Garrett's New GX-R Turbo Lineup and Overview

[@williamkillingsworth2619]

Suggestion, make the Comp and Turbine maps bigger as its hard to see anything and I have mine pulled up on a 50" screen. Like maybe put your face in the small screen PIP and the map full screen. Other than that good stuff and thank you for posting!

From my view, the g series compressors seemed to be catered towards ~3.0L or larger (piston) engines, where it takes less PR to get to the far right of the map. Dealing primarily with 2.0L 4g63, it seems like they will still land on GX race map when maxing out the compressor, particularly with shaft speed. And if I'm not mistaken, a rotary would generally require less PR than a similar displacement piston engine (rotary acting like ~2x its displacement?)

I was looking at the G45-1500 for my 20B, but was considering changing it out for a GXR45-73 based on similar power potential but less lag. What are your thoughts on that as an approach? Car has a sequential 6-speed gearbox with 5th now 1:1.

Most drag cars are spooled up by the time the green light is lit and are on methanol or E. So how fast it comes up isn't much of an issue. My thoughts on this is that it was becoming common knowledge that if you swap out a gtx or G series with a precision or Fis people were gaining power at these class limited builds were they are squeezing out as much as they can. Garret just wants a piece of the pie now with these new RACE wheels.

[@RGHTBrainDesignDrive]

@@fc3sluis They're using more lever arm with the larger radius to have torque on the air and slowing the shaft speeds. This results in more pressure being able to be requested. Here's the thing... The turbo won't make significantly more power whether it's at 50psi vs. 30psi unless it's overspun. What these may do for the GX-R45s is finally hit that sweet spot of that lazy turbine wheel.

[@V8Lenny]

They finally scrapped those restrictive full bladed wheels.

[@Drew-i8g]

Dont you need to add atmosphere (14.7) to the pressure ratio? Your calculations are at 0 psi?

[@RGHTBrainDesignDrive]

@@Drew-i8g PR1 = Atmosphere PR3 = 29psi, which is two atmospheres worth of pressure over ambient.

this 68 mm look vary simmilar too pte 6870 for same reason

Hey man thank you heaps for this video, great overview. Curious, based on the new wheels specs offered do you see any of these being a great street application? and if so, for what platforms? So you think these will be much more suited to applications where they have a narrow powerband?

[@RGHTBrainDesignDrive]

All of these are geared more towards narrower powerband, drag racing, class-spec rules and NONE of them are as good as the G-Series for street cars on pump gas or pump e85.
