After some feedback, in the interest of tuning, and learning how to make the SW configuration work better for us, Race manager will relax the Chassis/body pod and drop arm requirements.Any hardness NSR parts allowed. Motor will remain the stock King 21/evo.

-Warren ZevonNovember 2, 2025 at 1:00 PM in reply to: 2026 H2 – NSR Porsche 997 Challenge – Road & Rally Track #23509ATTENTION ALL:
Some details are coming to light after the initial draft rules were written.
I Would like some discussion on road track voltage, would like to test 11 volts)
Will we have A and B classes? Separate heats? Different road track voltage?Also, for the rally track, I think alternating the direction each event, rather than a coin toss for this. Coin toss can determine initial direction.
I think it would be best if we could somehow ensure we have half the races on one track and half on the other. For example, if the coin toss too heavily favors the rally track, after 3 rally races, the remainder would be on the road track.
Hope this all makes sense.

-Warren ZevonNovember 2, 2025 at 12:51 PM in reply to: 2026 H2 – NSR Porsche 997 Challenge – Road & Rally Track #23506Brian,
Please make the following corrections/additions to the rules:
Road track races will be 60 laps, run head to head, rotating through in the usual round robin fashion.
"Enjoy every sandwich"
-Warren ZevonAlso this addition for the 997 challenge:
Racers must select a livery prior to the series.
No more than two of the same liveries are allowed."Enjoy every sandwich"
-Warren ZevonFor the NSR Porsche GT challenge, there was some consensus last week to make it an all angle winder series. If there are no objections could we update that in the rules?
Also forgot to mention in rules that the usual ballast rule is in effect. (Topside of chassis, no weight limit at this time)
Thanks!

-Warren ZevonIf the Targa Florio is viewed as a continuation, I would like to propose the NSR Porsche 997 Challenge. Rules below:
NSR Porsche 997 Challenge.
This is a Box-stock time-trial series featuring the NSR Porsche 997. The idea being the cars are as close to stock, and to each other as practical.
Stock chassis motor and pod, wheels, NSR tires. Can change out guide for another NSR guide, Ballast OK, that’s about it.
Race format: 60 laps on road track, (lane TBD by lot) or 40 laps on rally track.
Alternately for the road track , we race head-to-head, as usual, but set the software for 60 lap heats, not 5 minute heats.
Track choice to be determined by coin toss AFTER TECH.Body
The body cannot be modified in any way.
The stock plastic cockpits and glass are mandatory

White kits are allowed but must be painted, or uniquely decaled. At least two numbers must be visible.
Duplicate liveries are discouraged.

Varnishing the front tires to make them slick is not allowed.Track Power:
• Road track: 12v. Rally track: variable"Enjoy every sandwich"
-Warren ZevonLast I heard class b might be running separate heats at a lower voltage. That means a different setup somehow in Race Coordinator I guess adding two races ASCC 2025 NSR F22A, and ASCC 2025 NSR F22B?

-Warren ZevonProposed rules for ’70-’73targa. Scale calculation rule has even dropped, but will be looking into a limit of (2?) per event on any specific model. Any feedback welcome.
Targa Florio 1970-1973
This series will be run on the rally track. Direction will be determined by coin toss.
Track voltage is at entrant’s discretion.Race Fees: $5 Premium members, $10 Standard members; $15 guests
Cars eligible:
Any car that was entered in the Targa Florio in the years 1970, ‘71, ’72, and ’73. Cars that were DNS, or DNF are fine. (Partial list will be provided later)Models allowed: Any slot car that is a reasonably scale depiction of the above.
Must be within 12% of 1/32 scale plus or minus. That is a 24% window. Thunderslot models, for example, are too over-wide, and are not eligible.Cars must have driver figure and Steering wheel. Lightweight interiors are okay. Glazing must be in place. If your car has a navigator figure, you do not need to remove it if you want to keep it un-modified. Historic liveries are not required, but very much encouraged. Avoid duplicate liveries if at all possible.To avoid The series becoming too overloaded with a single model (Porsche 908/3, or the Lola T280/290, for example) We’re considering a limit to how many of a given model can race on a given race day. We want to se a more varied selection of entries this coming year
Please post a picture of your car (s) Model, or 1:1 to the rules thread, so we can get an idea of what cars and liveries will be entered.
Motor, gearing:
OpenAxles, wheels, tires:
Axles, bushings, bearings open. Wheels must be a good faith effort at scale, with inserts. Maximum wheel/tire width 10mm front and rear. (This may be subject to change)
Tires can be any rubber or urethane compound. Truing and gluing is encouraged. Coating of front tires with nail-polish, C/A glue, etc is permitted.Chassis and drive layout:
Chassis must not scrape or rub track surface.Braid, guide, and motor leads.
openGeneral
If it is not mentioned – contact Series Manager for legality (BEFORE the first race). Cars may be presented to Series Manager any time before the first race for a test inspection."Enjoy every sandwich"
-Warren ZevonLast year I had a lot of trouble getting my magnetic downforce within spec. Does anyone know if rotating the motor 180 degrees might make a difference?
"Enjoy every sandwich"
-Warren ZevonHere is a proposal for a series using both the rally and road tracks.
NSR Porsche 997 challenge. (Box stock series) Stock chassis motor and pod, wheels, NSR tires. Can change out guide for another NSR guide, Ballast OK, that’s about it.
Race format: 60 laps on road track,(lane TBD by lot) or 40 laps on rally track.
Track choice to be determined by coin toss AFTER TECH.
"Enjoy every sandwich"
-Warren ZevonMaybe three 20 minute heats for the endurance race would make more sense, what with there being three lanes.
"Enjoy every sandwich"
-Warren ZevonLast race some of us were kicking around the idea of an endurance race series. Here is an idea for that:
Slot.it Group C endurance race series
Spec series with car rules very close to, or identical to previous group C series.
Race format would be something like this. Races held on road track. There cars, Three teams, four 15 minute heats. I think that would be enough to give everyone a turn at the wheel.
Also, Would like to continue Targa Florio with the 1970-1974 epoch. Open series. Many cars that people have previously run in other series would be eligible, such as DeThomaso PAntera, BMW 2002, Renault Alpine A10, Lancia Stratos, Porsche 911, Fiat 124, Porsche 908, Alfa T33/3, and others.
Rules very similar to current series, but most likely doing away with the confusing scale calculation.

-Warren ZevonNot too late. Feel free to run them.

-Warren Zevon
First apologies. It seems I was going on bad data when looking at Thunderbolts for the Targa Florio. Marty checked on his own, and indeed the Thunderbolt Lola coupe is legal for the series. Sorry for the mess-up, I will do better in future.
-Marc
"Enjoy every sandwich"
-Warren ZevonCouple questions about current official rules posted.
Are we still limited to sideways and slot.it guides as it says in rules, or is the series open?
Is it okay to coat fronts with Nail varnish? I ask since it is very different than oil soaking.
Thanks 🙂
