Hello mate
It really depends on the track...
Is it low traction or high traction? Are there any really big straights or is it small and technical???
I would start of with a 23 as I have found to be a good starting point for a 7.5 motor...of course that applies to previous generation motors
Hope this helps...
Regards
Argi

I run 81/24 on a Ballistic 7.5. This is spot on for a large track like my local at Southport.
