When you are running a long race you start w/ lots of fuel on board.  This
additional weight slows acceleration and your top speed at the end of a
straight.  If you use a gear ratio designed for 4 gallons with a full tank,
you will shift later and never get into the power band in top gear.  As far
as how the additional weight affects handling because of weight
distribution, I don't know, maybe stiffer roll bars?  I set my gears up so
that the gear ratio is just right after I have used half of my fuel.  So
your setup should depend on how many laps you run.

I read somewhere that I should be using different setups for qualifying and
race.

Why?

I downloaded some guy's hotlap setup for the Lotus, and put in 500+ laps at
Monza. Now I'm doing 1.28.xx consistently, as opposed to 1.30++ with default
setups.

Why should I alter a setup designed for hotlaps that has proven itself to be
a success, just because I'm going to race?

Go outside your house. Run as fast as possible till you drop. Now run at a
slower pace for a longer time. There is a difference. A typical hotlap setup is
way too squirrley for comfortable running over a long race, and a race setup is
just slower than a hotlap setup. Hotlap setups are usually a bit stiffer in the
suspension, lower gears and less gas. Check this out for setup info.

        You don't necessarily need a "Qualifying" setup.  While driving in a
race, you have to be able to conserve the tires by way of Not over
heating them.  And, With a Qualifying setup, you can have a car that's
loose as hell.  With this setup you'll be quite a bit faster then your
normal for at least two laps.  After that, the car would become almost
uncontrollable.  With a "Race" setup, you need to be able to safely
drive many different lines on the track while in traffic.  This means
setting it up quite differently then your Qualifying setup.

        Unfortunately, most practice sessions for Pickup races are just a bit
shorter then the race it self.  So, for those races, you can use any
setup.  For league races it's not much different, but your finishing
position is a whole lot more dependent on your starting position.  Now
if you were in a league that had 30 minutes or less for qualifying for a
full length GP race, then a separate Qualifying and Race setup is
needed.

        To sum it up.. a Qualifying setup can be made to run one line and there
for make quick laps.  A Race setup must be more conservative to allow
for traffic.

At Monza the difference between a hotlap and a race setup might no be
that big. But if you try some hotlap setup for example in a long race
at  Zandvoort I'm sure you will heat up the tyres very quickly and
then you'll be going slooooow or crash out.

I use my hotlap setups for online practice sessions too but for the
race I always use at least a little different setup. Naturally, more
fuel. :) Usually a longer 5th gear, and maybe some other gears too. I
also use less tyre pressure. Those are the most usual changes, at some
tracks it's also good to put more ride height and maybe do some other
small changes too.

Why longer gears with more gas, i.e. more weight?

Normally, I would believe that higher weight would call for lower gearing,
because i takes longer time to reach top speed. Am I wrong?

I did change the gearing in the hotlap setup I downloaded. I found that the
gears was too short. Longer 3, 4 and 5 gave me slighly improved overall lap
times. Or maybe it was more seat time that caused the improvement?

BTW: when do you veterans shift gears? At the torque peak, or the BHP peak?
I usually shift at the torque peak.

I haven't got time for running round my house. Espacially not many laps in a
slow pace. Too busy playing GPL :-)

Just joking. I got your point.

Nice link. I've printed out everything. Now it is time for reading.

Since I'm not much of a setup mechanic, I take the easy way out.  I just fill
up the qualify setup for a full race.  In ICR, I used to just put enough fuel
in my race setup to make the qual. laps...
Not perfect, but until I find some setup 'skill'...<g>

Jon,

     Your advice only works if your running Grand Prix races. For the
average 9-17 lap inter short race there isn't that much fuel to make a
difference.  And the longest pro race I've been in is only 27 laps,so
changing the gearing really isn't important. What's important is stiffening
up the suspension as much as possible for 1or 2 all out laps. You really
need a softer setup for the actual race since you have to deal with other
cars making you either change your line or braking and turn in points.

Depends on driving styles.  In shorter races i will basically run a
qualifying setup with the tire temps knocked down a pound.  Similar
gearing.  But for the longer races where I have to have a car that will
still be running at the end I do up some of the gears a notch or 2.
