what would happen if you put that blue 100 octane aviation gasoline in a normal car or bike engine?
>>
>>14056696

Knock resistance. But it also contains lead, so it might do something screwey to modern engines not designed for it.
>>
apart from the lead, not much. i feed my car 99 octane so that should not be an issue
>>
Wouldn't lead contaminate your oxygen sensors and catalyst?
>>
>>14056696
The lead will fuck your catalytic converter and lacks upper cylinder lubricant. On a side note, I run 110 AvBlu with a UCL additive in one of my older cars. Not even 100 octane unleaded can keep the knocking under control in the top end when it is tuned for peak power. Actually had to change head gaskets to slightly lower the CR along with running the largest jet that was available for an 850 CFM in the secondary to get it to run under 3500 RPM without any type of knock.


Tl;dr if you don't have cats, try some with a ucl addative.
>>
>>14057224

>lacks upper cylinder lubricant

You have that backwards, its unleaded that lacks lubricant and needs hardened valve seats.
>>
Lead aside, you want to run the worst fuel your car can use without knocking (or causing the knock sensors to retard timing). If your car will run on 89, run it on that. 91, run it on that. Using better fuel than you need will actually cause it to make less power (provided the fuel doesn't have oxygenators / on board oxygen molecules, which is banned in most racing).
>>
>>14057278
No son. AvGas hasn't had UCL for decades to avoid its use in street engines. Some form of UCL is required for cars without hardened valve seats so they do not degrade as quickly. I still wouldn't run AvBlu in any newer car so my point stands.

It will make less power because the higher the octane the lower the btu and slower burn rate.

>>
>>14057692
This is true, but normally you would only go to such a high octane fuel because of the knock resistance on a high compression engine. The same applies to LPG and kerosene (basis of jet fuel iydk)

True, however I didn't read the OP thoroughly.

If we ignore the fact that leaded fuel will fuck your car.

The only bad side effect would be reduced torque, from poor ignition timing.
>>
>>14056696
It'll get fucked by the lead. You're better off just converting to alcohol. E85 is roughly the same cost as regular gasoline in terms of price per mile, but that's subsidized by your taxes. Methanol is about 10% cheaper if you buy it in bulk. Either one will work just as well as 105 octane gasoline, you just have to make your fuel system flow 30% more for ethanol or twice as much for methanol. Plus, you'll get a 5-10% increase in power vs 105 AKI gasoline and they'll keep your exhaust valves sparkly clean.
>>
>>14058415
>roughly same cast as gasoline
Nah, it's more expensive. At least currently.

The average price spread is 15% but it's 40% less efficient.

So price per mile it's around ~15% more expensive.
When oil price goes up the spread will be higher, but the spread needs to be 40% to be equal price per mile.
>>
>>14058482
The stoichiometric ratio for E85 is 9.7:1, compared to 14.7:1 for gasoline. That means you would use 34% more E85, except that E85 is significantly more thermally efficient for various reasons, so the actual difference in fuel usage per mile is around 20-25%. E85 is usually around 15-20% cheaper than regular, so it's a little more expensive than 87 per mile, but typically cheaper than 89 or 91.
>>
>>14058542
Oh, and there's still the part where it's 105 AKI, and because of the higher efficiency, you can make even more power than you could on 105 AKI gasoline.
>>
>>14058542
It's 9:1 not 9.7:1

And how can a fuel be more thermal efficient.. the fuel is creating the heat to be efficiently used by the engine not the other way around.
Ethanol has less potential energy than gasoline. That's why it needs more oxygen. That's why it's 9:1

The efficiency comes from running higher compression. The same reason turbos are more efficient than n/a.

The fuel itself is not more efficient.
>>
>>14058607
Pure ethanol is 9:1. E85 is 9.7 for summer mix and something like 10.1 for winter mix. The increase in efficiency for alcohol has to do with flame front propagation and adiabatic combustion temperature. You get lower combustion temperatures at the same cylinder pressure.
>>
>>14056696
my military fag mate actually put helicopter fuel (from a post-ussr MI-17) in his e46 318ci 1.9 petrol 4cyl. For like 10 minutes the engine was running great, actually much too great until it stopped. Cant remember what exactly broke but his engine was completely fucked, i think he replaced literally everything in the engine head.
>>
>>14058764

That would be similar to putting diesel fuel in a petrol car.
>>
At my old job they hired a pilot every season to fly around in a small Piper scaring off birds, end of the season there were a few 44 Gallon drums of the octane laying around that had to be used up for some reason. The boss let every worker go to the airstrip and fill their cars up with the stuff and far as I know nobody had any issues. Every one had cars from 2008 Mondeos to 80's Camrys.

so do 110 RON additive laden race fuels like Sunoco or VP Racing somehow weasel extra power from engines on their own or is it just because they allow for way higher compression ratios?

its hard to find information about it that isn't manufacturer hype, anecdotal evidence or blatant shilling
>>

Compression ratios, timing adjustment, and so on.
>>
>>14058966
Just the knock resistance, although there are self-oxidizing race fuels out there for crazy power, like nitromethane.

You would have to tune your car to take advantage of the higher octane fuel. I tried it, it works. The gains are pretty low on an all stock car however.

Learn how ratios work dumbass
9:1 is Less air than 14.7:1
>>
>>14058966
No, the knock resistance allows higher compression/better timing before knock.

In fact it contains less energy per litre than pure gasoline and if you kept the tune the same you would see LESS hp on high mixed with octane boosters.

It's not really a problem until you start looking at newer vehicles which would probably be fouled up pretty good due to the lead content.

I thought lead was good for cars and the only reason it was removed was because "muh health and environment"
>>

Not ment for cat converters.
>>
>>14061159
Your car doesn't need a cat converter though, removing it very slightly increases efficiency. Couple that with leaded gas and your car just gained an extra year or two of life.
>>
>>14061155
It's bad if you want top performance. Because lead doesn't help combustion. Otherwise lead clogs the catalytic converter very fast.
>>
>>14061155
Lead used to be good for cars because it helped create better seals when engines weren't as finely machined in production. it prevented knock.

Now that engines have longer lasting gaskets and piston rings lead is not needed. also Catalytic converters were designed on modern cars to deal with different exhaust that comes from unleaded gasoline.

one downside is that unleaded gas has a much shorter shelf life than leaded.
>>
>>14061186
It's the ethanol that ruins gasoline shelf life.

>>14058482

>>
>>14060248
>>14060284
You people are retarded.
Why does it take 40% more fuel to make the same power from ethanol all else equal?
Because it's less efficient. Because it has less potential energy per volume.

Literally the end of discussion.

Altering your engine for use of a naturally higher octane fuel doesn't mean that the higher octane fuel is more efficient.

On a 70 degree day, that's 50f at 4,000ft with 10psia

assuming 10lbs of boost and 75% compressor efficiency
(2^0.283 - 1)*(10 + 273.15)/0.75 = 80c temp change + 10c ambient = 90c intake temp (190f)
