Description: Picked up Feb 25, 2009 with 127 miles on the odometer. Filled tank at 167 miles.

Note: the following measurements were done prior to truing up the Scangauge, so they are about 15% high of actual performance at the time.

Basic performance measurements in 5th gear, stock car, 7 mile run, no stops, low wind, small hills:
40 mph, 2000 rpm, 49.0 mpg.
50 mph, 2500 rpm, 41.5 mpg.
60 mph, 3000 rpm, 37.0 mpg.
70 mph, 3500 rpm, 31.5 mpg.

40mph to 50mph pulse and glide, 49.7mpg.
50mph to 60mph pulse and glide, 45.5mpg.

Coast down averages, 5 runs, slight wind (10 mph)
70mph-60mph: 9 seconds
60mph-50mph: 10 seconds
50mph-40mph: 13 seconds
40mph-30mph: 18 seconds
30mph-20mph: 21 seconds

EOC works good, 60mph - 30mph coast is a good speed range, I can start in 5th gear and speed up to 60mph again. The car will need a engine kill mod to keep the Scangauge running.

Pulse and Glide is easy, in a 35mph speed zone, coasting with engine on until you get to 30mph, then engage in 5th gear and power up to 40mph.

50mph is a good cruising speed, 45mph is even better for rpm. Need a gauge to tell which gives better mpg.

On flat roads in 25mph zones, you can putt along in 5th gear at 25 or 30mph very nicely.

The motor runs 3400rpm at 70mph, which seems a little high, but is managable. 64mph is a much nicer highway speed, about 3000rpm.

Planned Mods: Some things that I am thinking about doing:

fog light blocks
lower grill blocks
upper grill blocks
servo grill opener
mirror delete, interior mirrors or smaller exterior mirror
body pan
front air dam
wheel boat tails
tire spats
catamaran between wheels
radius aft end of wheel well
front wheel arch gap fillers
seal panel gaps

vent in small window

low viscosity synthetic oil
warm air intake
engine kill switch - fuel injector power shut off
higher 5th gear
alternator delete
low rolling resistance tires
narrow tires

weight reduction

Cd calculation
Performance calculation sheet

aftermarket cruise control
cruise control based on engine load

inflate tires

I will not do all of these things but will start with a few and think about the others.
