You left out a lot. You also need bolt-ons and flex fuel kit. Bolt on's include bigger turbo, bigger fuel pump, etc. Not that simple
On a lot of cars you don't need anything traditionally considered bolt-ons to take significant advantage of E. Just a tune and an Ethanol sensor. Or only a tune if you're very fastidious about making sure your E% is exactly right.
Now yes if you want to make REALLY big power then you start to need bolt-ons. But you can usually get pretty solid gains with all stock hardware just by changing the map that accounts for the extra fuel.

you ever see the new Subaru WRX at the track when you go?
Don’t seem them often but actually saw one last track event. Idk the level of the driver but it wasn’t turning quick lap times. Respectable but not quick.

if someone drives that much, they like do 'ok' or are retired and can easily afford that increment.
it's only an 'issue' to the struggling or a ridiculous 'obsession' to the well off. i think it comes from when most people didn't have much, like their first car in college, and gas prices mattered. for most here? likely materially makes zero difference. waiting in lines at costco or only getting gas on tuesdays to save half the price of a cup of coffee at starbucks seems a little silly to me. but certainly harmless.
i didn't know anything about e85. looked up this and apparently it's for flex fuel vehicles only... why on earth would he put it in his tuned s4? he thought he might get .1 seconds off his 0-60?
and while we're talking about fuel economy, i note that e85 is worse than gas.
Remember those racing videos and builds mentioned before that you don’t watch, E85 is usually a topic and often used.

You can run E20-E25 in a stock Type R. Just like you can run it in a stock vehicle that of course is rated to run E85. Along with increase in power, your vehicle will run cooler with E85…intake temps. I’ve ran 2-3 track days without running E85 and can definitely tell a difference. There’s a very noticeable difference running 20% E vs running 40-45% E especially on the track.
Also E85 is cheaper than regular gas. Before I went to the track I paid $1.99/gallon for E85 and paid $3.07/gallon for 93. I usually take 15 gallons of E85 with me because some places don’t have E85 and plus it’s convenient and cheaper having your own gas at the track instead of using gas pumps at the tracks. Example 93 at the track was $6/gallon.
E85 is worse for fuel economy. To make economic sense, it needs to cost less than 2/3 of the price of regular unleaded to save money.
Where E85 does shine, however, is in performance. With the right tune you can get a lot more power out of E85 than 93 octane.
Can't just measure the comparison between most pump-gas (E10 or so) and E85 in fuel-mileage and price alone. Ethanol is generally safer, with a lower flash-point than gas....which is why most auto-racing converted to it decades ago. Ethanol makes the engine run cleaner, which means less maintenance and carbon build-up inside the engine. And its higher octane allows more spark-advance, allowing more potential power...without the added risk of detonation and spark-knock. It also is made from locally-grown corn int eh Midwest, instead of often expensive crude oil, and the corn that it is made from is not the high-quality corn that humans eat.....it is barely fit for farm animals.
Of course, the main drawback with ethanol is fuel mileage..as you note, all else equal, expect a BIG drop in mileage. A gallon of ethanol has only about 60% of the potential energy as a gallon of typical gasoline.
I'm not "obsessed with gas prices" its just an interesting conversation and the prices are there glowing at you per gallon as you drive down the street. My life is going to go on the same if gas is $3 or $7.
If gas hits $7, that will be the least of our worries.
Instead of the insane $60 it cost to feed three from KFC, it'll be over $100. If we think things are expensive now, just wait.
We don't want semis that get 4-5MPG bringing us our food paying 7 bucks a gallon for diesel.
My life would change, I would no longer drive anywhere except the necessary places.
I would seriously pity average Americans who have no choice.
gas is very unlikely to hit $7 unless there's a major war involving major oil producer(s).
and the u.s. is the world's largest producer now... while we don't use it all domestically, in theory we could. the u.s.' interest in the middle east is waning. the geopolitics are encouraging and concerning at the same time. because even if the u.s. doesn't need their oil, if the supply is destabilized it will affect others (including allies) around the world.
Of course nobody wants gas to go to $7, but $7 a gallon gas means a tank of gas would cost me $140 vs $80. $60 a week isn't going to make a difference in my life. In the Pacifica I buy a tank of gas about every 3 months, so thats another $50 every 3 months. There are many many other people though for whom it would be a big issue, and like you said there would be other issues associated with that.
$7 gas would not make KFC $100 lol, and it doesn't cost $60 to feed 3 people from KFC now, try $35.
BMW X1 with broken RH tail light lens. Hard to see on camera but the LED is actually white they rely on the lens for red I find this very odd. Especially since RED LEDs are the most common colour and well proven.

It all begins and ends with energy. Gas goes up so does everything else. Truckers/companies that are paying $2 a mile to bring us our crap is what makes everything expensive, a big big part of it at least.
Thanks for calling me a liar again lol, I spent like $58 for three of us at KFC to go the other week.
