[QUOTE="Bad Company, post: 15665973, member: 141815"] The LC system is strictly there to cool the front of the case and front bearing housing of the SC and shouldn't be looked at as a method to reduce IAT2s. When you cool the SC with ice water from a trunk tank for the intercooler system, the case actually contracts in the front from this cooling method. On a hot summer day you now have 95+*F ambient air cooling the rear bearing housing of the SC and 35*F water cooling the front bearing housing. This 60+*F temperature differential in cooling methods causes the front bearing housing to contract too much, while the rear bearing housing is expending. The difference causes the rotors to make contact with each other at the front of the case, due to the differences of a few thousands of an inch in the centerline of the bearings housings from uneven expansion and contraction of the two ends of the SC case and bearing housings. At high boost levels the SC front bearing housing will see heat from the air exiting the SC. This can be as high as 350*-400*F depending on the boost and ambient temperature of the air entering the SC. These high temperatures allows a engine coolant based LC system with 170* F coolant entering the SC the ability to cool the front case to control expansion of the case and front bearing housing. It isn't the best method, but it works better than nothing. The best method to cool the SC front bearing housing and case is with ambient temperature coolant, which is what your stock intercooler system is using. This matches the rear bearing housing and SC case being cooled by the ambient air entering the SC at the rear. This leaves you with little options if you decide to run a trunk tank with ice water. The next best option is to fabricate a separate cooling system with its own pump, HE and small tank for the LC system of the SC where the HE uses ambient air to cool the liquid in the system. Doing this allows you to run ice water in a trunk tank for the SC intercooler system while retaining ambient air temperatures to cool the front case and bearing housing of the SC. By cooling in these methods you remove as much heat as possible without having to worry about a big temperature differential causing the SC case and bearing housings to expand or contract in an uneven manner that will cause rotor contact . With the trunk tank having it own pump, you can use the stock IC pump and IC tank to move the coolant of a separate SC LC system. You'll need install a small HE and plumb it to the the tank and SC coolant lines. This method keeps the expansion and contraction of the case and bearing housings even as possible, while removing as much heat as possible [/QUOTE]
