Tranny/engine mount wear?
I thought I saw something a while back about a tranny mount insert that crumbled after being installed for some time, but I cant find it now...
Anyways, with a set of inserts or new mounts, how long do these usually last?

Never seen them wear out.
BTW, if you're looking for a set, I have a ZZP side engine mount AND zzp tranny bushing inserts. Both are in excellent condition.
If you're interested let me know, not looking to make a killing off them.

the mounts i do ast forever rotate the engine and take away power hop, also no vibes. contact OTT performance.

Solid mounts eliminate wheel hop and also stop engine movement, maximizing torque to the wheels.

Even with that tranny mount mod, you still have engine/drivetrain movement. So yes you may have eliminated wheel hop, but you still have movement which is taking engine torque away.

Solid mounts also put un-needed strain and stress on the tranny case and engine mounting points. Lets not forget the ghetto vibes that solid mounts give you.

In the interest of explain to folks all the facts around motor mounts, I would be grateful if you would please explain how torque is taken away under load. If the engine moves at all it stops at some point. Lets say 5 mm. heck 10mm of movement, then presumably it stops moving or the engine falls out of the car.So what of torque now? I am sorry but it seems to me this argument is flawed....thanks for your input

thanks i did that and NOWHERE does it show data to indicate that torque is lost in transfer to the ground due to flex in a motor mount so please help here thank you

i keep hearing about prothane and solid mounts.
ive tried solid, my buddies tried the prothane.
ALL caused false knock through almost the entire power band when logged.
Technically, its the mounts causing this due to the stiffness of the compund, but the pcm is still pulling timing and your losing performance, thanks to our lovely sensitive knock sensor
We cured this by going back to the stock hardware or swapping the trans mounts with a softer compound and this helped wheel hop alot!
After testing, logs showed no more false knock and ofcourse tha means timing is not being pulled hence performance was back to where it should be.
Now, other than that, ive never heard of excessive engine movment depleting tq.
This is news to me.
Im not trying to be ignorant or rude, im simply stating what ive been through thus far as far as mounts/wheelhop is concerned.

Aaron you really are an interesting individual. You have no data to support your statements but stand ready to to criticize everyone else even other vendors, for not showing data themselves. I guess you have been found out. I believe that you have shown that you cannot support your claims of lost torque through normal GM OEM power train movement, and so conclude that your claims are not well founded.
Power hop is a separate issue that the video from Jimbo showed the OTTP mounts sure handled that pretty much. As for vibrations, you have indicated your mounts vibrate and your customers either like it or do not.
But frankly any further discussion on this subject will probably be canceled on this forum by the mods as you may need their help.

good post; the issue of pulling spark through vibration is not new, but you have correctly raised the issue in this case as it is pertinent to the discussion. Again the isolation the OTTP mounts provide take care of this. And the rotation takes care of the root cause. And as you are Canadian you lucky guy you can buy from us here in Port perry if you wish cheap shipping and not get strung out by the weak Casnadian dollar.... at least weak this week...

And to be honest that video sounded just like my car does on a launch.
