Any dyno operator dynoing a 4EAT transmission knows how hard it is to get a clean full throttle pass without kicking down into the gear below it. This transmission unlike the 5EAT isn't manually selectable. You must drive the car in the correct gear and feather the car past 4000rpms then roll into the rpms slowly. If you could lock it up sooner you would see the massive torque converter spike we are accustom to seeing with auto transmission Subarus on the dyno.

This Forester is a great daily driver that is whisper quiet and packs a punch without compromising in driveability. Like most of the VFxx 4EAT 2.5L's we've done - this car will break loose 265's in 1st and into 2nd gear from a roll. Based on customer feedback even with a slow footbrake launch this setup is capable of very low 13's @103-104 even with the 4EAT transmission.
