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!
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.
I’ve had my car back for a little over a week and I’ve been able to do some empirical testing. Hardcore scientific-level stuff. As I had mentioned, it felt like the car was faster than before but now I’ve officially confirmed it. It’s nice to be right. Also… Whoa. Momma.
Below I’ve put two runs side by side. This left shows the car in its previous iteration (stage 3) tuned for 91 octane. The right shows the car in its current iteration (stage 4) also running a 91 octane tune (w/ methanol). Watching the video shows how dramatically the top end tapers off with the old set up. I really wish I had made videos from every stage of the car’s development, starting when it was stock. But hey! At least I have something:
Fun fact: The current setup is faster than the previous setup using race ga$ (I used the “$” because it’s like liquid gold). You could almost make the argument that a stage 4 build is more cost effective since you only need a couple gallons of methanol for a three tanks of 91 octane gas gas (driving normally). Of course taking into account the cost of the stage 4 upgrades you’d just be lying to yourself… and everyone. You’d just be a big stage 4 liar. And it’s a moot point since I’m about to use race gas.
Stage 4 w/ race gas should take the car to yet another level!
Quirks thus far are really minimal. Under certain circumstances the car sputters a bit when it starts (allegedly this has to do with residual moisture present in the intake manifold). I’ve also seen some slight idle stumbles but I’ve seen that even before this latest upgrade. All in all I’m feeling pretty confident that this setup is bulletproof enough that I’m willing to pop in the race gas for a couple of days. I should have some updates next week.
The call of “more power” is strong… omnipresent. I have held out for nearly two years (although I harass my tuner, Sam, much more frequently than that). Eventually my passion overpowered my promise and I ordered in a shiz-ton of new upgrades. The excitement is definitely overpowering my shame (just kidding… I have no shame).
I caved in and called Sam. He hooked me up with some DO88 inlet pipes, 68mm VTG Turbos, straight pipes (the removal of the catalytic converters for the race is necessary, but they’ll be put back on afterward). And last, but not least, a methanol kit. This is a big last step but I feel like it’s been race proven at this point so I’m all in! 😀
Going in with eyes wide open from my past experiences helped keep me calm even when issues popped up. Broken screws that needed to be drilled out. Cracked piping that needed some mild repairs. Sam talked us through everything and gave us peace of mind.
I really enjoy working with my local shop. They are some of the coolest guys in the biz and they do bulletproof work (and I never get tired of saying that they are just a quick walk down the road). They let me come and see the progress and talk shop whenever I wanted.
There’s a big size difference between the old impeller and the new one (top left). I can’t wait to see what she can do. Even with just bigger turbos the top end should have filled in a bit but why stop there?
Everyone should have a methanol kit. Install was pretty painless (for me). The only elements that give the methanol away are the Devil’s Own reservoir in the frunk and the snow boost gauge on the dash (I was absolutely okay swapping out the clock).
After the installation was finished I consulted with Sam who explained how everything should work. He gave me a slew of cool tunes (he said I could use the 93 octane w/ methanol tune and it should be fine- more on that in another post). We filled the meth tank up with a couple gallons, added in some water (16 oz / gallon), primed the pump, installed the recommended new tune and Dagan and I took her for a test drive. Wow. No issues out of the gate. Hoses stayed on. No explosions. I wasn’t 100% sure what I was experiencing. And then it hit me: the top end of the car’s power band was a monster. Normally the car would be losing some oomph around 80 or 90 mph but with the new turbos and meth it just pulled and pulled. It was like being on race gas… all the time. Suffice it to say I was pretty impressed. Obviously I haven’t logged any data or measured the acceleration at this point but my butt dyno was stoked. What’s crazy is that that there’s still a ton of power left on the table.
