Well I just had a chance to drive the car, when it idles you can notice a vibration and while moving at lower rpms you can definitely tell there's vibrations as its slightly louder. Seems to clear up as the rpms rise. Is this similar to those who have these mounts installed?

I have 15 minor mods which each drop a second from quarter mile times. Can't wait to take it to the track. ET should be under zero seconds.

Straight race oriented car/driver, go for it. Dailey driver or weekend cruiser, not so much. I do have them in both my road racer and drag car, but they wouldnt be in my street car. Just my .02

Do these effect how high the engine sits? I have a fast 102 and its very tight. If these raise the engine up some how I dont think my 102 will fit.
Anyone have any experiance with the mounts and 102?

I have a ported FAST 92 intake, and it does not touch the hood liner.

My suggestion....as I experienced everything your considering. While your spending the money on these particular mods...go ahead and rebuild EVERYTHING rebuildable in your torque tube and be done with it. I had a bearing going out and let me tell you.....the Pfadt stuff let me know there was something slightly out of order.

btw - what should i do in the torque tube? Only 395 WHP - road racing not drags or launching much - but the rear assy is on the floor atm.
couplers and bearings?
and btw - never strip your rear fill plug.....

Hey guys! We designed the engine mounts to provide the best response possible while still retaining daily drivability. There is some Noise/Vibration/Harshness absorption designed into those mounts, so please don't confuse them with a solid mount. You definitely will feel the engine transmitting vibrations into the chassis more than the stock liquid filled mounts, but for high horsepower applications or for folks spending time at the drag strip or Autox/Road course, the benefits are absolutely worth the tradeoffs. Mitigating power train shake with the Engine Mounts and the Differential Brace goes a long way to preventing wheel hop which can damage power train components in short order.
Here is a video we prepared illustrating the difference between a car on stock engine mounts, and the same car installation of our engine mounts.

raise / lower
A consideration if you already have a Fast - about raising the engine as stated above..

I have a car here that I am chasing a nasty vibration. Specially over 2000rpms... I am thinking its these mounts....
We have assembled disassembled just about everything on this car except the engine itself.
Car has a nasty vibration. my first thought was the mounts... Talked to pfadt and they said it wasn't the issue. I'm inclined it is.
Changing them tomorrow or the day after.

see above .. I purchased some mounts to lower the engine slightly to give more room for the Fast102 - so it does not touch anymore...
