Has anyone seriously explored removing the water intercooler system on the top of our 4.2 and replacing it with a bumper mounted system where it can breathe?

 

2003-2004 SVT Mustang Cobra Intercooler Upgrade - Ford Mustang Forum

 

That is a link to a kit sold for mustangs.. Seems to me the weak link in the stock eaton blower is the heat it produces. Can't think of a more effective way to lower intake temps than something like this.

 

The mustang link is not a Air to air intercooler. All they did is put the standard ford water to air inter cooler on its own circuit. The intercooler is still mounted in the V of the engine under the supercharger and has pipes to a front mount heat exchanger. We can segregate our intercooler system from the engine cooling system with much much less work.

IF you wanted to replace the intercooler system on your jag with a Air to Air intercooler you will have to do some serious piping. Every Extra bit of discharge lengh you add will Lower boost pressure. Stock you may have a boost pressure drop from the supercharger to the head of about .1 -.3 PSI. With an Air to Air and all associated plumbing you would loose 2-5 PSI easy. With a supercharger you Spend HP to produce Boost so you are paying HP to loose Boost and loose power. The majority of Roots or Twin screw intercoolers are Air to water for this reason. In real work dirving conditions i am not sure how much you would gain if any with Air to Air regardless of the complications and boost loss.


Some of the boost cooling people have done on this forum are:
Twin Screw
Water/Meth
Nos
Bigger intercooler radiator/pump
Extra fan
Chiller Killer
Isolate the Intercooler cooling circuit
Mist the intercooler radiator

 

Move to a TS like KB.

 

As I re read my post I can see why it was thought I was suggesting a air/air intercooler system. I was still wanting it to be a water intercooler. Just trying to have it run on its own circuit with more air flow to keep it cool. Hopefully this would reduce the under hood temps too and intake temps.

 

Does the factory system use a separate intercooler radiator?

 

Yes we do! Its actually a fairly large radiator. Much more surface area then the stuff listed in the mustang add. If its not a 80+ degree day and i dont get stuck in traffic i can pop my hood and the intercoolers are nice and cool to the touch.

What "R" car do you have?

 

2004 XJR.. If I understand correctly the engine coolant and intercooler coolant are the same system... Wouldn't this effectively heat the charge rather than cool it?

 

Test of signature

 

The engine radiator and Intercooler radiator are connected via their top hoses (radiator output). The top hose connection between the systems is not very large; big enough to help cool under high heat soak but, not saturate the system with heat. The ford add calmed coolant from the cylinder heads entered the charge cooler. This does not happen in our jaguars: only coolant exiting the radiator is mixed with the charge cooling system. The out put temperatures of our Eaton (heaton) supercharger in most cases can be hotter then the coolant running through the charge coolers. Eaton discharge temps over 250+ degrees are common (wot or + pullys). Our system is not perfect, but its far from bad. Jaguar designed the system to be stable and pragmatic.
