Unit-02 Red Honda Insight

[Daox]

Sounds like a great idea to me. I'm looking forward to seeing it finished up and hearing more results. Thanks for sharing!

Then when I get home I could top it off with the grid charger.

Too fun.



I used my tired Insight pack in reverse: rarely used assist, but I used regen (when I had to) to feed the pack. I figure that regen was powering my 12v stuff at least.

Be sure to count the cost of electricity used, as the mpg numbers will be artificially high. What is the cost of electricity by you? If electricity is cheap, this may be a good way to offset the cost of the conversion.

Awesome stuff you're doing with the car.

Yes, that's exactly what I had been doing for the last 2 years since I bought the car. Clutch switch turned on almost all the time, and then I have an Auto-Stop I would use for Engine-Off Coast. The IMA motor would restart the car, but I never otherwise used assist.

But the pack got worse and worse, and so recently I removed it so that at least I'd save some weight. The new LTO setup changes the game completely.

Electricity is cheap here, and at most I could expect to only put 1 or 2 kilowatt hours into it. But I haven't got this setup yet.

But I'm wondering what I should do for max FE? Ecky for example put big sheets that go under the whole body of the car.

A thought was I could use coroplast I have left over from the Black G2 to recreate the old G1 pan. Then, because it attaches easily, I could do some ABA testing. A testing regimen would be like I accelerate to 10 mph then throw it in neutral and see how far the car goes before stopping. But aero drag is most prevalant at higher speeds. I could try like getting to 40 then at a certain point on a road I could throw it in neutral and see how far it travels before hitting like 25. But then I'd need to be going down this road quite a few times with no traffic there. I'd also need a suitable road.

Anyone have any ideas how I can test?

We know from a number of published wind tunnel research projects,that any paneling will 'show.' Honda's already done the pick and shovel work,so anything we do is just small incremental improvement.
If you ever do a boat tail later,any upstream smoothing will help deliver the highest quality airflow to the rear.
The boat tail though,is the moneymaker.On the open road.

It's been sorta cold here. Actually froze a couple nights ago. I've been getting bad MPG, but I have also been driving it like I stole it. I have to drive so much these days I hate it. But I still get over 60 MPG, so at least all the mods I've done are still helping me.

Today I hope to build a grid charger harness (finally) and do the 30% extra current hack for the IMA system.

Vredestein Quatrac 5 165/65 R14
I heard they weigh 1 pound less than the RE92. I'll be the guinea pig. I was on RE92s at 61 PSI, I just got these on here same pressure. Their sidewall max is 51 whereas RE92 is 44.

[Ecky]

The tread is a little narrower. Can confirm they're very light. I have 185's on mine.

[Natalya]

Okay I've had them for about 2½ weeks now. At 62 PSI they MIGHT have a small hit on MPG but the weather is incredibly variable recently so it's hard to tell is it the tires or is it the cold? Also, traffic has not been predictable.

They are barely quieter than RE92s at highway speed.

I have better traction, but I also have tire tread now. XD

LTO current hack is ruining my MPG.
Because the car goes vroom vroom now and you can actually accelerate.
So I waste energy doing that.

I've been trying the PHEV method of charging it most nights for a couple hours before I go to sleep. I've been writing some Arduino code to manage the charging automatically. I'll post when I get that finished and installed.

I divided my garage entry into a 2017 - 2019 entry and a new 2020 entry so the fuel log doesn't get too small to read.
