RE: Mileage (was "What car to buy")
Item Subject: cc:Mail Text
I'm getting better mileage, surprise, since installing the IA Stage
III chip on the 91 200 TQW. Was averaging 18.5 ~ 19.0 in city driving,
and this has improved to 20 now. Last highway mileage I saw was
23.5~24.0, and I'm curious to see if this goes up as well.
Guessing that the chip, in that it has added a good bit of advance to
the ignition, gives more thorough burning of the fuel here at Colorado
altitudes. I thought the Motronic computer was smart enough to
compensate for the altitude, but it appears some more advance doesn't
hurt at all.
As a side effect of the hotter burn, the oil and coolent temperatures
have increased somewhat with the chip upgrade--now within normal
operating limits. Were running on the cool side (oil temp needle
barely got off 60).
BTW, I've taken this car up to 155 MPH, it had a little bit left,
maybe 160, so who is taking an aspro 20v 90 to 155 as well? With 100
HP less, how can the aspro 20V 90 offer that much top end?
Returning to the original thread, whether to go with the V8 or I5
20VTurbo, if you are doing any mountain driving, you'll want the turbo
to maintain rated HP. The turbo engine also gives you big HP potential
with a chip upgrade. I5 block is bulletproof. Love that turbine
whistle as the turbo spools up.
For 0 - 60 MPH stock fun at sea level, the V8 is bound to seem
smoother and more powerful.
