what's usual ft-lb gained per degree of timing adv near MBT for single turbo rx7's?
 

I was curious to know the approximate ft-lb gained per degree of timing advance near MBT for single turbo FD rx7's. not many solid data points available.. knowing some concrete single turbo FD MBT data points would help inexperienced tuners gain some confidence while approaching the MBT when tuning on dyno. it would give me some sensible limits as well... thanks in advance!
