A/F help for n/a,and for bottle..lq4 fox Long story short:
Went 11.00@123 on motor with a/f at 10.2:1 or so...real fat..prob 6-7 months ago..
Been tinkering with jets lately,got the all motor a/f to 13.2:1 car feels real strong..
Well got a good deal on a used NOS cheater kit set at 125 shot..
My question is what would be a decent a/f on bottle?,and about how much timing should I pull for the shot?..on 110/91 octane mix,with a br7 plug
Plan on going to the track this Friday..hoping for high 10's on motor now,and possible low 10's on bottle..you guys have always been a big help when I'm reading the threads..thanks for any help

What't your combo? Motor, stall, gear, tire, weight...sounds like a strong car.
I think the consensus is 12.0 - 12.5:1 afr on spray. BR7 plugs and pull 2 degrees per 50hp of nitrous. More than safe starting point considering you are adding race fuel.

My car runs best at 13.1-13.2 AFR on motor.
Each motor is different. I'm on a 100 shot and using 93 octane I have to pull 8 degrees from motor tune with br7's gapped .030"
