I doubt I'd get any better than you did, and I might even get lower. Our mods and driving style seem to be fairly close. On my drive home from college I got 80.8 MPG going through the WV and VA mountains in 50 degree weather, and the next day it was high 60s/low 70s out and mostly flat, and I got 92.5 for that leg. That was back in May. 85 F vs 70 F outside temperature seems to be roughly 6%-8% improvement in fuel economy, but I suspect that weather has a larger effect around town than on the highway.

I'll have that same ~700 mile drive back down to college in about 5-6 weeks; hopefully the weather is nice and warm for that trip. I'd like to break over 90 MPG for the whole thing. 100 is a bit optimistic considering I have to deal with those mountains in WV and VA. The drive down seems to be just slightly more fuel efficient than the drive back home even though the net elevation change is around 30 meters IIRC over 700 miles.

I haven't had any issues with the meanwell other than at very low RPM, which I'm sure bypassing the rectifier would help. But even with 3 or 4 miles of no meanwell operation at 800 RPM driving the car still cranks and starts fine. I am planning on getting a deep cycle battery when this 12V goes, but this one is new as of last fall.

I got the same Arctic F9 for the 92mm, and ordered a Noctua NF-A6x25 FLX 60mm fan to replace the stock one. I figured since I need an adapter from 3 pins on the Arctic to the 2 pins on the meanwell, I might as well order a splitter and run both fans. I could just splice into the wires, but I'd rather keep everything reversible. It was a little more than the Arctic fan, but it seems to be one of the best rated 60mm fans out there. Their 92mm fan didn't have the good specs that the Arctic one did, and I couldn't find a 60mm fan made by Arctic.

Was it one of those same HRP-600-15s for $29.99 + $13 shipping? If so, that's the same one I got. Fast shipping and works great.

Regarding mpg, if I combine both pizza delivery and non-pizza delivery together I think you have me beat.

...that is, until you put your foot down on your K-sight's gas pedal and feel the power, right? A k-swapped Insight would be too detrimental to my wallet; I'd probably lose all thoughts of economy if I had one and just spend all my time racing around and get maybe 25 mpg.
