OEM /6 mount, Mad Dog Options

[Superhawk996]

(IMG:style_emoticons/default/agree.gif)

I was just going to fabricate my own plates for the 914/6 mount and source the fastener. Not really a big deal.

I totally get why the Wevo mount was the original plan when the 914/6 mount wasn't being reproduced.

@mb911 if you fab them, I'm 1st in line

It's great to have an engineers confirmation ! Thank you Superhawk996

The skill for fabricating the chassis part and the engine part is obvious.
Are the two plates to complete the set too much to ask ?
Am I foolish for asking ?

I think mcmark/maddog used and adaptor with the wevo mount because a couple years ago, the oem mounts were not being made, at least not at reasonable pricing. Now uro and porsche have the mounts available as low as $120. It looks like it would be pretty easy to reproduce the two mount plates and like superhawk, I'd like to use the oem rubber mount.

Those plates would be awesome. If I had samples I would have. Bunch made.

Rory ?

Hi Guys, with the help of Luke M, we think we will have a viable design to replicate the bottom and top plates that you are discussing....more to follow soon.

Awesome!

I saw this on ebay.

No doubt from my perspective,

This board ROCKS

thanks to all

Well, that was motivation enough to get me to stop procrastinating and actually order the URO mount. (IMG:style_emoticons/default/aktion035.gif)

Thanks

[maddog]

Hopefully I can have prototypes to Luke sometime next week so he can compare them to his original top and bottom plates...stay tuned

Just an FYI for those who are gonna shop around for the URO engine mount. There's two styles, one is org style rubber and the other is heavy duty.

Part #'s : 914 375 049 00 and 914 375 049 00 HD


I have both on hand but have not used either one just yet.

Hey thanks for posting the pics of your weld. This is invaluable. I should be starting mine relatively soon and have the same mount.

Now, I currently have the Wevo setup sitting with the mount, I wonder if I should abandon it for the OEM style.

If you'd rather have originals on hand to work from I'm willing to lend them
with your guarantee they be returned.
But....maybe I should know your name first !
PM me and we can work out the details

Can always swap it later . Ben posted elsewhere that he was pretty happy with it and that he had set up his car for comfort ride rather than as a track car.

I'm just very picky. The downside of my job is that I used to get paid to do NVH work. Once you learn how to hear and feel some things in tuning a car, you can't un-hear or un-feel them.

I'm the guy that can point out a squeek, or high pitched whistle you've never heard. Or maybe that low frequency vibration you thought was the road . . . but really isn't. From that point on, you'll hear or feel it daily and then it'll drive you mad. I've learned to never point out such things in my friends and family's cars!

Here is what Im thinking for the bottm plate?

Here is what Im thinking for the bottm plate?

@maddog

Looks pretty good.

Assumed constraints on my part based on what I see:
laser / plasma cut
Welded at seams

Need to be thick enough gauge to avoid "blowout" when the snubbers engage.

From previous picture posted I think this one is showing minor signs of heavy snubbing somwhere in it's past. Not a big deal but would be nice to proactively address it. Still totally functional as-is.



I was figuring I'd machine them as one-off but I totally get sheetmetal weldment is the way to go to keep price resonable and to match OEM look. Woundn't have any hesitation about your proposal as long as it is as thick as OEM or a tad more.

Have you considered Titanium? . . . . (IMG:style_emoticons/default/aktion035.gif) Just kidding.

[maddog]

Hawk, I think the thickness of the bottom plate is about 2.5 mm(.098"), Im going with 12 ga steel which is about .105" thick?

Overall I'd say that is great and pretty comparable.

The 0.007" inch won't net much in terms of increase in stiffness or durability of the snubber. The shape has more to do with stiffness than the slight add of thickness.

Might 11 gauge (0.125") work and/or might be cheaper and easier to obtain?

The downside is don't have parts in front of me to know if that thickness add of another 0.020" causes other problems as part of the overall sytem. I don't think so. I'd rather have a stiffer snubber than one that deflects.

Just my $.02...

This is a great project, and I think it is great for any small six. But I have seen a factory six with a Euro 3.2 in it, and the mount was damaged from the extra torque. We pulled the motor, stop drilled the cracks, and welded in reinforcement to keep it from tearing more. The Porsche engineers who designed this mount were not anticipating something like a 3.6L engine when they built it. So I would use something like this in a six conversion for a small six, up to maybe 3.0L. Anything bigger and I would put in a Rich Johnson mount, or a NaroEscape mount. Using two mount points instead of one is better for high horsepower cars.

Solid advice. In my case I'm putting in a 2.4L No issues.

When you start puting big motors in - you're on your own. Motor mount, transmission, axles, brakes, suspension pick up points, etc. All need to be addressed as a system.

Typical hot rod flaw is to just plop a big motor in and think you're done and that you've actually improved the vehicle.

A little wisdom, experience goes a long way in this case. I would bet the engineers in Stuggart knew how much power their engine mount would accommodate and did not plan on 4 liter beast engines. Some guys are cranking 300+ hp and asking an OEM style mount to hold together. I was considering using a two point mount, but went with the Mad Dog unit. Our 914/6 build will not be abused and never see the track
