Looks like a TVS2300 is now available for the AJ133S 5.0 Supercharged engines.

Posting this all over the forum for exposure.

 

Wow! Thanks that's a nice find! Can't say I can swing it but going to 2300 from 1900 in the same size package is amazing.
$6200 is not bad and it fits as if stock. Crap! That's Oz dollars. When I changed it to USD it's only $4150!! Now I am really interested!
I was planning to replace my clunking snout and get the blower and snout ported for an estimated cost of $1200-$1500. This would be so much better for not a lot more money.

Surprisingly they supply a solid coupler.
Here is their reason;

"upgraded solid coupler eliminating the factory OEM spring coupler which is prone to fatigue and failure"

Only for cars with the electric bypass. Since that's in the snout and you can remove the snout. You should be able to bolt on the older style vacuum bypass snout?
Don't know if that would work?

Lucky I have the electric version on my 2014.
