In simple terms we are T-Piecing into the cars AC system and the refrigerant is being split 50/50 between the cabin AC and our interchiller. Our interchiller is made up of 2 channels each consisting of 20 plates. In the first channel your intercooler fluid flows through, in the second your AC, which supercools your intercooler fluid extremely cold as low as minus -15c (5F). The cabin AC is not affected, if anything it is colder than stock since we add a touch more gas to the system. You then have a car which will make more power, and it will be consistent. You can hot lap it at the drags without waiting as it will be back to freezing cold by the time you drive back, and your engine is also protected from pre ignition since it’s running a colder intake charge.
We have completed a lot of R&D into our chiller design to get an even distribution of the AC gas across all of the plates in the chiller, this is essential to the cooling performance. What normally happens is the gas shoots into the chiller at a very high pressure and hits the base of the chiller, then some of the gas will revert backwards and only pass over the bottom few plates, this will not utilise the entire surface area of the chiller. So we have designed a specialised distribution device in the inlet of the chiller which forces the AC gas event across all of the plates. This results in the best heat transfer possible resulting in colder temps and getting colder temps faster.

HOSES AND FITTINGS
We refuse to use cheap and nasty AC fittings, they have built is issues along with long and short term problems. The hoses and fittings that we use are tested to SAE J2064 standards, and they actually exceed those standards. The burst pressure on them is 2500psi, this is impossible for your AC system to achieve, thus it will never burst.
As shown in the picture below, with regular crimp style hoses they are often plagued with the issue of trapping air and PAG oil in the crimp, which over time turns acidic
With the clamp system we use this never happens and you actually have a much stronger bite of the hose into the bite sections of the fittings, for a system that will last many years to come.
The fittings we use have a tensile strength on the weakest part (the radius) of 1600kg/3527lbs
The manufacturer we buy the hoses and fittings from warranties them as long as we use their hoses, clamps and fittings. As such we warranty the entire system, this shows how confident they are in their product that it will not fail and should it fail which is highly unlikely it will be replaced.
During SAE J2064 testing of the hose/fittings when it fails the part that fails is the actual hose bursting open at 2500psi ! The fittings and clamps remain intact still holding the hose to the fitting…only the hose is bursting open. This shows how strong the clamping system is and the bite force being applied to the hose/fitting. This is much stronger than regular crimping which is why the manufacturer is able to warranty their product.
Its a case of buying the best possible AC hose/fittings that is the most versatile, flexible to out needs and of a very high quality.
All of our fittings are custom made on our CNC to look and function with an OEM standard. They are pressure tested before being sent out, so they will not leak when installed correctly.
The results we have seen are amazing, the amount of HP being lost due to excessive heat is gained back and then some extra HP on top of that!
We recently tested our Interchiller in 36c (97F) summer temperatures
With the chiller only (competition mode) our IAT was at 10c (50F)
With the chiller and cabin AC running our IAT was at 15c (59F)
The cabin AC was unaffected and very nice and cold even on such a hot day. On colder days we have seen IAT temperatures range from minus -4c to 5c (24F to 41F)
A standard car without any Interchiller, the IAT is normally 10c above the ambient temperature, so when we are achieving an IAT of 10c (50F) on a 36c (97F) summer day this is equivalent to driving in winter time when the ambient temperature is 0c (32F) ice cold.

On a standard 2014 model HSV Gen- F GTS fitted with the standard 6.2L LSA Supercharged engine we saw a gain of 23.9rwkw 32.1rwhp. The gain in HP is possible because of 2 reasons.
The first being the air is colder the oxygen is denser and you are getting a better cleaner burn of your air/fuel mixture. The second reason is more interesting because your intake ait temps is lower, the cars ECU is not pulling out as much ignition timing as it would have if you were at a hotter temperature. On this particular dyno run we saw a gain of 6 degrees of ignition timing…that’s a lot of power made there. Remember this is on a stock car, when you make even more heat when you over spin the blower, the gain will be even higher as you remove much larger amounts of heat.
We warranty every component of the Interchiller system, we only use the highest quality components, which have all been pressure, tested far beyond the limitations of your AC system using SAE J2064 standards.
Our systems does not cut into the cars AC system or intercooler system in any way, so you can easily restore the car to stock and nobody would even know you had it installed.
