Default Who makes a EWG kit ofr the VF39 that re-connects into the downpipe?

I'm looking for a complete kit that will allow the EWG setup to re-enter the exhaust stream in the downpipe. I'd like to go EWG for the spool/power/response but don't want that wastegate dumping sound.

I know Helix and Grimmspeed both make kits but from what I've seen, neither have a downpipe with the kit that will connect the WG to them. So do I have to cut and weld or what?

Thanks

F the EWG setup. Do what I am going to do, throw in some meth injection, will do WAY more

But I don't know any off the top of my head...most are atmospheric.

I figured more is better so I planned on doing meth as well as the EWG

Sorry man thats a custom request. Anyone that makes a turbo kit with Up/Down will , accommodate your needs, I should say any good vendor will. Your going to get more than if you kept IWG . I myself like the idea of plumbing back in but the gains are far less than 100% EWG.

So is it worth doing EWG at all if I'm going to plumb it back into the DP?

Yes if you hate the raspy EWG as I do plumb it back in keep a big Spearco TMIC and you'll get the spool. You might want to kick the 39 for a 20G though you will love it.

I'm thinking of kicking the 39 for a Dom 3.0R .... but not for a year or more.
So I just wanna maximize the 39 for now.

I was going to grab a 20g...but for the price n all, I think the vf39 with meth inject will do just fine

Turbo is cheap to replace if anything happens. don't have to worry bout injectors and EWG setup

Only thing is 39 runs out of steam up top. But it will be GREAT for what I want, the corners

I agree with this train of thought - lots of mid-range, as my car will be a lot of Auto-X and HPDE but first and foremost will be a STREET CAR/DD.
So I'll take mid-range on the VF39, over a big turbo with a little less mid but more top-end.

You want to re route it back in as far away from the turbo outlet as possible. You dont want it dumping back into the downpipe 6-8" from the turbo. You lose 90% of the gains of an EWG when you do that, leaving you with little more than (much) better boost control.


One of the big ways an EWG helps you make power by effectively reducing post turbo backpressure by reducing the volume of exh gasses that have to make their way through that pipe. When you route it back into that pipe, you lose most of that gain, and worse, you cause huge turbulance where it comes back in, which is aweful for flow, which also reduces the gains and effectively raises backpressure. This is why you want to put it back in further down the pipe, and at a very gentle angle.

Pick up a copy of "Maximum Boost" by Corky Bell, it goes into great detail why routing an EWG back into the exh is a bad idea, and how to minimize the negative affects if you have to do it.

Suffice it to say that routing it back in, that close to the turbo, and at a 90 deg angle, is the worst possible way you can do it. Seriously, Its an aweful design. Even moving that entrance 6" further down the pipe, and bringing it in at a 45deg angle would be 10 times better for flow. Best case scenario you would want it re-joining 24-30" down the pipe at a very gentle angle.

Just go buy a "Twin Dump" dumppipe (x-force, ces, etc) that has a separate pipe for the wastegate gasses that joins back in at the end of the dump pipe.

Then modify it - cut shut the top where it joins the flange and join your ewg outlet pipe closer to where the "twin dump" wastegate pipe joins back in to the dump pipe. It should be a simple mod for an exhaust shop or a few hours job for a home modder with good welding experience.

It is much easier to understand what I mean when you see a pic of a "twin-dump" dump pipe - the following image is of the CES "twin-dump" dump pipe. The x-force is separated even further, but I could not find a pic on the net.

THAT would actually really work well. By the time you do that work you could have just done the same to an HKS downpipe and a normal EWG setup.

But that pic shows exactly how the re-routing should be done. Far enough down the pipe, and a great angle.

sorry, that wouldnt work well at all.

take your turbo out and look at the direction your wastegate will be opening up.

DIRECTLY INTO THE DIVERTER FLANGE. = no good

Your wastegate never actually fully opens. Thus your not going to get the same effect as a true EWG or even Bellmouth for that matter.

Clearly that went over your head. They're talking about taking that downpipe and modifying it so that your EWG plumbs into the divorced tube.

I'm with Davenow, though - that's not going to save you much time or effort over just plumbing your EWG into some other (cheaper) non-divorced downpipe.

Ahh, i see your point of view.

I think it would be way cheaper to buy an HKS downpipe, and mod it to have flange coming off it for the EWG.

Buy any EWG up pipe
Buy an HKS downpipe

Have them make the dump tube go down to the bottom of the downpipe and route back in like the twin pipe in the pic above. That would be the best way. (obviously you could also just mod your own up pipe to go with the EWG instead of buying one)

Shouldnt even cost that much other than the EWG itself (those are expensive little buggers!)

The main point is to NOT route it back in right after the turbo, especially at the 90deg angle all those kits do it with.


And you would be suprised, those twin dump downpipe actually work ok. Not really any better or worse than a bellmouth though.

Heck, the HKS downpipe performs 90% equal to the best bellmouth DP out there. True story, seen it lots of times.

just buy the ewg/up-pipe combo with dump tube from grimmspeed and call it a day. For $570 i think its totally worth it. Im ordering that setup at the end of the week for my STI. Im going to be running that setup on the VF-39 + aps 3.5" turboback, prodrive BCS and accesport, car is going to be a beast. Have plans for more mods in the future but for the money i thinks its totally worth it

That kit doesnt route back into the downpipe, which is what the OP wants.
