Re: higher temps issue
Your engine temps will rise when running a supercooler and iso system. The supercooler impedes airflow to the radiator, which ordinarily would reach it when running a stock H/E or LET H/E. The iso system only adds to the reduction in engine cooling capacity. Since we separate them in efforts of reducing IAT, it adversely increases engine temps slightly.
Prior to adding my supercooler and iso system the max engine temp reached was 201 F, needle resting on the bottom half of the mid line or below it mostly. After the install, the max engine temp has been 209 F and the needle is consistently mid line or above.
This is why we need a lower T-Stat and LET fan programming, at least.
