GT35R w/ Tial V-band Turbine housing .82/1.06 AR
I was curious if anyone has used the Tial V-band turbine housing on the GT35R. Or if anyone has and idea how it flows/spools compared to the T4 divided or undivided housings. Maybe someone form Aspec could chime in? Thanks!

It's tough to compare them to Cast by looking at them, since they are machined to have 1/3rd less material. Besides, I'm sure if they are stating 1.06 A/R, it's because they've done the internal measurements/design.

They are actually 1.03's not 1.06's, kinda funny because they initially were 1.02's , they are T3 volutes not T4 They flow slightly better than their cast equivalent T3 housing if all things a equal. Meaning a .82 TiAL will flow better than a .82 cast Garrett T3. We've done a few, for different framed turbo's and applications. Same goes for the 42R framed stuff it will flow slightly better than a T4 but it will not out flow the T6. Look at the housing it was meant to replace and that will tell you pretty much where your at.

I believe the T4 divided housings would flow better than the V band. Spool should also be better on a rotary with the divided T4.

I am kinda confused, at first I thought it was T3 < TiAl vband < T4 but then you talking about the 42R it sounds as Vband would out flow the T4? Or is that because the 42R should have a T6, like the 35R should have a T4 for rotary powered cars.
I guess flow and spool are main difference; any of them t3 or t4 frame or the vband should suit my power needs, as the most HP I would be looking for is 400. I like the fact of a vband, I have yet to have an issue with those sealing, and plus no need to purchase any replacement gaskets.
The picture you posted of the manifolds, what size turbo are they for? I particularly like the upper left (short runner) would this work with a GT35R Tial Vband? and does the turbo placement allow me to use the air pump?

I have the 1.03 Tial on a GT35R. I love it. It spools just as quick as my T4 did and might have a bit more power. After getting annoyed with T4 flanges warping from the hour long road race sessions, I went with the Tial. They flow exceptionally well and weigh less than 1/2 the cast iron T4's. Add to that, the ability to clock the turbo left/right and you have a real winner. I'd suggest them over a T4 any day.
