You mean you think that a high BSFC means higher efficiency? Try checking this web site for some more information about BSFC.

Good point - added to the weight reduction tip: permalink

Decreasing bsfc is exactly what we want.

The goal is to minimize the BSFC, which is a measure of the amount of fuel used to do a certain amount of work.

Minimize pretty much is the same thing as "decrease as much as you can" to me.

I think you just put it in a weird way that made it look like you were contradicting yourself between the two sentences.

The fact of the matter is that there is an optimal ignition timing for fuel economy. Frequently, stock timing is a bit retarded from optimal.

Still adding to the list. Recent additions:

- electric conversion - permalink
- reduced ride height - permalink

Tape / seal panel gaps - permalink

All those little gaps may not seem like much, but they add up. That's why all the bonneville race cars come sealed up like a coffin. There are many solutions here, including the use of clear tape or color matching silicon[e] filler. Others will adjust body panels to minimize gaps.

What a great list! But the above common typo/misuse (I assume it is just a typo in your case) drives me buggy. Silicon is for chips, silicone is for boobies. Oh, and sealing stuff up of course.

Ha! Good catch. Fixed.

On the alternator delete you might mention that a deep cycle battery could replace your old battery for only a little more $. Also this mod should pay for itself quite quickly If you are getting 10% better FE! A deep cycle flooded runs $90 - $150 not much more than a good quality starting batt. (120ah $49 at costco at end of summer season clearance)

Love the 50 mods!

On the windshield wiper delete, you can just remove the passenger wiper and leave the driver side there. I did this on my Saturn and it never hurt my vision in heavy rains.

Do you want to have defects that affect fuel economy in this list, such as a bad thermostat, or would you like to make a new list for them?

[MetroMPG]

That's a good point. I was thinking of making a single entry saying something about "general maintenance", and could include it there.

Also good suggestions re: wipers & batteries. Will add.
