Subject:25 MPG Wasserboxer!

Hi all,

I put a Boston Bob 2.1 engine into my '85 Westy and, after the initial
break-in, drove it to Virginia, Tennessee, and North Carolina (I'm in
Virginia now).

Anyway, because the engine was still fairly new, I kept the highway
speed down to a max of 51 (under 3,000 RPM) and didn't run the air
conditioner.  I avoided any fast starts and didn't lug the engine and by
doing so, I "Averaged" 24.92 miles per gallon (confirmed by GPS) from
Thomaston, Maine to Abingdon, Virginia which was just over 1,000 miles
with the route I took.  The inside of the van was pretty well loaded, too.

For those interested in the configuration (I'll make a full
report on that after I get back to Maine), I'm using the entire 2.1
intake system (snorkel and all) with stock 1.9 wiring.  The 2.1 AFM
works great with with the digijet harness.  On the trip down, I used the
stock 1.9 ECU with a 1.9 distributor set to TDC.  The tires are 185 14
C2 Hakkapeliittas with 40 lbs in the fronts and 50 in the rears.  The O2
sensor was disconnected.

I haven't accurately checked the gas mileage since getting here as I've
been using the air conditioner, changed to the 2.1 "Digijet" ECU
(performance ECU) and have been doing a lot of mixed driving ... mostly
in town driving.  It appears that I'm only getting about 18 mpg under
such circumstances.

Where I'm staying, I don't have an internet connection so communication
with you guys will be spotty at best.  We'll be attending the West River
Westies event in Vermont on the way home and won't be back in Houlton,
Maine until mid July.

Mike
'85 Westy 2.1
