yeah Nakkas - 4" BUT....i did some initial testing this morning even tho it was only 19 degrees. took it for my usual 20km test run and got the tranny all warmed up - it never got over 180F at the lights and i never switched the fans on. so brought it home and let it idle in "D" for about 10 minutes without the new fans running. the temp creeped up to 230F before i stopped. oddly the temps gained 3 degrees everytime the ENGINE cooling fans kicked on and stabilized in between cycles (im guessing hot air from the radiator being blown back added to the ambient heat around the tranny). i then kicked the fans on to see what would happen. at the end, the result was the new fans only stopped the temperature rise but didnt bring the temps down. i then put it in "P" with the fans on and it crept back down to 185f before i stopped it (without the fans running the temp would not come down). so they are making a contribution as far as stabilizing temps but i can tell already its not enough to cool it down without some airflow on the road. im going to do some more testing of course to confirm what ive seen so far but im thinking its going to take three 6.5" fans with 550cfm each vs the two 4" units running 330cfm each. looks like i might be going back to the drawing board. if 3 bigger fans dont cut it i will put a second cooler in. this is proving to be a very expensive exercise
