And Quicktree, if you have to ask me what positive pinion angle is, why are you even IN this discussion.

And still.......NOT ONE GURU has answered the question. Which WAS, if the front joint is lower than rear joint, the trans points toward the ground(and since some are SO caught up in exact numbers, lets say 3* tail down), which means the shaft runs UPHILL to pinion, would you roll the pinion UP 3*, to maintain a parallel angles, even though that HAS to put the joint broken over the WRONG way(positive).......when we ALL KNOW, or at least SHOULD know, that on acceleration the pinion climbs MORE and will make that joint angle even MORE wrong............waiting on an answer

How about a picture. So according to some of you THIS would be considered CORRECT since the engine/trans and rear are on the same angle. Even though the rear joint angle is over center and going to get worse on accel.........OK, find me a chassis guy who would set a rear angle up like this on a race car, thinking that is good to go and I will be quiet. For further clarification, we will even say this is where it is under power. Now I was always taught, that you NEVER want the rear joint to go over center under power in a race car.........but apparently it seems all those people who say that are full of hooey......LOL!!!
Monte you know I am not asking you what positive pinion angle is. I was asking you what you were basing your statement off of. what is it in relation to. Positive to what??????

Positive with respect to the back end of the driveshaft. Monte has explained several times that the driveline (trans/engine angle) is not considered, only the relationship of the back end of the driveshaft to pinion. Under power, you want the pinion to be in perfect alignment (or as close as possible without ever going positive) with the back end of the driveshaft, so you'll want to set the pinion angle several degrees negative with respect to the back end of the driveshaft. Hopefully that is an accurate interpretation of what Monte is trying to drive into the skulls of the unwashed masses.....LOL
get out of here, we are talking cars that go down a track not show poodles laugh2
