You won't be able to slap up 10.900's all the time.
Do you have a good weather station ?

Could you define a "tad" high? Rick and I both run super comp and I know my ratio is around 2.8 to 1. I would consider 8 to 1 to be excessively high, but maybe in a heavier SST car the ratio will be higher considering the weight of the car and the HP of the car. What kind of ratio, and what kind of MPH do you run with your car? The car in question ran a 10.75 with only .6 in the timer 2 so it doesnt appear to have a lot of extra HP. Maybe it needs that much ratio to work. According to his posted numbers, the ratio he came up with appears to work. What does the car in question weigh and what does it run full out? I was looking at some of your posts in other topics and should ask you are you using the 3 speed or glide and are you shifting on time or by rpm?Also, what is your first timer?
