Default XJR6 Intercooler upgrade

Hi all,
Has anyone here successfully upgraded their intercooler radiator and or pump?
All ideas welcomed - my S/C coolant temp is around 80C, with the standard set up and proprietor of dyno shop believes he could find another 50 odd RWHP.
Cheers,
Bonn

There are quite a few threads here, and especially in the X308/X100 sub-forums about upgrading the circulator(pump) and intercooler radiator.

The three components that are often discussed are:

1) Jaguar XJR Intercooler Radiator Upgrade, Eurotoys,Ltd.

2) Bosch 0 392 022 010 intercooler pump/circulator upgrade: https://www.jaguarforums.com/forum/x...t-pump-199158/

3) Add an additional pusher electric fan in front of the intercooler radiator to reduce stationary or low speed heat soak.



The general consensus seems to be that the pump upgrade is beneficial, but the Eurotoys radiator may be too thick for proper cooling in street use. The additional cooling fan... not sure, but it can't hurt. As always YMMV

Another good option is Killer Chiller, which is what cars like the Dodge Demon and Hellcat utilize.

And another potential option I've considered is to utilize the X308 intercooler radiator in place of the X300 radiator if the X308 radiator is a higher capacity while retaining the same OE thickness (see Eurotoys radiator comment above). I haven't measured the X300 radiator yet to see if the X308 is larger, but the dimensions of the X308 are:

560 mm wide (excluding the mounting ears and hose ports), 310 mm tall (~320 mm measured along the side flanges). The core is 32 mm thick and the thickness measured at the side flanges is 50 mm.

I've also toyed with using the oil cooler that is present on European XJRs and the XJ12 as a secondary intercooler radiator. I have the oil cooler from a wrecked XJ12, but haven't fitted it yet.

Thanks for that info, Al - much appreciated. Will do some measurements, etc - mine's in an XJS, with the original AJ16S Intercooler radiator. Also have a spare BMW Siemens E39 Pusher fan, which is fairly slimline - albeit variable speed, but should be easy enough to re-wire for 100%fan speed.
All of the above sound worthwhile - maximum HP/kW for minimal Pounds/$ is certainly appealing......
