Transponder Mounting

[veeten]

Working on a Stock Car that will be Road racing soon .
The transponder is mounted in left rear per rules of former life
Is there any advantage to moving it up Front where I have always
had them on formula Cars?

[DanW]

If your race sanctioning body scores position visually by the timing and scoring team, then placement in the rear of the car is fine and likely less vulnerable to damage from a shunt.

If they score position solely by the transponder, then put it as far up front as you dare...

[Rick Iverson]

Yep.

…..If they score position solely by the transponder, then put it as far up front as you dare...

Thanks for the Info. I plan to move transponder to front.
If I mount it on radiator support it will have to shoot through
a thin maybe 1/8th carbon fiber shroud .
Will it go through carbon OK.
I know it will go through Fiberglass OK,
If not, how big a hole do I need to drill.
Thanks

Since it is supposedly a magnetic signal I think CF will not bother it - if it does, here is a link on the hole needed.

Carbon fiber functions much like a Faraday Cage. It does interfere with transponder signaling.

Peter;

You are in deed, a wealth of knowledge. But is there a thickness limitation.

Never had the offending CF measured for thickness.

I had a car come through my shop last week that had the transponder mounted sideways. I thought to myself, that's frigged up and I should correct it for the customer but then again, that's how it's been working for three years that I've known the car. Screw it, I'll save the customer a half hour of labor time and leave it be.

Would indicate transponder emits 360*

If it is pointed forward he may be on to something.

[Rick Iverson]

Brilliant.

I’d think twice about getting way up front in case of s crash. The old AMB ones are really rare and those new subscription ones are a pain or got me it was. I got my money back after getting yo the track twice and not working.
