XJR6 Intercooler upgrade
#1
#2
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.

All of the above sound worthwhile - maximum HP/kW for minimal Pounds/$ is certainly appealing......

Thanks Cafopete.

I put the Bosch intercooler pump on, big difference, then upgraded to the Powerhouse 10% bigger supercharger drive pulley - also a big difference.

I have the standard system on my XJR6 and also have a spare heater circuit pump which looks bigger than the original intercooler pump. As I cant see much flow in the intercooler through the filler /vent plug, I am thinking of swapping this as a free upgrade /fix. Has anyone tried it?
Also the AC has been broken for years, so may take it of to save space / weight and thinking that I could replace the condenser with a second intercooler radiator from a breakers if I can find one, would a constant / manually switched fan be better?
I did consider trying to make a killer chiller type system as the look good. I saw a test on a Shelby mustang which added 50hp to a 500hp supercharged motor, so extrapolate to ~ 30hp on our motors, perhaps more with oversized pulleys. Not cheap though.

Steady on Xalty. I agree a very generalized and rough prediction, but from memory the 500hp factory Shelby Mustang used a positive displacement supercharger, with a water air intercooler not unlike like the x308 XJR but bigger. So a similar technology to our 300 plus hp X300 XJR6. On the Mustang. the article I read cited a ~ 50 hp gain on the dyno due to the near / sub zero degree C water temperature from the killer chiller cooling the intake air much more effectively than the say 60 - 70 degree C water normally circulated. I guessed that on our smaller set up we could expect a similar percentage gain, ie around 30 hp max benefit.
As stated in my original post this is just an extrapolation, and not based on any test data.
Where do you get your ~5hp estimate, from?
I am quite happy to stand corrected, especially on speculation, but please explain your reasoning rather than simply altering my words and saying 'Fixed'.

even if you keep the charge ice cold you’re still stuck with an eaton m90 and trying to gorilla overdrive it with an anemic AJ16 wont result in any gains.

That being said, cooler water will always be a benefit, as it is the final heatsink for cooling the intake air, and a lower temp will always result in greater heat transfer from the intake air. I have no idea how much difference a killer chiller would make in practice though and if it would be noticeable on the road.
I'm going to go the route of a bigger intercooler for my application and see what happens.
