Anyone here have leads on aftermarket motor mounts? I think I remember SirAndy having one made of box chromoly when he was still running a 4-banger. I'm looking for something solid and lighter than the stock bar.

For the rubber mounts I wouldn't run anything but the stock mounts unless it's an all out race car. As for the bar you could fab up a bar that's lighter, but to be strong enough the weight savings would be small.

Yeah, I'm looking for a bar that's lighter than the stock one.

This is for my trailered racecar, you might have seen it before:

Make a pair on the lathe, shouldnt take you more than a half hour (assuming you have a sideshift)

Its been done. I think the weight savings were pretty minimal , as stated above. Seems like it wasn't even a full pound in reduced weight.

I wonder is a T bar would make it lighter. Four tubes for bolt passthrough, flat plate on top parallel to the ground, flat plate vertical.

I bet that would do it, and weight a lot less.

I have a mount bar laying around here. I could whip up a prototype...

McMark that sounds interesting. I'm not sure what you mean though, you're talking about a motor mount like the -6 has?

Also anybody remember SirAndy's motor mount back when he had a type IV?

Ayup, sure is ugly.
Pretty quick tho. 2nd place material.

Why would you want to lighten one of the lowest parts of the car? That will raise your cg.

Here's a mockup design.

How does your design ensure there is no rotational flex, or do you feel this is not an issue? Do you believe this design can meet the stock design of keeping the engine in a very static position?

Eric, rotational stress along the length should occur between the center and the ends. There will never been end to end torsion, because the body is relatively solid (for the purposes of this design study). So you have a 1.75' section that's twisting, which is pretty short. I think the T-structure will provide sufficient strength.

Torsion comparisons between this design and the stock bar would be fairly easy to conduct. Drilling holes would also be an option that could be tested....

Cool

So how much weight do you anticipate saving?

You will need a hole for the shift rod.

BTW, if ya'll want a rematch, it'll be at Packwood WA, August 8 & 9.
Ya'll come to our house & lay a whippin' on us'n & we'll call it even.

I think Andrew remembers this car.

Yeah I remember that second place you got to our first on sunday As I remember it we're already tied (BMWs don't count dammit )

How about a rematch without tire warmers?

I'm not too worried about the CG when the whole car needs to be lighter. By that logic we should be adding lead panels to the floors to lower the CG. Overall weight is a much more important factor right now.

Well the event was cumulative times for 2 days just like the SCCA does at the Nationals, but Andrew did a fine come back on day 2....... but not enuff to make up for the first day's ass kicking.

Sure, no tire warmers and no changing the car for day 2.

Brit's unfortunate cones after the lights on his last run let both you'z guys and the Beemer thru on day 2. We did OK for our first time on concrete *at your house*.

I like that design, but the car still has a sideshifter and typical linkage. I'll have to take some measurements of the hole in the stock motor mount.

Clearance for the shifter wouldn't be too big of a deal. I'm searching for appropriate 'tubes' for the bolts to pass through.

Do you guys even shift that car at all? It seems, all you would need is 2nd gear.

Throw away the shifter and linkage and remove all unneeded gears from the tranny ...

PS: Do you still have the steel targa bar?

I like the idea of a six-like mount for a TIV that was mentioned before.
Should be small and slick design once the front fan housing is removed (which it is on this 914 last I looked).
Trying something new is cool

Yeah we have the steel targa bar, but we aren't cutting out pieces of the structure of the car, it already flexes enough as it is.

If I remember correctly you had a tubular steel motor mount in your car at one point, do you still have it or any pictures?

I looked for pics but i couldn't find any.

I trashed it after a week or so and went back to the stock bar ...

Here is Paul Woodbury's (URY914) engine bar...love the wheels....

I like that. Are there more pictures around?
