So my car is actually 2013 XJ 5.0 supercharged, But not a lot of xj guys mod And since it's the same engine I think it's related. I do have a tune so I am pushing 100+ horsepower more that's stock. Everything else however is stock . I'm seeing as high as 185f briefly after hard pulls And the track after some hard runs I was seing as high as 206 but it does drop down to around 160 after that. I did confirm that the pump is working but I'm not sure if it might be weaker than normal.
Just thought I would check if anybody actually monitor the temperatures after wide open throttle runs where they are at.

 

Intake temp would be related to coolant temp. When driven hard my coolant runs just over 200 so those temps seen reasonable to me.

 

Its a separate system with own pump and radiator. On my 08 xkr for example 140f is highest , that to me was reasonable temps

 

If it's a separate system how to you fill it?

 

It's exactly the same on the 08 xkr with sharing expension tank. I have an upper pulley and making more boost than the 5.0 2013 where temperatures are way higher

 

I think the 4.2 on your xkr has a better intercooler set up than the 5.0. I have an 06 str and see similar or lower like your xkr. I have read that a stock supercharger heats the air charge from 120f to 140f over ambient as it exits the charger. Spinning faster at max rpm would increase that heat. I have found that the intercooler system can remove 80 to 100f depending on outside temp and humidity. Ex. Ambient 100 + 120 heat created = 220. I see 130 as iat2 at intercoolers meaning 90 has been removed by the system. I would recommend upgrading to the bosch intercooler pump for sure. There is a coolant hose on my car that goes from the main water rail to the intercooler radiator that brings the engine system into the supercharger system. I would think the small hose from the charger rad to the pressure tank would be enough. I think your iats on the xjr are right. The upgraded pump will help. My mistake about the hose going to the water rail. It goes to a tee that goes to the bottom of the pressure tank and other side to the heater hose matrix. That is how the charger rad is filled i am sure

 

I Have ordered the Bosch 010 pump so will see how that goes on the 5.0. I do have a Bosch on my 4.2 but honestly I did not notice a difference over stock pump on the car.
Scott on a side note if you have a 06 str that car is easily tunable to similar power levels as my 4.2 Xkr especially with 06 year I should be able to do it easily over OBD2 . Let me know if I can help.

 

We have spoken about the tune before. Still making the cost work. Hopefully soon. I think your 5.0 has an m122 eaton. Correct. I do not think jaguar upgraded the cooler system very much. I have not seen one in person only photos. It is odd how the air charge coolers are set up vs the 4.2. It looks like the charger and coolers are integrated when i watched a how too video. Probably nothing

 

The 5.0 has the Eaton TVS R1900 not the M112.
This pdf explains the 5.0 SC coolant system: https://www.dropbox.com/s/8y4iax9hm2...%20V8.pdf?dl=0

 

thanks for the link. Informative reading. By looking at the charger/charge air cooler assembly i see why those can be a bear to remove. I think the tvs is supposed to create less heat then the m series. I wonder if the charge coolers are smaller in the cooling grid. It would also be interesting to compare cooler radiator size and capacity. I guess this is why most that have juiced up the 5.0 have also recommended an improved supercharger rad system

 

This document doesn't cover the supercharger cooling system, or have I missed it in there?

 

Just thought I would post an update with a video of what I'm doing or have just done. New pump is in, split the cooling system so far don't see any difference
