I would guess that if they just mimicked the shape of the steel mounts it's probably not going to be very ideal. you can't just take the same shape without considering the different properties of the two metals...

yeah i still keep in touch with my material science nerdy friend from UC Berkeley... He knows a lot about this shit and could probably tell us all the correct answer. However, we wouldn't know what the hell he said :rofl:

 

Aluminum is weaker in tensile strength. It's also almost only 1 quarter strength of the type of steel they'd typically use, wrt shear. I don't know how motor mounts work exactly, but if I were to guess I don't think the strength of the metal used would be much of a problem since the motor generally moves up and down when it torques. There are side ways componants to the action, but it's nothing aluminum couldn't handle. I think the metal cuffs are more there to prevent the polyurethane from translating sideways and favoring one side, which would cause premature wear.

They probably also prevent the polyurethane from getting squished.

 

Yeah, these are machined. If they were cast, they'd be weaker... (short answer)

 

short answer = perfectly fine with me

 

So now that your answer has contradicted itself several times and the short answer doesn't match your long answer let me ask this for an answer without the geek speak.....

Has anyone heard of these mount brackets or know anyone who has used them?

If you do not do you think there would be an inherent structural flaw in the way it was made, materials used, or general BS?

Thanks...English laymans responses are best appreciated.

 

one of the strongest way to make aluminum parts is to CNC is from a billet which is what they claim.

I for one would not use them in but I'm always on the side of caution

 

How am I contradicting myself? If you'd like I can quote my text books.

geek speak = mechanical engineering speak? (guys who build cars, and hopefully designed these parts?)

Someone asked for tensile strength, so, I gave them tensile strength AND shear strength, because it's probably more relevant here.

 

i was doing some searching yesterday and i came accross those mounts on honda-tech, i might be getting an 88 hatch on friday and was actually gonna get those exact same mounts. several people said that the mounts were pretty good, (on h-t) and on az race and machines' website they are listed at 325 so thats not bad for billet mounts.

 

probably okay mounts, but i wouldn't try anything other than oem or Hasport on fit.

my friends place racing mount. ****in' junk. no where close to oem fit. my hasport mounts that i had. oem like fit, great finish and quality.

those may be strong. Oem fit, doubtful.

 

I don't see why they would not be strong alot of aftermarket mounts are billet h: EX. Hasport, Place racing.
