Water injection has many benefits, the main reason for its use is to cool the IAT [ intake air temperatures ] to achieve better performance. This is similar to how your truck runs better on a cool day, with turbo and supercharged engines that compress the air to force feed the engine for additional power, that compression creates heat and with added heat then power gains start to drop off. The key is to stop the power drop off by keeping things cool at near ideal operational coolant temperature of 180 degrees F.
One other way to reduce IATs is an intercooler, but the really nice thing about water injection as opposed to many intercooler kits is that you do not have an expensive part hanging in an area where it could be easily damaged. On the GM trucks often the only location chosen for the intercooler is where GM installs an optional thick metal plate or 'skid plate' to protect the truck from damage, as pictured below,
So you can see an intercooler in that location is NOT a good idea for many drivers. Water injection is a better option as it is easier to install and takes up much less room and has added benefits that intercoolers just do not have and no parts are in that area to get damaged. Intercooler tubing take up a lot of underhood room and can add labor costs when engine servicing is needed. To read more on why an intercooler is not the best choice click here.
The hi-pressure industrial grade pump and special nozzles assures proper spray pattern.
We have had NO need to install the 1997 Cooling Upgrades while using the water injection. We also found that the dual auxiliary cooling fans are no longer needed when using the water injection because everything stays nice and cool. Under some extreme conditions it may be beneficial though to have both auxiliary electric fans and the Water injection.
So as you can see from the above chart the site pushing products for GM diesels recommends a large bill of goods to reduce the cylinder temperatures and keep the 6.5TD running cooler, and then when your being sold on that stuff and need the engine work for the pistons you'll be advised to get splayed main caps and other nonsense you don't need and that can even be detrimental to the engine. All that nonsense is recommended by them when one simply needs to use a water-mist-injection system to keep the 6.5 running cooler.
