So I've read a bit about the hockey puck / solid mount on the 00+ cars to reduce torque movement in the engine.

My question is, how does it reduce this torque movement? Is it taller than the (compressed?) stock mount, so that the engine is effectively held in a "pre-torqued" position?

the stock mount allows some movement when the go pedal is pushed. I believe it is softer for less vibration and smoother operation.

the hockey puck mount is bolted all the way through, so the engine can't really move when you stomp on the go pedal, and thus transfers all the power to the wheels, instead of some to lifting up the engine

the stock mount has rubber between the bolts that expands and compresses when you hit the gas in drive or reverse. this makes for quieter smoother operation, but is also a weak point.

Ah, OK, I gotcha...the stock mount is effectively two separate bolts, with "flexible stuff" between them. The modded mount is basically a giant swaybar endlink kit, then.

Now I can see why there would be additional vibrational transfer into the frame when going with the one-piece through-bolt...I wonder if it could be constructed with a small-diameter plastic, vinyl, rubber or poly sleeve / bushing where the bolt goes through the frame, to reduce this transfer...

not sure on that one, but I am sure other people with more knowledge then me will chime in sooner or later

The stock is probably oil filled as well.

I've seen a few in cars that were varying mileage. It is a sad excuse for a mount. The motor moves 3-4 inches in my experience.

I thought about adding something to absorb some of the vibration..however didn't find any vibration when I did ti to mine.

I replaced my stock mount after finding a small amount of oil on the garage floor. The most important thing is to fab the new mount the same height as the stock mount.

After the mod, i do feel a slight vibration at around 1,400--1,800 RPM. But it is nothing that really bothers me at all. But the overall feeling of more power being put to the wheels easily puts a smile on my face.

i had and still have the first solid mount for the 2000+ SSEi . i have over 120,000 miles on mine with no problems (so far). the distance between the top of the BOTTOM cross member and the bottom of the TOP motor mount bracket is 3 5/8" that is how high your new mount should be when it is tight. i made a 2 1/2" wide motor mount for a friend out of an old tire. we used a 2 1/2" hole saw and cut holes (wafers) out of the sidewall of an old truck tire. cost for his solid mount $0.00 and he has over 40,000 miles with out any problems.

Everytime Rod posts that story it kills me...

Rod..we don't all have old tires laying around..lol

OMG i got the tire we used for Tom'* car on the side of the freeway .....haaa......haaa.....haaa

My question is what happens during winter when it gets very cold, does the modded mount become noisier due to colder temps. I live in Canada and the winters here are brutal. :(
