Has anyone try to convert the air conditioner to cool down the IAT?
Usually you have to place a devolatilizier instead of the radiator of the compressor.
Or you use the radiator of the compressor as devolatilizier.

killerchiller.com. There should be a kit available for our cars in the near future.

+1 Killer Chiller

Been watching these guys for the last year waiting for a kit. This is the answer to our cooling issues I believe.

Here in germany there is a little company which integrated a devolatilizier in a compressor of a sl55 amg. Now the engine has 720 hp and 740 lbf of torque with this set up, bigger pulley, header, cams and ecu.

Do you have name of company or website?

Just searched google US and also Google.de and nothing shows up for devolatilizier.

Be interested to hear more.

lorie

By searching google you will not found anything.
At first I will talk to them before I will give more information.
The only what I can say is, that the guy worked in the past by AMG in the racing technology department, engineering design department for engines, aerodynamic department and chassis engineering department.
He concurred by designing the CLK-GTR til CLK-DTM.

Here you can see an E55 AMG from this guy at Hockenheim-Ring.

Look at 1:58 min at right rear wheel!

Although I am optimistic about such a thing, for cooling our IATS, even though I am a V-12 TT. I can only tell you that the engineer in me says it can not work.

Meaning NO free lunch here guys.

By definition of man made products, aka NOTHING is 100% efficient.

The energy to compress the gas, refrigerant, will exceed the pay backs from the IAT decrease.

Keep in mind that all of the process, aka cooling the refrigerant, 70-80% efficient at best. Our inter coolers, even less due to surface area.

Oh well, I don't mean to kill anyone's fun, but I am very apprehensive at best.

Good luck

Sorry guys but there is NO such thing as a perpetual motion machine, at least with our current technology

i always wondered if a double walled intake or intake tubes that are freeon cooled would work . Any inventors out there ????

Here is the next chance to make GAZILLIONS .

Didn't Black Sabbath have an album out called Devolatilizier?

I see your point, but the killer chiller is proven. I also own a Ford Lightning and they have seen nothing but great results from the KC. Lower IAT's = more power. It's not robbing power at WOT because the A/C compressor is disengaged. Its the cooling effect during idle/cruise that keeps the IAT's cooler before/during WOT.

EDIT: Here's a video from one of the owners. He is not sponsored by KC.

These were his times at the track. Posted on Lightningrodder.com

Oh.. i also forgot to mention that some of the guys are actually removing their heat exchangers to increase the cooling.
For those wondering why, the killer chiller is reducing coolant temps to BELOW ambient. This means that when air goes past the heat exchanger, the air is actually warming up the coolant causing a reverse effect. Removing it made the killer chiller more efficient. However, you must always be cautious of your coolant temps if for some reason the KC was to fail (however, I have yet to hear of one failing as of yet).

The Idea is to cool a sealed system wile your driving or sitting and that the AC will turn off when you go into boost or wot. Basically like running Ice in a rear reservoir all the time with out the need use ice.

Jakpro1

If you are gonna go chiller than you HAVE to go larger res tank somewhere. KC will tell you that straight up.

You run the chiller into the res tank for a large tank of ice cold coolant, then pump it straight into the intercooler....then out into exchanger for a bit of cooling then back through the chiller.

guysandiego

how much is this setup running other cars? can we get a ballpark for this mod?

Tech-Tune

Wow... below ambient, thats amazing! It makes a lot of sence to eliminate the heat exchanger. Think of the weight savings.

I'm surprized I havent read of anyone trying this on their E55.

chiromikey

why eliminate the h/e? just run the lines properly (like we do with out trunk reservoirs), ie; from the i/c to the h/e then to the killerchiller and back to the i/c. that should make for even more efficient cooling.

as long as there's a bypass switch so i can have full a/c during the az summer months, i'd be willing to try this. otherwise you can keep it!!!

Yacht Master

I concur, the laws of thermodynamics have not been repealed, you still have to remove the heat from the condenser.

I have been building compressor based supercooling for computer systems where we cool down a 300W load to -100c with multiple compressors and various refrigerants.
-30c is possible for about 500w.
For cars phase change cooling is feasible , especially when we would be willing to give up The AC.

For people with trunk reservoirs setting up subambient cooling capabilities would actually be relatively easy

guysandiego

i cant give up the A/C -- i need it -- Mercedes without AC thats got to be against some kind of law.

lightningfast7

You get to keep the AC in the cab.. in cab cooling is slightly affected after some "spirited" driving.. but from what the Lightning guys have said, it's not enough to keep them from the extra horsepower.

lightningfast7

I supposed if the coolant temps were higher than ambient going into the heat exchanger that would make sense, but the minute the coolant is below ambient "pre-heat exchanger", you're wasting the efficiency of the system.

chiromikey

under normal use i can't see coolant temps remaining below ambient after running through the i/c core...but since our s/c's are on a clutch drive and can essentially be "turned off" under very light loads i think it could be possible if one really tried.

i still don't think i'd give up my h/e or any a/c efficiency for this mod...

bassn_07

I have seen first hand at what a system like this can do. I personally watched his IAT's go from 85 degrees down to 55 while in the staging lanes. His system by far outperformed my reservoir at a crowded TNT day. His IAT's stayed around 50-60 while mine went to 80-90 (started with ice but long staging times kill that) while waiting 15-20 minutes in the lane...

Hopefully he will post up once he's ready, but I assure you it is working and fully operational.

BTW...he has no reservoir, upgraded HE, and his system is not even split..... This will be going on my car once he dials in everything and I'll update you guys.
