00:00:00,000 --> 00:00:08,875
As part of a two-stage manifold air-cooling process, the water-based intercooler (WBIC) provides the first stage of cooling.

2
00:00:08,875 --> 00:00:13,375
The WBIC cools the air discharged from the turbocharger.

3
00:00:13,375 --> 00:00:21,167
At Notch 8 engine speed, the outlet air temperature from the WBIC is typically around 200°F.

4
00:00:21,167 --> 00:00:27,792
Factors such as engine load, altitude, and ambient air temperature can significantly affect this value.

5
00:00:27,792 --> 00:00:31,667
The WBIC is made up of a core and an outer shell.

6
00:00:31,667 --> 00:00:35,167
The core is a mechanically bonded tube-and-fin design.

7
00:00:35,167 --> 00:00:40,792
The cooling water flows inside the tubes and makes two passes through the shell before exiting.

8
00:00:40,792 --> 00:00:45,625
The turbocharger discharge air flows over the tubes and fins in one pass.

9
00:00:45,625 --> 00:00:53,250
The outer shell, which may be either fabricated or cast, provides the rigid frame for mounting the intercooler core.

10
00:00:53,250 --> 00:01:02,417
To distinguish between the two designs, which are referred to as the fabricated WBIC and the cast WBIC, consider the following:

11
00:01:02,417 --> 00:01:13,292
For the fabricated WBIC design, the outside diameter of the water inlet and outlet pipes is 3.5 inches (88.9 mm).

12
00:01:13,292 --> 00:01:18,875
It has a B-side rectangular cover casing door that is secured using hex bolts.

13
00:01:18,875 --> 00:01:29,292
In the cast WBIC design, the outside diameter of the water inlet and outlet pipes is 2.8 inches (71.12 mm).

14
00:01:29,292 --> 00:01:36,792
It has a B-side rectangular cover casing door that is secured using socket (Allen) head screws.
