Have finally chased down the core used in the ****** chiller

This is a 20 plate 44 kw heat exchanger and around $75

Installing it under the hood in place of the carbon filter then having a custom made tank fabricated . I have made a wooden template to see where the best place is to fit it

On rhd cars it's right next to the aircon pipes .
The heat exchanger should be here on Tuesday , another view on fitting location

Next job is mocking up design for the tank .

Just got to decide on how to connect the pipe work , do you guys think installing the chiller to cool the tank i(piped into the return ) or piped into the flow ( before the supercharger inter cooler ) ?

Best to go straight from chiller to IC, I feel. I also don't think there really is a benefit to a small bay mounted extra tank when running the chiller. I haven't seen the need with my chiller. Now if you were setting up for drag then maybe a large trunk tank that the chiller can dump it to but even then going from trunk to IC seems like temps will increase to me. You should wrap the cold side of the lines to help keep heat out, I haven't done this yet
myself. I do wonder if maybe you could run 2 chillers in series to super cool it down esp since you found the core for cheap. Which you will also likely want to insulate.

Have you guys consider the laminova core?

Me and Blackbenzz were talking about the laminova cores (his kleemann s/c had them) and were trying to see how we could make them work on the 55K. I found some cores not to long ago and was thinking about buying them just to see what i could fab up.

The guy in Germany I orderd mine from also dose 20 plate and 40 plate heat exchanger ranging from 22-70 kw of cooling .
I still like the idea of a small under hood tank , to hold 6 ltr of water to hold in reserve . I'm going to be using a Johnson pump running continually and the power to the original pump to put the front intercooler on through a diverting valve . The idea being to have a reserve of cold water for wot and the front inter cooler coming on line on boost .

I think the laminova core would be ideal for the killer chiller.

You need a tank in order for the KC or chiller to work. Once you go WOT, the compressor turns off and the lines will not be cooling the supercharger coolant / water. The benefit of a nice 3 - 5 gallon tank is you can cool plenty of water for a drag race or spirited canyon runs.

Since I actually have one installed and put the spot light back on using a KC I haven't seen a time when I needed more fluid. To clarify I am running the BMW reservoir from when the IC system was split. I don't have a large tank at all. I can't wait for next week to see how it does with the new 195 pulley and other goodies!!!

http://tinyurl.com/8klgegq a good read on using a chiller


But I am glad others are trying it out in varying configurations and glad we found a cheaper core. I love my mounting location as well!!! See page 10 post #149 in link above.

I know you have one and did a great DIY....I am merely making sure folks understand how the KC works....According to KC and basic thermodynamics, the more cold fluid you have the better. Obviously if you had a 100 gallon tank in the trunk that would be stupid as it would take forever to cool down to 50 degrees and would weigh 1000 lbs. From what I have read, it sounds like anything bigger than 2 gallons and smaller than 5 gallons is fine.

If all you have is a BMW reservoir, post your logs and then we can compare with other cars running similar boost and larger tanks. I only have a 175mm pulley, so I won't be a good comparison.

Kudos for coming up with your own chiller.

black06c230

no problem. When I get it back it will have a 195, 82 TB, MBH LTH, and other goodies. I will certainly update with result.

still I bet for most the KC is the best method to keep things cool as a track time or 2 is nothing. Daily street driving it is what most seem to do around here. For that it is by far better than a larger HE and tank combo.

Nearly got the pattern made for the under bonnet tank , not done the Maths yet but I think it's about 3 gallons . Rather than alloy making it out of carbon fibre with a little bit of help from a friend . Pics to follow soon

Nice find. Did you decide on that size based on available room or did you do the energy calcs since it looks about 1/2 the size of the KC kit option.

Hi , the first one I looked at was a 20 Plate heat exchanger and was rated at 44 ke in the end I decided to go for the 30 Plate rated at 66 kw . In the end after reading the advise of members on this forum decided to fit the chiller in the front bumper rather than under the hood . Main reason was to allow more room for the coolant tank .

black06c230

good choice as that is by far the best place to put it

black06c230

any update on you progress?

marc.l

So far ......
Buck or plug made for the carbon fibre tank , now making the mould .
Orderd hoses to connect the chiller for to the exspanshion block that connect to the air con pipes
Pipe orderd to pipe up the inter cooler

Will do some photo updates next week !

Many don't like clicking outside links. But from reading it seems to be going well, best of luck.

Here you go. Android tablet to the rescue. Not sure why IOS is giving you issues. [IMG] link [/IMG] Works on my iPhone even.

Thanks
Have tried every thing , but I'm hosting the pics on sky path this may be the problem ?

The tank plug ready for finishing ,

I must be stupid , was linking them to my skypath rather than to image shack !!!! Sorry about that !
