There are a few explanations
for cars that have a slower ET
but yet have a Higher MPH.
One of the most important things
to remember when dragracing is
that the most important thing to
a quick ET is a car that is
quick off the line the first 60
ft. and 330ft. (1)Bad
traction off the line will
ALWAYS give you a higher MPH but
with a slower ET. (2)
Numerically lower rear end
gearing, example(3.08-3.54) will
normally give you a faster MPH
but a slower ET. (3) A car that
is heavy will generally suffer
the most in the first half of
the track hurting ET,but if it
has alot of HP they will often
post some impressive MPH
numbers. An example of this is
Chris Behney's 3.1 280ZX which
ran a 13.2 @ 110MPH and my 2.8
240Z which ran a 13.4 @ 101 MPH.
(4) A car with a lot of high
RPM HP ,but with little low RPM
torque , will accelerate more
slowly off the line (giving a
slower ET) but can have a faster
MPH due to the hard charge at
the top end of the track. (5)
ONE LAST THING TO KEEP IN MIND
when comparing a car that ran
13.8 @ 101 and another that ran
14.2 @102 ,is that the car that
crossed the line at 101MPH in
13.8 sec. could be going 102MPH
in 14.2 sec. if he didnt let off
the gas after crossing the
finish line.
Hope this helps, norm
