!!!Revised Simulator Runs of 3.27 vs 4.10s!!!
Read all information please.
Now I can't simulate every driving condition out there for you. We all drive on roads which are comprized of Asphault or concrete and dragstrips with different levels of traction compound. So I have to simulate data that will work for both people who cruise to hard core drag racers. It is very hard for me to argue anything with so many variable. So I've come together with a driving condition that hopefully will meet everones criteria. Your driving along on new fresh asphault it happend that today is a SAE condtioned day and that means the weather condtions meet an exact spec (which you will see below). This condtion is extremely unlike to happen and I can simulate any condition but i needed to pick a standard. You Stop at a light and the light goes green you give it all you have. So I will run the data for that kind of driving. A quarter mile is to be the simulation.
Spec were pulled from: http://www.mach1registry.com/images/2004mustangs.pdf
Driving conditions:
(SAE standard condtions)
-29.6 MG inchs <- Atmosphere Pressure
-77 Degs F <-Out side air temp
-49 Dew point <- The dew point (Moisture)
-No wind <- NO wind at all
Driver:
Average driver who has been to the track a few times to racer.
-3000 Rpm launch <- The launch rpm.
-5700 Rpm shifts <- Rev 1st to 5700 shift/2ed 5700 shift/3rd 5700 Shift/4th 5700 Shift/5th
-.4 sec shift times <-The time it take for the driver to shift gears
(This is typical, as .2 is like a shiftkit on an auto)
-And rpm matching <- Matching the Engine Rpm to the transmission rpm before releasing the
clutch (Running 100% without lifting is too dangerous to the tranny and
wont be simulated even know It will increase performance)
Engine Infromation:
!!!Engine was now simulated fully on 91 octain on an SAE day!!!
!!!This is a full curve instead of the computer est of the full power curve as before
-Cubic Inches 280.1
-255hp @ 5250 @ fly wheel <-- If I change to STD condtions of 29.92 and 59F 260hp is
avaliable
-299 lbs torque @ 4000 @ fly wheel <-SAE not STD
Clutch Information:
-Diameter: 10.5 Inches
-Force: 1600lbs <-est. (But close)
-Singe metal disk
Transmission:
!!!Corrected data!!!
-With the T-3650 (3.35)(1.99)(1.32)(1)(.68)
-97% eff which is the average effeicny of a manual (Spec sheet)
Rearend:
-LSD (50%)<-- Amount of slip in the rearend
-3.27 and 4.10 gears
Tires:
-8.8 x 24.9 Tires @ 34 lbs (weight) each <-Radial style tire
-80% tractions (This simulates the level of traction on the road 80% = Tire on good asphualt, 95% = Drag strip with good Traction compound)
Car Body information:
!!!Corrected data!!!
-The car weighted 3642lbs = (3347 dry + 96lbs of gas + 200lbs Driver)
-.42 drag coef <- Amount of drag
-57% front weight and 43% rear weight - Weight distribution
-101.3 In wheelbase
-60.1 Inch rear track
-20 Inch center of gravity
-Suspension stiffness of a modern car
Strip Simlation
-Good Asphault
-Distance of 1320 feet
-A 10 inch rollout.
3.27s
4.10s
Keep In mind this is not at a drag strip and the soul purpose is to see the difference in 3.27 vs 4.10s.
