Upgrading engine mounts?

It seems like these engines have a ton of play in them. When I test drove my car before I bought it, the engine rotation actually popped the intake tube off the airbox. Anyone going to different / stiffer engine mounts on their TVS car?

Pfadt has solid engine mounts

Are solid mounts recommended for this application?

Don't know what application you're going for but yes, solid engine mounts will get rid of pretty much all engine movement. Though it will also increase road noise as well.

Just the stock ZL575. I couldn't believe how much rotation of the engine occurred in these cars between on and off throttle.

Im sure someone makes one, but solid mounts can be brutal to live with. Race car stuff. Pfadts is a very small self lubing bushing in a rigid aluminum frame. 95% of the character of solid, but much, much less stress/vibration. The best compromise out there.

Prothane makes a nice poly pancake mount, too. Its a little more affordable then the pfadt, but a different style.

Theres a third company that makes a direct copy (imo) of the pfadt mount for a few bucks less. Jury's still out on that one. They claim 7 second tested but no one has a camaro nearly that fast. http://www.torquesolution.com/product-p/ts-cam-001.htm

So you would recommend the pfadt mount for a TVS blown motor then?

Its not necessary, unless youre having issues with piping due to engine movement. I run the pfadt style mount because of tight tolerance in the fit of the 4l80. The prothane mounts are a little more compliant if you dont want any extra vibes in the car

After a while I can't even tell I have the Pfadt mounts. They started off almost unbearable, but either I got use to them or they softened up. But from vids of my engine from dyno pulls the engine doesn't move at all.

I have maggie car. They would be a good addition although I have no problems except my car is cammed and when the engine is first started and warming up I do here some pipe clinging from the engine movement but once its warm and smooth out I dont here it; niether do I hear it when i punch the gas. I will probably get them though when I do my 416ci block.

I had the Prothane motor mounts installed at Jannetty's. Cammed with blower 680 to the wheels had a lot of engine movement, but not anymore. Vibration did increase, but is not annoying. Nice product... Glad I had them installed.

Yeah, after being installed for a bit, they will loosen up a little more. Plus you probably got used to them more.


Really they aren't very bad, they do increase noise and vibration a little, but the benefits far outway this. They use graphite-impregnated polyurethane bushings for long life and performance.
They give the engine excellent mounting, won't allow it to rock back and forth which may cause hood interference, or damage to other parts. If you have a cam, they will actually cause the car to shake a little less (more mass for the engine to shake). They will also actually improve throttle and power response, since the engine doesn't use power and time to twist the engine until the stock mounts hold it back. If you have a cam and/or make big power, these are a must IMO.

With our free shipping, the Pfadt Engine Mounts cost about the same as those fake Pfadt mounts, plus they look much better, and you get an actual quality part!

Thanks MJ I was wondering how you liked them.

These are Really Beefy Units, Well thought out and Minimal Vibration from our experience.

I just installed the Pfadt engine mounts about 9 days ago... You feel it a decent amount right away but they settle in and now I barely have any movement/noise that I recognize..mainly it's just the start in 1st gear that I can still feel it... definitely worth the upgrade to stop the engine play that the stock mounts have, as well as saving some weight from those huge ass OEM mounts!

Is it necessary to add the Polyurethane tranny mount with the motor mounts?

Necessary no... Recommended, yes... The primary reason to add more solid mounts is to limit drivetrain movement so power is transferred... As well as limit movement if piping is in close quarters.

Why not add the trans mount... It's inexpensive, and easy to do...I use the prothane motor mounts, and modified a urethane trans mount to work on my car... But my trans cross member and trans are one off pieces...

Same here. Pfadt ones work great and the solid mounts are bearable

Thanks for the info on the tranny mounts guys. How much more hp do you think the mounts help put down at the rear wheels? I'm guessing something insignificant, like 2-3hp?
