Right around 12:1 could be higher. Could go up to 14:1.

What is the compression ratio of a petrol engine?
It can be anywhere from 8.5 to 1 for a normal car to 13 to 1 or higher for a race engine.
Why compression ratio is greater than 1 in i c engine?
because a 1 to 1 comp ratio would not generateenough power to keep the engine to idle,the higher your ratio the more of a powerful stroke you will have. more power is good.a i c fuel engine will be between 9;1 to 11;1 race motors on hi octane around 14;1
Can you use race fuel in your street car?
Many do, but they have highly modified engines, to use racing fuel in a stock or standard engine is a waste of money, manufactures design most engines to run on regular gas (97 octane), compression determines what octane should be, as a rule of thumb.
What is the weight of a formula 2 car?
Cars must weight at least 650kg, without fuel. This season they also carry 100-150kg of fuel at the race start, but are running on empty by the end of the race.
What is a race tuner for a motorcycle?
The race tuner on a motorcycle is designed to operate the bike at optimal efficiency which under extreme conditions. It adjusts the fuel ratio, engine timing, and spark to match driving conditions.
Why do racecars refuel often during a race?
No ... starting with the 2010 season, cars must start the race with a full load of fuel and are not allowed to refuel during the race.
Can you use 100 octane airplane fuel in your motorcycles or cars?
You sure can. Octane is just an anti-knock rating. Higher compression engines require high Octane fuel to keep from knocking or pinging. This is perfect for high performance engines such as race cars and motorcycles. However in your daily driver it will not do anything but put a strain on your wallet. High Octane does not create more horse power but rather lets you tune your vehicle for more power output by being able to up the compression ratio. So to answer the question, can you use it? Yes. It just won't do anything.
What is the best gas for a car?
If your question refers to, "What is the best gasoline for your car?" your in luck. In a gasoline engine, the piston compresses a fuel and air mixture in the combustion chamber and is then ignited by the spark plug. This reaction of the gasoline/air mixture being burned forces the piston down which is connected to a connecting rod which in turn is connected to a crank. This turns the gasoline air mixture into rotating mechanical movement used to drive our vehicles. Engines are built with a specific compression ratio in mind. This compression ratio is the volume in the cylinder when the piston is furthest in the down stroke, to the valume the piston compresses in the "quinch area". For instance, if you have a 50cc engine and the complete volume is 50cc, and your quinch area volume is 5cc with the piston top dead center, your compression ratio is 10:1. Gasoline is rated in Octane. Standard gasoline at the pump is 85 octane and is good for engines with a compression ratio not to exceed 9.5:1. (This is an educated guess) Octane refers to the ability of the gasoline to be compressed without being ignited by the "heat of compression" Remember, the higher the compression, the more horsepower. If you try to run a high compression engine like many motorcycle engines(11.5:1) on 85 Octane you may notice a pinging noise comming from it. This is the low octane fuel being preignited, and can actually cause damage to the piston and valves. The best gasoline to run in your vehicle is the gas your owners manual tells you to run. Running premium or super unleaded in a vehicle that's compression is only 8.5:1 is pointless. Its no cleaner, it just cost more. Alcohol or Methanol (Race fuel) has an ability to withstand high compression, but generally twice as much alcohol to gasoline is needed to go the same distance. You can certainly get a lot of horsepower out of these fuels but the draw back is having to use twice as much than gasoline. Same goes for Nitro Methanol. In Drag race engines with a blower, the compression ratio is built to be right around 5:1. THis is so that when the engine is running, the blower can push tons of methanol or nitromethanol into the combusiton chamber essentially raising the compression ratio to 12:1 sometimes 16:1 only because of the amout of fuel and air the blower is forcing into the cylinders. This all results in HUGE HORSEPOWER. Diesel is a fuel that has to be injected and is ignited by the "Heat of Compresstion" Generally diesel engines run 20:1 or higher compression ratios depending on the appliction. So really, you have to answer your own question. What is my application? Only then will you know what the best gas to use is.
How do you put together a scooter with ihc compression?
You put the compression on the fork with out a top race for the headset. Then you put on the compression cap. Next you put in the compression bolt and tighten it. Now you're good to go!
What cars use octane 95?
Very high compression race engines.
How much fuel capacity of F1 cars?
180 litres, I believe, however all cars are under-fueled for the race so the driver must save fuel to make it to the end of the race, but this also makes the car lighter in the early stages of the race.
How much fuel can a race car hold?
28 gallons of fuel
