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.
Yep the goal is Parallel "under power" in a "straight line" like you say.
But , with the majority of the cars here, the Parallel wont be in a straight line.
Therefor, the same goal is to be Parallel "under power" even if the tranny centerline and pinion centerline are not pointed at one anther like some of you race car builders would do then adjust from that.
The Goal is the same.
The Argument,
Measure off the pinion/driveshaft
Measure off the pinion/trannycenterline.
IMO, If you havent pointed your tranny centerline to the pinion.
Measure tranny centerline VS pinion centerline.
80% of us here fit that.
If you built your ride for a Parallel tranny and pinion angle centerline setup, you can use the driveshaft method and be just as accurate.
Further, besides all of the above, there will be no perfect Pinion angle setup in the real Dynamic world for most of us here, the movement at the rear is pretty dynamic.
