View Full Version : Anyone intrested in a motor mount alternative?



CougarSE

Over on the www.foxtbirdcougarforums.com we had started a discussion about how hard the stock 5.0 motor plates were to get ahold of. After looking into it and taking some measurements, one of the boards members decided to make a set. Now this guy is what I would call a master fabricator. He has made a similar setup for the TurboCoupe guys and now is intrested in doing some for you SuperCoupe guys. Everyone on the fox board that orderd from him has had nothing but good things to say about the motor mounts. So let me know what you guys think about this, maybe we can get the ball rolling in your favor.

Here are some pics of the mounts he fabed up for our 5.0 foxes. The mn12's I beleive use the same motor mounts as the fox Cougar/Birds. Anything he would build for the SC's would be just this heavy duty.

Is that steel or poly as an isolator? The only concern I would have would be vibration transmision that may interfere with the knock sensor

Not for sure,but I think ares have different
angle on the portion that bolts to the block.

I would be interested in buying a set if they are a direct bolt in for the SC.

Sorry to have put this in the wrong forum, I'm gettin the hang of this forum still.

The isolator is a poly peice. There have been no problems with the knock sensor on the TC's at least.

Yes those in the picture are for a 5.0. I have the set of brackets of my sc 3.8 in the mail on the way to the guy so he can get a prototype designed.

Great! Now hopefully we can get enough people together to get a batch made.

I need to get my spare set of motor mounts out to the guy. I'm not sure how long it will take to get them done. I'll contact him in the morning and find out.

Ok guys, I talked to the fabricator and he says they are gona be around $150. The mounts in the pictures above cost about that. We should have a final price in about two weeks.

I'll definit;y get a set...94-95 are different however..Bracket wise

Chuck W

Hey folks,

Just thought I'd pop in an say hey. Not sure if I'd call myself a "master fabricator", but I am the guy responsible for the mounts shown above. As soon as I get the pieces from CougarSE I'll be better able to determine the final design.
I probably have 150 sets of 6 different type of motor mounts out on cars around the US and Canada (even a couple overseas), and I have no doubt I'll be able to come up with a satisfactory solution should folks be interested.

I'm not going to pimp myself too much and we'll see how things go. Any questions feel free to ask.

Besides the 94-95 brackets being different. What is to prevent this mount from collapsing on itself once the poly wears? Mayeb a welded cup surrounding poly and about 1/4 inch up from bottom of lower bracket?...Just athought

Chuck W
05-17-2006, 02:33 PM
I think there is little chance of the isolator just "collapsing". I had run a set of the isolators on my prototype units on one of my cars for at least 3 years with no issues. There was a minor compression after that time, but I just swapped the isolators side to side. It would take ALOT of force to just smash them.

Where are the 94-95 ones different? I'm assuming it's in the lower portion due to the crossmember change from 5.0 to 4.6 at this time.

XxSlowpokexX
05-17-2006, 11:49 PM
The motor sits lower. One or both of teh bottom brackets are slightly differnt...Maybe someone has soem to send ya? Like I said I'd be interested in a set or two

Chuck W
05-20-2006, 04:51 PM
Where are the knock sensors located? Someone mentioned KS clearance as a possible issue.

05-20-2006, 10:14 PM
It is under the pass side Mount. By under, I guess I need a pic. The mount almost wraps around it.

Chris

Chuck W
05-20-2006, 10:36 PM
Yeah, I guess I would need to see it. Any pics?

Chuck W
05-25-2006, 09:15 PM
Well it might come down to CougarSE not being able to get me the mounts to prototype.

Anyone have a set they want to send/loan me to work from? It would be worth a set of the poly mounts to you if so.

Let me know

Hrmm..well I got the stuff from CougarSE...and he didn't send the entire mount:p

I can probably make due, but I do need the height of the isolator itself. Compressed and free height if possible.

Thanks

:p

I thought you said you had the bottom halfs of the 5.0 mounts... cause they are the same isolator and all.

Chuck W
06-08-2006, 10:48 PM
No I said I could use the bottom half of MY 5.0 mounts....but the stockers that I could have used to compare these with are back with their original owner ;)

If I can get the isolator height I can probably make due with what you sent me.

Chuck W
06-21-2006, 05:33 PM
Well, it looks like I am going to need a set of MN-12 mounts to be able to do this correctly. Anyone have a set they want to loan me?(looking for 89-93 as well as 94-95)

Shoot me an email at chuck@turbochuck.com


Chuck

Chuck W
07-07-2006, 01:03 AM
OK, I have some stockers to work from (89-93), so I should be able to come up with something to suit this application.

I did figure out that the set pictured in this thread (the 5.0 ones) should possibly work for a 5.0 in the 89-93 platform. I can confirm this next time I do more of those as well for any that might be interested.

Still working through it. Been buried under other things.

I'm still waiting to hear back on an installed isolator height from anyone before I finalize things.

Chuck

08-03-2006, 11:18 PM
I would like it to be about a 1/4 inch lower then stock...I will send a MO as soon as you have a set ready for me too.

Chris

Chuck W
08-03-2006, 11:43 PM
Well, I've been trying to get what the "stock" installed height is on the isolator. Unloaded it's about 3"...but what about with the weight of the engine on it?

seawalkersee
08-04-2006, 10:04 AM
How do you want it measured? From bolt hole to engine? Stright up? angle from block surface to subframe? I can get that for you very soon...

Chris

Chuck W
08-04-2006, 10:59 AM
I'm looking for the height of the isolator itself. From where it sits flat on the lower U-bracket to where it sits flat against the upper bracket.

I have a complete set of mounts here....but obviously the isolators aren't loaded.

Randy N Connie
08-04-2006, 11:27 AM
Some thing like this.

seawalkersee
08-07-2006, 07:33 PM
Ok...its kind of a pain in the arse to get that measurement. It is somewhere between 3" and 3 1/8". Im measuring with a tape measure and there is not a lot of room under there to look. I would be HAPPY to try out a set and let you know fit and finish...:D .

What dimentions are you getting? What kind of height difference do you usually see with a loaded mount on a SBF?

Chris

Chuck W
08-07-2006, 10:11 PM
Well it looks like they don't compress much (at least the hydraulic ones).

It give me a direction to pursue though. Just wanted to be certain before I worked out the final details.

Thanks
:D

seawalkersee
08-07-2006, 10:58 PM
I can TRY to get a front measure tomorrow...The bad part is that all the front mount stuff is missing from the engine. I would like a set when they are complete though. Any idea when that will happen?

Chris

Chuck W
08-07-2006, 11:13 PM
Don't worry about it. Your initial try is enough for me.

As far as when, it depends on when I finalize my pieces and get some sample bits from my laser-cutter. I will do a couple sets in my next batch, but the way things are going it might not be until Oct before I'd have any ready. I have a batch of some others I need to get welded up as soon as I get the parts.

Chuck

08-07-2006, 11:21 PM

Sorry, got sidetracked by some other issues.

I still have these sitting on my desk and need to sort out some of the finer details. I'm going to get back on track with these.

These will not work in a Mustang, unless it uses the same mounts as an MN-12....which I doubt it does.

Chuck W
10-12-2006, 07:21 AM
OK, I spent time last night sorting out things and will be sending the drawings off for the laser cut quote and to get a couple samples after that.

As a side note, if any of you guys are 5.0 MN-12 guys as well....I will now have an option for you also.

XxSlowpokexX
10-13-2006, 04:51 PM
Chuck,

Did you ever look at the differences between the earlier SC's an dteh later models? I believe its the 93-95 that sits slightly lower..That may be easily remedied with a shim or something if fit to work on a later model for use in an earlier one

Chuck W
10-13-2006, 05:06 PM
The mounts I have for samples are 89's IIRC. I don't have any info on the differences between them and the later ones.

What do you have ? Need something more rigid than stock mounts for my 93 SC with 5.0 based motor. BTW...can you increase the height of the mounts 1" ? Had to raise mine with spacers for oil pan clearance over the K member.

See the pic at the beginning of this thread. That's is what the 5.0 mounts are going to look like. Those are the Fox ones....but after getting a bunch of pieces here in front of me, the MN-12 stuff is not far removed from the 86-88 Fox stuff.
As far as the height goes. I don't really have that much adjustment in my design, but with a longer bolt and a handful of the top washers you see on top of the isolators, you could raise them up a bit. You might get another 1/2" with the included hardware.

Chuck W
10-18-2006, 08:15 AM
Anyone have the thread size for the hardware that bolts the mounts to the block? I know the size for the big through bolt in the base.

Chuck W
10-25-2006, 11:12 AM
Well from what I can gather, the hardware is M10-1.5 thread. If anyone has any other info please pass it along.

I will be ordering some sample bits here probably by the end of the week for these as well as the 5.0 mounts.

Chuck W
10-26-2006, 02:52 PM
Anyone have a set of the later mounts they'd like to loan me so I can scope out the differences?

If the only difference is in the bases, and the isolator height and upper brackets are the same I'd just need the lowers, or a good comparison by someone on the differences.

Chuck W
10-27-2006, 10:43 AM
OK, well bits are ordered. Hopefully I'll have the pieces in a week or so and get the samples pieced together.

Still looking for some of the later mounts, or even just the lower portion as I understand the rest of the mounts are unchanged dimensionally.

Can someone verify the mount-to-block hardware thread size for me? Is it metric (10mm-1.5) or std (7/16-14)?

Thanks!

Chuck W
11-28-2006, 02:06 PM
Ok, I finally have the parts in hand for these and will be getting the prototypes together over the next week.

I did get the block hardware verified, so that is not an issue.

I'm still looking for a set of the 94-95 mounts to get details on the differences.

Chuck W
11-30-2006, 09:46 PM
Ok, in case anyone is still paying attention....:cool:
Pics of the 89-93 mounts...

I just got the driver side mocked up. The pass is going to be pretty much the same save for the base. These will be jig built.

I will be sending a set off to George D here hopefully before the end of the year. (Need to get them plated and order more bushings). I will probably work up a small group buy on them after the first of the year, but I will have 3 other sets available out of this first group if someone is impatient for them. ;)

I am still working on getting my hands on some later 3.8SC and 4.6 mounts to round out the selection.

In the thread HERE (http://www.sccoa.com/forums/showthread.php?t=84279) I talk more about the SC mounts.

As of right now I should have the 89-92 cars covered for the 3.8 and the 5.0, but I haven't gotten any later mounts to go off of. I know the lower brackets are different between the "early" and "late" cars, but they should be the same across the engine choices. For example, the lower bases are the same between the 3.8 and 5.0 for the 89-92 cars. I'm guessing if I can get some later lower brackets to work from, I can cover "conversion" cars as well.

Anyway, do you have any old mounts?

Purdy.

I would be interested in the height as well. If they can be adjusted, based on the thickness of the lower bushing.

I'm not going to chop up bushings and sleeves for custom heights.

As mentioned in this thread

they are slightly lower than stock.
