Porshy -
Well, you came up with the idea.
MMNIAC delivered the requested experiment though.
The slippage did not occur until the tire was essentially hung, not as soon as the revolver started to unfold...
....as you explained, the proof of concept was if the slippage occured as soon as it STARTED to unfold...as from that point onwards, there would have been no difference in traction, if the myth had been true.
As the slippage only occured as the tire lost ground contact...and NOT upon initial unfolding....in fact, pretty much about when all suspensions let a tire spin...it proved that the concept of loss of weight/traction upon initial unfolding was false.
OK - One myth BUSTED.
Now, about the rest of them....
Stress on the leaves and hangers.
This should be easier at least for most people.
The claim is that the extra rotation the leaf pack can move through stresses the leaves and hangers.
OK - if I take a regular suspension leaf pack, and twist it in the middle, it transmits this force to the front and rear..the front leaf hanger, and the rear shackle, and through the rear shackle, to the rear shackle hanger...as these points are more or less fixed, the leaf is bent/twisted, and has tension on it...as it is the only mobile part.
This is the normal way its done...and we've all done it...fine so far.
Now, lets make the rear shackle able to give/rotate with the leaf.
I twist the leaf, and the front hanger has forces transmitted to it...and the rear revolver shackle has forces transmitted to it....so far, the same as for a regular shackled suspension.
Ok, I twist the rear revolver with the leaf, and it just rotates with it...so the leaf is not bending, and the tension is relieved...and no twist is transmitted to the hanger at all, as the rotation eliminated the tension.
So - the leaf is under LESS tension, and the rear hanger is under LESS tension....that's great...no damage likely there.
What about the front hanger? Its the same fixed design as the regular suspension...can't it be damaged?
Well - its as vulnerable as it was before the Revolver went on the other end...and, as the leaf itself is not being twisted as hard, it has LESS stress on it as well.
What if the Revolver allows the leaf to twist FURTHER than it would with a regular shackle?
OK - this is quite likely. The parallel situation is if a flexy spring pack were installed instead of a stiffer pack with Revolvers...as a flexy spring pack and lift shackles has about the same travel as a stiffer pack with Revolvers.
So - the answer is that the front would get twisted as FAR as it would with a flexy pack and no revolver, but not as hard, as the tension is relieved by the Revolver at the other end.
One situation is turning a screw driver to drive in a screw with your hand, turning the screwdriver a half turn...
...The other is like putting the handle of the screwdriver into a rubber hose, and turning the hose a half turn...
Its still 180 degrees, but the forces are transmitted into the hose, which is easier to twist...relieving the tension....
...and, with the hose being turned, the force on the screw to twist it into the wood or whatever, is greatly reduced...
As the screw into the wood is the equivalent of the force on the front hanger...you can see its more gentle.
Because I have not heard reports of undue front hanger breakage on rigs with flexy leaf packs, or on front hangers on rigs with rear Orbit Eye mounts...a similar flex inducer, it seems that the small additional degree of rotation involved would not be of special concern.
Of course, I HAVE seen and heard of front hanger LEAF breakage on several X's...including a few that did not know the leaf had broken inside the hanger...as the ends were still captive, etc...
So, that happened on OEM suspensions, and on PML, and 3" SL's, so far...in a few cases.
IF it WERE to occur on a Revolver equipped rig (It has not happened yet though as far as I know....), it would not be a Revolver specific issue, perhaps the previously discussed Nisan leaf metal issue, etc.
I have also heard of rear shackle mounts breaking, and rear shackles breaking, on non-Revolver equipped rigs...so, while it DOES happen, it is not a Revolver specific problem either.
I did hear about one (1) guy who needed to repair a Revolver Shackle, I believe he upgraded the block the shackle folds onto from what it came with. The new ones seem fine in that regard.
So - there is no sound basis for the Revolver to damage the leaves, or the hangers, or atleast, no more than any other flexy suspension, and probably a lot LESS likely than a conventional suspension.
Porsche - do you concur?
