Re: BRC 1955 - The Golden Age [BUILD]

I don't want to ruin it for everybody, but I'll just say this: the more weight over the driving wheels there is, the more torque the wheels can take. But how do we increase torque when high end Max power is limited...?

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).

Re: BRC 1955 - The Golden Age [BUILD]

Well I've been at my car for ages! I've changed EVERYTHING so many times to get it just right. Now I'm pretty happy to say I've knocked off a massive four seconds off my time around the Automation track. Off which time, you ask? Well that's my secret haha
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!

@ tycondero

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!

Re: BRC 1955 - The Golden Age [BUILD]

Damn guys, stop waffling on about torque :P you should know better by now that "torque" doesn't matter at all. Power at the wheels does. :) 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]

Coincidentally, I just tested this.

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!

Re: BRC 1955 - The Golden Age [BUILD]

Yeah, my car doesn't like the corners as much as was witnessed in one of the races.

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

Re: BRC 1955 - The Golden Age [BUILD]

I'm obviously keen to know what the balance of the tracks are. Brands Hatch is known to have some technical corners especially with all the elevation changes, and corner speeds are a little lower than average. But Monza has a lot of freaking huge high speed sections but a couple of rather low speed corners too, which is why my peaky little torqueless racer surprisingly didn't go too far behind my rather healthier but slightly heavier car. There seems to be a bit of a sweet spot when it comes to balancing power:weight:drag, and it's a matter of finding it.

Starting to get really pissed at the bugs with saving in Automation. Just lost 4 hours worth of work on an I6 trim I am trying out......

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! :lol:
