Any of you that think the drawing I showed is CORRECT.......then there is no need for me to even continue in this discussion. In a RACE CAR, if you think it is desirable the have the u-joint over center, making the shaft and pinion come together to form a teepee, then there is nothing left for me to say, other than you have no clue how to set up a RACE car.
And whoever said the driveshaft doesn't even come into play as far as "pinion angle" is concerned is DEAD WRONG. Pinion angle is nothing more than the angle of the pinion TO the driveshaft, so yes, the driveshaft matters VERY much. The rest of this crap about parallel angles is "driveline" angle and does not matter when it comes to pinion angle. All I can say is Google is your friend.
It's apparent some don't get it and never will, so the rest of you can hash it out from here......McAllister, Bob George and a few others get it, but that's a short list........LOL!!!
Skicker........the bottom drawing is correct
