Default Any measurable advantage to running EWG w/ stock turbo?

Title says it. I can't imagine that there is, but I'm sure people have some real world thoughts.

With EBC a little faster response and no danger of over-boost with other mods.

Not enough to really justify it though . . .

IMHO, to justify its' price, the S209 needs to perform at least as well as my moderately powered 05 built beater, and even that might not convince me to buy one cause my next STI isn't likely to be moderately powered.

It really depends on what your goals are and the setup you're using.

EWGs do reduce post turbo backpressure, as well as reduce exhaust gas flow turbulence; the primary benefit being on the exit side.

If you want to eek as much performance out of the stock turbo setup, EWGs will definitely be a mod worth considering, as it will most definitely make more measurable power. Of course how much is going to be based on several factors.

From a safety standpoint, EWGs should eliminate any possibility of boost creep and open up more safety headroom from a WG duty cycle standpoint.

The sound differences are significant. This is what pushes many away from going EWG. They are extremely loud when you're (generally) above or near WG spring pressure. Below this point the car will be about as loud as non-EWG. For me and how I run our setups, that generally means I can run up to ~12-14psi of boost before any additional EWG sound comes alive. So for 'normal' and even light spirited driving the car still scoots pretty well. Boost levels higher than that it will start to whistle and then as boost builds further (full spool) it will roar.

Our turbo is known to boost creep once you start flowing more through it mainly due to the wastegate size and design. An EWG would prevent that but I'm not sure the benefits would be worth the cost. You could use that money towards an upgraded turbo with a better IWG. If you are looking for sound that's more subjective.

Default Re: Any measurable advantage to running EWG w/ stock turbo?

I like the benefits of an EWG, but the noise alone is why I would never run one again. Even my race car uses an IWG as I don't want to listen to it for 20 minutes at a time.

It depends on what you're hoping to accomplish. Eliminate boost creep or make more power?

I wouldn't go for an EWG for the noise alone.

If you want to keep the stock turbo, I vote for having the turbine housing and wastegate entrance ported.. a little more power, reduce the chances of boost creep, and keep the noise manageable.

As KillerB explained, the EWG will make more power if you're okay with the noise and the added cost/complexity. I'd vote for upgrading the turbo at that point though.

You could say the same thing about most ratted out bugeye owners. So are they too loud or am I too old

Default Re: Any measurable advantage to running EWG w/ stock turbo?

Im on stock turbo and have been using EWG for years. Boost creep is inevitable here in the colder months of the northeast and EWG serves its purpose of boost control. I will say that when i went from IWG -> EWG the car grealty changed the way it boosted. So much more repsonive and precise, almost like it was immediate.

Yes EWG with open dump is LOUD. So loud that you wont here your exhaust (or anything else) when its open. I will say that it does sounds pretty badass but it can also be annoying at times. It will pretty much force you to behave unless you want to be noticed lol. I think of it as a great excuse to stay out of boost. Either way, you will have to change your driving habbits when running EWG.
