Pinion angle?

How much pinion angle change would you guess??

[DaveBauerSS6]

Trying to figure out why there are no replies.

I can tell you its not a trick question.
I don't think there are any wrong answers, because we cant measure it.
I hope the link is good.

I'l start and say it's 1 degree.

Anyone have a guess????????

[dirty white boy]

hard to guess the way it looks with rear end jerks right before any real noticeable angle change,..try mounting camera on rear end so we can get a accurate view of any noticeable change but id say round 3 degrees...

Not my car, I found it on the tube. I have a 3 link Pro Stock and found it interesting that the pinion wasnt moving much in this video. This looks like a Northern sport mod, but the suspension looks the same as mine. just wondering.

To me it looked as the Pinion angle was not hardly moving, if any. JMO.

Not moving

Not changing much at all since the pull bar is solid.

After watching this , Im putting a camera on mine. Looks like I'm running with too much angle.

i use a flip cam, with a ram-mount from bass pro and mount it on all kinds of bar sizes. good cheap price for the cam VS a go pro.

What's the recommended pinion angle on a 3000 lb. metric car on a semi banked dry slick slack ? The car has no pull bar, j-bar, and is not a 3 link. Thanks, Ricky

15 deg on the angle

I run 5-7 deg with stock 4link suspension.

I run 5-7 deg with stock 4link suspension.

Hows that work...aside from adj. Uppers...

Or why change it back and forth, I should ask?

I run 5 degrees in the IMCA Stock Car metric.
I use the formula of the amount of pinion change plus 1 degree.The pinion change varies by the type of suspension. You want a preload on the pinion on full torque to keep the suspension loaded.
Not enough angle can go to a whip on acceleration and run the pinion past center unloading the suspension. Too much and you are fighting friction loss in the u joints
.In the video of the hard 3 link, my guess of 1 degree would be a 1+1, a 2 degree total.

Thanks for all the information. Ricky

Correction on angle, I thought you were talking about top bar angle. Just about all of the WCSS are running 10 deg. Set it and forget it.
