Sorry, but I don't need that worthless chart to know how to set the pinion angle in my race car.......LOL!!
Only ONE thing to remember in a race car......Angles eat power. So while "under power" the want the driveline in as straight a line as it can possibly be within the parameters of how the parts are mounted. Set pinion angle accordingly. NOTHING else matters.
Jeez, the only reason for posting that chart was to show that a driveshaft is NOT necessary to set pinion angle. This topic seems to get tempers flaring. Bottom line is trans and pinion need to be equal and opposite angles under full power. If trans centerline slopes 2° down toward rear of car then pinion needs to slope 2° up toward front of car under full power.
On the chassis cars I build there is ZERO angle at load.. no parallel of anything... its a straight line as I said earlier in this
