i hate it. It's the hks ss it makes no noise all i can hear is my wastegate. Is the hks ss just not that loud? I love the Greddy type-s my friend has a bone stock gst all it has is the type s and his is loud as ****. Is it because it is a rotary engine or because the hks is just gayyyyyy.

 

Should have gotten a turboxs. Damn is it loud. Louder than my friends blitz pushing 15+psi by quite a bit.

 

blitz bov's sound awful i have heard the turbo xs didn't like it it was just like the blitz but alot louder.

 

if your wastegate is external vented it's loud as **** and no BOV will be louder. but they are at different times. you should hear the BOV between shifts. the wastegate noise happens when you on the gas in boost.

 

it a turbonetics vented external wastegate and no the sound comes when i let off the gas not when i get on it.

 

I cant say the same about mine, its loud as hell. Maybe you want to try backing out that little bolt on the back of the BOV, that may help.

 

LOL maybe what you think is the wastegate noise is the BOV LOL...

the wastegate will make noise while you are on the gas. the BOV makes noise when you let off.

 

Yea dude a wastegate sounds like someone just ripped of your exhaust off. Its not a hissing sound or anything like that.

 

mmm exernal wastegate

Omg that sounds amazing. Do all external wastegate's sound like that?

 

 

It DOES sound like an airplane.

 

no actually it's my wastegate because it made the exact same sound when i had my stock bov now there is a barely audible whistle then a fluttering sound when i let off the gas.

 

no actually it's my wastegate because it made the exact same sound when i had my stock bov now there is a barely audible whistle then a fluttering sound when i let off the gas. before it was just the fluttering sound

 

my type S sounds very intimidating =)

 

it says in your sig that you have a type r i want a type s sooooo bad that's what i ordered originally but the flange wouldn't fit on the piping so im prolly going to get bigger piping and get the type s put on.

 

i have a type S, i have to change that.
i have heard type R's, and their bad *** too

 

i heard type- r's are very quite. Like it's driving me crazy that i can't hear it.

 

RX7withNitrous, it is not your wastegate

It is compressor surge, it is the sound of air going back through the turbo. Basicly your BOV is not venting anything, or not 'enough'.

 

y isn't it venting anything?

 

Do you have a nut on top of the bov? Try backing it off a bit.

 

and y did it make the same sound when i had the stock bov?

 

do you have the vac line pluged into it?

 

there is a bolt on the back of it ya i don't want to unscrew it too much and have it come out. Is there a spring or anything that could fall out if i took it out too far?

 

Quite possibly the T04 was flowing to much air for the stock bov to vent.
