Nice! I saw you said you where at 205whp as well at 2400lbs not a bad ratio. Car probably feels pretty fast now.

Got any dynos or done any 0-60 1/4mile 60-120 testing?

Got a build thread?

Here's my Braile 9 lb battery tied down with a strip of 1" wide 1/16" thick aluminum strap. Anchored to two rivnuts drilled into the battery pan. Lightest battery tie down system I've seen

Damn that's FKing awesome! Im at 2465 but I have vacation in 2 weeks I will be hitting the treadmill again.

Are you stripped out? Do you have a build thread to see your path?

Again my goal is to still stay stockish looking meaning no stripped interior.

Can you get a better closeup of your setup looks good from here. Im just going to redo my design in aluminum instead of steel should get me down to 1/2 LB at most!

Yeah, I'll snap pics tonight when I get home. That was an engine bay shot I had on my phone

SuperTom: some strong synthetic material flexible ribbon shouldn't be even lighter?

86TOYO2k17 · 09-04-2018, 09:07 PM

I’m just going to use a AAA battery and a piece of gum to hold it down and beat you all.

churchx · 09-04-2018, 09:12 PM

Hand-crank starter, especially left out after engine is started, will result in even more weight savings! no battery (and no starter motor) = lightest battery!

well not sure if you know but my design is super crazy sturdy so its worth the 1lb weight it adds. Its a cradle for battery to sit inside. Then I use the stock tie bar which is light to hold it down. It will not move in any horizontal or vertical direction. Pushing or pulling on it just moves the car instead. Had a nasty situation about 10 years ago where my pc680 came loose and shorted out bad on the firewall sparking and shutting everything down.

Anyway just want to remake the design with aluminum instead of steel with stuff I can grab at home depot.

This was how it looked before I cut the sides down

Finally got around to getting my underdriven fensport water/alt pulley and fluidampr pulley on. As well as my cf dss driveshaft, and jdm underpanels. Got lazy/ran out of time for the velox trans tunnel panels.
Car is pulling hard now. Puts you into the seat.

Although to be fair I did reflash to my revision 7 from 6, since now that it’s cooling down again hoping my 1IAM won’t keep dropping. Either way car is feeling good.
