fixed I read on multiple other m113k forums here Most likely the Heat exchanger pump.
I replaced it with a 010 bosch pump.
Added an extra heat exchanger
Added split cooling.
Result - 68 degree day.
Intake Air temp is now normally 15-20 degree above ambiance @89 degrees
Can heat up a bit more on Throttle
Also Can heat up a bit at the drive thru. got to 35 degree above ambiance. @102 degrees
once the car is in motion the intake air temp will cool down
definitely feels like there is more power than before.
