Well, lots of cars still have timing chains. They last longer than belts.

That's something to think about for this Mustang hybrid conversion - how

With the gearing Ben could avoid the second

I do like the idea from a mechanical elegance perspective...but the second
motor also gives more oomph

Chains are very efficient. If you enclose them and they have lubrication,
they last a very long time. They are also relatively inexpensive, and lend
themselves easily to changing ratios. I suppose their main bad point is
noise, and the need for an adjusting idler to keep noise low. But

Just to follow up on this: I spoke with Bill at HPEVS this afternoon. I still
don't think he'd be willing to sign off on the project considering the
uncharted territory I'm heading into, but he was also rather more encouraging
with this latest round of changes.

So, as I mentioned in that previous post on air conditioning, I was at my shade
