Point-by-point reply would take all day!
It's a
unibody car, that should have been evident from the pics and description, and from general car knowledge if ya have it.
Escorts are very similar to my car:
All four door panels <20 lbs.
Front seats 36.5 lbs each.
Rear seat bottom 12 lbs.
Rear seat back 13 lbs.
Bottom trunk liner 2.5 lbs.
Spare tire cover 3.5 lbs.
Spare tire 20.5 lbs.
Jack 4 lbs.
Headliner 4.5 lbs.
Carpet- who knows. I'd only go 20 lbs. on that.
Total 153 lbs.
Then add back:
1 gallon Herculiner 10 lbs.
1 driver's seat- stock 36 lbs; mini-van captain's seat no doubt even more!
OK let's keep the jack 4 lbs.
Spare is already a donut- 20.5 lbs.
Total 70.5 lbs. added back, or 82.5 lbs dropped.
There's only one antenna.
That plastic front fascia is quite light. Better be careful to use little fiberglass and resin or the new part will end up heavier!
The roof as a radiator? With that being about 3" from my head, so much for A/C delete.
Aero shell caps for wiper stub LOL.
A/C clutch on alternator? Have you seen how heavy they are? They require power to operate too. Why not just turn alt field off?
... What hard fans?
Better at least circulate coolant if the engine compartment is all sealed up. Or, better have a spare cylinder head ready for WHEN you crack the original.
Add a few extra batteries (at 30.5 lbs. each) for accessories... now you have no passenger carrying capability due to no seats, but you are driving around with extra batteries and the whole car weighs 20 lbs. less than it did before.
They say for every 100 lbs. dropped fe increases 1-2%. So 20 lbs. off gives us .2-.4% fuel economy improvement; at a baseline of 40 mpg that would bring us to 40.008-40.16 mpg. Yeah.
Exactly how do we determine what the skinniest tires that can safely be used are?
How does an electric brake booster save gas vs a vacuum booster? It's a little car, only time brake boost might be a factor is when extensively P&Ging, how about no booster at all?
Exhaust work that increases power does not necessarily increase fe. Most of that stuff is geared towards moving the power band higher... to rpm ranges where we won't be!
Xfi- how's the car coming?
