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

Rick,

I just did a review with Taylor for my 84 Reynard CFC 10:31 ring and pinion for RA.

Here is what they recommended for me and what I found out from various sources.

1st - 18:32 = 1.77
2nd - 20:30 = 1.5
3rd - 23:27 = 1.26
4th 24:26 = 1.08 or 25:26 = 1.04

If you run Grattan also, you will see the ratios there are very close and you can run the same ratios if it is an occasional event Vs your home track. I have not run Road America and am looking forward to the June 17 - 18 race. Perhaps someone who actually has run RA with these or similar gears has a view.

I would contact Taylor and talk to Craig and get his thoughts.

Taylor Race Engineering has it at:

• 21:25
• 25:27

These are not even close. Any help?

Has anyone come up with anything yet?

Anyone have gears for Pueblo? I raced there (what seems to be) a long time ago in a DSR but have no notes left and I don't find any on the thread. Seems like they were like Lake Afton- another indication of my age. Thanks for any help!

Anyone know what gears to run for the HPT "Runoffs" course?

Dave- I ran in my FF 17/34,19,32,22/30,24/28.I prepped the FC that finished 2nd to N. Coello and we had 18,34,20/32,22/29,24/27.It is a good starting point.

Thanks, Mike!

What rev limit and tire circumference were you using with those gears? I assume it was a 10:31 R&P.

Can anyone advise as to the gears I should try for the current (with chicane) SCCA long course at Pocono for a 10:31 final drive??

Ian- This is what I dug up for Pocono (pro) Long course. I am running a close derivative (I dont have all the exact ratios)
Suggested 19:33, 21:30, 23:28, 25:26


Say hi to Doug, see you guys Sunday!

Can anyone give me a starting point for gearing Mid America (near Omaha)?

Seems my cars are going to Canada. And I promised Gear-sets to match. sooooooo any body ever hear of a track called Race City Calgary? and knows what FC MK9 gears work there? :confused:

Thanks
Phil

It's my first trip the Gateway in this car so I did a search on the subject and folks have hit all around it but nothing definitive for FC. Is anyone using anyone using a 25:27 or 24:26 (or????) 4th? Some are using 24:27 but that seems low...:confused:

Travis at Taylor Eng. was helpful but admitted their data is dated & not definitive either (3 different numbers).

Thanks,
DaveK

Hi, Could someone share their baseline gearing for Thunderhill and Laguna, please? Also, is there a site to better understand the methodology of selecting gears? Thanks!

VIR...Anyone care to venture a gear selection for Club Ford at the VIR North Course. 9:31 R&P.

Thanks,
Mike

Hello, I just found this site tonight and I am going to be looking for lots of info on FC racing. I bought a '90 Reynard recently and the car will need lots of attention before it can be run again. I plan to run the car in autox and solo I events so that I can learn to tune and prep the car. Later on I would like to run in some drivers' schools and possibly some road races.

The car is set up with 10:31 r&p, and the following gears: 1st 18:25, 2nd 21:30, 3rd 23:28, 4th 25:27.

Can anyone suggest possible gear combos that would work for medium speed autox events? Thanks,

Anyone have gear Reccommendations for Summitt Shannondoah Course... FC w/10:31

I'm looking for some gear hints for Mosport in Ontario, Canada. I'm running an '84 Reynard F2000 with a mk IX hewland, 9:31 R/P, 22" rears, and 7K rpm limit.

Even min/max speeds expected in an F-2000 on Mosport would be a good start!!!

Thanks,
Gary

Hi All, I did not see Barber listed. Anyone? Bueller?
Might just have to run it as a 3 speed box!

Basically the same gears as CMP...

ALL 10/31 R&P:


In '04 with the Tatuus @ Barber:

17 17 21 24
33 28 29 28

Sean's gears in '03 Barber: (yes Sean, I keep everything)
FirstSecondThirdFourth
19 22 23 24
32 30 29 27

Sean's gears in '04 Barber:
FirstSecondThirdFourth
18 20 22 21
32 32 30 25

Mike's gears in '03 Barber w/Reynard:
FirstSecondThirdFourth
18 20 22 24
33 30 29 27


Tatuus in '05 at CMP:

19 21 22 24
32 31 29 27

Sean in '03 at CMP:
FirstSecondThirdFourth
19 20 22 24
33 30 30 27


Tatuus in '04 at CMP:
FirstSecondThirdFourth
17 21 23 24
28 31 28 27

Reynard at CMP in '03: (CFC lap record at the time)
FirstSecondThirdFourth
18 21 23 24
33 31 29 27



I think Sean liked his '04 gears the best...

That was rather succinct and as usual, quite forthcoming and factual.

Anyone have any ideas about gearing a 96 VD for Sandia Motorsports Park in Albuquerque? I did some driving there a few weeks ago and felt I should have been running lower gears. I was just wondering if anyone had any experience there.

:confused: Autobahn Gearing South Track

BASELINE GEARING FOR MOST TRACKS

The Midwest Councill Sports Car Club is holding a race at Autobahn Country Club in Chicagoland area on Oct. 6-7, 2007. Last year the SCCA Chicago Region held a regional race at Autobahn on the South track which is 2.1 miles and 15 turns.

From the guys who ran the SCCA event last year including Keith Carter, did anyone come up with a good gearing selection for the track??? I know a lot of guys were changing gears after the first sessions.

If you check out the Autobahn web site http://www.autobahncountryclub.net/ you can see the course layout.

The South Track looks like you might be able to run similar gears as Road America.

Does anyone have any gearing ideas for Autobahn South Track for FC or CFC?

Terry

has anyone run and like to share new base line gearing for the new confiuration at hartland park topeka, fc , 10/31

thanks-doug rocco

Last year I ran: 18/33, 20/31, 22/29, 24/27. I don't think the track changes will make much difference in gearing. I am going to start with these again this year.

I tend to run taller gears than most, so maybe a tooth down from that would suit you better.

From what I heard there seems to be some different thoughts on first gear but fourth gear is just slightly faster.

1st 17/33 or 18/34
2nd 18/29 or 20/32
3rd 22/29
4th 21/24 or 24/28

thanks dave, see you there

Does this sound about right FC @ Pocono North Gears w/10:31 R&P

1. 18/34
2. 20/30
3. 23/29
4. 24/27

Anyone have any gearing reccommedations for the NJMP Thunderbolt Config?

With all the racing that went on this weekend at Thunderbolt, anyone willing to share baseline gearing suggestions?

I heard an unverified rumour that the fastest guys were close to VIR gearing.

It's a much faster track than first appears.

I practiced two seconds under the current S2 record in my Lola and used Summit/VIR 1-2-3 and a 24/27 top. Worked fine and hit the right rpm point at braking for T1 (beginning of the curb). Nice track, fun and fast. T8-T9 is a tough little booger.

From the baseline gearing sheet, it appears that VIR requires gearing similar to that required for Nelson Ledges, or maybe Mid-Ohio.

I used 19/32, 21/30, 23/29, 19/21 at both M-O and Nelson, when I was there last in 2007.

Anyone have any updates on that selection based on using the Hoosier radials?

Now that the Thunderbolt track has had its first year of racing, does anyone have a suggestion for starting gears for the track (for 10:31 final drive)?

Need Formula Continental Setup Gears for NJ Motorsport Track - This is my first time attending the NJ Motorsport Track on June 6-7th 2009 and was wondering if anyone had the gear setup for Formula Continental (Pinto Engine). Any help would be much appreciated!!

Does anyone know a good baseline gearing for Reno/Fernley. Formula C, 22 inch, shift at 7000? Thank you in advance for your guidance.

Does anyone have a good baseline gearing for Fernley/Reno. 22 inch, shift @ 7000, Formula C, Pinto. Thank You.:revs:

I just did a site search and a top to bottom review of this thread and came up with nothing...

I'm guessing, close to Summit Main:

1- 19/33
2- 20/30
3- 23/29
4 -24/26

Anyone have any ohter guidance.

(Pinto FC 10:31) for NJMP Lighting (EMRA/FPR July 10-11, 09).

Going to the Mile for the double regional and am wondering if anybody has an idea for gearing selection. FC with a pinto.

Thanks

Thinking about the ARRC. Anyone willing to share base gearing for Road Atlanta?

Looking for Baseline Gearing for my local tracks, Laguna, Sears and Thunderhill. I will be running a 94 VD Pinto. Any help will be much appreciated.

Hi, Instinct,

Here are three sets of ratios for Thunderhill, mine is the 1st column, 10/31 R&P:

1st 17/35 17/35 17/35
2nd 20/32 19/31 18/29
3rd 22/30 22/30 19/25
4th 24/28 23/27 24/27

I use the same at Laguna and can't speak for Infineon. My motor was going soft last year so I would not run anything taller but still had a good time.

Cheers,
FW

Does anyone have gears yet for a 95 or 2001 Van Diemen FC car at PBIR, the new Moroso? 10/31 RP.
Thanks very much!!
Skip Weld

If anybody has run at Spokane, would you be willing to share gearing or setup advice?

Thanks,

Daryl

Daryl,

We've never run Spokane. But Michael Lensen has. Get ahold of him. He will give you gearing.

If you cannot find a contact for him, I'll try to get his E-mail.

Rick Broadhead

Anyone have any guidance for gearing they might run with a 10:31 at Barber on Hoosier 7" and 9" tires? Thanks.

Need suggested starting gears for the NJMP Lightning track.

Hey All,
Got a friend who'll be running Barber Motorsports in Sept. in his 97 VD FC. Any suggestions on good gear ratios for that track. Any input is appreciated. I'll be running CSR.
Thanks, Tony

You should really check the Baseline Gearing thread stickied at the top of this forum...

FC Gearing for Barber Motorsports Park

Fellow FC racers:

I have looked through the baseline gearing chart here on Apex, this is great information so Thank You.

The gearing that is suggested with a 10:31 is:

1st 16/35
2nd 18/33
3rd 20/30
4th 23/28

This is great information but Hewland nor Webster make an 18/33 for the LD-200.

So, I am asking for advice on gear ratios (10:31, LD-200, 1991 VD FC, 22" rear tires) from fellow VD FC racers that have run Hallett.

Thank You,

Aaron

Aaron,

I run COMMA at Hallett and run the following gears in my RF2000 FC.

17/34
19/33
19/27
23/29
