Nice! weight loss is getting crazy. Def not going as extreme as you, but should be at about -85lbs after battery. Maybe -90lbs with fan havnt officially calculated it yet.

After I install mods I have now, prob get the jdm under panels and transmission tunnel cover might add 5lbs but make the underside look real clean and add some good aero. Then I think I can justify a CF DSS to push me over -100lbs weight loss.

You gotten dynoed yet? Or done any 0-60 1/4mile or any other tests? Would
Be interested to see what your running with that much weight loss. -300lbs should be roughly 20whp equivalent.

Yeah I did the CF DSS I like the quickness off the line really goes with the lighter wheels and pulleys all together. If you check my other threads I made a wind blocker for underneath the rear bumper it only added 2lbs using coroplast. Im thinking of doing the tunnel area next should only add 1lb tops. Wont be as durable as aluminum but many people on the ecomodder forums have success and its only $9 for a big sheet.


Just get the cheap $9 tender its low amps which is what you want for the Shorai batteries.

Nice I had 3 harbor freight coupons for this. got the tender, cutoff tool, and 6” magnetic tray 36$ shipped.

You’ll have to let me know how your tunnel panels workout. The ones I’m looking at are 160$ with all hardware looks really nice, but I can see it being an easy diy

I wonder if I can get all the hardware and brackets you used for the mount, and the heat shield wrap al on amazon? Save me a trip to Home Depot.

@SuperTom

So I found all brackets on amazon. About to order it.

I don’t understand how you fastened the battery cage, you used 2 10mm bolts are those bolted into the the battery bracket holding down the cage or does the cage just sit around those and it aides the tie downs from keeping it moving? It looks like the 2 side brackets you cut cover up the two holes on the middle bracket.

I just went ahead and ordered the Mishimoto slim fan setup in black. I have off work a week in mid Sept and will accomplish this. Im hoping to save at least 5lbs with the driver side fan removed (won't need since I don't have AC)


Also looking for some kind of sound deadening on the firewall?? for 6lbs and will tackle the remaining sound deadening in the car for another 5lbs.


Too save another 15lbs that week would be a great accomplishment would put me at ~2460lbs!

Just got got the shroud installed. Didn’t weigh the mishimoto, but the stock one was
7lbs 5.4oz , so no weight loss....

Pretty much got my shorai Mount all set to go, prob mount it this weekend. Did a little differently, no power tools required and cheaper too.

sucks no weight loss with the mishimoto setup. Again I'm going to run mine with one fan so I will lose something there.

Cool cant wait to see your mount. Will be awesome if its lighter. I think mine after cutting it down was only ~1lb


I'm also going to work on getting rid of the sound deadening in a few weeks and just keep carpet so it still appears stockish. That's really the end goal appear stockish and DD'able but light as possible

@SuperTom

Production quality a little low but sturdy and secure all you need.

Yeah its really sturdy once you bolt it down. Looks like both designs came out to nearly the exact same weight!!



I actually shaved another 10oz after cutting down the side walls to about 1/2" I found is all you need. Good Work!

[86TOYO2k17]

Header back -16lbs, losing spare / tools -30lbs and battery swap -24lbs. -70lbs so far. Thinking rear seat needs to go next. Then maybe new driver / passenger seats and or DSS CF driveshaft. That should get me to a solid -140lbs with out sacrificing any DDing comfort. Then maybe I’ll save up and supercharger in a year or two.

Well I just got my Mishimoto kit in and if your numbers are right looks like they are exactly the same weight. It looks like I will shave 2.75 lbs by only using one fan. I was hoping for more but I was taking a wild guess on this project maybe Ill find a useless bracket or something on my install journey.

You could probably just remove the stock driver fan and save the same weight.

The mishimoto is sweet though and hey if I ever go FI in the future it will be there

[86TOYO2k17]

I think I got you by about 6oz, that paint, foam, heat shield, battery terminal extenders add up quick. Look at my 1st pic mount 13 3/4oz yours 1lbs 5oz not painted. I probably used a little more foam and heat shield though. Got kind of carried away.
Mounted it and took her out for a spin. Thing is more secure then stock mount. Looks almost oem sitting in there lol.

Didn’t see you said lost 10oz at end post. So pretty close. Thanks for the ideas though.

[86TOYO2k17]

Fanshroud was a little disappointing but she does look beautiful sitting in there and a fun little project to keep my modding addiction happy for now.

1lb .5 oz , plus I just realized I had that stock mount on it too! I think I'm going back and redesigning this with spacecraft unobtanium just to beat you!

@SuperTom and @86TOYO2k17 by Saturday, my 13 brz limited will weigh less than both your cars, i should be at 2400lbs even. I will know the final count on Saturday. Yah buddy! Lol
