Soo we have a local private airstrip that we have fun runs on and id like to have the best setup for that, I have a Paxton car on 10lbs with a 3.90 gear. I just came from a 26.5 inch tire to a 27.7 inch tire and honestly the car felt like it pulled harder? I do 40 and 60 to 130-150 rolls mainly and track time 8th mostly. Should I go back to a 3.55 or a 3.31 and would I actually go faster? Help me understand because I figured with the torque multiplication of the 3.90 itd actually help?
