My new econobox! (2000 Kia Sephia 1.8I4 16V DOHC 5 Speed)

[dirtydave]

Gottcha.. I just need some good screws and a new blade for my saw. and paint.

Going out today to get some speed VS MPG readings and some coast down testing.
I have to do it right this time so the mods can be proven.


I love this car and messing around with it. Friends and family are convinced I have gone crazy. Gas is the cheapest I have ever seen it and I am still pushing hard trying to improve and get better numbers. The 50MPG goal is close yet so far away lol.

You must be young or I am starting to show my age.

When I was a teen regular unleaded was .99 cents a gallon. Leaded was a tad cheaper IIRC.

Back on topic, I love what you have done, keep it up!

[dirtydave]

When I started driving gas was $4. I worked two jobs to put fuel into my $300 87' Volvo 740 turbo. And drove fast and fun.

[dirtydave]

Coasting distance is wayyy less and I'm only getting like 40-42MPG at 55-60MPH.

My normal coast start spots are thrown off. I keep coming 5 feet short from the stop sign or my parking space.

One road I normally go down I can start at the top of the slight hill at 25MPH and hit 45MPH at the bottom, a right turn on green and stop at the left turn light another 1/2 mile under 5MPH before hitting the brakes. I was only at 35MPH at the bottom and wasn't fast enough to make it to the light. P&G is basically useless unless I am going downhill. It has much more road noise. It will not get up to temp on my 20 mile drives. 22 miles today it only got up to 173*F. It was 70*F and a little wet this morning.

On my route I have a long downhill section on the highway I speed up to 70MPH and hit the kill switch and I have 31 seconds before I hit sign near the bridge. with wheel covers, belly pan, full grill block, folded mirrors, 55PSI. It takes about 24 seconds.

It seems like now I am going to be moving so this tank will be less then normal. with 315 miles on half a tank I am doing awesome. Lots of short trips and full car loads ahead. It has already started I have three computer towers in the trunk now.

Lets see If I can make this tank last and replace all the aeromods before the next tank with colder temps and a new route to work... Why does life have to get in the way of ecomodding?

I will be pushing hard for maximum FE as always! #!

You know you're an ecomodder when...

Last tank was 442.4 miles with 10.648 for a decent 41.55MPG This tank had No wheel covers, no grill block, no belly pan, I took three trips into the city. And many short trips. Weather is getting colder. So not bad not bad. I know how to drive this car now!

Seafoam in the last 2-3 gallons. I also hit the redline in every gear at WOT. New top speed of 107 mph!!. Tested on private property. !!

this tank was also 50-65 P&G for the highway portion of my trips. And the scangauge is telling me 41.1 mpg so it seems it is dialed in and very accurate!

Next tank will be colder temps, a new home with terrible parking, a new route to everywhere, and a shorter trip.

Unfortunately I am still in the process of moving and am very busy with work all at the same time!

so aeromodding my KIA has taken a backseat yet again. Not to mention my grandfather has bought a 81' el Camino he is fixing up for a winter beater and keeps asking for help with it.

Gotta snap a picture of the factory airdam on the 81'

[MetroMPG]

81 Camino as a beater? Not worth saving?

a new route to everywhere

That's actually one of the biggest challenges, no? When you know a route, it's so much easier to get great MPG.

And thus my title: I am the master of the Spaulding Rally. I know every rise and dip, every curve and bump. Whatever time I leave the house, I can adjust my mpg to get to work on time.

I found a good road to do some testing. I drove around for 40+ miles for work before this. All highway, all 60-45 P&G,
Engine coolant only got up to 147*F
Air intake temp was 67*F
I set the cruise control for what my GPS recorded at 55MPH

It is a 4 mile two lane road with a 1 mile long lightly traveled bridge with a tree line on each side.
Very Quiet. Weather was 50*F 0 rain 0 wind 0 traffic
ScanGauge was spot on last tank so hopefully the numbers are correct you see here#!

I did 10 runs 5 north 5 south. I sped upto 55 MPH hit cruise, as soon as my front tire hit the bridge I reset the Scangauge AVG and wrote down what it was as soon as my front tire hit the other side of the bridge.

It had a slight bump so it was easy to look at the scangauge at the correct time..



North: 42.4 43.5 45.6 44.2 45.3
+
South: 41.4 44.7 42.2 43.2 41.7
=
434.2 / 10 = 43.42


So my KIA gets 43.42 MPG at 55MPH in the "stock" form it is in now.
All of my upcoming Aeromods will be judged against this number.

Awesome#!

And My speedo is wrong when compared to GPS.
IT shows 57-58 when GPS is on 55-56



Can anyone help me do the math for what my odometer should be reading?

[Daox]

Good baseline testing. What mods do you have planned?
