well it didnt really happen, or if it did it wasnt documented, and if it was i didnt read it. but here is an interesting post that i found on a formula one tech message board. i'm sure most of you will enjoy this its a good read. theese calculations were done against a 2003 spec f1 car.



This week's fun engineering chore has been to calculate an acceleration rate for a Formula One car with an Indianapolis spec set up.

Car + Driver weight = 1334 lb (min by regs)
Fuel Load = 15 US gallons = 93 lb
Total Weight = 1427 lb
Max Speed = 210 mph
Aerodynamic drag @ maximum speed = 1125 lb
Aerodynamic power @ maximum speed = 630 hp
Transmission power loss @ maximum speed = 200 hp
Tyre power loss @ maximum speed = 80 hp
Drive Tyre diameter = 26.97 in = 2.247 ft
Max downforce @ maximum speed = 3450 lb
Tyre Friction Coefficient, µ = 1.25

Overall gear ratios:

1st = 22.00 : 1, <= 70 mph
2nd = 16.05 : 1, <= 95 mph
3rd = 12.20 : 1, <= 125 mph
4th = 9.84 : 1, <= 155 mph
5th = 8.38 : 1, <= 182 mph
6th = 7.26 : 1, <= 210 mph

Engine performance specifications:

4000 rpm - 90 lb·ft - 69 hp
5000 rpm - 115 lb·ft - 109 hp
6000 rpm - 140 lb·ft - 160 hp
7000 rpm - 165 lb·ft - 220 hp
8000 rpm - 190 lb·ft - 289 hp
9000 rpm - 215 lb·ft - 368 hp
10000 rpm - 240 lb·ft - 457 hp
11000 rpm - 260 lb·ft - 545 hp
12000 rpm - 290 lb·ft - 663 hp
13000 rpm - 310 lb·ft - 767 hp
14000 rpm - 305 lb·ft - 813 hp
15000 rpm - 300 lb·ft - 857 hp
16000 rpm - 285 lb·ft - 868 hp
17000 rpm - 275 lb·ft - 890 hp
18000 rpm - 263 lb·ft - 901 hp
19000 rpm - 251 lb·ft - 908 hp

Through the use of iterative numerical integration, with the assumption that launch control supplies the "perfect" amount of torque to reach the tyres longitudinal traction limit, for the maximum amount of time.... the calculated results.

Note: gear shift time has not been incorporated into the calculation, and still air is assumed for the aerodynamic drag calculations.

Time to reach speed:

0 - 10 mph .... 0.36 sec
0 - 20 mph .... 0.73 sec
0 - 30 mph .... 1.08 sec
0 - 40 mph .... 1.43 sec
0 - 50 mph .... 1.76 sec
0 - 60 mph .... 2.09 sec
0 - 70 mph .... 2.40 sec
0 - 80 mph .... 2.70 sec
0 - 90 mph .... 2.98 sec
0 - 100 mph .... 3.26 sec
0 - 110 mph .... 3.59 sec
0 - 120 mph .... 3.95 sec
0 - 130 mph .... 4.38 sec
0 - 140 mph .... 4.89 sec
0 - 150 mph .... 5.47 sec
0 - 160 mph .... 6.18 sec
0 - 170 mph .... 7.07 sec
0 - 180 mph .... 8.20 sec
0 - 190 mph .... 9.93 sec
0 - 200 mph .... 12.95 sec
0 - 209 mph .... 26.07 sec
maximum speed = 210 mph

Precautionary peculiar disclaimers: Take it as you will, I've no friends in the clobber cleaning business who might have happened to notice dyno plots near an engine test cell in Munich, nor any flies on the wall at a Mannheim area dragstrip that might have been used for private test sessions, nor did I imply any threats to rough up any wheel-chair-bound invalids to obtain their telemetry.

How do those tri-lobal joints hold up with so many repeated applications of maximum torque?

What if there is wind on the track?

How much faster will the car accelerate if the fuel load is dropped to nearly empty?

heh heh Launch control for "Perfect" amount of torque at the limit and can only manage 1.7 60fts?

My car would be pretty damn quick at that weight too.

you do realise that they are on a tire designed with sidewalls specifically NOT to wrinkle for lateral stability.

8 sec 1/4 damn!

now the kicker would be to let it go down the track, make the trun at the end, and run back up the return road and stop.

F1= Simply amazing, simply Genius

theese cars are more than cool. deffinitly.

great information! i have always wondered.. missed out on the usgp twice now maybe next year....

And you do realize that I added an at the end of my reply because I knew that people would quote me and try to correct me. &lt;--- there it is again!

My wife and I will be there .

JL

the f1 cars in gt3 run 8's also.. if i remember right

imagine if they removed "a lil wing" and ran some huge slicks and skinnies in the front.

hopefully so will i! there was a huge difference between watching nhra on tv and in person, the sound and feel was amazing.. i'm hoping f1 is the same way.. especially on the front straight!

considering the cars are not geared for drag racing whatsoever, Thats still pretty substantial. Im sure there is loss in power with the Traction control as well.....

Ugh, I'm sorry I even made that comment. I guess F1 guys are all business and no play, huh?

8 second 1/4? nah i like the 12.9 200mph time on there whooooooo hooooooo, hold on!! lol now imagine driving that speed in florida during love bug season with just a helmet

ModenaTwinTurbo

dont know if u guys cought it but this info is based on last years f1. not this seasons cars. i'd imagine the latest version to be somewhat faster.
