Us GPL fans are all very proud of our hunger for realism but yet almost all
of us use one very big cheat when driving the car. There's nobody being a
hotlapper using the clutch, by doing that we can do left foot braking at
almost every part of the track which is totally unrealistic. Even in modern
racing left foot braking isn't a common good, it's used in F1, Rally and on
ovals.

So why do we do it? Because it's possible I presume. I would like Papy to
offer a small patch which turns off the auto clutch and the auto blip so we
could do some real heel and toeing (or inside out as I do it). This would
really make things far more realistic and the times as well probably. The
only problem is that not many people have more that two pedals, but for
those who have it would be great, don't you think?

I would have rearrange my Logi brake pedal and F1 Sim throttle so I could
heel and toe but that won't too much of a problem. I'll start using it from
now on.

Oh and anyone wondering about the status of my little sim it's going very
slowly but I'm right on it. In about 5 years time I'll have a rolling car.

I don't know if this was the case in 1967, but in my FFord it was fine to just
bang up and down the 'box without using the clutch. In fact it was better to do
it that way. Of course, you have to lift off the accelerator when you are
shifting, as you do in GPL (in advanced damage modes).

If I ever drive a 1967 F1 car, I'll let you know if this is possible...

It's been a long time since I read the Four Wheel Drift that came with
GPL, but I think that's exactly what's written there, for both up and
downshifting. Yet watching the movie Grand Prix reveals some wonderful
heel-and-toe practice along with the use of clutch. Go figure.

  From memory - the '67 cars didn't need a clutch to shift gear but many
were so cramped in the footwell that left foot braking wasn't possible.

    I agree with you that it would be a good thing to have the autoclutch
disabled.  However, I think there's only a couple of controlers out there
that have a clutch incorporated right now as you mentioned.  Once there's a
lot of controlers with clutches Then turning the autoclutch off would help
realism.  In my opinion, untill the avalibility of clutch use is programmed
in to many racing sims, I don't think controler manufacturers will make them
a standerd issue.  Then add in the transition where more and more Race Sims
have the clutch avalibility, Controler manufacturers will only have a clutch
expantion pack or add on feature.  Again In my opinion, That transition
period will last at least 4 years with the clutch being standerd issue with
all controlers in the 5th year (2005 or 6).  Then what about ware on the
pots.  Once the pot is worn down, during the peddel travel it'll get to the
point where the clutch will give you a on/off then on/off then on/off effect
making the lever clutch usless.  Unless there's a penilty fo some kind such
as grinding gears and *** brake downs.

    One more issue would be changing gears while at speed.  A button would
work a whole lot quicker then a lever/peddel.  So, to gain an extra 0.1 per
shift with the benifit of over a second per lap... I'd set up a lever for
starts and a button for at speed shifts.  So, a manual clutch system would
vertualy be worthless.  :-(  That's of course if there's no penilties for a
suddon snap of power to the drive train with the on/off button configuration
as mentioned above.

just something to think about,

Sorry Rob, but I don't quite get that, so you don't heel and toe with a non
synchro meshed gearbox?
Doesn't the gearbox make quite some noise?
As far as I know the only way to downshift without a clutch is to match the
revs with road speed and that's done by heel and toeing which isn't very
effective without declutching as we can imagine. Even if you do use the
clutch it's hard to shift down without heel and toeing, hence it's even
smoother to do it in my synchro meshed road car.

Most of us will remember the onboard pictures of Ukyo Katayama's feet during
practise for the Grand Prix of Suzuka. His feet were all over the place,
going down the box.

I never use the clutch on the upshift in a Formula Ford but I have to on the
downshift. Same for the Formula Palmer Audi, I thought. Although I'm not
quite sure because I was having big time problem with the shifts.

I'm 100% sure that GPL models an autoclutch on the downshift (not sure about
the upshift) because you hear a auto rev blip on the downshift, and you
can't blip safely without using the clutch. Without matching the two speeds
you'll hear a lot of strange noises.

I've got one word for you Rob; Dogrings!

<g>

Normally you won't need to clutch when going up through the box, this is no
problem if you do it right (heck you clutch so fast anyway), but there are
two major reasons to start clutching on downshifting:

1) When you get more than the odd 100 HP behind your back, gearboxes start
taking a severe beating
2) When you get more *** grabbing the road, things become *very*
noticeable. If you miss the revs ever so slightly, you'll have ***y lockups
of the rear wheels, upsetting the balance of the car, which may put you in
uncomfortable positions...so get the heel and toe in. Practice in road cars,
and you'll find it is natural in racecars. Smooth is fast, remember :)

Oh, one more thing...you won't have mad mechanics like me running after you
throwing dead dogrings at you :-D

Just about all the controllers out there have buttons......

Well, downshifting from 4th to 3rd at Paddock Hill without the clutch didn't
seem to pose any problem, a corner where a balenced car is critical. The 'box
felt just beautiful to use, I hope I wasn't doing it any damage :)

What about us right foot drivers? I drive an automatic car in 'real
life', so left foot breaking feels very unnatural.

I sometimes use a combination of controllers if I really want to put
the clutch to good use. I use the pedals on my MSFF wheel for breaking
and acceleration, and I assign one of the movements on my MS
Sidewinder Precision Pro (non USB) for the clutch. A digital clutch
feels very unrealistic and so does the clutch control being maintained
by hand, but considering the alternative it works pretty well.

The transmission doesn't know or care whether the clutch is used or not. What
it does care about is not having any torque going through it when you are
changing gears, and having the dogs of the two mating gears going at the same
rpm. You can releave it of torque completely by timing your throttle release.
Matching the speed of the mating gears on downshifts without using the clutch
is dicey. Transmission designs vary, if it feels good, no clunks or jerks, it
probably is.

I've been to Jim Russell too, the international course while it was still at
Donington.
It's possible but it less smooth and it's hard to keep the balance right,
and if you really brake late it almost impossible to do it, no matter how
good your timing is.

When you're really on the limit you'll just have to do it.

Explain me, you drive an automatic car so left foot braking feels unnatural?
I think left foot braking is far easier in an automatic than in a manual
shifter.
With a manual gearbox you constantly have to decide whether not you'll be
left braking, with an automatic box you can do it all the time and there's
no need for heel and toeing. For me it;s the only pro about an automatic.

I find I can't drive GPL with 1 foot, but i also found i can't drive a
US automatic with 2 feet, well i can, but if i had any passengers they'd
be ***in about spilling their coffee when i hit the brakes +).  Its
different when there is actually resistance in the brake pedal.  As I

that long to adjust.
