Internal WG flow just fine and Soon I'll show what they can do with a built VQ35DE. Plenty of power.

over 20+psi of boost, yes that is likely the case. I've personally run the gt28rs at 18psi on internal wg without any issues at all. With a built engine these cars will produce 650+whp at those levels.

If you are shooting for over that with much more boost, then it might make sense, however I cant imagine many people are looking to go upwards of that, and yet so many run externals. They cost more, and as Ron has noticed, are a pain in the *** to install in our car if you want to recirc. Don't mean to derail, just my .02

I have no issue with IWGs and I think at lower boost levels they are a good, cost-effective alternative, but when you start to push a ton of air through them they can become an issue since insufficient flow = boost creep = boom. And like I said, I still believe you can get more precise boost control with an EWG as compared to an IWG.

Notwithstanding, on a factory NA engine that isn't built with lower CR, an EWG is probably total overkill. On my old STi I ran between 28-30 PSI on a GT30R and an IWG absolutely wouldn't cut it.

With the right preload and a good boost controller you can get some real good results out of the IWG. No dough EWG are better as the HP goals and boost demand increases. Here is a dyno graph of a car we just finished, it has our VQ37VHR stage one long block, Stage 2 turbo kit with internal waist gates running 16 psi, as you can see it does very well .

Nice! What was the CR on that car?

Nice number on this car good job

I cant wait to get my kit that's some good motivation right there.

Op congrat's on the completed project enjoy the car.
