[QUOTE="Rojas, post: 31703, member: 2183"] THe "Finned flywheel" is actually a centrifugal fan. Works at high static pressures. The best advice is to go find the OEM setup and put it back in there. If you insist on trying to go electric I think you'll blow a bunch of cash trying to make it work. Maybe someone makes a well engineered kit that will git the job done. That's your second best bet.... Some comments about what you've done so far.....I don't know your fan sizes but the cond fans look to be ~8" or less. You need bigger and you need to pull through the full core face. No ram air on a bobcat.... Two 12" fans are liable to give you allot more air. Build a box to act as a plenum and mount the fans to that. Get fans that will work at hight static. Probably around .7". Don't look at CFM claims. There is allot of nonsense claims in the aftermarket and big CFM numbers are almost always open air where the fans not getting any work done. insist on seeing the fan curves [/QUOTE]
