The Perpetual "What Gearing Do I Run at This Track?" Thread

Any insights on the gearing for the new configuration of Pitt Race? 22" Hoosier rears

[DaveW]

I've been running 19/32, 21/30, 23/28, 25/27 with 70.5" circumference (22.4" diameter) radial rear Hoosiers and a 10/31.

Any gear ratio recommendations for an FC with 10:31 R&P and Pinto engine running counter clockwise at MSR Houston. Well, while were at it, Eagles Canyon ratios would also be welcome. Thanks

[Bob Coury]

Looking for the subject gears on AR diameter tires please. Can make due with Hoosier data.

Thanks
Bob

Anyone with Circuit of the Americas baseline gearing insight for a Pinto powered '88 Reynard FC?

[DaveW]

Anyone have a gear setup for Barber?

Anyone have gear advise for MSR Cresson?

[Speed Sport Engineering]

Anyone have a known decent gear setup for Gingerman? I have a 13:36 R&P, but I can convert from 10:31. I'm not sure if the suggestions in the baseline database are for the newer long course.

Was thinking to run PBIR one last time....... before it maybe becomes a WalMart distribution center?
There was never a published reply back in 2010 to Skip when he asked about Palm Beach gears and no update to the proverbial "what gearing" list over the many years
So some considerations......the back stretch seems shorter than Roebling's straight.....the 180+ degree turn at the end of that straight seems rather tight
so how about comments on this selection for a 10/31 diff '94 Pinto FC 1st = 17/33 (0.5151) 2nd 18/28 (0.6428) 3rd = 21/27 (0.777) 4th = 19/21 (0.9047) Note I think backwards from how some people discuss gear numbers but I've also noticed there are some that think my way. Roughly steps of 13's in between the gears
Thanks

Seattle; Pacific Raceway Park, and The Ridge are not listed here if anyone would like to share their recomendations.
Is it safe to assume that the bulk of the gearing here is for Pinto setups?
Would a Zetec car go up a gear across the board or......?

[BTennessen]

Planning a track day at National Corvette Museum motorsport park, could use some recommendations. I've ran the track a few times in other things but will be first time with the FF1600 on track. RF78, Avon radials and 10:31

[Bob Coury]

I thought that I had them-can't find them now.

Thanks!

[KMiller]

I already had that chart, but did not see T.H. Thank-you for your response

Please post your requests for baseline gearing setups in this thread. It will prevent redundant requests and also make it much easier to find.

Anyone?

Start with a 17/35 first and a 21/25 fourth. Fill in the other two equally, but be prepared to change them based on how you drive the track.

Tried scrolling thru 9 pages but I'll ask in case I missed something............

Vintage FF with 9:31 and vintage Hoosiers. Any suggestions much appreciated!

I have never run at Thunder, but one of the previous owners of my car had a data sheet that stated for use with 13/36 and 22.40 rear tire: 16/34, 17/29, 21/29, 19/23

Crossle' 32 on Toyos:

17:33 20:31 23:29 25:25 worked pretty well for me and my 6500 redline.
