Listen I drive big rigs we have clutch fans on them and they are 30+ inches in size most are 33" and we lose 30HP with these fans, so come on Pontiacs little dinky toy flex fan doesn't even come in that ball park. I believe what was written by Pontiacman8 on HPP about this, his facts state as such 2 to 5 HP can be lost and he went on to write that it's more in tune of 2 HP. He's a professional GM engineer and strictly Pontiac and can build with his eyes closed. You want to talk or hear what he has to say go to HPP forums. I can't believe we measure moving air mass, it just reminds me of when I was 16 and believed if I waxed my car it would win the race at the strip.
