What is the effect of the secondary air door drop amount? What I am referring to, is the amount that the air door opens initially, when the throttle is slammed open all the way. This amount can be adjusted anywhere from no opening to approx .180. This adjustment is made via the choke pull off linkage bending. My question is, what are the effects of a zero opening verses a .180 opening when the throttle is slammed open from idle? How does it effect initial bog off the line? If it matters, my car is a stock Challenger 340, with stock cam and ported stock heads. Thanks.
