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

[750hp]

Picking up 31mph in the second half of the track is impressive!!!

[KenC]

The ferrari was fast and consistent, and as said driver doesn't make much differences with that car, especially since there running the clock and reaction time doesn't count. The track that day was in bad shape, 40 degrees and hadn't had a major competition in some time and the spray rig was down. So we didn't see the best of Cobra's. Under better track conditions the one 12 sec Cobra could have broken into 11 easilly and he wasn't even able to really get any good speed shifting off. His car was also down about 150 or so hp/Q compared to proposed Kirkham. So two things the Cobra will have to do, get off the line as cleanly as possible, which will take tons of practices to not smoke the tires and bring as many ponies as he can on the top end. I had first hand knowledge of the smokin'm them off the line that day.

That Ferrari did not give up the whole way and the traction control appeared to be very well engineered !!!! Horespower you can't get to the track is just smack talk!!!!

The fairier bet would be to have the Ferrari run without traction/launch control. Then we got a race !!!!!

Tommy 10's with a harder launch. Thanks for the numbers. I have seen lots of drag cars run upper 9's at that mph. Mark

[Don]

Tom......full automatic mode or are you manually controlling the shift points or ....... ?

[KenC]

Tommy thanks for renting the track and letting some of us low income folks try our talent. I had to leave to go to work so only got one pass in my blown truck and as you saw smoked the tires all the way through second gear

Sounded and looked good doing it though

Remember if you ever need a gargage to store your second Ferrari in, I volunteer. I wash it and wax it and even take it out do what we call and Italian Tune Up, ie run the **** out of it to blown out the carbon

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!
