Created the gear chart after a few people asked. If you'd like to add to the chart I'd appreciate it.

I'd be a little cautious about posting anecdotal evidence/reviews like that. There are so many variables and gaugees/senders/gears/etc. that you may see huge variances. Just a thought, trying to be constructive.12sec67 said:it would be helpfull to have people put there cruise rpm @ 65mph
jst6 said:Tire, Transmission & Gear Combo, and 1/4 mile calculators in MS Excel
I made this using the standard functions for quarter mile estimates, outside tire diameters, and transmission and gear ratios to find final drive and cruising speed for any combonation you like. if you want to save the file just right click and save as or open it in IE as long as you have excel it will work fine. here is a screen shot:

all light grey fields are editable. the rest are locked to keep the integrity of the formulas. the formulas are posted at the top of each sheet.
Agreed! Although the simple math calculations are essentialy theortical (many variables cannot be inserted in Excel by a novice like me...air temperature and tire flex for example) I prefer the math over 'some guy said his does this' type of stuff. As mentioned the factory gauges are horribly inaccurate and there's variances even in the high dollar aftermarket ones.jst6 said:its not data, its not subjective anecdotal information. It is cold hard mathematical CALCULATOR. It is good for any year, make, or model. All you need is the transmission ratios, gear ratio, and tire size.
Matt it will be done this evening bud, when I get home.... I have had a few people fuss at me for that oversight already...MustangMatt1966 said:can you add 3.80 gears please.
