3.07 vs.4.10 et difference

[K*A*B]

i'm sticking with the 4.10's for a little while

similar conditions meaning around same temp and humidity , i ran 14.60's in the winter and early spring , then in the summer it seemed to drop off a little (1 tenth) when the sun goes down , if the sun is out and its in the 90's it ran low 15's , now it will stay in the 14's

do you have any idea how lucky you are to have 4 seasons of racing?

 

[K*A*B]

yup , atco rocks , they usually only close for a couple weeks around the holidays , throughout the winter they are open every sunday (weather permitting)

man give it time your car will run better, you have to record everything not just temp

 

[K*A*B]

i know it will run faster , and the altitude density and track conditions were similar
i have been racing for 16 years , i have bracket raced several cars , the atmospheric conditions were not even 2 tenths off from my winter time passes
tuesday night is a bracket race night at atco , my typical routine involves walking around through the pits and asking the other racers how the air is and if their cars are running correctly
i'm getting the proper speedo gear tomorrow to see if that may have affected anything , i ope so i don't feel like swapping these things again ....lol

oh I ran 14.8 with the wrong speedo gear, and 14.3 with the new one FYI I dont know if it relates or not

FWIW, when I installed the 4.10s in my '93, I did not think it ran or shifted properly until changing to the correct speedo gear. :steering
