the Derale pan I'm using has finned tubes that pass through the oil in the pan. this one to be specific https://www.summitracing.com/parts/der-14204
Yes it seems to coincide with the throttle. I am sure we change the harmonics, which why we need to fine tune after we make changes. My question is whether I have enough down so when it points up the angle is still in tolerance.I've watched that video a couple times and it seems like I can see the yoke on the diff angle up and then down just slightly and I was wondering if that was due to you being on and off the throttle. I also can't help but wonder if by all the upgrades and mods we do to our rigs if we don't change the harmonic frequencies of things.
Mine is @ 1* down make be just a touch under 1*. I need a better angle finder, hard to get an accurate read needle is to fat.When I was setting mine up (cv style) everything I saw said the dif/shaft interface should be straight relative to one another. With that being said I think I put mine about 2deg down from straight, so under load it was very straight. No wobble. Whats your measurements on that?

In which direction are the shims?I ended up getting a purpose built tool.

I am 9.1 on the pinion and 10.1 on the drive shafts with 4 degree shims. Should I try 5 or 6 degree ??
