),
a British Top Fuel fan asked why American teams go faster than European
teams. It's a good question. The answer is that there are many reasons,
all stemming from them having better tracks and more money. Every run
costs money; the Americans bandy around figures such as $15,000 per run
for Top Fuel. So you take how much money you have per season, and divide
it by that, that's how many runs you can make. If you want to make more
runs with the same amount of money, you have to lower that figure of
$15,000 per run. You have to use the car up less / break less parts and
that may mean running slower. The money in European drag racing is so
small compared to the States that we have substantially less per run
that $15,000. We can't afford to set the cars up as hard as the
Americans do.
Now consider the tracks themselves. Santa Pod is a very good track
and will probably hold much lower ETs than we have seen so far. However
the other European tracks aren't always as good as it, and therefore in
one European season we will get only two or three meetings at a 'good'
track. There is very changeable weather at these meetings, and that
brings different ambient conditions to the motor and different
temperatures to the track surfaces. We visit tracks in four or five
different countries with four or five different motorsport bodies
preparing them. Can you see a problem? We are never able to tune for
increased performance, only for consistency. The Americans also have to
deal with a variety of traction available through the season but the
variation between tracks on the NHRA series is less than the variation
between tracks in the FIA series.
Also, the top American teams are putting in 22 meetings per year plus
test sessions, against our five meetings. They are getting a lot more
run data and experience. They have four qualifiers per meeting, and five
at Indy, whereas we have three. It is often said that the Americans
click off 4s at over 300 on every run. They don't; read the qualifying
and elimination rounds on NHRA online. Obviously, the Americans outright
ETs are much faster than the Europeans, but the average ET. of some
European cars, which is a measure of consistency, is as good as many US
Cars. Andy Carter had an average ET of 5.27 in all elimination rounds of
2001, including one breakage. His average ET. was 5.11 not including the
breakage. He ran within a tenth of the track record on every track he
visited. I am compelled to add though that the performance from both
Bernstein's and Dixon's cars in their 2001 NHRA campaign was just
spectacular in terms of both outright ET and average ET.
Danielle De Porter reported to us when driving Knut's car in Germany
in 1999 that she really had to "drive" on the European tracks.
She said it was a handful compared to just sitting there and letting the
car run down the groove like in the States. That illustrates the poorer
traction we suffer from, which makes it harder for the driver to steer
the car and keep the throttle wide open to keep the fuel and clutch
management working properly. To keep the throttle open against an
average of about 3 Gs longitudinal acceleration with the car shaking and
moving so much that the driver sometimes can't see is not
straightforward! It's harder also for the tuner to prevent the car from
smoking the tires because the tire smoke threshold for a poor track is
so low, and therefore the performance limit is also low.
To illustrate how different European tracks are from each other, Andy
Carter reported that our car was completely different in Alastaro,
Finland, in June 2001 to what it was in Santa Pod, England, two weeks
prior to that, even with a very similar tune up in the car. The last 300
feet in Finland were so loose that he was off the throttle because he
couldn't see where he was going. Believe me, if Andy says he had to get
off it, then he had to get off it. When the traction is good here we can
use it. Andy has ran an 0.854 sixty foot time and Peter Lantz has run an
0.838, but if the track isn't there after 60 feet, no amount of pedaling
or mag retarders will capitalize on those 60 feet times to yield what
they should (4.70 or better).
On the subject of budget, most Europeans have less than 10% of what
American teams run on. I have heard some established Americans laughing
at others trying to start teams with 0.7 million US dollars. The
Americans are the greatest at drag racing but there are a few Europeans
who, if given American budgets, tracks, track time for the driver, and
number of runs to tune from, could give them a run for their money. As
far as tuning goes, many Europeans have tuned fuel cars without data
loggers, and I am one of them at present. Servicing the car is harder
for us because we don't carry the number of spares the Americans do,
like several sets of fresh heads, etc. Americans really just swap parts
and sometimes swap whole motors, whereas we really have to service our
parts, although a few European teams are now going the way of burning a
lot of stuff up.
European tuners and drivers have been to the States but the American
record is held by an American driver and an American tuner. Similarly
American tuners and drivers have been to Europe but the European record
is held by a European driver and a European tuner. In short, Top Fuel is
different in Europe to what it is in America.
