Post by Julian BondI have suggested this to people who know about these things. The reply
was that if the limit was 24L, they'd find ways of using the extra and
still pushing the boundaries to the point where electronics were needed
to manage the fuel consumption. We'd be right back where we were, just
with more powerful engines. It wouldn't make the racing any better, just
faster.
And I don't buy it. First off, it pretty much denies what happened in
05-06-07, when 990s dropped from 424 liter to 22 liters and not much
changed, but when the bikes dropped from 990cc to 800cc and from 22
liters to 21 liters, everything seemed to change. Since the bikes had
lower terminal speeds and higher corner speed capability (apparently due
to dynamic engine internals' effect on the bike's physics), the braking
zones were dramatically reduced, the "ideal corner line" allowing
maximum corner speed emphasized, and the ability to accelerate hard out
of corners was reduced, leaving really only one way to get through the
corners, one line, one approach.
But up displacement to 1000cc and that changes, especially if fuel load
is increased. There is a point where fuel becomes the absolute limiting
factor in producing power, and a point where one can't really use any
additional fuel, those boundaries created by the nature of the motors -
four cylinders of some set capacity, maximum rev limitations, etc. I
suspect 21 liters presses the lower boundary because the manufacturers
want it to, it gives them a research and technology boundary to work on,
and because of the elevated revs of the 800s. Increase fuel, reduce
revs, and they no longer are pressing up against a boundary in the same way.
1000s will also allow for a greater variety of cornering approaches, and
riding approaches in general. There was a huge change in the racing
going from '06 to '07, and it wasn't just because of some random
technology leap, it was because of rule changes.
Post by Julian BondIt does seem that whatever gets suggested has unintended consequences.
Rules designed to cut costs actually increase costs. Rules designed to
improve the racing make the racing worse. It's enough to make you think
they should stop trying, throw most of the rules away and go back to the
sort of rulebook we had 30 years ago. 1000cc, 6 gears, 150Kg, the end,
(Honda Wins). The alternative seems to be a spec championship based on
production engines with nothing that actually works in between.
I think the problem is the rules are made by two parties, manufacturers
who want to promote their products and derive some sort of R&D benefit,
but who are in fact competitors and not actually allies, and a
commercial operation (Dorna) which perhaps doesn't actually know that
much about the technical side of racing. It seems like it's the teams
who might be better at making these decisions, since they have to pay
for this stuff, to run it, and to attract sponsorship through doing
that. The 800s were a bad decision which initially got masked some by
the tire fiasco, then by the promotion to the front of the riders who
the series wanted out front, and it was only after a couple years that
people admitted to the fact that the racing sucked. Meanwhile, lots of
rule changes messed things up further.
The rule on engine limitations is a good idea which was overdone, six
motors is simply too few, especially when crashes can take out motors.
The spec tire thing was a bad idea driven by the need to somehow make
sure the most-popular riders didn't end up on anything but the best
tires. The fuel limitation thing kind of snuck up on everyone, I think,
and was driven by the manufacturers and the notion that is was a "green"
concept which might protect racing. Electronics are an evolving problem,
but not quite a revolutionary one, I don't think. The move back to 1000s
is a good idea, but limiting them to allow 800s to remain competitive is
a bad one. And the economic collapse has made it all worse. But at the
core of it all are the crappy-racing 800s; had MotoGP stayed at 990cc, I
really doubt the last 3 1/2 years would look nearly as bad as they have
been.
