2006 Forester XT
When I heard the 2006 Forester XT makes the same peak torque as the 2005 version (235@3600) but was rated 20 hp higher in power, I assumed (along with many others, I think) that Subaru was merely assigning a more realistic power rating and didn't really change much with the engine.
But I was wrong. According an SOA press release: Quote:
BTW, Subaru has now begun referring to its AVCS as "i-Active Valve Control System" and calling its 2-stage variable valve lift system "i-Active Valve Lift System." What's with the "i-" stuff? Intake? Intelligent?

Jon, My guess is that indeed the FXT will be no more powerful than the older cars, they just made changes to make it more capible of meeting the durablity requirements of the EPA while also cleaning it up a bit more.
Honestly the stock WRX turbo was so far out of its range on the FXT I can't see that as really having the 100K mile duriblity for emissions equipment that the EPA requires. Which likely subaru is starting to find out on its own. Lol 9.5-9.8:1 stock A/F ratios on boost. |

The engine and gearing changes have also bumped up EPA fuel economy ratings, especially on the AT model where the gear ratios look pretty high:
05 MT: 19/24 06 MT: 19/25 05 AT: 20/23 06 AT: 21/26 I'd expect the 06 WRX to get the same or maybe even better gas mileage than previous models even with the bigger engine and more power. |

The 05MT and 06MT gear ratios are exactly the same. The difference in mpg is due to aerodynamics and the difference power curve most likely.
The 05AT and 06AT differ only with the final drive, it's now 4.11 instead of the 4.44 of the 05. Quote:

Gear ratios are identical to the current WRX ratios...How not surprising. Hopefully they stick the 4.44 final in the WRX as well, it will make a big difference.

I agree. The FXT's I've seen on a dyno show 230HP crank. STi's range from 300 to one I saw that hit 315 crank. My LGT was 260 crank IIRC. WRX's usualy turn about thier 227 crank rating. Dyno does a coast down measurement to calculate crank numbers.

Before you take a car like that in for smogging...drive like a mad man to get EGT's high enough to burn off any carbon deposits off of the air injector so that it can work well for emissions purposes...someone told me this was referred to as an 'Italian tuneup' :P |
