I just bought a set of the crappy Anchor mounts for the Dart.

Ok so do we have a price and phone number? I need to get the mounts respooled in the race Duster for Cinda before the season really gets started.

Just had e-mail from Johnny, the maker of the mount. Price is $29 for the parts to do one mount (two halves and a sleeve). Since Ceej has put his set into a race car, he'd like to have a street-driven test car as well. First shoutback to me (send me a PM with name, address, and detailed description of your car) becomes that tester.

hi dan i would be more than happy to give them a try. in ether my stock 75 dart for door or my 73 dart swinger with mild build up slant. address is in your pm

Best I could do with the tools available. I'll get some sound levels. Keep in mind I have a noisy car.

We may have to rely on my subjective input.

CJ

OK. I told you my car was noisy.

Idle runs 86db

35 mph cruising 94db

60 mph cruising 90db

Windows were up. Like that matters...

WOT being an idiot, (No Offense DI) 99db until the cam peaks, then around 103db. Louder than.. .. I don't think we're going to be able to tell anything in sound levels with my car.

On the bright side, the patrol officer passed me after I'd done something stupid with the G-Tech engaged on a back road....

Interesting results, but...does it sound/feel any different/better/worse with the new mounts than with the old?

That was the baseline. I haven't installed the new bushing.

I was busy removing scads of weight from the car this morning. No changes other than the bushing will be made until the test is over.

Tomorrow I plan to swap to the Poly and take the readings again.

I'd be willing to bet we won't be able to tell any difference in sound levels.
All I can hear is the intake and exhaust on this car, reverberating through to a passenger compartment devoid of most creature comforts!

CJ

Once I get my next engine in I'll bug Johnny for a set and see how they do since I'll be driving the duster to work... I'll be changing the BV over to a 1973+ K-member anyway so that may be a 'test bed' in the farther future as well...

-D.Idiot

OK, here we go.

Idle/Neutral
Engine side of mount: .3"/Sec
Frame side of mount: .12"/sec

2000RPM/Neutral
Engine side of mount: .26"/Sec
Frame side of mount: .12"/sec

Idle/In Gear
Engine side of mount: .6"/Sec
Frame side of mount: .3"/sec

1500RPM/In Gear
Engine side of mount: .4"/Sec
Frame side of mount: .15"/sec

This bushing will transfer three or more times the vibration that the stock type bushing will. It's still doing very well.

Off for a road test with the sound level meter. If there's any difference, I would be very surprised.

Yup. It's a noisy car.

97db at 35 mph cruise

97db at 60 cruise

We saw 110db max in the rear seat area. Perhaps I should have put the seat back in. All you can hear is the Dual Dutras blasting out the XLerator 2-1/4" to the bumper.

Soooo, we will not have much to report till somebody with seats, headliners and stuff tries it out. It's just a tad noisier. Subjectively, not so much.

Feel is just a touch more firm. No serious issues. Shift points are firm, but they were before. The car is just violent enough that I can't quantify it.

I think the part will work out just fine for most people. If your looking for a dead silent, smooth as silk shift and so forth for spreading Grey Poupon on your club crackers, perhaps they can use a softer variety of Poly for that mount.

Here are the pics of the spool mount after Ceej and I replaced it.

Before:





Comparison of the two..



Poly Mount installed...





I apologize for those with Dial-Up, it may take awhile for the page to load.

Getting the old mount was cake... installing the poly mount was a bit of a pain. The poly material is much wider on that mount than the original rubber, so to get it down into the k-frame was a bit of a chore. After that, we had a little issue getting the mount to line up correctly on the block, but after about 45 min we had the old one out, and the new one in.

Readings we got are above obviously. I noticed right off the bat that interior vibration was increased, and based on my previous experience with the car, it was by quite a bit. Stuff was actually vibrating...

After we got the car on the road, there really wasn't much of a difference between the poly and the standard rubber. The Poly material really didn't seem to care much about the heat from the exhaust, so all is good to go!

Enjoy!

I wonder if we want to have Johnny reduce the thickness of the exterior flanges?

That would help with ease of installation.

It would only need to be a small change.
How would this effect fore and aft motion in the mount? I think it would be negligible, but that would be a question for the experts.

You may also want to see if he can utilize a softer material for the bushing itself. The inner sleeve may need to be modified for softer materials so it doesn't tear up the bushing. Questions for an engineer with some background in loading and wear properties of these materials.

The Poly bushing on the front motor mount of my 3 banger metro is nearly the consistency of silly putty. A three cylinder can really dance about, as you might well imagine. It is a similar type of mount, and seems to live quite a while.

Back to the slant six poly mount.
At peak transmittance, half of the vibration read as velocity made it through to the frame. That's a marked increase. In my application, having a stiffer mount is desireable. Driving from coast to coast, it would likely be tiresome.

After we finished working on the econoboxes last night I went to pull the Valiant back into the driveway. It was then that I really noticed the harshness transmitted to the steering wheel. It's definitely a noticeable change.
On the bright side, the car "Feels" more menacing. Kind of the same sort of feel one gets from a common pin V-Twin. "It shakes more, so it must be more powerful" kind of feeling.

I will wait 'till I have some run time on this bushing, and take the readings again. I won't be driving the car until I've wrapped the head pipes, so this data will be delayed a bit.
