I have read and read, searched and searched, even called people and cannot find anything but conflicting information on this. I hope that someone who works at Jaguar on here can find out the truth and let me know. What type of Supercharger is on a XFR/XFRS? I have read numerous sites saying it is a M112, and a ton of them claiming it is similar to the one on the ZR1 which is a TVS MP2300.

On this Jaguar parts site it actually says it is a eaton m2300 TVS blower. Here:

2009-15 Jaguar XF, Range Rover Supercharger 9W83-6F066-FA

They say in the first linked article the 5.0L blower is different than the 4.2L and all the other blowers Jag has used. So does that mean the 4.2L is the M112 and the "more efficient" XFR blower is the m2300 TVS? It makes sense in my head but I can't find a definitive answer. On the second link it says it is a m2300 TVS and it still specifies a M112 3rd generation blower. That makes no sense whatsoever.

So I go to Eaton's website and get more conflicting info. They have 6th gen three vane 60d TVS2 blowers optimized for low end and the four vane 160d for higher rpm applications. According to them they make Three vane TVS2 blowers in 6th gen. Is that what we have? Is that still considered a M112?

Basically I want to know Type, Generation, Configuration, Liter size, CFM, Eaton specified limits of the XFR/XFRS blowers. Does anyone on here know for sure and not speculating out of you know where? If it is a M112, What gen? Specs with compressor map? Is there anywhere I can find reliable info on this thing? Finding people who know about this blower is like trying to find bigfoot.

 

It's TVS1900 like all 5.0 AJ133 supercharged engines.

Thank you sir! You are a scholar and a gentlemen. This is good news... I wonder why that thread didn't show up in my searches...
