We will see. Garrett doesn't even offer those for gtx 30r and gtx 35r turbos. I think ATP does them.

 

From horsepower view, it seems that the G30-900 is similar with 6466, always referring in Garrett power output. The next smaller turbo that Garrett offers, is the G25 which has 660hp. I think the 6266 falls somewhere between those two turbos.

In my opinion the G30-900 will struggle to make 900whp like 6466 do. However i believe a G35-900 would be easier to achieve that or even make more power than a 6466. Also, i believe that those new turbos would be more responsive than pte equivalent units or gtx series, so it will be a win-win case if it meets our expectations and advertised power output

 

There is a g30-660 and g30-770.

 

correct, i totally forgot about these

 

Anyone see any results in single turbo application for the g30 900?

 

Also if the g30 770 is replacement for the gen2 gtx3071 does it spool any better?

 

I don't know about spool better, but it flows 10lbs/min more! Look to the G30-660 if you want better spool and equal power to the gtx3071r gen2. Of course, the G-series uses MarM for the turbine wheel which has a much higher temp limit than the inco wheel in the gtx = more power.

 

It's not really a "replacement". The Gseries is an entirely different turbocharger line than the GTX.

 

Was told the g30-660 is replacement for the 3067

 

Wheel size for wheel size, yes. They both have 60mm turbine and 67mm compressor. But both the turbine and compressor wheels are of different design. And the G-series turbo is basically all new too. Well, it came out 2.5 years ago.

Haven't quite understand what is its market segment since for every Gseries there is a gtx2 series that does the same

 

Size for size the g series out flows the gtx2, and the wheels are lighter, which means they spoil faster and have better response.

 

is there any link with back to back dyno test between the 2 series?

 

There's barely any gseries results. If you find one, post it here.

 

unfortunately i had no luck on my researches the last 3-4 months. On the other hand if it was as good as they say there would be results all over the place
