Torque Solutions (Pfadt) Solid Engine Motor Mounts - Torque Specs?

[demonspeed]

I decided to toss these on as part of my engine build, but my OCD is getting the best of me in that I want to know how tight to actually make the center bolt the aluminum top to the bottom bracket. “Really tight” is where I’m at with them at the moment, but wondering what others have done.

I’ve searched but haven’t seen anything based on the terms I was using. I came across some dead links for the pfadt instructions, so if anyone has those in pdf that we could upload to this thread for posterity that may be helpful as well.

GM service manual says 59ftlb for top and bottom nut for OE mounts, so that’s where I have those, FWIW. I just have this paranoia of the engine rocking back and forth because the center bolts aren’t tight enough

I had looked at these when I was looking for a solid motor mount but decided against it when I saw that the bushing is poly and decided to go with BMRs solid upgrade that uses a billet bushing making it a true solid mount. I am picking the car up tomorrow and will be posting on how they feel, if my teeth don't rattle out first. GL with the Torque Solutions mounts!

The TS mounts only have poly (derlin?) washers which are very thin. It would be as simple as swapping to any hardware store metal washer if one wanted to. There’s really nothing polyurethane about them otherwise - they’re definitely solid mounts.

Nice

For the record, I simply cranked the bolts down Heman-tight. Car feels great even with my big cam. If anyone is concerned with NVH they should stick to driving their couch
