i think my tank will be about 50mpg because of the cold weather (about -15c average) and the fact that my engine never gets to operating temps and learning the lights is harder then I thought

[echo-francis]

the cold weather and the snow are really affecting my tank i have (again) to drop my estimation) i think i will do 40 mpg. ( driving in the snow means no p&g and no p&g means no mpg )

Nice job the on the insulation, is it weatherstripping tape?

[echo-francis]

yes

Great work.

Do you use the alternator for the short commutes? I doubt the ROI is there, but, a Lion battery pack would be neat to replace that tired old battery.

I really like the electric WP. I think it will eventually be the way it is done with all cars.

Does anyone have any power consumption numbers on mechanical vs electric WP? I would think there is a pretty fair difference at 2500 rpm.

One other question. Do you ever bike commute when the weather is better? Ecomodding a car is great...for when you need a car. But driving a car 6 miles in nice weather to class and back really is kind of dumb.

hi pete c

my battery died recently and I just buy a normal battery but I plan on buying a deep cycle battery (li-ion or normal) to replace my alt on short trip

the max power consumption of my EWP is 7.5a but when my engine is cold it run on/off cycles on 7.5a but 6volt. and recently i put 4 diodes on a switch to make it run on -2volt when i want

right now bike is impossible but when the warm weather will arrive I will study the possibility

last night i did a half alt delete. what I did is: I buy a small battery charger and remove my serpentine belt. I charge the battery at night . to test my battery range I just put my headlight on for 45 min and my battery drop from 12.4v-12.5v to 12v12.1v about .4v and I know that my commute take 20 min each way and my headlights takes more energy per minute then my commute because i p&g

i just drive to the bank this morning and i immediately feel more power in my acceleration

the bad side is that my cold start idle are a bit higher then before and I was already complaining about that

I would really like to drive the Mazda without any belt, but having a mechanical WP, this is impossible and stupid .

yesterday I went to a DIY garage to change my transmission oil. I replaced dyno juice by this:






you can see the removed frontal belly pan in this picture




here is the part without belly pan
