What RPM's should I launch at? Last Friday I was just kind of "feathering" the pedal and was launching around 1700-2000 RPM's on street tires. I had a little bit of spin but not much. I ran a 9.37(1/8 mile). I'm getting 4.10s installed tomorrow so I know it will be waaaay different. What RPM's do you guys recommend? I know I need DR's but thats on the way after the gears. Thanks in advance....
