So who's going to try this thing out?

http://www.turbobygarrett.com/turbob...gers/gtx3584rs

New 9 blade turbine wheel
90lb/min on a 67/84mm wheel

Also reverse rotation GTX30/GTX35 turbos out...

Reverse rotation looks dope. Wonder how the spool sounds.

Hell, the new 3076 supposedly is a 750hp turbo lol

Yeah, their hp/lb of airflow is pretty optimistic. ~11hp/lb is doable on E85 and similar oxygenated race fuels but 9-10HP is probably more realistic for the typical setup. Still lands the GTX3584RS in the 850+ range.

The turbine map seems the same for the GTX3584RS though as the regular GT3582R so I'm guessing it's bad data on their site since they are claiming it's a new turbine wheel.

The turbine is a new aero that has been in the works for more than 2 years. It is supposed to spool the same, but flow more.

Side by side of the compressor maps for GTX3076R versus GTX3076R Gen 2

On a MOTOIQ video, it looks like the GTX3584RS turbine is likely sitting around 30lb/min on the middle A/R housing which puts it right up with the 1.06A/R GT35 wheel. Similar flow but with a smaller A/R should make for some spool improvements, although the aero load is very different between the different compressor wheels.

It actually doesn't look like the GTX3076R Gen II picks up airflow where we'd actually want it???

It does look like it could spin much higher then what it's mapped out too, likely getting very close to breaking into the 70lb/min range where the GEN I is DONE around 65lb/min.

In general, it looks like the GEN II stuff is targeted towards higher shaft speeds, which really should match up well with their smaller diameter turbines. WAY less likely too surge too on the GEN II stuff as well.

Here is a link to the product sheet off the ATP Turbo website:
http://www.atpturbo.com/info/Garrett...84RS_Specs.pdf

The turbine flows almost 35lbs/min in the big 1.21 A/R. I like the fact the new turbine hsg is stainless steel. On race gas, it should max out around 900whp. So it's a comfy 1000hp crank turbo.

So does this mean the new Gen 2 3076 is a better option than an FP Red?

Well, firstly, I'd personally only do the 3576 to reduce back pressure. Secondly, I haven't kept up with what FP is doing and they don't show any compressor or turbine maps, so it's hard to compare.

Well, the HTZ Red is rated as a 61#/min turbo.

THat's all I got though. No FP compressor maps lol

Only Robert has those

Looking at the new GTX3071R GEN 2, the new 71mm compressor wheel does 60lbs/min at 140k rpm speed line. The interesting thing is... that wheel should be able to go to 150k rpms which I'm guessing will put it at 62lbs/min. They even mapped the 76mm wheel to 145k and the 71mm can spin higher.

Are the 3071 and 3076 T3 turbos? And maybe a dumb question, but can you get those in twin scroll housings?

spdracerut

iTrader: (2)

Yup, can use all the T3/T4/v-band housings in standard rotation designed for the previous GT and GTX series as they all use the same UHP turbine wheel. Only the new GTX3584RS has unique turbine housings to go with the new/different design of turbine wheel. Garrett also has the T3 and v-band twin-scroll housings for all the GT/GTX turbos.
