Before making promises about collection, coordinate the inspection, paperwork, seller release and transport. Give each part of the purchase its own check.
The mass ratio of air to fuel during combustion. Stoichiometric (theoretically perfect) gasoline AFR is 14.7:1. Tuned JDM turbo engines run rich (11.5:1 to 12.5:1) under boost to lower combustion temperatures and prevent detonation. E85 stoichiometric is 9.7:1 — more fuel volume but cooler burn.
