What gearing are people running for a 8.5?

Got a 21 in mine

23t indoors, 25t outdoors.

I'm running a 6.5 and run a 23 pinion. I'd have thought a 24 or 25 would do depending on the length of the straight.

24t/25t I am running on my 8.5 and 26t on my 10.5

According to the manual on a nosram 8.5t use a 23 pinion.
I use the kit standard 22 pinion on a 7.5t

Canny because anything less than a 22 won't fit when you're running 3deg anti squat because the motor hits the rear pivot block unless you run a larger spur.

I'll probably drop to a 22 indoor because I can't run anything smaller.

Still a great car though.

I'm running a 24 pinion with a Lrp X20 8.5 and this feels perfect.

Started with a 22 but even on a small track the car tops in the middle of the straight.
The pinion also depends on the motor u use, speed passion for example likes a higher pinion ( 26/27)

ended up on a 24, with timing turned up as far as the speedo will go

I'm running a sp v3 7.5 with a 22t pinion on a medium indoor carpet track.

Im on a 25 with a orion 7.5 and some timing on the motor, we have a long straight.

7.5 22t boost 6.5 24t no boost
