Is 800$ you doing the work or did you have someone do it? I am not to familiar with the X and it's systems, did the blower have to come off or is it piped thru the stock cores? I would have no problem paying 800 for a killer chiller. They were four times that last time I saw but of course that was years ago.

 

I have isolated my cooling system by adding a seperate resevoir & a second pump as well as a resevoir tank mounted next to the Killer Chiller. I also run the system in reverse with the factory pump going binto the r/s charge cooler then into the left side then out ( this was done after seeing how Rocketsports plumbed there car on the XFR they setup to go over 200 mph & conversations with Tony ) then to the second pump which then goes to the tank & over to the Chiller then to the factory pump. The supercharger fitted to my car is one of Andre's Twin Screw setups with a 3'5" custom air meter & intake setup.

 

Thats what they run. You would just have to modify the fittings to run in a STR. You dont have to touch the intercoolers just the piping. Here is their layout of how its mounted. KC is obviously the killer chiller cooler.

 

I installed the kit myself, it was time consuming but what isn't on our cars. The only thing I can suggest is you be paitent as nothing ever just bolts on, but in the end it is worth the efforts.

 

I have no problem doing the work. If it works with the stock cores and is just a bolt on (no matter how hard) that's an awsome cure to heat soak. Thanks for the info. The cryo kit is 500ish so I have no problem going 800.

Btw forgive the horrid post I am on the cell.

 

The nice thing about the chiller is once it is installed just leave the climate control on & you have nothing to worry about refilling. I love the way it works.

 

I am guessing you just get the cheapest kit KC makes since they make none for the Jag. And your saying in your setup you seperated the stock cooling system. Added a new res and pump and then used the stock pump also? I can't picture it without a diagram. I understand the diagram Vance posted.

I am very interested in this. I may do this mod right after the intake elbow to get it nice and cool prior to the pulley swap.

I appreciate your breaking it down for us.

After reading it a third time I may have it. One pump to run through the fac core and another to run through the KC core to make up for the pressure drop of adding the second core to the system? Why the second resv at the chiller unit?

 

The resevoir between the charge coolers & the chiller is to increase the volume in the cooling system.

 

qwikcat, ICS uses a Dynojet 424X dynomometer. It was 83 degrees on Dyno day (it was 50 degrees the day prior). I forgot what the humidity was, it was a slightly humid day though. The second pull was 360 rwhp, the third less. She felt somewhat strong on the 45 mile highway drive to the dyno, then slightly slugggish around the town driving trying to find the dyno shop. She's a beast on any day below 80 degrees, especially cool days. Because I needed to return to the office an hour after arriving, there was little time to cool her down. The tech put a bag of ice on each charge cooler and sprayed water on intercooler barely ten minutes before each run. I paid for six pulls but had enough time for three. The tech felt another 20+ hp (380+ rwhp) was hidden behind the heatsoak. Tomorrow I'm going to perform a hard re-set of the ECU because I feel the ECU learned some de-tuned habits. Sounds like the "Chiller" is the way to go? I'll let yas know what's up with Paramount Performance. They consistently yank 450 hp from 4.0 s/c and 495 to 508 chp from s/c 4.2 XKR's. One of their STR customers has a YouTube vid with 475 chp (420 rwhp) via hi=flow cats, Millitek exhaust, 3 lb. pulley, and ECU tune.

 

Got you, makes sense. I am excited about the KC. One of the best post I have read. Now if we work the ecu out we can ring some power out of these things. I will be in contact with kc tomorrow to decide what unit I need!

Thanks

 

Thanks for the info. That heat soak is a killer. I bet in cool weather it would go better then 380 unless it's just making a ton of heat with the added boost? The ecu could be key along with added cooling if it's pulling timing or just so pig fat rich.

I have seen race cars lose huge power when the NOS runs out and sprays just fuel so the AF goes from 12 to 10. It's shocking how much it kills the power.

I will try the KC and we will see how it looks on the dyno but I expect that or the C02 spray would make 25-35rwhp alone maybe more on a summer day. A car with added boost could only like it more That Paramount number is about what I would expect in the right weather. Never heard back from euro toys but I am going to keep on them. I will try it latter if they have the answers I want to hear.

 

Er, they're already in effect separate. They just happen to share a common expansion tank.

I'm sure there's SOME mixing, but in terms of important heat mixing? I doubt it. Anyone measured?

 

Yea I had heard that but what concerns me if I'm chilling my intercooler side to the point of making the intercoolers that cold I'm worrying about that cooling off the engine part too much. Having the coolant on that side making the intercoolers fog then hitting the engine coolant at 200 degrees I just see bad things happening, in my head I'm thinking this, it may mix fine. But even when you put ice into water at room temp it cracks. That why how much is heat mixed would be good info. I think Mafioso knows the amount but I dont remember what he had told me.

 

OK, I get you and you could well be right. They are now effectively almost separate but you may well want them actually separate. Have fun with two low coolant sensors and yet more hoses LOL

 

Another advantage to have them isolated is with the second resevoir you are able to further increase the capacity of the system. I also seem to remember that the XK-180 had a seperate cooling system for the supercharger as well.

 

I'm all in favour

Just hoped to avoid the various hassles.

 

Here is a thought maybe have a guage for temps of the intercooler circuit and wire a light to that for low coolant in that circuit so you can know if you have trouble and which circuit its in. I think I may be on to something now just got to get the money for parts.

 

qwikcat, what's your take on your supercharger port and polish? Any noticeable differece? Did this decrease intake temperatures?

 

????? I don't have a SC port/polish. I do have it on the list of things to be done. I am going to send it to Al Billes supercharger god from pro mod drag racing if he has time to look at it, if anyone can make power out of the stock unit its Al. His worked pro mod kobelco 14-71 and 16-71 blowers are things of legend, you cant even buy them you just rent them and his time. He just makes that much more power then anyone else. I think he will at least be able to tell me yea we can wring some more power out of this thing or dude your wasting your time since that's as good as it will get.
