The coolant resevoir would go somewhere in the engine compartment. We'll have to wait for pictures to know exactly where. Greg has said all along he isn't going to release pictures until the kit is ready. The coolant resevoir would connect to the water pump that comes with the kit, the water pump will have piping that connects it to the intake manifold, and also to the heat exchanger.
Distilled water is water that has been purified. In some cases drinking water is distilled water. But water such as natural spring water is not distilled. It just doesn't contain any impurities.
You would not have to drain your existing radiator. The anti-freeze and distilled water coming with the kit is for the heat exchanger and the water cooled manifold. Your existing cooling system will not be hooked into the cooling system for the supercharger.
ecu flash is the upgrade to the stock ECU to tune the system properly.
Fuel mileage should stay the same for normal driving. Under full power you'll probably get 15-20mpg. Most of these kits are setup so that if you are cruising at highway speed you are not putting that much boost and extra fuel into the engine.
The oil cooler would go in front of the stock radiator. Look at the placement of the oil cooler and differential cooler in the 357ti project car. It would mount very similiar to that. |
Some additional information I found by doing a search for "air to water intercooler" on google. There is a lot more information out there, just dig in and start researching.

There are two types of intercoolers: air-to-air and air-to-water. Air-to-air means that as the charge passes through the intercooler, the intercooler itself is cooled by air flowing through its fins. Picture your car's radiator but substitute the intake air where the coolant goes and you'll have a rough idea of how it works. In an air-to-water intercooler, the intercooler is cooled by a liquid rather than air; this liquid has its own radiator placed where it can receive airflow, hoses connect this radiator to the intercooler itself, and the liquid must be circulated throughout the entire system.
Each type of intercooler has its strength and weakness. Air-to-air units tend to require longer ducting to route the air from the turbo through the intercooler then back to the engine; this extra tubing might increase lag slightly on some engines and may also present interesting packaging challenges. Air-to-water units, however, can have significantly shorter intake plumbing; the intercooler can be placed in hot underhood areas where no airflow is present since the liquid coolant circulates to its radiator. This allows for simpler installation but at an expense of reduced cooling efficiency. Note that both kinds cool better when air is flowing through the intercooler (air-to-air) or the radiator (air-to-water); both kinds can benefit from the installation of a fan for low-speed operation.
Which type is better? Depends on your goal. From where I sit it seems that air-to-water intercoolers are used either for convenience--to eliminate the possible ducting nightmare of the intake--or for drag-only vehicles where a "one shot" setup uses ice to actually drop charge air temps below ambient... for a very short while. I think it is telling that a number of street cars which featured air-to-water intercoolers from the factory--such as the GMC Syclone and Typhoon--are almost always converted to air-to-air units when upping performance is the goal. Check out an issue of Turbo magazine; you'll see these cars with huge air-to-air units mounted below the front bumber (or else behind the grill and in front of the radiator). There's a message here somewhere.... |
