Just trying to get a list of pros n cons of have open wastegates VS recirulating them. I am getting ready for my Greddy TT build in a few months and trying to decide which to go with.

For those with Open dumps, do you get tired of the sound? Who makes 3" or 3.5" downpipes with wastegate relocation kits?

 

Alot of people I've talked to liked the sound of the open dumps at first, but grew to hate it and wished they'd never done it.

 

I love the sound of open dump!! I guess it could get old after a while tho... O well we'll see in a few weeks

 

Open dumps are not for the weak of heart...maybe the weak of hearing. They make an improvement in spool and are less restictive, potentially freeing up a few ponies. They get louder as you add more boost. At 6 PSI they are pretty mundane but 9 psi and above they can get pretty loud. Its all relative though, but if you like the volume of your HKS I would say you are NOT going to like the volume of the Open Dumps (2x louder at 6 psi 2.5x+ at higher psi).

 

open dumps sound bad... like a lawn mower on crack. people would ask is there something wrong with your car?? Plus, it drowns out the turbo spool.

If you recirculate your dumps 18" down from the turbo with a smooth transition, you won't have any power loss as you would if you had it recirculate a few inches from the turbo at 90 degrees .

 

I love my open dumps, they are not bad from inside the car, from outside its ridiculously loud which I like.

 

Trust me on this,berts open dumps(right in my fuking ears)sound awesome.
Soon to have a little something for you bert.

 

I'm currently running 17.5psi daily and open dumps from mid 3rd gear, full throttle to fourth gear full throttle sound effin awesome .... and will scare the crap out of any seasoned racer who is not expecting it ...

BUT, low rpm 5th and hitting full boost with the rpms building so slowly sound terrible ... I've learned to part throttle it to avoid going above the wastegate spring pressure.

I do want to get rid of my open dumps cos I really can't tell if I get any detonation at all .. and this is dangerous ...

Definately very loud. With time, they will not sound as loud, as hearing loss sets in.

Usually, boost stability is improved, and backpressure is reduce slightly, so expect a mild power improvement as well.

 

It gets old, I am looking to recirculate them back in

 

i love it!! it says "yes, i am badass *****!!"

 

i seen vids of TTzs claiming to have dumps and it sounds normal to me...would anyone have any nice vids?..

 

How could I have guessed that you would like open dumps

 

PF loves open dumps..

Just ask AJ. He kills it and makes it known on the street

They sound amazing and are very intimidating.

 

Wussies.... Open dumps ftmfw! lol.

 

Real men just run open downpipes

 

sharif,

What happened to your greddy downpipe/ wastegate relocation pipes? ae you selling them yet?

 

Ummmm, yeah, that was computer generated...

btw, before anyone asks, I wasnt holding the camera, the passenger was...

 

I'm still undecided on whether I wanna run an open dump on my daily driver... jeremy obviously thinks I should haha

 

I never heard your open dumps, I only hear a little bit of the exhaust as you take off in front of me. the supercharger and nismo exhaust kind of cover that though. guess i'll have to get next to you with the windows down and listen.
