The bigger the turbo the bigger the gains will be by switching to an EWG, but it could be "worth it" on any turbo depending on what you consider to be "worth it".

38mm EWG on my 44lb/min turbo and wouldn't change a thing. 22 psi in third gear by 3200 rpms...with an aps dr525 fmic. Plus it hold that boost all the way through the powerband. That SOB kicks pretty hard if you ask me!

An EWG will not affect how fast the turbo will spool. It will affect 1. your ability to control boost 2. and it will allow you to make a bit more power because of the lack of WG recirc. 3. it makes your car sound like a fighter jet at full song.

Is it worth it to post here and be vague as crap? Do you drive a Kia Sephia? What are your goals?

1. Fill out your damned profile.
2. Try not to drop non sequiturs when you post, post cogent sentences with information so we can help.

Yea I was pretty sure EWG didn't effect spool, but never knew for sure. So thanks for clearing that up. I was trying to show that it holds that 22 psi from 3200 all the way up to about 7000. And the sound of EWG never gets old!

An EWG is a good idea on ANY turbo. The increase in VE is worth it.

What kind of gains could I see by running an EWG on a VF48? I'm planning on 750cc injectors, UEL Headers, and 1 step colder plugs along with a race gas (109) tune over my existing mods. I was thinking the EWG may complement those mods nicely, and maybe allow me to take better advantage of race gas

It laid down 316/360 on a dynojet with a VF48, Spearco TMIC, 4" Catless dp to 3" catback, walbaro, Samco inlet hose, GM BCS, 3" P&L intake, Cobb v2.

Sorry for the slight threadjack

The car has just about every supporting mod you could think of but it is on a notoriously high reading dynapack. Figure 365-375ish on a musting.

Not true. A good EWG setup can definitely aid spool. The EWG valve (with the help of a good boost controller) can be configured to hold completely shut until a desired boost level is reached and then pop open.

Sooo an EWG can help with spool up. Misinfo is no good and makes me feel silly for thinking something was right, then being told it's wrong, when I was right all along.

And to the OP, do it! It's worth it, I promise. The look on peoples faces when you pass them and it starts dumping when you're next to them is always great too. Like this

EWG recirc. isn't bad, but it's not optimal. FullRace tends to make products for people don't really care about noise.

You have a bad IWG if it cant hold shut.
