Have you guys noticed how much that the 'tail on that EV-1 goes upwards ?

You can see it from the side of the car, but it is also even clearer on the 3/4 front picture.
If you follow the trunkline on the side shot of the car you can see how there is a definite upwards rise to the 'tail.

About the Saturn, you are lucky because your tires don't protrude much. You will be able to have some pretty flush skirts.

I didn't notice if your SC1 is a stick or auto.
IDK why you shouldn't be up past 40mpg already; the SOHC S cars w/ 5speed were rated for 40mpg stock, and I've read of lots of guys beating that. I had a '93 SC1 w/ a DOHC swap that I was able to get 36mpg in, mostly 32-34 w/o trying.
you might be running too cool also if your temp gauge is only at 1/4. do you have the brass ECTS in there? saturns should be running at 1/2 gauge.
I would suggest lowering springs and try to fit those 80series tires. I don't see why 45+mpg wouldn't be attainable.

It's a stick. I clicked on the his car's name and it took me to the garage for his sc1. The brass ECTS are a must. I would guess it already has that. I also have a 192-195 degrees F Coolant Thermostat (Napa Part #THM268)

In case you haven't noticed it's winter outside in the teens, 39 mpg is what GM claims for highway mpg, probably at 55 mph, not mixed driving in winter temps and 75 mph highway speeds. Sure I could hypermill but thats a pain. You can also view the fuel log and then I wouldn't need to explain.

My stock 93 SW2 got 36 mpg and you did all that work and only got 32-34? 3 previous Saturns all ran at 1/4 gauge stock temp.

No lowering springs man.

If you want a higher temp thermostat than 195 you can take the center pin out and grind it shorter. This will make it open at a hotter temp. I suggest using a thermometer to calibrate it in hot water on the stove, when your wife isn't home.

yeah, winter here too.
I remember seeing 40mpg on the window stickers when I was selling saturns in '02; the twin cam cars got 36mpg hwy.
my '93 SC1 had a '94 twin cam swap and a '92 header and a SPS exhaust and I hardly drove it gently, so my numbers are real world. I could get 36 if I was careful, and that's what they were rated for.
as for the temp, I have seen lots of S cars run at 1/4, but IMO they run better at 1/2 temp. if the ECTS is cracked or the wire is corroded, it might not give correct readings.
don't know why you wouldn't want lowering springs. S cars sit too high and could benefit from an 1" or so lower IMO.
regardless, I like what you're doing.

sc1 mpg was 39 for 1998 for some reason 40 all other years.

Yes I had the headers also on the 93 SW2 and 2 inch exhaust.. Had TotalSeal gapless rings. Had a diode on the MAP sensor to advance timing at low rpm. Other than that it was stock. It had some go compared to singe cam saturns. Diode didn't seem to help on sw1, haven't tried it on sc1.

I made a front skirt and tried it out, the wind ripped it off the first time I hit 55 mph. I was able to retrieve it. The rivets pulled out of the poly tube and the bungie cords pulled through the holes. Thinking of a better design.

That's the inventor's life. I like zipties where applicable because they're solid and quick-cut-removable.

What is the brand/model of antenna? I can't glean it from the URL you posted.

I've always thought the SC's would be sweet to aero mod.
