I'll post the details of that tomorrow for review. In the mean time, since you like math so much, I'll let you explain how my flat radiator managed half the temp drop of one of your evap cores, with only 4.6% of the area. BTW, since I'm counting both sides of my flat radiator, I'm counting both sides of your fins :-) For the record, I AM just messin' with you. Now get out there and fly off that 5 hour minimum test time to cover your new redrive installation :-) Rusty -------------------------- so comparing that to the single radiator above 12,480/1696.41 = 7.356 sections 9 feet long or approx 66 feet of this tubing to equal one GM evaporator core. Now my airplane takes two of the evaporator cores, so all things being equal you would need approx 132 feet of that tubing. So unless my math is way off (always possible), Rusty, I would recommend saving your money for something like a custom radiator. FWIW Ed Anderson
