That'sa quiet turbo & BOV
I got my '90 TurboII installed with the new S5 J-spec engine, and the turbo is incredibly quiet, and I can't even hear the BOV going off when I let off throttle (but the boost gauge does go down to negative when I close throttle)
Anyone else notice this on their TurboII? Is it normal? I was riding in my friend's Eclipse GS-T yesterday, and you can hear the turbo spool up pretty loudly, and the BOV is pretty loud too. I just love the sound of a spooling turbo, it's one of the reasons I got the car, but I don't hear it. Any suggestions?

Most people don’t want to hear those sorts of noises when they buy a new car, so manufacturers do a lot of work to make sure they can’t. It’s just the small bunch of weirdos like us that actually like those noises...

You couple a check valve to it since otherwise it will suck unmetered/filtered air in. I made my check valve w/ a JDM plastic bevarage container neck/top, a rubber suction cup and some elastic. Worked great, sounded great and looked ghetto in that special JDM/drift way :-)
Others use a checkvalve from the hardware store.
Mazda calls the BOV the Air Bypass Valve.

hey Jimmy, is this Banzai Racing place near us? And do you have pictures of your TID mod? I bought my car with a TID mod, but the hoses are starting to crack and I need to replace them.

Pirana, PM me if you want my number and we can meet up sometime. We are only about 10 minutes from each other.

So a 3" TID, cone filter, and say a Apex Dual Chamber BOV would make a nice sound? I am trying to get a TII, and I really wanna hear that turbo sing!!

Remember: This TID yields a 1-2 PSI increase so an FCD maybe necessary to avoid fuel cut, depending on your current mods.

you're saying the ECU can't handle the programming to force enough air beyond 8.something psi of boost? So if it reads like for example 500 ci of air at 8 psi, it can't handle enough fuel for 600 ci of air at maybe 10 psi?
