Garrett V-Band Twinscroll Housings at SEMA
1:20 in shows a 3D printed version of a twin scroll V-band inlet housing. Anybody have any info on which models of turbochargers are going to be available with these housings? When the housings may realistically be available?

Probably nothing that 99% of the people on here are interested in due to the close size to the stock IX turbo, but that GTX2867R has my interest.

The turbine housings will be available for the GT30R/GTX30R and GT35R/GTX30R turbochargers. Housings should be available some time in 2012. I will check to see if I can disclose additional details.

doesnt look like it will perform much different than the 3582 and the gtx3582 boot stomps it.

response is the key though.
We have twin scroll 3076's making 20psi by about 3600 RPM on a 2.2 litre engine. Max power is about 520whp.
If we can get the 3576 making 20psi by 3800, but making an additional 50whp, then that would be awesome.
I would really like to see some testing on this turbo and whether or not it actually works, or if it's just a marketing ploy
We all know how much of a dud the 3082 was...
compressor maps aren't everything

I beleive Garrett has actually produced a similar housing for the Ford powerstroke for a while now? GTP38R?
Cool to see it possibly coming out for the more mainstream applications though.
240Z, any idea what material it's going to be cast from?

As far as the material used, the nickel-heavy cast iron used in their standard housings may not be strong enough when cast so thin, and stainless may be the choice. Im not saying this will be the case, its just a technical info based opinion.

3082 (nee 3065) did this-

This was an 11:1/2.0L/aluminum rod motor with FP2s at the time. We switched to FP4s and made 640whp out of fuel.
Combo is everything. Even on the 9:1 motor the car made 580ish with the FP2s and ran 139mph traps at 2800 lbs.
With this "new" V-band twin scroll I am curious what the volute area is. If its choked more than a standard T3 or somewhere between that and a good T4.

Garret hasn't addressed this community at all when it has come to twinscroll housings. It will be very interesting to see how they do it. I agree, stainless is the only way to go due to the high EGTs and the benefit of being more compact (already a huge issue with Garrett GT25 to GT35 CHRAs).
Stainless would make sense for this market. If you go to stainless, I would think you'd spend the time to get good A/Rs as well. The GT turbine housings are pretty bad *** and excellent A/Rs are available for GT30 and GT35 CHRAs. I would hope the twinscroll housings would be no different.
Everything we base our opinions on with regards to twinscroll has been for very different applications. The 0.78 T3 for example was meant to go on something like a diesel tractor or generator. Something where HP was not at all a goal. The larger GT42 stuff was likely based around large frame diesels as well so the A/Rs are large, which works well still but the housings are very thick as they are made from cast iron as the EGTs of diesels don't require higher grade materials and the large frame CHRAs allow bulky housings.
The 1.06 A/R T3 is an ATP housing and the 1.0 A/R T4 while being Garrett likely still wasn't designed with gasoline in mind at all.
Either way, I figured it wasn’t going to be long until Garrett came out with a few “game changers” on their own to answer the EFR line. Between the billet wheels out (and more coming) and the improved housings, Garrett has some pretty nice things heading our way. Hope it pans out and doesn’t turn into 2 years of hype...
