Does anybody have any personal experience with Spal or Derale electric fans fan/shroud kits. I need something that pulls ALOT of air. Derale claims 4,000cfm with their dual 13" fan/shroud combo and about 3168 cfm with the dual 12" fan/shroud SPAL combo. Spal seems to have a better reputation, specifications, etc. But is considerably higher than Derale....im just wondering if Derale is measureing airflow at 0 static pressure as SPAL does on all their specifications. Anybody have any of these brand fans?

Thanks,
