I've had my B4 for a couple of weeks now, only had a chance to take it out for a couple of decent runs the last few nights.
My opinion on the TT setup and VOD is still undecided.
Initially I felt that the main power delivery is too high in the rev range, it's unuseable in most driving situations in the city, you're doing 80km/hr already in 2nd by the time the second turbo kicks in, which seems to be at 5000rpm for me.
However, the first turbo does deliver good driveability for what it is, reasonable low end torque, but nothing you'd call "exciting".
Got me to thinking you've really got 2 different cars when you buy a TT B4, the car from idle up to 3500rpm, and the monster that emerges from 5000rpm to redline.
It's a 2001/02 vehicle, at that time did they have turbos that spooled up as early as they seem to do in current cars? Linear power delivery in stock unmodified cars was barely an option in a turbocharged 4cyl from my recollection of those days (i had mates with 99 and 00 WRX's). What we've got is Subaru's take on what you get in the current high performance turbos, power from down low delivered in a linear fasion (with a little more up high), unfortunately the trade off is a dead spot in the rev range.
I started off a little unimpressed, but the more i think about it, the more happy i am to be driving a TT B4, it seems like they were really doing everything they could with the turbo technology at the time to create the best driveability. Pretty iconic vehicle.
I could be wrong, happy to be corrected, i'm no mechanic so a lot of what i say above could be bullshit.
anyway, my opinion of the b4 is still developing, it's been a bit up and down, but i'm trending up.
