Thanks a bunch, freebeard! That was a great watch. I've always respected Sandy's opinion on things and have followed his Tesla teardowns with interest. The fact that he was impressed with the...

Cool The proof is in the pudding

Ahhhh! This makes much more sense, and is pretty reasonable to boot. Okay, let's go back to the data. I've attached a couple of choice Torque Pro logs. The first is the coldest temperature I...

Question More observations

Hey Ecky!

I first installed the insulation during the summer and have mostly used it in warmer weather. It basically shortened the initial warmup of the vehicle by 45s+ish, and helped it retain...

Cool One of my favorite quotes

Those are all classic signs the hybrid engine isn't warm enough. You'll definitely see gains by doing the engine insulation, both in fuel economy and warmup time.

So the correct solution is: do...

Thumbs up Effectiveness vs Efficiency

Hmmm... if *that's* your main concern, perhaps you'd be better off investing in a car seat heater and/or 12V electric blanket. Or you could really splurge and get a new driver's seat with heat/AC. ...

Exclamation Lessons learned

So the second version of the boat-tail that I did had the exhaust moved to be at the end just like this. Not only did I reason similarly (the low pressure would help suction) but also that the...

It turns out I got unlucky. There was a chance that my recent pair of trouble codes were just the temperature control valve, which was replaced and works fine. But the inverter coolant pump was...

Nor I. I tested all three configurations (no, stock, extra) and my mpg increased with each, by 8% and 2% (on a short 15 mi trip). Said differently, removing the stock insulation caused an 8% drop...

Red face The game is afoot!

Hmmm... that doesn't jibe with what I know about aerofoils on planes. Longer, thinner aerofoils do reduce drag, up until skin friction begins to dominate. However, real engineering is often about...
