Continuation of Thread: Drag race - Kirkham 65 side-oiler vs Ferrari 458 Italia

[Don]

I have mentioned the Road & Track 1/4 mile test of the 458: 11.0 @ 128.5. From R & T:

Acceleration

" The single most telling quantitative metric we use that displays effective power a car makes (or how well it uses that power) is acceleration testing. We report standing-start times to speeds of up to 130 mph and time-to-distance figures of 100 ft., 500 ft., 900 ft., and 1320 ft. (a quarter mile).

Although we record the ambient conditions at the time of testing, we do not adjust our figures to compensate for temperature, humidity, elevation and the like. We do, however, still follow the NHRA drag-strip procedure of a 1-ft. rollout, where the time it takes a car to travel 1 ft. is subtracted from the raw times (this ranges from 0.2 second to as much as 0.4 sec. depending on the amount of wheelspin a vehicle sees at launch). Why this 1-ft. distance? At NHRA drag strips, timing doesn't begin until the vehicle has traveled roughly one foot.

Many high-performance cars nowadays come with various built-in assist systems (like launch control) which help a driver achieve repeatable maximum acceleration from a standstill, and no-lift shifting, which allows you to maintain wide-open throttle while shifting a traditional manual gearbox. While we readily employ every helpful electronic aid a car offers, we test just about every configuration possible to achieve the quickest result. This often means turning off traction/stability control to prevent the computer from bogging the engine, and sometimes even ignoring certain "launch control" systems altogether if our right foot can do better.

The optimum amount of wheelspin we get at launch depends heavily on a car's engine characteristics as well as the number of driven wheels. Some cars that make gobs of torque down low benefit from little to no wheelspin (a Dodge Viper, for instance), while others that like to be revved to the stratosphere require copious amounts to stay within their powerband (think Honda S2000). This is typically a trial-and-error process that gets shorter once you begin to figure out what types of cars respond best to certain methods.

The test notes in every road test data panel typically outline the procedure we used to get the best performance, and includes launch rpm, the amount of clutch finesse, and optimal shift point if it occurs before redline. "

You have to take tests of Ferrari's by the media with a grain of salt:

I'll say I'm sorry in advance... It has been a while since I have looked at the forum, but I came across this thread (and the other related one) and between them there are several hundred posts. So it is a little confusing. But.. I am wondering when the race is going to be? And are the results going to be posted here?

3/8/2011, and yes.

late start
lousy start
engine missing down the track
12.3 ET?

go ahead and subtract 1.5 seconds off that pathetic example of a "practice run"

He is running for ET...not off the tree.
Engine runs like a sewing machine on steriods.
It's 11.3...not 12.3.

Where are your runs???

[Machiavelli]

look at the cobra run, not the ferrari

look at your post. it is the Ferrari run. Do you have a video of your car running?

[Machiavelli]

that is the default 1st vid from the link, I copied it from the actaul cobra run on the earlier post - apparently it goes back to the default 1st vid ...

try this ...
http://mdman352.smugmug.com/Cars/Sma...89314441_HhT5t

what on earth does a video of my car running have to do with any of this?
nada, nada a damn thing! where's the video of your car running

[Hotfingrs]

Nothing is more annoying than someone with no profile, and no car, calling someone else's pathetic....

[Excaliber]

The Cobra in the video is NOT the Cobra running in the upcoming race. So, whats the point of the post at all? nada, nada, nada. It could be anybody's Cobra. 12.2-12.3 is a pretty typcial ET for a decent Cobra, by the way, fairly common time.

[Machiavelli]

that IS the point, glad you finally caught up!
"The Cobra in the video is NOT the Cobra running in the upcoming race" duh!

yet, you guys think a 12.3 is what the ferrari has to beat, what nonsense.
particularly in that case, lame start and miss firing down the strip, too funny

[RodKnock]

The open cockpit question hasn't been answered emphatically, so there may not be any "runs."

Heck, I wish I could knock off a 12.3 run. I'd be ecstatic breaking into the 14's.

[Mdman352]

the car running 12.3 was not missing but hitting the rev limiter.

here is my abbreviated run

Where is your run???
Do you even own a Cobra??? or are you a keyboard driver??

[Excaliber]

Machiavelli says,

...you guys think a 12.3 is what the ferrari has to beat,

I don't know who the "you guys" are you think your referring to. There was never any doubt that kind of TYPICAL on STREET TIRES ET would be anywhere near fast enough.

You do seem very confused by all this. I suggest you read in it's entirety all the posts on both threads and try to come up to speed before posting any more of this miss leading drival on a subject you clearly don't understand.

Mdman, it's a "fast" run, if that's your car. There are lot's of Cobra's that can turn that kind of ET, lot's that can't. To get into the low 11's, you GOT to have some kind of slicks or serious traction. Horse power is not the problem here.

Rodknock is sand bagging. You could do 14's with one arm tied behind your back!

"After too many passes to count the smackdown started.....(note the dark coloration at the rear of Blitz's pants. In addition, late in the video, he is seen rumaging through the trash can for time slips to destroy)."

"More smackdown with Blitz showing his underbelly....."

"I don't care what tire Blitz uses, bet the Ferrari to take all 3."

So, I guess this "Smackdown in Maryland" is the smackdown of the Madman eh? Can't be Blitz, he wasn't there and is still the unknown.
But now I get it, "12.2-12.3 is a pretty typcial ET for a decent Cobra, by the way, fairly common time." - that's what you guys run on a good day.

But Blitz with his slicks? There are guys out there that sandbag suckers for a living, and the 1/4 mile venu is as good as any for that.

Now here is a guy that defines "troll".

But then again English might not be his first language so his comprehension of what he reads is severally lacking.

[Machiavelli]

One last thought, let's not call this a drag race, let's call it the "Betty Sue 440".

No christmas tree start, but we might go close together for the excitement factor.
I'll give you .2 but don't mess with the tires.

What other conditions are out there that I missed? Is this how real men settle a "mine is bigger than yours" bet? I don't think so. Tom "The Mongoose" McEwen would not endorce this race, not hardly. He would say - put your wives in the minivans and let them settle it with a race to Safeway.

Why did you re - enter this thread ?? You should be booted ... dark coloration dump a load ? this is a place for adults ? do want some cheese ?
Sad

I believe Blitz was in Maryland at the dragstrip, and is in the videos to which you referred (just not there with his Kirkham).
