I was wondering if someone was going to mention that. The starter is a backup for the 12V system to start the car in the "unlikely" event the IMA battery goes kaput. VERY weird sound to hear it for the first time. I let my IMA battery sit for about 4 months on my old Civic Hybrid and it went down during my absence. When I jump started the car I heard the starter for the first time, really weird when you're not used to it.

MetroMPG - it does have a pulley system, that's what the A/C runs off of It could easily be converted to accomodate an alternator if someone has machining skills for making a good bracket, then of course is the task of wiring it in........

Cool. This is neat info. As to why I wouldn't just get a regular Insight? Good question!

Probably a combination of the hypothetical prospect of getting a deal on a dead IMA vehicle, plus the challenge of retrofitting & modding the stuff to make it go without it. And in part I started thinking about this because there are just no good VX's around here any more. Too high mileage & rusty.

Not that I'm shopping or anything. Just kicking around ideas.

Hey! What is wrong with a rusty VX? The rust is just not detrimental to operation.

You're right. Actually it helps make it lighter for better FE.

I think wiring it in should be pretty straightforward (the regulator is built in). Connect the battery to wherever the DC-DC converter would otherwise be. Most alternators have a ground connection and a heavy guage connection to the +12V battery lug (or it may even share a heavy cable with starter). Then there are sometimes one or two more connections (like a fused +12V feed from the ignition switch to turn the field on/off, and/or a wire for an 'ALT' light. Anyone?

I thought that sounded high. Many sources (new and old) have it at .25. For example:

While you're de-hybridizing it, you could always go the other way and make a straight EV out of it, but that's OT so nevermind.

I should have been clearer with that figure. The .31-ish refers to my car's calculated Cd with current aero mods (grille block, wheel skirts, undertray, mirrors reconfig'd, but without the partial boat-tail). From .34 unaltered.

Man, if I could get the Blackfly down to the .25 Cd of the Insight, I should see (very) roughly 12% improved FE at highway speeds than I can get currently. And that would still only have me at about 66 mpg @ 55 mph @ 20C.

Oh sorry metro, my bad. I misread it as "the Insight Cd is .31" but you clearly stated you meant the Blackfly. :/

BTW, Your efforts are very inspiring. Keep up the good work.

Now if I could figure out why I'm getting an FE drop in the Passat lately...

Have you tried driving around backwards? Remember that Pinto study that showed it's Cd was better in reverse?
