Since purchasing my Daytona 3 months ago I have not modified the vehicle. It is bone stock! I have my eye set on a nice supercharger and anxiously awaiting the nod from my better half to purchase. During the past three months I have read many reviews on the car and was particularly interested to find that the 0-60 times vary quite extensively. Here is one test from Car and Driver:

C/D TEST RESULTS
ACCELERATION: Seconds
Zero to 30 mph: 2.2
40 mph: 3.1
50 mph: 4.3
60 mph: 5.6
70 mph: 7.1
80 mph: 9.2
90 mph: 11.4
100 mph: 13.9
110 mph: 16.7
120 mph: 20.8
130 mph: 26.0
140 mph: 32.6
Street start, 5-60 mph: 5.8
Top-gear acceleration, 30-50 mph: 2.8
50-70 mph: 3.5
Standing 1/4-mile: 14.2 sec @ 101 mph
Top speed (governor limited): 145 mph

Their indicated 0-60 time is 5.6 sec while other sources range from 5.8-6.5, all of which are drastically different from the numbers I have put up on a stock car. I don't see how 5.6 is possible and I refuse to believe someone actually posted that number on a stock 06' charger R/T regardless of the who the source is (not to mention a 14.2 standing 1/4 mile).

My best time at a 2000rpm launch is 6.8 sec, temp 92 deg @ 2100 feet above sea level. I have tried launching at idle with the same variables only to manage a 7.1 sec 0-60 time. I only weigh 205 and I had a half tank of gas (I always burn 89 octane). I might also mention a power-brake full throttle launch that left a 25 foot black mark and managed a 7.3 sec result.

I am not a drag racer so there could be a technical flaw to my method but we are talking about an automatic. Speaking of the auto tranny, I tried the auto stick method and it did not fair any better times. So...do any of you think I may need a little education on execution or does my car need an adjustment I am not aware of? I have noticed that the inside edge of my exhaust tips are more black than I would expect. Maybe she is running slightly rich. My 02' Mustang had a small amount of black soot inside the exhaust, but nothing like my 06 Charger.

I live in Vegas and I've been getting the same results. It's 2000+ ft up and the temp was around 95 degrees. My best 1/4 time was 14.90. I don't know my 0-60 times. I have a feeling the altitude and air temp effect these cars performance.

 

With a CAI and the SC programmer on 87 octane i ran a 6.4 0-60 and a 8.03 0-70 time. Didn't do anything fancy on launch, just gas and go, not high rpm launch.

This was 87 degrees and 90% humidity.

 

Times will vary depending on the air temp, humidity and air pressure.

Check this link: http://wahiduddin.net/calc/calc_da.htm then run some numbers to see

TB, I plugged your numbers of 92 degrees and 2100' MSL and fudged the dew point and air pressure (56 deg dew pt and 29.92in Hg which is a std day reading). The density altitude is 4851 ft. That's the altitude your engine "thinks" it's at when operating. So you can see why you're getting times in the high sixes/low sevens.

Guys who live on the coasts or at elevations close to sea level and test on a cool, dry day will see significantly better times. That's why when times are reported all the ambient conditions need to be included as well.

TB and moparmike won't see any improvement unless they :

a) move to a lower elevation

or

b) install a supercharger

I fly full size aircraft and density altitude is something that all pilots of piston powered aircraft have to take into account to determine take-off and runway lengths. Hot, humid days at a high elevation airport call for plenty of runway due to lower engine performance.

That's because you live at a place close to or at sea level (20' MSL if I am not mistaken). You already have a 2000' elevation advantage. This makes a big difference.

And don't forget, not only will warm air effect power its also thinner so you need more speed to get the same amount of lift.

As for my times i wasn't bragging just wondering if those are good times. Car and Driver said 5.6 0-60, But noebody on here has come close with stock settings.

Later, Orv

 

Gotta love that cold, dense air.........

Orv, I wasn't thinking you were braggin'. I was just pointing out how different locations and conditions can cause stated times to vary so much. I have a feeling C&D "embelishes" things too much or they're given the most cherry vehicle possible.

3605,

I have a bone stock Daytona with a Jet 2 chip, K&N 63 series CAI, and aftermarket resonator tips. I never play with the tire air pressure or drag racing tricks -- I leave the windows up is my only trick and the A/C is off. I have always ran with 91+ gasoline since new, and now have 10,000 miles on the odometer. I get 25 MPG on the highway and she runs a 14.07 just in "D" and flooring it from a dead stop -- 75 degrees, 800' on the altimeter, light side wind.

I'm not bragging, I'm just letting you know.

Rock on boys, the headers go on this weekend so i'll let you know how much of an improvement i get.

I think with a better launch style i can get into the high 5 range, the car likes to be above 2500 rpm.

We'll see, keep me informed of any tricks you guys come up with.

 

Orv,
Sounds great to me. However, will that lean out the engine too much, or does the air/fuel/O2 sensors just pump more fuel through the injectors?
