Any ideas of the engine/turbo and fuel specs?
Theyre restricted yeah, and probably not running a great deal of boost therefore not creatng too much heat.... so maybe there just high comp builds, big revs with lots of inconnel on fuel that has good det resitance??
The coolers aren't really that small either imo. Everyones obviously seen much larger coolers but there generally tucked away behind bumpers and grilles in relativly little airflow, quite the opposite with these ones it seems.
