Antigravity Lithium Battery Install – Porsche 991 Turbo S

Freak, Cam. Is every post on your blog about some car crap! Hey, thanks for noticing. But it’s not just about cars- it’s about health. Many of you know I’m big into weight loss. I think this video may help people lose weight quickly and safely. It’s not a diet, it’s a lifestyle change.

So you want to lose a bit of weight, eh? A lithium battery might be just what you need! They’re not cheap, but the weight reduction is legitimate. Spoiler: I knocked off forty three pounds by switching from a lead-acid to a lithium battery. Forty three pounds!  This video also demonstrates the removal & installation process of the battery in a Porsche 991 Turbo (as always it was more difficult than I thought it would be):

If you watched the video then you’ll know I had to do a bit of cosmetic surgery, but I’d call the operation a success. So far the battery works as advertised- weighs less, starts right up and the car drives great. I have negated he additional weight added by with methanol kit (& actual methanol) and my fire extinguisher. As I mentioned before, they are pricey, but a lithium battery is a pretty easy win!

7/13/2019: I decided to remove the battery when there’s no current concern about weight reduction. A couple of times in the last month I’ve had the PCM cut out followed by multiple dash errors (i.e. steering fault, PDCC fault, etc). I think this may be related to the battery but I’m not certain (seems like some type of power surge / drop). I removed it today and reinstalled my tune so we’ll see how things play out.

Rennline Fire Extinguisher Mount Install – Porsche 991

Safety first! I have never kept a fire extinguisher in any car I’ve owned. Even though I’ve never had a car fire I’ve often considered installing in some type of fire suppression device. With the addition of methanol into my car I figure I’d better not push my luck too and so…

I picked up a Rennline fire extinguisher mount for my 991 along w/ a 2.5 lb H&R Performance extinguisher w/ Halguard (if you’re interested you can get your own here). I opted for a Halguard model – this shoots out a fire suppression gas as opposed to a fine powder (not big on powders after I had a fire extinguisher blow up at work once).

The install was a bit more complicated than I imagined but I’m pleased with the results:

Helpful Hint: If you install a similar setup in your car I’d recommend a bit of practice. You’ll need to be able to release the holding clips and remove the extinguisher from its cradle quickly all while sitting in an adjacent seat. When fighting a fire, remember the P.A.S.S. acronym. Pull the pin. Aim at base (closer proximity is better). Squeeze the trigger. Sweep side to side. Hopefully you don’t have a fire in your car (or anywhere you don’t want one) but it never hurts to be prepared.
