into a 3" cone filter in front of the headlight. Was considering a inline air filer to try and quiet things down.

I'm not sure how helpful that is -- it's kind of expensive way to quiet things down.

The foam filters from Sears large shop vacs are a pretty good fit. Sears.com Cheaper in the store, but it might have just been on sale.
*Do not use closed cell foam. Duh.

Firewall intakes are on every 2nd n/a miata here in australia. Ive done them a bunch of times, including to turbo cars (smallest turbo on a miata ever incoming..)
Its definately a noticeable thing in the cabin, totally bearable and pretty cool if you like turbo noises, but from in the cabin these intakes are about as loud as it gets.

I wrapped it with some egg crate foam, that is open cell right? It certainly worked, like a whole lot. AFR and O2 range seems the same, but it's rainy today and I can't much tell if it's much weaker.
Wouldn't having to step down to the tiny t3 from 4" cause an increase in airspeed? Isn't that what makes it squeal like a piggy now?
Another of those carbon air filters, thanks for the input Dann. Think I'll have to pass on one of those now, I want to be all stealthy and quiet.

Dann, Elior or someone please post links to manufacturers of those tube airbox filter things so I can read more stuff about them. I've wanted to do this for quite some time.
I've found ONE from a company in Canada called PRM Racing but they are ******** and won't give me dimensional drawings of anything in their product line. How the hell am I supposed to figure out what to order if I don't know what will fit?

Had no water ingestion issues with my FM Randal carbon piece last fall. I was curious and after a heavy heavy thunderstorm popped the hood and checked the inside of my airbox, it was dry. The actual Randal carbon thinggy looked like it had a fine mist in it, but nothing was soaked.
