oh...you can only tell a difference under high boost. ie. 10-12 psi

 

if you are worried about **** getting in your engine, why not just buy a true BOV?

they do make fake BOV's ya know...

 

it doesn't work as stated....perhaps you did something else and do not realize it?

 

then it probally only works if you have the 3 foot pipe (or however long it needs to be) running to the outside of the car.

how much louder does it make it by putting it closer to the Y-pipe?
is it safe?

 

I wasnt thinking of getting it closer to the Y-Pipe, I was just fiddling with trying to change the pitch of the sound that the air makes when the BOV opens. I just cant see how putting hangers around it would make a difference. I even tried it, however with two instead of 4, and it didnt seem to make any noticeable difference. An extra hose? hmm. that may do it. Almost seems like too much work for not a whole lot, but hey, I got time, and simple arts craftsmanship, and puttin those two together might make something completely worthless that works.

 

i pierced the oulet hose with the hangers, no sound change

 

throw a whistle tip on there! they go WHOO WHOOOOOO

 

ok hmm what did you guys use to plug the hole in the air box ? any pics of your set up on that. ?

 

wine cork

 

use a 20 oz bottle cap and zip tie it or hose clamp it.

double-sided tape rolled into a ball (against itself) also works.

 

hmmm wine cork?.. and a 20oz bottle cap...
i feel like a DSMer now... seriously now..
i wanna see some damn pictures!

 

u actually drilled holes in the end of ur BOV outlet, and still no sound difference? wow. I would have guessed that holes would have done it. And yea, A bottle cap is what I'm using. Or u can get a rubber stopper from home depot for pretty cheap, and just plug it.

 

no, the short hose that comes off the BOV, drilled holes in it, put the hangers in....nothing

 

i cant believe this is an actual topic of discussion. this proves that the 3rd gen section is worthless anymore thanks Vin

 

A 16oz arrowhead drinking water plastic bottlecap slips over the airbox nice and tight. No zip-tie needed. A cork will rot and pieces will get sucked in eventually.

 

ok, Im just trying to have a little fun without having to pay. I'm also trying to deny that my motor is having problems, and all I've ever done so far is preventative maintenance, so a little free mod like venting and changing the sound somehow just makes it interesting. I am super low on cash, and need to start saving for a rebuild, cuz I know the day is comming soon. So, in the meantime, who's got a real idea on how to change the sound?

 

how can you drive an rx7 and not know where the BOV is?

 

i am glad someone is with me

 

attention FD owners: your car (rx7) has a rotary engine and two turbos. this thread really sums up the 3rd gen section for me. wait... did most of you guys buy this car because it looks cool?

 

the only way you're going to make your bov sound "different" is get a new one. hell, why dont you stick a referee whistle onto the outlet of the BOV (attn. thats where the air comes out) so your car will whistle like a ref every time you let off the boost
(PS. thats when the BOV makes its little noise is when you let off the boost...)

 

nah, I disagree. I bet theres some way to change it other than putting some kind of dumb *** whistle on the end of it. Air splitters or something, similar to the HKS? Of course, getting a new one would be nice, but spending that kind of cash isn't nearly as good as spending it on something for reliability at this point.

 

I think this is what JhnRx7 means...

This will make it understand easyer, I hope !

 

NO idea what the squiggly lines are...

 

the squiggly lines I believe are bent coat hangers....so what would u use for the hose? Thx for the diagram.

 

and u just take the coat hangers and zig zag 'em up??? why 3 feet of this hose? I would assume this is for the sound, but that seems a bit much...
