IC and traction at different parts of track
Jerry Bickel's chassisbook says that long and low IC generates less initial tire hit but keeps tires planted for a longer time. Short and higher IC hits the tire harder, but doesn't keep the tration after that so well. I understand the the initial tire hit at the starting line but how much longer time with long and low IC? 1 second? 330ft? 5 seconds? To the half track? 1000ft?
For example for high rpm sbc with manual he sets car up with long and low IC because it hasn't the power to shook the tires farther down the track.
