That's not true actually. The main limiting factor is the stock boost solenoid. I've run 25psi peak on the stock actuator and stock wastegate using an MBC with no problems. The only real power gaining effect of the EWG is that it vents a significant amount of exhaust with very little restriction. In essence it makes your TBE less restrictive because it now has to flow less gas than it did with the IWG.

The way I see it with an EWG your turbo will hold boost much higher and longer than the IWG can.
My boost drops to 15.5 lbs at 6500 but with a EWG I could hold it around 18 to 19 lbs at 6500rpm ......this equals mucho HP.......am I wrong?

My boost controller is set to 25 lbs but during a run I never reach more than 22 lbs boost cause the rpms are to high.

What boost controller were you running with the IWG. I've been able to hold about 17.5psi with the IWG with an MBC. The EWG allows the car to hold about 18psi with the same MBC, but there is no additional airflow at that point. I actually believe that a boost taper at that point would help keep heat down a bit, but I don't want to swap out the MBC for anything else at this point.

very nice... good time for sure.

Ive got the dual setting Turbo XS one. One setting for meth+pump and another for Meth+100oct.

was the stock wastegate ported on yours ...cause mine isn't maybe thats the difference

I'm new at this I verses E wastegate stuff, just trying to figure the differences. People can not be going with a EWG just for sound

Ed,

We both know how each other feels about this and that is cool. We disagree.

Now, with that said, your argument above doesn't make sense . Yes, the OEM turbo on the STI is a VF39. But, I'm talking about a stock OEM turbo (and you are too or else a ported VF39 would be considered stock but it is not). A stock OEM turbo means that it is not ported. It is not welded on. It doesn't have a bracket bolted to it in order to keep the wastegate shut. It doesn't have a 20G wheel installed. It doesn't have it's actuator replaced. It is 100% stock - unmodified - OEM, VF39.

At this time, there is no stock OEM turbo in the 11's. Simple as that.

Dang it, lol. You got way more mods than me, but not for long

How about if we take the bracket off the actuator arm and run it like that but still with the EWG? To be honest, the bracket is just on there for peace of mind. I'm confident that we'd get the same results without it even if the IWG blew open a bit.

There was no porting or anything else done to the internals of the turbo... hell, its only been out of the car for the EWG UP install .

haha actually ed
the turbo never even came out (not even close), i installed that uppipe without taking the turbo off,
i had my boost set at 18 psi and didnt have the braket on to help it closed and it still got 18psi

so if i take the braket off that hold the iwg shut and let it hold with the stock actualator, would you change your mind about my set up now? woflplayer

Your going for the EWG thing too??????

If everyone is doing it ....I may as well join you all to keep you honest...eh

We really need to set this straight once and for all cause I dont want to show up at a drag event this summer only to be going against others with EWG and I have IWG. My tuner pretty much garauntees me that 11's are possible with my car if I go that route.

will they let you run at the East Coast Shootout with a EWG stock turbo in the stock class??

I think your car 11onesti will be just as fast if you unlock the stock wastegate cause it will still let air out the EWG as well. Id be interested in the results when you do this.

[crystal_Imprezav]

No ewg for the moment, I got some other tricks up my sleeve and lots of self tuning. The benefits of the EWG is being able to free up the pressure at the turbine housing and also being able to hold more boost to redline. Considering you powerband for a drag event it always around 5000rpms or so and that is were the stock WG and spring start to drop off, that couple of extra pounds makes a world of difference.

jus for the record my car ran

12.2 at 112.5 on jus TBE, Pnp stock headers,MBC and tuned

very few mods
im sure i could have gone faster with those current mods
but decided to step up the game since everyone had way more mods than me
