Data Sheet for Gearing at most tracks

[JeffW]

Could someone please provide me with the link to the thread where someone once posted gear ratios for just about every track on the continent? I saw it once I'm sure, think I printed it, but can't find it if I did.

Thanks for any help

Thanks for that. From the few I am familiar with it certainly gets you in the ball park.

This is for FC and perhaps F2000 correct?

[JeffW]

Yes that's correct Reddog - Pinto motor, and a Mk9 box using a 10:31 diff.

I was aware that this was the FC thread .... but wasn't completly sure ... so thanks

Is there a 9/31 conversion, or a list for 1600 FF cars?

With the new tracks that have been brought on line, the sheet needs to be updated. If and when that happens it would be nice if a date was added as a reference as to what revision it is.

Hello Rick,
I'm trying to use your gear chart to help me decide on what Autox ratios I should run. How can I add some fixed ratios like 13/37 and 16/25, into the 1st gear category? Also how to add all of the 1st gear options (except for the 13/37 and 16/25 fixed gears) into the 2nd gear category (it was suggested to me to run a 1st gear ratio as a 2nd for getting a better ratio in Autocross)

Thanks for the help,

I also found that most of the setups I saw there were (for me) usually under-geared by a couple of teeth, especially in the lower gears. Top gears were usually good within 1 tooth, although some were also too low. I'm guessing that I never felt right braking down to the speeds those gears were correct for. I always want to carry more speed into the corners than those gears allow.

It may be that some of those gear choices are so old that the tires of that era did not allow that much speed on corner entry.

This is a 2 year old post that I just came across. I know most of this is out of date but the Excel sheet Rick provided above my comment is very helpful with trying to gear for Autocross, I just can't figure out how to add more gears into the columns.

I just looked at that - it's sure not obvious, although I could edit the existing entries within column AE to get whatever gear I wanted.

Unfamiliar with autocross but wouldn't first gear be the same for each course, "Get the eff out of Dodge from a standstill so to speak" (Dodge is in west Kansas) ...... and, you are going to say, "No, sometimes I want to limit going to second in places ................... .....

Sounds good, Numb below!!! are u really 14 or maybe that's 2014!!! little slow on the roman numerals, used to sign my school papers, Odie LXIX in kind of a symbol form

In order to use a lower range of gears needed for autox, it was suggested to use a fixed 1st, a 1st gear in the second position, and a low second as 3rd. So essentially I'd just be using 3rd gear because its a 2nd gear position. The fixed first and 1st as second would help the car to get up to speed while always in the power and of a pinto motor. Am i making any sense?

This might help you estimate the speed range to expect in autocross.

Wow, exactly the gears I was thinking about running! Thanks Neil!
