Road Racing - AFR tuning

Hello,

I would like to know what you guys think is rich and lean for a roadcoarse car.

Thanks

I don't think you would want to go to the extremes that drag racers do, because a road course is a lot longer than 12.5 seconds so you want more longevity from your motor. IMO 12.7 to 12.8 makes sense for a NA road racer.

I tune for 12.2 on the street, N/A engines should be between 12.4-12.7 for max power
