Big claims here. 

Any links up on the website ?

So far, based on the maps.

Looks like 42 frame size 68mm & 72mm
And 45 frame size with 67mm and 73mm

Very interesting! I would be keen to hear more about the spool and flow differences.

I found these on their IG.

Id be super keen to understand more about the GXR42-68 and GXR45-67.. Especially how it compares to the EFR9180.. Obviously I understand the spool and response wont be the same, but be keen to see how much of a hit it will take!

Also, the 4 seem to have a max tip speed of 109k..unless I misread something???

The GX-R turbos are mostly more about classes than outright response vs power, which is why there are 64, 67/68 and 73mm versions.  They are an improvement over the existing inducer options at least flow wise but given they're G42 and G45 turbine options they will be a LOT laggier than the EFR9180.

109krpm isn't tip speed, thats rpm - the reason the rpm is lower than the likes of the 9180 is because the tips are further from the centre, meaning tip speed will probably be HIGHER than the EFR9180 at it's max suggested speed.

If I had something like your car and the things you sound like you're into I'd probably be most interested with the Xona Rotor XRE7169S, it'll have a response hit on the EFR9180 but you won't get a more responsive turbo than it that's capable of >1000hp.
