enough said if you buy into that, you can also find just as many who set it the other way. really I don't care how anybody sets theirs. people have to decide for themselves and learn the hard way I guess. now go make you another movie.
untill you build a 4.70 1/8th mile stock suspension car i will keep listening to the guys who do. no need for a movie
have at it. cause I have no desire to build a stock suspension 4.70 car.
why not u sceeeeered
no not really, you sponsor it and I will build and drive it. how does that sound? when can I expect the first sponsor check?
car never make it off the starting line and you would be blaming all the horsepower you make to the guys cleaning up the gear oil
oh yea? where have you ever seen me say anything about making big HP? thats something you have made up to be funny.my junk don't make a lot OF HP and I really don't care.

Wayne,
7 degrees is too much negative pinion angle. If you are going to quote me, please post where I told you to run that much.
This isn't rocket science. Depending on the ride height and drivetrain angle of the car, setting pinion angle off the driveshaft is purely hit or miss.
For example, assume your race car's pinion angle is set perfectly and the car has no vibration.
If you raised the engine in the front 3 degrees, changing the drivetrain angle downward, the correct way to compensate for this would be to increase the pinion angle 3 degrees POSITIVE, because it keeps the pinion parallel to what you had before.
If you tried to set the pinion angle off the driveshaft alone, you would increase the pinion angle 3 degrees NEGATIVE, most likely causing a severe vibration because of U-joint binding.
BTW, this is also the correct method to set pinion angle on a lifted 4 x 4 truck with a 1 piece driveshaft:
1. Make the pinion parallel to the transmsission. 2. If pinion binds, lower transmission in the rear. 3. Reset pinion parallel to transmission. 4. If pinion still binds, install a CV joint on the transmission, and point the pinion directly toward the CV joint.

your way, what is pinion angle when trans and rear are parellel? ZERO???? SOMEONE PLEASE ANSWER THIS QUESTION BECAUSE NO ONE EVER DOES

So then your pinion angle is set wrong if you are breaking rear ends .
the rear ends that broke had nothing to do with pinion angle, thats another myth made up by sixpackgut. they were 30 year old passenger car rears.

yea I'll still feed you, but your probably not going to like the taste of what I am thinking about...

not sure what your asking is why you don't get an answer. how often do you run into that situation? maybe on a chassis car you would. and the only thing you do is roll the pinion down depending on what suspension you have.

I never said that you said to run that much, I only said that I did it that way and it didn't work that way with me using 7* on my leaf spring car......Yeah, obviously it was too much when doing it your way, or it wouldn't have howled like crazy ........What I am saying is that I've run that much for 15 years, doing it my way, in all kinds of cars and have NEVER had an issue with vibration..........
Quote:

I AGREE.......and my theory is that as long as the pinion angle doesn't go over zero with the driveshaft and it's not low enough to howl, it's fine in a drag car and WON'T COST ANY ET or "rob horsepower", or even a street car, so it's always been a "hit" and not a "miss" with me........
Quote:
For example, assume your race car's pinion angle is set perfectly and the car has no vibration.
The problem with saying "perfect" is that there's a pretty large window where the thing won't vibrate and it would be called "perfect"......
From doing what I'd done, it's obvious to me that if I had a jacked up 4 wheel drive truck and the output shaft and pinion were parralel to each other......and the driveshaft were pointed down at a 45* angle, and I then rotated the pinion down 2, 4, or 6* or whatever, it would REALLY howl........
The point is that the way you guys do it works fine if the output shaft and driveshaft are relatively parralel to each other.......
When I'd set my pinion angle the way that the Moparts chart shows , I had 11 degrees negative pinion angle to the driveshaft.......but it was only 7* down from the output shaft, which is what that chart shows..........and man, did it howl like crazy......
So, my point with that is, let's say we have an extreme example.........and our race car with a 4 link was set up similar to my car in that the engine were facing downhill.......and the pinion angle to driveshaft angle ended up being 11* different just like my car, even though the pinion was only down 4 degrees from the outputshaft, I guarantee that it would howl like crazy.........

if your tranny is 2* down and the rear is 2* up then it should be in parallel, correct? AT THIS POINT, HOW DO YOU GET 0* ( ZERO ) PINION ANGLE? ANSWER THE QUESTION

If the transmission slopes downward 2 degrees toward the rear and the pinion slopes upward 2 degrees toward the front (parallel), you have 0 degree pinion angle.
If the transmission slopes downward 2 degrees toward the rear and the pinion is level, you have 2 degree negative pinion angle.
if your front U joint is 12" from the ground and the rear U joint is 13" from the ground, there is no way on gods green earth this is correct.
