Anyone venting Wastegate to Atmosphere?

Like the title says. I'm thinking about it.

Very loud, very obnoxious.

Remember how you put playing cards in the spokes of your bicycle, and how that sounded? Crank it up by a factor of ten, and that's what you get everytime the wastegate opens to vent exhaust gas from the impeller section.

Eric SS · 11-17-2001, 10:15 PM

I think it sounds cool on some cars. Anyone have a sound bite of it on a Subaru?
What if you ran a seperate pipe back to where the other exhaust exets. Nothing big and nothing isible. Would it cut the noise down?

Definitely will get the attention of the police when it vents. You have an internal or external wastegate? If it's external, route it back into the exhaust downstream from the turbo.

Eric SS · 11-17-2001, 10:34 PM

I have an external and it re-enters the exhaust probably about 2 feet after the Turbo or so

I have it vent out the atmosphear, sounds crazy,
but except the sound, what does it do?
whats the purpose of venting it out?

bsquare · 11-18-2001, 12:13 AM

Venting it to atmosphere prevents it from interfering with the primary exhaust flow.

HndaTch627 · 11-18-2001, 12:32 AM

like ben said...it keeps it from causing turbulence in the exhaust flow....VERY loud and yes VERY obvious

bsquare · 11-18-2001, 12:53 AM

Also, it will often shoot flames, so select its exit location with care

lol! you guys know me to well. At least if someone is riding my ass (Which is my pet peev) I can shoot some flames on them without installing a flameing kit like on the old detroit muscle cars

Make a muffler for the second pipe. Take a section of pipe the diamiter of the wastegate exaust. Drill a bunch of holes in it, then make a sheet metal wrap for it with enough room for some fiberglass packing material. Weld the shell on with the packing inside. Bingo mini glasspack for cheap.

63Alpine · 11-18-2001, 12:13 PM

Mine is vented to the atmosphere. Then again I have straight pipes. No cat, no muffler, I love it.

Yes it is loud beyond belief.

Kurt

subachad · 11-19-2001, 12:46 PM

Mine is currently vented to the atmosphere. It's only loud once the wastegate opens up. Not as loud as a Harley though, but still too loud.

DarkImpreza · 11-19-2001, 02:28 PM

whats the sound like if the wastegate doesn't
vent to atmosphear? cuz I bought my turbo kit used
and I think it's already vent to atmosphear
cuz it's really loud when wastegate opens
so just curious whats the sound like if it doesn't
vent to atmosphear??

HndaTch627 · 11-19-2001, 02:46 PM

it's quiet and all you hear is the BOV....most turbo kits DON'T vent to atmosphere....i dunno about you guys but there are just WAY too many cops here just itching to write tickets for exhaust noise.

Jeremy

bsquare · 11-19-2001, 03:08 PM

Yeah, I see no use for it. Of course, I don't like atmospheric BOVs, either.

Ben

DarkImpreza · 11-19-2001, 06:52 PM

is it possible to vent it back??
i mean how do you not vent to atmosphear?
i want my turbo to be quiet when I give
full boost, I thought all external wastgate
are all like that loud didn't know how to make
it quiet...

bsquare · 11-19-2001, 07:06 PM

The options are vent directly to atmosphere (essentially, the wastegate gets its own little exhaust pipe) or plumb it back into the main exhaust (where it can benefit from the sound absorption of all that extra tubing and the muffler). So, yes, eventually it gets to the atmosphere, the question is how direct that path is.

Ben

Shik · 11-20-2001, 06:49 PM

Besides the turbulence part, it's almost like running a bigger exhaust simply because the wastegate exhaust no longer takes up space in your primary exhaust, and at WOT, from everything I've read and heard throughout the years, there is alot of exhaust bypassing the turbo at WOT.

Although I've never heard a Sube dump the wastegate externally, I think it sounds absolutely fantastic on DSM cars. But to me, part of the fun of owning a turbocharged car is listening to all the cool sounds.

An old post/ feed but you boys are still influencing and thanks to Ben, my dumbass will be doing it as well***8230; with care and all that stuff
