Oh yeah. Here is an image of the 5.0L TVS1900 with the snout off the front.
(In front, the snout has the coupler that mates it to the main body. The gear drives and area filled with oil is in the back of the supercharger.)
I've read that since the coupler isn't imersed in a bath of oil, they are failing and/or becoming noisy.
They are also having premature bearing failures in the snout.

Wow that must be a very recent change, the October 2013 parts catalog still shows the vacuum operated bypass valves.

I picked up one as a core with bad snout bearings a few weeks ago. Thought it would have the vacuum valve like my other one, but instead it was one with the electric valve. The case has "Jaguar Range Rover" cast into it above the part number. The casted P/N is: 350022 Rev A YJ1.

I hope we all realize that this has big implications for how Jaguar controls the engine. Rather than the bypass valve opening based on vacuum, there now has to be new control logic in the ECM that tells the bypass valve when and how much to open, probably based on a vacuum sensor. There is the same sensor in both the old and new snouts. I wonder if it is monitored by this sensor or somewhere else...

Joe I did a little more digging, the diagram for the blower on the 3.0 S/C engine shows the electronic bypass valve. The diagram from the 5.0 still shows the vacuum version.

Is the one you have definitely off a 5.0?

The supercharger I have is exactly the same form factor as the other 5.0 supercharger. Does the 3.0 supercharger use the same TVS 1.9 blower?

Could it be from a newer model 5.0 Range Rover?

I don't have access to the parts listing for the brand new RR's L494 or L405 with the 5.0 or 3.0 S/C engines so I can't check them.

But the old p/n for the LR supercharger LR011341 has been updated to a new p/n LR048089

I don't know if that's the difference between vacuum & electric bypass or not...

While looking I came across this guy selling "core" superchargers for $175 each, guess these are all the scrapped ones with bad couplers... Jaguar Range Rover Supercarger Core | eBay

EDIT

Actually it might be that the pictures don't get updated in the parts catalogue.

In the TSB posted here https://www.jaguarforums.com/forum/x...0/#post1172856 it shows that there are different parts used on the superchargers depending on if the car has the Denso ECU (prior to 2014) or the Bosch ECU (2014 onwards)

I wonder if the Denso ECU cars have the vacuum bypass, and the Bosch ECU cars have the electronic bypass...

The bypass valve actuator is made by SONCEBOZ, a Switzerland/USA company.
P/N is DX23-9C854-AA

http://www.sonceboz.com/medias/Marke...0Induction.pdf

No hits on the P/N on the internet. Perhaps if you do a "where used" on the part it might link back to what engines it is used on.

but its possible? I have ability to buy xfr supercharger quite cheap.

Huge task but almost anything's possible.

However, the usual answer for someone asking like this is: no.

Because you'd be taking on a task way beyond your likely comfort zone.

After resoldering 260 pints on 3 layer pcb (upgraded facelift cilimate control dash)I think I know hard work as I have never took out supercharged out and never comapred them directly i have no clue. if i need some metal custom parts CNC machined its fine. but if some critical locations is diferent it could be one way ticket. as my hope with "easy" upgrade on climate control. only supercharger is needed or other aprts from XFR?


I'm not expecting more gain with TVS bu i more expect cooler air, less stress.

I started by just getting the supercharger and try to make it fit, although I couldn't CNC nor Weld, that's what I had to learn.

So If you can weld/cnc , than its relatively easy.

But all this work for just cooler temps? That just doesn't make any sense, unless you enjoy the engineering of course, as its going to be a interesting road as you would need to do more than I did with the twin-screw because of the coolant piping in the way and possibly no custom length snouts, and this is assuming it will all fit under the hood.

For lower cooler temps you can be done in a day with a water/meth kit, and also way cheaper as well.

cutting not mached place and welding Allu not a problem at all( and I will not do this by myself) I/m more concerned about heights- will new TVS fit under the hood and belt drive issues. I can get mint condition complete charger for less than 400USD, labour 200-300USD.


now upon reading more I fount that TVS charger is less robust than M112(same for engine 5.0Sc vs 4.2SC) and this is makes me worry as well. going 150 000miles with original M112 charger oil with absolutelly no issues.


I just realized that nothing inside in my car left from SV8 (just light and washers stalks and original touchsreen) so why not go to engine(i really dont like hot temperatures of charger coolers) I do not desire for more power, would love to have more lower midrange grunt. drove 590HP XFR(pulley,reprogram, intake and exaust) and loved feeling of that very low RPM torque.

If you want the (tuned) 5.0 XFR grunt, then beter go for the 2300 TVS unit, just as much work as a TVS1900.

Why worry when you can buy so cheaply. Get a few spares.

because
1) its one time offer,other 5.0sc chargers is more expensive(800usd)
2) I dont like when my car broke down.its not matter of cost but matter of personal taste. I like robust cars. feeling better mentaly.

Before changing superchargers get the maps and understand what your current supercharger can do. The 650hp chev LT4 engine uses a TVS1740. Hennessy offers upgrades to 750 and 850hp. At these higher hp levels some supercharger efficiency would be lost by it’s doable.

Ah, looking down the rabbit hole and wants to jump. Oft times it's better to just look and leave things alone.

XF is smaller up front vs an XK if memory serves. I just don't see any of this ending well.
