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.

[Dirtrunner35]

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.
