Depends on the corner: what counts (also depending on the bit
of track following the corner) is exit speed. Run, don't walk
to amazon.com and order your copy of "Going Faster" by a
certain Mr. Lopez. It's the best book I've read so far on
driving technique (funny as hell in parts, too ;-) and it
gained me at least a second on all the non-nuerburging tracks.

Do not stomp the gas. Transition from neutral to full throttle
should take one to two seconds at least, again depending on the
corner.

Cheers,

Uwe

better yet.. read the gp3 manual and get your head around the friction
circle (F1 racing also did an article on this a year or two ago)... once you
understand that, you really get a feel for the relationship between
throttle/brake and steering input.. and getting the most from the cars grip.

Yeah, I read that on the plane to Laguna Seca last year.  Very interesting and
cool to read, but it hasn't helped yet.

Two seconds?  That's an ETERNITY...  Meanwhile, everyone else is rocketing
away...

Well, I'm might be rocketting away from you, but I take 1-2
secs to go from neutral to full, so it must work ;-)

Again, this makes no sense.  How can you take LONGER to get back on the gas,
but pull away faster?!?  Ugh, I'm gettin' a headache...<g>

I think it's a mistake to think Uwe gets on the gas "later". On the
contrary, if one "jumps" on the gas one has to "get on it" later. I.e. 10-1
Uwe gets on the gas sooner than you and, because he applies it smoother,
doesn't get wheelspin and is moving a couple mph faster when he gets to full
throttle (which might be at the same time you do or even sooner depending on
the layout of the turn), then continues to build on that advantage throuh
the exit and down the next straight.

Also, he could be coming onto the throttle later, but that enables him
to carry much more speed through the corner, and that's exactly what
works best in some corners. The problem is, you sacrifice much more
lateral grip than you gain in longitudinal acceleration when you go to
full throttle since only two wheels are driven and the fronts must carry
very little lateral force when the rears are at full power in a low
gear.

It's probably the higher cornering speed.  People can go faster in the turns
faster than I can' even if I'm right on their bumper(meaning driving the same
line).  I've had drivers lap me in league races, and they checked out before I
could even observe their driving enough to help me.

You know, if that is the case, it sounds to me like an understeering
setup. Perhaps you should try experimenting with something that is
fairly neutral in the middle of the turn and sacrifice it for some
oversteer on the exit, although one can be surprised how well presumably
oversteering setups can behave on exits if one applies the throttle
smoothly!

I'd start with opening the diff on the coast side.

Unfortunately, I don't have any setup skill.  You might as well have posted
your suggestion in Chinese - I would have understood it about the same... :)
Are Alison's settings usually understeering?

Nearer is only that - nearer.  If I dropped .01 second, that would be nearer.
It wouldn't really help me, though<G>
Still at about +25 seconds - I have a long way to go...

Hey Eldred,

Alison's settings seem to be actually very nice to drive (esp. her
Ferrari ones), so perhaps it's not an understeering setup. But, just to
see, what is the differential setting? I find that for me 1 clutch with
a 60/60 works about the best in a Ferrari, as the car doesn't resist
turning in that way.
