Remember the white WRX I brought with me to RA and recently traded in on the STi?

I was at the dealership today (no resolution to problems) and that thing was STILL there.

They're asking $22k for it. Yikes! It's a 2004 with 25k miles on it and I paid $23.7k for it new!

But it gets worse.

Poor thing has some tacky black "swoopy" graphics on it now. I took pics with my cellphone and will try to post them when I can.

Also went to Imagine Auto to put the car on the dyno. Dunno if I mentioned that it's WAY down on power compared to Gary's equally stock 2005 STi. Sheridan took my car out for a session at HPT in Gary's run-group and Gary even held up so Sheridan could catch up, then ran away from him on the straights.

I couldn't believe it! Then Gary offered to let me drive his car, which I did. Two laps later I pulled in, feeling sick about mine. His car pulls in 4th like mine in 3rd.

However, the dyno says mine's pretty close to making what Subaru says it should, assuming you can add 20% to the wheel numbers to account for AWD drivetrain losses. Peaked right at 250 horses at the wheels at 6k.

The dyno might've pointed out a major problem, though. It's supposed to make 300 lbs of torque at 4k rpm. And that's supposed to be where peak torque lives. Not so in my car's case, and that's the area where his car is killing mine.

At 4k rpm mine's making about 220 lbs at the wheels and keeps climbing until it peaks at about 240 lbs from 4700 to about 5300, where it starts falling off.

Isn't the ideal air/fuel ratio something like 14.7 to 1? Mine does that near the bottom of the graph (about 2200 RPM) but by the time it reaches 3k, it's down to about 13.5 and drops steeply to about 11.2 at 4k and barely above 10 at 6800 rpm. Those numbers look kinda scary.

And my fuel economy has gotten "too good". 22 mpg, driving it like I borrowed it from you and you said "Have fun!" <g>

Anyone I've talked to about it has said they can't get 22 mpg babying theirs.

Will make arrangements to get Gary's car on the same dyno as soon as possible. After he blows my doors off at MAM next weekend.
