Twin Scroll Turbo system?
#77
OK, round two.
What about this? running all gases in one hole at low RPM, to get velocity up early, then open for the other as RPM increase. And yes, we would need at WG on top of this.
I'm thinking its so simple, that someone MUST have thought of this before. When WG can take the exhaust heat, it should be possible to have a valve here that can work as well - or?

Mazda have done it: TurboRX7.com > Rotary Engine History, 2/3 down, Twin-Scroll Turbo.
Then I'm at least not stupid - only a bit slow
I guess the biggest problem would be fitting it to a low mount? And maybe getting a turbo replacement for that fits AND have twin scroll.
Fazda, do you have a twin scroll turbo? Or do you just increase exhaust velocity? Any dynos?

Has anyone watched this: The 3D Printed Variable Turbo - /INSIDE KOENIGSEGG - YouTube ?

My system has always been a twin scroll, T4 just different sizes, started with a 1.0 then .84, now .84 with quickspool valve.
no dyno yet, but I have old logs and new logs

Let's wake this up again,
Fazda, could you make something like my extreme high tech dwg's of your setup? Hot side....

Acura rdx turbo is way cheaper - also related to the mitsu ihi series which makes me wonder what the upgrade possiblities are .... you can prob nake a low mount if you are willong to sacrifice some passenger leg room

Dunno how practical low mount would be. QS is best fitted to larger turbos, not smaller ones. One of the big issues with big turbos is melting the exhaust ports. Top mount reduces heat build-up in the ports, allowing for more power with (slightly) fewer heat issues in and around the block. QS in a top mount setup like Fazdas sounds near ideal.
