Re: Best potential ET on a 125 MPH run? 60= 1.500 44.139 0 to 30 mph=0.795
330= 4.331 82.542 0 to 60 mph=2.491
660= 6.729 102.257 to 100.728 0 to 80 mph=4.092
1000= 8.815 117.627 0 to 100 mph=6.217
1320= 10.600 125.697 to 127.606 0 to 120 mph=9.251
Ft ET MPH
-1 - .213 0.000 = Rollout ET @ 12 inches
0 .000 6.411 = Rollout MPH @ 12 inches
1 0.120 8.975
2 0.185 11.939
3 0.237 13.997
4 0.283 15.650
5 0.324 17.060
6 0.363 18.302
7 0.399 19.421
8 0.433 20.445
9 0.466 21.391
10 0.497 22.275
an MPH of 125 should equal above acceleration rate
with a 1.50 60Ft
330= 4.331 82.542 0 to 60 mph=2.491
660= 6.729 102.257 to 100.728 0 to 80 mph=4.092

Re: Best potential ET on a 125 MPH run? the minimum info i would need to calculate you HP/Torque Curve
1-Total Car Weight with driver
2-Frontal Area in Sq.Ft.
3-Cd (Drag Coefficient)
4-Automatic/Converter or Standard/Clutch
5-Ram-Air HoodScoop or breathing just underhood air (no Ram-Air)
6-Shift RPM
7-Cross RPM
8- 1/4 mile ET and 1/4 mile MPH from time slip
9- Barometric Pressure Inches Hg.
10-Temperature degrees F
11- Relative Humidity % percent
------------------------------------------------
2-Frontal Area in Sq.Ft.
3-Cd (Drag Coefficient)
......if you don't know this Info, then post what
Year Car , Make , and Model
Body Type=Convertible/FastBack/ etc.
-----------------------------------------------------------
For greater accuracy of HP/Torque Curve then also post ;
Post Options ;
1- 60 Ft , 330 Ft , 660Ft, 1000 Ft, 1320Ft ET Times + MPH
2- 60 Ft, 660 FT , 1320 FT + MPH
3- 1320 FT + MPH
4- 60 Ft and 660 Ft
...above 4 options are in descending accuracy order
-------------------------------------------------------------
if you want extreme accuracy calculation of Hp/Torque Curve
then also post as many of the Inputs below ;
1- Transmission Ratios for all gears/speeds
2- Rear gear ratio
3- Rear tire diameter or rollout in inches
4- Rear tire width in inches
5- Rear wheel rim width in inches
6- Launch RPM
7- Converter (Max) Stall RPM
8- Track Elevation in Feet (track's physical height)
9- Density Altitude in feet
10- Wet Bulb Temp deg F
11- Vapor pressure in Inches Hg.
12- Engine Size in cubic inches
13- Compression Ratio
With above Inputs , you can determine such things ,
true real Engine's Torque and HP output !!
you can use this Physics Info to determine if a certain Chassis
or Engine Dyno claims are bogus or misleading .
Determine Torque Converter Lockup/Slip Percentages ,
Torque Converter Multiplication values , and many other things.

Re: Best potential ET on a 125 MPH run? Thanks Max, I dont have all that info right now.
Tom, what was your 60' on that run?
I figure about a 10.6-10.7, more if I could spray out of the hole <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
