So why are folks using hockey pucks for motor mounts? I see they do work, but being a car guy I would be embarrassed if someone saw that in my car's engine.

Here is my thought.

I used to work at Grainger Industrial Supply and what I always saw in an industrial setting were vibration isolators for heavy machinery.

Wouldn't you want something with a specific application and possibly even heat resistant?

Something like this?

Applications:
Used in all applications, running machines, auto machine, home appliance, especially for automobiles and motorcycles ,dampen vibration; prolong machine life, good rigidity and protection

The hockey pucks are simply used as a spacer, and really they don't look bad, at least not enough to worry about on anything but an all out show car... which there are maybe five of those out there total, if that.

Often times those vibration isolators are used for compression, the tension applied by the engine under full throttle would rip it apart just like the stock mount if not easier. Vibration caused by large machinery is very different then that caused by a car engine, they are more worried about the banging and heavy hitting that over time can cause stress and damage so those isolators are usually quite rigid, using one would likely result in the same vibration caused by the hockey puck mount, which actually is not bad at all with a small sway bar end link isolator on the top side.

Show me a mount like you posted that isn't 10x-20x more expensive than a hockey puck mount and I'll be interested.

It's the cost/benefit of it. The hockey puck mount is under $20, if done right doesn't vibrate any more than the stock mount, but plants the power like a solid mount. It's the best of all worlds, and no one ever asked me about it, really.

well atleast i know why im getting tge vibrations i put the sway link bushing on the wrong side, but back to the matter at hand you could always use andrews second idea from the boat store it gives you the same durabilitt as the hocku pucks with a predrilled hole and a singular piece instead of the three pucks which in my opion gives you a better look with a single piece and futher more as far as a show car goes who looks at the engine bay and goes aw man that not an original motor mount i know whenever i see a show cars engine my eye is not looking for motor mount consisty

Mickey Mouse? Try inventive, especially due to the low cost involved. As long as you have the tools you can make the mount look just as nice with hockey pucks. As mentioned, I don't envision Grainger being able to beat the cost especially with shipping costs involved.

The pucks are cheap and effective. The only thing that sucks is the vibes, even with the bushing underneath. It may not be bad for some, but it bothered me personally. I'm back on a stock mount right now, and good God the power delivery is awful. Feels like the motor is attached to the car with a rubber band. Hopefully the Anchor mount will survive the winter.

Boat roller is in the works.

but being a car guy I would be embarrassed if someone saw that in my car's engine.

Have you seen my car?


Has anyone tried just stacking up a bunch of polyurethane sway bar bushings? Those are softer than the hockey pucks. You would think that an extra 1-2 bushings above and below the pucks should also reduce any vibration. I don't think the boat roller would be any softer than the hockey puck, but depends on the roller.

Looking through ES poly stuff, here are a few things I would think could work a little better (but cost more than hockey pucks) from a 'car guy' perspective:
9.9005
9.8108

You guys are correct, cheap is subjective as well as looks. Cost is objective, so I will go with that. Yes the cost is less than all other options. However, I priced the factory GM mount at $140 msrp. My Hasport motor mounts for my 92 civic was over $500. That was pricey. I would be willing to pay up to $200 if someone built a motor mount that last. The only reason I see going to the hockey puck is because it works.

One thing I have noticed going from hondas to pontiacs is parts supports or lack there of. Does someone like Prothane or Energy Suspension make a mount?

Pics of my Hasport mounts and what my mind is thinking of.

I couldn't do hockey pucks either. I went with this and a washer.

Mods,

This may turn into a chat/brainstorming thread. Can you please move?

Thanks

There is no aftermarket alternative that will bolt on to our cars that provides any improvement over stock, not for performance or durability.

Well the parts support problem is that you have a bonneville. It is a big old grandma car to most people and probably 80% of modded ones are on this forum. Compare that to a civic that every high school kid can afford and mod and you have your answer, the demand simply isn't there.

So what is up with these mounts? Is this possible? I have seen several versions with upper engine mounts (Regal, Grand Prix)

That was just what GM decided to use on the W body cars, not 100% sure why but I would assume a difference in the subframe design, meaning the W body doesn't have room for mounts like the bonneville or these mounts were cheaper to manufacture and install (would be my guess). they can be adapted, I know 2003SSEi put one on his, though I believe it was just because no real performance reason. FYI the bonneville platform is the H body, It has a lot different from the more common Grand prixs and regals with the same engine. Most of what we do to the bonnevilles is custom, just because It may be plug and play on a Grand Prix doesn't mean it is on a bonneville. You will need to think outside the box for the bonneville for most if not all mods.

As far as adapting this mount to the bonneville it wouldn't be wise to replace the lower mount for this, this style mount won't hold the engine up and IMO you would get a lot more engine movement from it.

I'm thinking of using all 3 in the front. 2 up top and the oe one on the bottom.

Found it!

Looks like the engine part just bolts on. He did some work to the body support though.

Yes the engine side bracket just bolts to the head. The body side was all welded together and i believe the stock support bar went over the piece he made. Not 100% sure though he may chime in about it though.

I hope so. Wonder if he thinks the fab support was necessary. If not, it would be really close to 100% bolt on.
