After a rather 'spirited' commute this morning to work:
Top is LIM (post intercooler) air temp in bypass (not flowing fully through the core), bottom is trans temp:
If I were to close the bypass, the LIM air temp gauge would drop into the 80'*, as the air would be forced through the core as if it were in at least partial boost. Notice the AMP TEMP.
Well, let'* call it a horsepower amplifier, shall we?
Body of the SC 30 seconds later:
Nosedrive temperature at the same time:
Nosedrive is normal temp or at least a little lower. SC housing temp is FAR lower than it normally is without the intercooler. My SC housing after running boost is always (or used to be) hotter than the nosedrive. Granted, my hood vents, high speed fan override, and coating help, but this was a significant change mostly due to the intercooler. The intercooler itself is thermally isolated from the LIM. It doesn't actually touch it anywhere, so this is a result of the temperature of the air in the LIM keeping the LIM temp down, in spite of the engine coolant running through it. Remember the S1 L67 LIM has a large water passage running right down the middle of each bank in addition to the cross flow from head to head.
My temp probe is less than a half inch from that long passage with coolant.
