open dump pictures?

[eclipse_16g]

can someone show me a picture of what an open dump would look like?

you mean an o2 housing vented to atmosphere?

the os housing on my car doesnt have this. but when i baught the car the guy gave me one should i put it on the car what are the benefits?

bad ass roar noise when u hit full boost =)

Ehhh, its more for aesthetics and sound. Wont help with creep or get you any more power (assuming this is for an internal gate). Same difference as venting BOV to atmosphere if you are bent on drawing attention.

You can only run a dumptube if your turbo hs an external wastegate. I'm running mine off the exhaust manifold and welded the dump tube to exit the side of my bumper.

Negative. Punishment Racing makes O2 housing that dumps for internal WG as well.

Negative. It actually helps slightly with boost creep. Instead of recirculating back into the exhaust where it is full of exhaust gasses and is restrictive, it dumps into the atmosphere which is not restricted and no exhaust gasses to encounter.

Don't compare this type of housing to venting a blow off valve. This item can actually HELP the performance of your car rather than HURT it.

You're incorrect in assuming it will not help with boost creep. This type of housing offers a restriction-free route for wastegate gases to bypass the turbine housing- even the best-flowing exhaust system on the market cannot duplicate this type of flow for the wastegate gases. If you're having trouble with creep, one of these housings combined with a properly-functioning wastegate actuator is the solution.

 

[kahl23]

In addition to the creep issues dumping vs recirculating can supposedly give you more power. The theory behind it is that most recirc'd O2 housings have the wastegate passage rejoining the main exhaust stream just past the turbine at a fairly sharp angle, which is thought to cause turbulence and hamper flow through the turbo and out the exhaust. This was argued a few years ago, but I forget if there were ever any conclusive dyno sheets showing what exactly recirculating left on the table, if anything. I think this is probably true for a poorly designed O2 housing, not sure what effect it would have on some of the better made ones. Myself, I'd rather take the performance hit (maybe) of recirculating in exchange for a little more civility.

Project2G, how do you get away with that open dump out the front bumper in Cali?

On some cars, the O2 dump sets off the knock sensor and pulls timing, making the car slower...

Sorry guys - I thought these dumps for internal were garbage. If you were having problematic boost creep would you spend the money on one? With 3" exhaust setups, I would imagine boost creep reduction is negligible or a great theoretical topic. If you dremeled out the housing for the waste arm, cleaned up the opening deal and put one of these guys on - sure? Other than that I think they are more for 'look at my car' points (like a vented BOV). Honda guys with euro tails and carbonfiber hoods would put this on in a heartbeat.

hahaha I just watched your Youtube video..

project 2g i really want to do what you did where it dumps out the side of the bumper...sweettt

 

[talonalex92]

Mines been dumped out my bumper a long time. Check gallery for pix. Its been like this a good 8 months.

Unless you have a T25 or a 14b or even a 16g, a dump will not blow open. Almost nobody knows I have dump since the only way I can spool my turbo is on the highway or long stretch of roads that don't have traffic lights. Even if I spool it, it begins to dump at 10psi.

I'm sorry I don't follow, what do you mean blow open?

That's interesting....the turbo in the pic I displayed is a Frank Level 5 20G on my buddy's TSi AWD. That dump doesn't make a sound until 22psi is made, and when it does open you know it.

If yours begins to dump at 10psi, something's wrong with your wastegate actuator or the way the flapper's sealing. You shouldn't hear any exhaust coming out of the dump tube until you've reached your target boost level.

Man I was going to get a O2 dump but my friend has one and he said it's loud as all hell.

 

[GSX_TC1]

I put a cheap lil o/2 dump on an oldschool godzilla turbo (20g) and i remember the first day i had it i was like Dam! I love this! Haha it was soo badass to me bcuz once it hits full boost it just screams to redline. I just didt like how dam close it is to my alternator though.


I like these dumps.. This is my Dream setup rite here guys..

 

[Ajax]

Now that is pure sex!!!

 

[Captainredeyez]

Oh My Goodness!

 

[ali]

drool that is sex

 

[JusMX141]

Shearer had a similar setup on display at the DSM Shootout a couple years ago. Those guys sure can build some sexy manifolds....but they better rotate the center housing of that turbo so the oil supply inlet isn't on the side!
