04 2.5XT 4EAT
I was wounder if anyone knew what the max wheel horsepower the 4EAT could handle or an estimate.
If pliad is right then really a cooler and Synthetic ATF won't make much difference in preventing failure. The extra heat a 400 HP develops is not gonna be much bc you can't keep dumping HP into the thing for longer than 15 seconds at a time. Now if you are gonna use 400 WHP to go up a 5,000 climb with WOT...yea.I heard getting an added cooler, switching to fully synthetic fluid, and getting a valve body upgrade are your best upgrades. If you want to build more boost off the line then an upgraded TC would be helpful..
It doesnt look like anyone has done that resistor mod other than the OP of that thread. Anyone try and verify this?Be wary of an expensive valve body upgrade... apparently all that can be done to the direct control 4EAT in the 04+ FXT is for them to put a $2 resistor. Hardly worth the ~$600 you'll shell out for it. Read up: http://www.subaruforester.org/vbulletin/f89/valve-body-upgrades-4eat-38896/
