Ferrari Mailing List: Re: A 458 runs 11.22 @ 132 mph in the 1/4

[Hans E. Hansen (FList]

Oops. Forgot to mention power curve shape.

 

Several years ago, an engineer type crunched the numbers

comparing a ZO6 Corvette to a F355.  Both had about 400hp.

(390, I think, for the Ferrari?).  Anyway, because of the huge

bottom end torque of the Corvette, it jumped ahead of the

Ferrari off the start.  The gap then remained consistent down

the strip.  So the terminal speed was the same for each, but

the Corvette got there a bit quicker.  The guy simulated this

mathematically, but the simulation was done in response to

someone who got beat by a Corvette in just such a manner.

Search the FerrariChat archives back about 10 years or so

ago for the discussion.

2 reasons:

 

1.  The bad start you mention eats time, but doesn't affect

terminal speed.

2.  Weight, aero resistance, and power curve characteristics

of your vehicle.  For example, a light vehicle with a moderate

amount of power (a Lotus 7, for example), will

jump off the start and quickly get to a fairly decent

velocity.  But it then hits an aerodynamic brick wall and

doesn't gain much additional speed.  So it can post a quick

time with low terminal velocity.  Heavier cars with a LOT of

power take a bit of time reaching 60 or so, because of

momentum and wheel spin.  But they have enough power

to not hit that aero brick wall.  They just keep accelerating.

I don’t understand the numbers sometimes. I got a VERY  bad start…heaps of
wheelspin, but terminal speed was only 4mph less than the 458 even though
elapsed time was over 1 second slower.

can someone explain that to me?

No you miss the whole point of the 458...

Anyone can turn those times, its a video game once you have all electronics
and launch control, no skill other than being able to keep the steering
wheel straight is needed (I bet you could use your right foot only to
achieve this 1/4 mile run...)

I ran my Vette out at a local strip last Fall.  Its a 6M, big 305 size rear
tires, 430+hp and lb-ft.  Its a bit of a beast and not great for drag strip
work (and I honestly suck at launches)...  I spent all not starting in the
13.0's and getting into the upper-mid 12 second range but it required a lot
of concentration and work.

There was a guy who showed in a CLS63 AMG.  He ran 12.7 on his first run
12.7 on the second
12.7 on his eighth run...

Guy in a Lexus IS-F ran 12.8's all night long except for 1 run where he ran
a 13.4 (because he wanted to try it without launch control)

To my mind, a waste of time, and honestly the strip is a bit of fun (this
place has $20 run what you brung night)...  There was a guy with a Vette
funny car that ran a 8.2 at 172 mph.  But of course he did that 1 time and
had to go rebuild the thing for his next run...

No question the paddle shifters are faster, but better?  No way.

HAH - is THAT all?
Gimmie that car for a weekend, Enzo - I'll show em.
Yeah,
Just gimmie a weekend - and please, a full tank of gas.
Cheese & crackers all they need is a better driver - -
Yeah - I think I can beat THAT stat.
