2007 Forester XT 4EAT-VTD
No negative impact thus far, but then again I use "mechanical compassion" on the driveline:I'm a noob on here, and a recent FXT owner. I am also a 4EAT owner, and wanted to know if there has been any negative impact on the AT since you upped the HP/TQ. Also, any specs on the duty cycles of the stock injectors with the bigger turbo/IC?
1. No power braking
2. I rarely hammer it in first gear
3. I rarely allow the tranny to shift under full throttle/boost
It's like when I had my '06 WRX with a 5MT - there were guys who would break the tranny with minimun mods and guys who were putting down over 350 WHP and never had any problems. Driveline survivability is almost entirely dictated by the behavior of the driver.
I don't have the duty cycle numbers, but with any VFxx turbo the stock injectors are usually not a limitation.
Thanks again for taking a look and commenting!
