Thanks for the info. I know enough, going to test it later today. Though it is somewhat into the the torque doesn't matter discussion (though sometimes it does).

The moral is if your one of the companies who is withdrawing from competition because your car doesn't seem as fast as the rest, KEEP AT IT! There is always something to change and from the experience I've just had, it's in places you'd lest expect. Chase down those fractions of a second and celebrate each one because they add up!
Also what's great about this particular competition is you don't really know what's going to happen. Between now and when that chequered flag falls.... anything can happen!
Re: BRC 1955 - The Golden Age [BUILD]
Well, actually, that discussion revealed that torque doesn't matter if it's offset by less HP (to oversimplify it I think of it as an area under curve thing, which is kind of the way the game calculates PI). But if HP is the same... That changes a bit!

The power curve is what is important, a wide power band is easier to achieve with a heavier, higher-capacity, lower-revving engine. The extra weight does lead to worse cornering though. So it can be said that you want to get as high a performance index as possible for a given maximum power. That is what performance index was made for in the first place!
My car in the 1945 BRC I used the exhaust to choke down the engine so I could widen the power band and still be under the power to weight ratio. I'm not sure how much it helped as far as my times.
Re: BRC 1955 - The Golden Age [BUILD]
The problem is that the car's fairly excessively heavy, so it suffers somewhat in terms of cornering, and also, fuel consumption and tyre wear. It'll possibly help you a bit on Monza, though if we ever raced on something like Green Hell it will definitely not like the corners!

Its part of the ballancing act in getting the best times.

I have used a 2L 4 cylinder in both the '45 and the '55 race but it depends on what you call "large". I consider a 2L as a mid sized engine (2.4 is large and 1.5 is small) but I consider petrol 4's over 2.5 to be extreme!
