Confirm understanding of lightweight mods

[weederr33]

So the million dollar question is, should I just go down the weight loss list of crank pulley, flywheel, drive shaft? Or should I just go FI instead and call it a day?

FI. But not call it a day, also grippier tires, uprated clutch. If tracked, also better brakes & oil cooler.
NA power gains are expensive. Lightening may mean compromising/loosing lot of daily comfort/usability/features.

It's sarcasm. There's always a compromise no matter which way you go about it.

YEP
FI = Tires,Clutch,Brakes, possibly suspension for the heavier weight on the NOSE. Worse weight distribution. Engine braking or wearing down quicker


Lightness you can decide how far you want to go or compromise but you increase all areas of performance. Acceleration, Braking, Cornering, MPG, Less wear & tear on engine.


Both are going to cost $$$$

SuperTom: not the area of comfort/daily usability features/NVH. I don't want to have lighter car without A/C when stuck in traffic jam during hot summer day. I don't want naked interior and lack of even stock noise dampening especially if paired with very light .. muffler-less track pipe when cruising long distances. I don't want to be stranded with flat tire w/o at least skinny spacesaver donut in boot. I don't want to switch batteries for winter. Car for me is dual use, hence i consider all possible mods in way to not hurt other use for sake of specializing.

FI is simplest way to change weight/power ratio. And if going for light gains kits, one can get by without too big of spendings in way of forged engine internals/better gearbox and other bits in transmission and alikes. NA has it's niche, but gains in it are expensive, made relatively affordable only due rather low max gains limit.

Obviously this thread isn't for you

The answer is, buy a lightweight pulley... and install it on your Exige.

Oh, I'd suggest you just go for an engine swap …..

Reminds me of back-in-the-day, I went into partnership with two other kids and we bought a 1937 Chevrolet pickup truck. Yep, we paid $75 for it and it ran (after we put tires and a battery on/in it).

My partners lived in town and I lived on a farm. One weekend "they" decided to cut the bed off the truck, so it would be lighter and faster in a 1/4 mile drag. Which it did do that.

HOWEVER, I was the one who lived on a farm … and now the damn truck couldn't haul anything ..

Engine swap? Better buy another car.

I also keep a cellphone sized jumper in my glovebox which is less than 2lbs

I think stock battery was like 390cca and 90AH, this batter is like 520cca and 34AH, so i think it should be fine in the winter.

However i have read things about the battery deforming and or catching fire bcs of overcharging? do you know what rate the stock alternator charges at?
really interested in this weight reduction mod, but not if its potentially dangerous or a pain to maintain the batter.

Nope. Engine swap is fair game

hmm haven't heard of issues in a car itself. I think those issue are when you use and outside car charger that pushes a lot of amps. That's why most recommend the shorai charger for it.

Me I'm cheap and use this harborfrieght tender that only pushes .5 amps

Kept mine happy all winter!!

I still don't understand why people are stressing out about changing the battery for the winter. You literally unbolt the + and - terminal, then loosen the tie down, lift battery out. Damn some people are lazy

OK, i was thinking of underdriving the alt to slow down the charge if it was an issue, may still do it anyways to squeeze out that extra 1/2hp

Yes i am really lazy, but you are right i shouldn't let my laziness get the best of me. def on my list of mods to do.

Going to probably copy your battery setup exactly.
