Chose your fuel!

[opendriver]

As more and more things got complicated in the GT series, one thing seem to stay the same(at least in GT4 where it became mosy important in enduros) is the fuel. With the modern day abvances in racing fuels they could at least let us chose what kind of fuel we use in the car.

For example,Deisels could run on regular deisel or bio-deisel or something along the lines of that.

On the other hand, there are far more choices for regular gasoline/petrol engines. Just to name a few are different octane ratings(all the way to 116), E85,E10, straight ethanol/alcohol,oxegenated fuels

The next thing is FUEL ADITIVES. This is also a key role in making more power. Propylene Oxide and Methyl Ethyl
Ketone(MEK),Diethylene Ether, and Nitropropane 2
Please keep in mind that all of the fuel additves are highly toxic and extreemly combustable and cancer causing

Just my though on ways to make more power

Okay, but wouldn't you choose the combination that gives you the highest figures all the time? That said, where's the point in having the choice?

How would this be implemented in the game, and why would it matter?

 

[95GTIVR6]

everything causes cancer now-a-days

for all we know, babies could cause cancer

I agree with the Interceptor, however. I believe people would choose the best fuel for the best times.

Although now that I think of it, having fuel selections would allow for more interesting endurances (if there is such a thing). Also, having a fuel pump and engine upgrades to allow cars that wouldnt normally run off ethanol, say...a Fiat Punto, would be kind of neat-o. Or spending 50,000 Cr to convert your V8 Mustang GT into a bio-diesel torque monster.

I think we could leave out the additives though. The PS3 could emit cancer as well.

I'm really not sure this is going to add much to the game. I'm not against the idea but if you are racing you are going to be adding the highest grade your car can handle all the time so I'm not sure the variety will help much, but maybe just slow down gameplay.

 

[Jim Prower]

Hell, for drag events, we could run 89-90% Nitromethane. (which would render your engine useles after one run, but hey, ti was fun whaile it lasted...)

 

[3-Wheel Drive]

I'd like the option to run your car off moonshine, the budget fuel.

 

[GM]

I don't think it'd work picking your fuel, one is enough for me

On the Mustang comment: Don't you think it would have enough tourque if it was given an NA stage 3 tune-up?

On the PS3 cancer issue (sort of): I don't think they would sell the PS3 unless they tested it on lab rats for safety. I once read in a GameInformer, I think, that in Japanese there is a warnong not to open the back of a GameCube or "hazardous fumes will be emitted".
Only in Japanese, and not English. Hmm...

Anyway, Maybe using higher Octane levels in the fuels would be more exciting, like the fact that higher-octane fuels don't burn as long (right? ) so that would make pit strategy more important.

 

[Metar]

Higher Octane fuel burn more efficiently. As a (weird) example, compare the same engine, running normal (say, 98 Octane, which is the standart where I live) Benzine to a N2O-fed engine. The N2O doesn't "propel" the engine like a rocket, but rather burns more efficiently, and therefore generates more power. A high-octane benzine mix is the same, only way weaker. Therefore, I'm pretty sure you're right, and that those fuels burn away faster, but I also think that at the same time, all the valves letting fuel into the engine are still the same, so they let the same amount of fuel in. Again, I'm not sure of nothing.

On Topic, people really would choose the best fuel the car can handle, so it doesn't make much sense to add that option.

However, having differently sized fueltanks would be great - isn't it weird that a Daihatsu Midget has a fuel-tank as big as the ones of the Zonda/Minolta/Some american Musclecar?

Octane is not a measurement of a fuel's burn rate, power potential, energy content, efficiency, or anything like that. It is a measurement of its resistance to premature ignition, i.e. knock, ping, etc. Period. People tend to think that octane = power because high-powered cars use high-octane fuel. They use high-octane fuel because they have high-compression engines, and thus require better pre-detonation protection. It's the higher compression that makes the engine more powerful compared to an engine of the same displacement running lower compression. High compression = more air in the cylinder, which means more fuel. Running high-octane fuel in a car that does not require it adds NOTHING to that car's performance. On the street, you're wasting money running gas that costs more than you need. Run the cheapest gas that doesn't ping; that's the best you can do without adding more air (oxygen) to the intake charge. That's done by pressurized induction, nitrous, and so on. Nitrous doesn't make an engine burn fuel "more efficiently," it allows an engine to burn more fuel by adding oxygen to the intake charge. It's broken down in the heat of combustion, releasing the oxygen to burn more fuel.

On-topic, type of fuel would be irrelevant to me in the game, I would work on the assumption that the correct fuel would be provided for the car. You could say by the team running the car, if you like. What I would like to see, though, is a more realistic relationship between tire wear and fuel capacity, and maybe correct fuel capacities for different cars. In a real race, a team might double-stint the tires, meaning two tanks of gas per tire change. In the games so far, medium race tires usually last less than half a fuel load.

Well, back in the 50's the gas companies used to ad lead to boost octane,just for sales and some other part I cant remember....But a few years later, they realized that all of the lead was clogging up all over the valve covers and engines were braking down and not working corectly. In the 70's the started to produce "unleaded" fuel which had no lead in it.

So when you go to fill up your can, you will see the it says "unleaded" at the pump

When it comes to race engines, you run leaded fuel; that how the achive the high octane numbers like 110 and 114. But if you MIX certian things with it, you can add even more power. Too much and KAABOOOM!!, there goes you engine

First of all, a minor spelling error. It's "choose" not "chose" for the title of this thread. I think this would require re-engineering cars to actually take advantage of everything. I don't see much purpose for this deal unless GT5 was set in a time in which fuel was in scarce supply and had to win every race with some virtually unknown fuel for cars. I don't see this idea flying unless you're probably thinking of what one runner of last year's (or maybe this year's too) 24 Hours at the Nürburgring. One team used some form of bio-diesel for the team's VW New Beetle.

Other than this, it's perfectly fine to stick with super-clean Sony/Polyphony Digital gasoline. Or would you rather pour rocket fuel into your Nissan R92CP and try not to have the car explode and become Kentucky Fried Nissan? I don't really dig this idea. How about the rest of you?

This is off-topic for the thread, and maybe better discussed elsewhere, but:

Lead was in there because it was the cheapest octane booster available, and it was actually a pretty good lubricant for the valves. Valve deposits were more the result of incomplete combustion than the presence of lead.

The reason lead had to come out was the advent of catalytic converters in the exhaust system, as the lead would break down the catalyst and render the device totally ineffective, perhaps even clogged. Thus, race engines run leaded fuel because they are not pollution-controlled.

There was a phase-in period of a 3 or 4 years where low-lead was available, then unleaded in 1974, for the model year 1975 cars, when the converters appeared. This isn't conjecture, I was driving at the time, I'm that old.

Again, octane is NOT a power rating. It is a measurement of the resistance to pre-detonation, which is the gasoline firing due to heat of compression before the spark. This is what causes an engine to ping and knock, the little rattle sound your dad's Crown Vic makes before it downshifts going up a hill. High octane gas does not give a race engine more power, rather a race engine, with it's higher compression ratio, requires fuel with a higher octane rating. An engine with say, a 12.5:1 compression ratio would produce the same power running on 87 octane as on 104, but it wouldn't last very long. The power comes from the high compression squeezing more oxygen into the cylinder.

In a real race, a team might double-stint the tires, meaning two tanks of gas per tire change. In the games so far, medium race tires usually last less than half a fuel load.

I double-stinted an R8 at Le Mans. R1 tires were good for about 14 laps. The remaining two laps were pretty undrivable, but I managed to get it back the pits after lap 16.

As for the fuel issue, I think people are starting to wish for a completely-impossible level of detail in racing games. If you want the game to come out within the next 20 years, you can't have 20 different fuels and expect them to all have different properties. Likewise, we'll never have a clutch/transmission that works like in real life, and we will never have brake fade/wear, or things of that nature. I'll throw some new ones in: if I hit a big bump, I want the strut to start leaking, with the car gradually losing it's balance over the course of the race. When I go off-line, I want marbles to muck up my tires and cause me to lose traction. On bumpy tracks, I want the electrical connections to gradually work their way loose and cut the power steering. Oh wait, I don't want any of those things, BECAUSE IT'S A GAME! Many of the small details that people want would be incredibly tedious and frustrating in a game situation. You want to be able to stall the car? Good luck learning how to launch with a no-feel clutch! Oh, and that clutch is different for each of the 50,000 cars that you want in the game. Uh, have fun?
