Ah, I see.
So... it's like you, the Shodan, are an *** but not all asses are you! Got it.
Get off your high horse for ALL practical purposes on this or ANY other automotive enthususiast site they ARE the same. Sure... wanna find an exception have at it but look at the big picture or head back to the college lecture hall where you can correct everyone and feel superior.
Your follow up corrective grand standing post will just certify the point. (wink)

I'm sorry I don't have a cross-section of the two to show to give better imagery, but here's the differences in inlets themselves.
Here's the smaller twin scroll Mitsubishi inlet

that's the exterior nozzle that you're looking at, not the interior volute overall size within. That's like saying a divided .78A/R or T4 .68 housing has two A/Rs. That measurement doesn't measure the actual volute "channel" inside
9.8cm^2 and 10cm^2 is like a .68A/R and .73A/Rs in T3 "language" respectively.

Re: At what point is a twin scroll setup needed?
Ive heard of turbos using a variable inlet guide vanes, does anyone have any info on this?? Im in the aviation community and i know our jet engines use variable inlet guide vanes to change the direction of air hitting the fan blades for maximum air efficiency. I had heard they either had a turbo running this kind of setup or was in the making so you could run a larger turbo but have faster spool rates for lower end response. Im sure something like this would be quite expensive and as well need a control unit but using some of the technology that fighter jet motors use would def be cool and give you a awesome response rate across the rpm range. Im just wondering if anyone else has heard of this and can confirm or deny these types of turbos.

Rather than reading what he has to say and learning from it, you can retain your position of ignorance. The Shodan has helped me (and others) countless times over the last few years...he has a vast wealth of info to share with us, but when comments like this are made, its no wonder that HT is starting to devolve into a forum full of half-wit teenagers.
For future reference, if you plan to make a follow-up post to this, save your breath because the "Delete Thread" button has your name on it...and thats a promise
