But do they have to limit fuel. Does the advantage of the turbo outweigh more pitstops? I'm afraid races might get boring when drivers will have to conserve their fuel or just lose the race.

It's already the case. You cannot refuel (I think for safety reasons, but not sure), so to get a weight advantage you have to take as little fuel as possible at the beginning of the race. So I don't expect changes. And yes, it happened to some, like Hamilton, to have to drive slower to save fuel. http://www.bbc.com/sport/0/formula1/21917717

Cars going round in circles? I already find that fairly boring.

There's something in the rules about maximum fuel flow rate, which IIRC is 100kg of fuel per hour, with a maximum of 100kg of fuel in the tank, so the trick has been to make these engines as efficient as possible, it's no use having the most powerful engine if if can't reach it's full capability, or can only reach it when it's using the max fuel flow rate as you'll run out having only completed half the lap.

There are so many rules dictating the design of an F1 chassis/engine that I wonder how much faster a "anything goes" car would go.

Yeah! I always thought it would be mint to be able to do whatever you wanted, put a saturn V engine in it you wanted. Would make great telly. Ditto the paralympics - there should be a class where they can pimp up their kit to the max.

This video is an interesting comparison of just how fast F1 cars are:

IIRC some of those GT cars that look like snails compared to F1 cars are "anything goes".

However, here is a truly anything goes car (that has broken the speed barrier on land): http://www.youtube.com/watch?v=LKQ-xj5C2m8

So yeah, an anything goes car will go much faster than an F1 car. But it's going to suck at cornering. We currently don't have anything that can hold such high average speeds as an F1 car can. Not even in any very lightly regulated sport.

For interestingness' sake, modern WRC cars reach speeds of 220kph over gravel.

Top speeds of F1 cars are around 360kph (the Bugatti Veyron can do 430kph), but F1 cares more about cornering speed than top speed.

From Wikipedia:

> The large downforce allows an F1 car to corner at amazing speeds. As an example of the extreme cornering speeds; the Blanchimont and Eau Rouge corners at Spa-Francorchamps are taken flat-out at above 300 km/h (190 mph), whereas the race-spec touring cars can only do so at 150–160 km/h (note that lateral force increases with the square of the speed). A newer and perhaps even more extreme example is the Turn 8 at the Istanbul Park circuit, a 190° relatively tight 4-apex corner, in which the cars maintain speeds between 265 and 285 km/h (165 and 177 mph) (in 2006) and experience between 4.5 g and 5.5 g for 7 seconds—the longest sustained hard cornering in Formula 1.

Adrian Newey (most successful F1 designer in the history of the sport) designed the Red Bull X2010 for the game Gran Turismo based on the concept of building the fastest car possible in an 'anything goes' scenario:

The limit becomes G-forces that a driver can bear, especially over a race distance. They limited it to 6G. For an engine they interestingly picked a 3L V6, where the new F1 formula is a 1.6L V6.
