Proxy Track Voltages?

[cj74]

Good afternoon all. Looking to see if I can put together some additional inputs as I'm evaluating last and future builds. I know that most rules (including the Quick Slicks Proxy) indicate track voltage should be set between 10-12 volts, however it has become clear that a 2 volt difference can turn a great car into a complete turd.

After a couple of searches it looks like some hosts are including in their results, but I'm hoping for a simpler summary for reference.

Any chance of current or past proxy hosts posting a quick response with track voltage that you're current running?

I’ll put my 2cents in any car showing up here would run 10V on wood ,10V no mag on plastic and 12V with mag

the NERF club in mass races at 10 volts. My track ridgeline , and cornerstone in grafton mass.

Thanks gents!

Clover Leaf Racing 10.1 volts (under consideration for an increase)

I run 10 or 10.5 on my home track and most smaller tracks. The larger ones like @ the Scale racing center they will run as much as 13.

I good car can usually handle more voltage just fine IMO. Worst you should need is a change of gearing.

Thanks for the response Zack. I'm not asking for general track voltage. I'm asking specifically for the voltage that is being used when hosting a proxy.

Once a car is sent for a proxy, there is no opportunity to change the gearing.

11Volts I race at MID-BC.

My two cents.....when building a proxy car you need to test / tune at 10V AND 11V. I do not test / tune at 12V (or more!) because not many tracks run at 12V on the typical Proxy tour. 10V and 11V covers most tracks. Just my opinion on what I like to do.

Thanks for the tip Rob. I have been testing at only one voltage setting. I've only tested at one or the other. Now I need to figure out how to bribe the guys at the track to change the voltage on a whim.

I run my new track at 10.5v
It's a shorter track, 3 lanes - 56'.

[War Eagle River]

10v. Never changes.

[SuperSlab]

I typically run proxies at 11V. Long, fast track

10.5 volts here

[modernslots]

SCANC proxy tracks - SlotZuka, Woodland Trace, Bent Tree, and OFI -are all currently at 10.1 All are routed MDF.

Running at a higher voltage will magnify any handling problems that a car might have, so if it is possible it would be a good idea to run your cars at 12 volts to be sure that they will at least be drivable. Issues like the car having hop and chatter or doing wheelstands may show up. Possibly a car would need extra weights, a different gear ratio or a less powerful motor.

We also run at 10.1V here at The River Run.

We’ve tested 10.5, 11.0, 11.5 and 12.0V and we don’t see faster lap times than at 10.1V when we take the voltage up; all we see is more de-slots.

It’s track specific; for routed wood tracks with no magnetic attraction to the rails (copper tape and braid) the longer and the more flow a track has to it, the higher you can take the voltage. Shorter, more technical tracks with less flow do better at around 10V.

Run Nashville Speedway oval at 12V. I also test all my proxy cars at this voltage. This is a Scaley Plastic Track.

Thanks again to all for providing the voltage information that the proxy events are running at your respective tracks. As feedback comes in from different races and classes it is helpful to have this as a data point.

I will likely put this info into a simplified table for ease of reference.

A few good point along the way regarding testing and tuning as well.
