Just as the title said, i hear from a few people that you can run both, and others say you can't. Using what i learned in my engineering classes, logically i feel like they both shouldnt work together. If the solid engine mount keeps the drivetrain in the same position and the rotated mount changes the orientation by 17 degrees, i feel like they shouldnt work together. The thing is I read that alot of people run both. I ordered the ottp rotated trans mount and plan on buying the ttr solid engine mount if they are compatible together. Any Input would be greatly appreciated

 

sounds like a recipie for fillings faling out of your mouth.

 

From what I know you can, the thing with the solid upper mount, they metal is just a different metal and is stronger then stock. The polyurethane that is in mount is still flexible enough to allow for motor movement and for the pitch of the engine to change. With the different polyurethane, they are rigid, yet flexible. The bushing will last a lot longer then stock and is just more packed together then the stock rubber bushing.

 

I ran the OTTP rotated trans mounts when they were made by John Powell. John recommended running the stock engine mount with them. He can explain why better than I can. But basically the engine has to be able to flex at some point. If there is no room for movement, you are going to start breaking things...........

 

Thanks for the response and the info. I think i will stick with just the trans mounts, at least for now. If the trans mount is stiffer it should be enough to remove/limit the movement, even with the stock motor mount. If anyone else has any information feel free to chime in

 

mod is correct. the rotation has to happen and the stock upper pass side mount has large holes which enable the rotation... good choice op. enjoy your ride.

 

Thanks a lot for the info. Why is it then that some vendors recommend both? Is it just to get the sale?

 

That vendor can explain this to you because I am not familiar with his mounts and how they work with a solid engine mount.

 

This is true; Right on actually.

Also Shawn the rotation is not even close to 17 degrees (That is almost half of a 45 degrees). It is MAYBE 1.7 degrees, if that. The rotated tranny mounts move at a MAX of ~.5" in any one direction.

 

I have zzp's rotated mounts and turbo techs upper engine mount. I get a lot of vibration at lower Rpms. So what I'm reading here is that the stock upper engine mount is best with rotated mounts.

 

im running zzp rotated tranny mounts, front and rear with their upper engine mount. love it! other than the vibes but its worth it.

 

Yeah I know its an old thread, but can anyone explain why a solid mount and rotated mounts would break things?

I have ottp stage 2 moints and a zzp solid engine mount. I wana make sure that I dont break anything.

 

Think of how the rotated mounts move the engine up and forward. The stock mount allows for a bit of flex which works perfect for rotated mounts. With a solid mount, it is designed to keep the motor in the stock location very firmly and not flex like the stock one would.

 

So because the solid engine mount dosent flex it will break my motor or trans?

 

In my opinion, it would break at the weakest link. The mounts or where they're attached.

 

Yeah I see the point now. The rotation causes more stress on the engine mount.

Now I got to uninstall my engine mount lol.

 

Good thing i found this thread lol i got stg2 ottp mounts and was thinking of getting the zzp engine mount i guess im not anymore lol

 

I wonder if this would be best suited to run an engine damper with rotated mounts, if people want to run two mounts together. After all, the damper allows movement.

 

Good thing I found this thread... I don't have any mounts but wanted some. So all I need is the stage 2 rotated trans mounts to stop wheel hop?

I run stage 2 ottp mounts with the OEM tam and Ingalls. Combo is ****!
Good 20k on it and no Issues. Just adjust it right.

 

How do you adjust the ottp mounts?

 

He's talking about the ingalls...

I wouldnt run the ingalls with a rotated mount, and if you read up a few posts you will understand why. BlackSSs2 didnt have any issues, but due to the fact the ingalls is designed to limit movement of the stock upper engine mount it isnt ideal.

I removed my ingalls when I installed my powell rotated mount, and it was a nice upgrade indeed.

 

Ingalls dampens that movement with the idea of getting that power to the drive line instead.

 

Yes, it dampens, but it still limits the movement some... I spoke to powell about this back in the day when I still had the ingalls.

By itself it's fine for a lightly modifed car.

But once you install the rotated mount it is not needed.

 

Are stage 2 Ottp rotated mounts all I need to stop wheel hop? No engine mount?
