So what you're saying is, Supras owners aren't as smart as Z owners huh? Second question... Why would you charge the same price on a motor mounts that are entirely different from the Supra mounts? It's because you can right?


Because there is NOTHING I HATE MORE than a company that slaps $20 worth of parts together and tries to sell it to that public for a million dollars. It's like your taking advantage of the same people you're claiming to support. To me it's unethical and shameful.
Futhermore I'd like to state that I think solid motor mounts are all together a bad idea. You made a statement earlier "I don't believe in using a bolt size other than what Nissan has spent millions of dollars they designed for their cars." How about we expand on that just a bit... Please can you tell our member why Nissan Engineers would spend more money developing rubber motor mounts in our cars if they could have spent far less making solid mounts in the first place? Hell... They could have just bolted the motor directly to the frame if they wanted to come to think of it. Yeah... I suppose they could have done that huh? Why you suppose they didn't?
Please... Can you tell me why NISMO makes their motors from harder rubber or urathane and not from solid metal? I guess their a bunch of idiots too huh? Did you know that motor mounts in todays cars serve other purposes other than "holding the engine up"? They serve as a very important safety feature designed to allow the motor to break away in a frontend impact. It would be a shame to know you where overcharging for a part that might end up costing someone their life huh? I hope you've attached a nice little disclaimer with the sale of evey one of these so called motor mounts you've sold. Just a thought.
Here's another little bit of information I'm gonna share witcha... The same "shock energy" from the motor that you're trying to isolate with your motor mounts is going to go somewhere... perhaps you'll sell an expensive fix for that to. Again... This is just the opinion of a lowly consumer. Don't mind me a bit.



You hate me now huh?

 

so i take it you don't think the force of a crash would sheer the bolt stud on the solid motor mounts or break the mount from the body?

I suppose intercoolers and turbos are hurting crash tests as well

 

Supra owners are not as smart as Z owners? Come on that is a rediculous statement. I am not taking advantage of anyone. These cost us well more than $20 to make and well more than the other ones on the market. Why do I sell them for the same as the Supra ones? Because they cost the same to produce. They are the same design just altered to fit the Nissan 350z. Nissan motor mounts use rubber bushings as they are intended for a comfortable ride with 287hp and 274ft/lbs of torque. Go make 780rwhp and you will see how much the stock motor rotates towards the passenger shock tower. I understand you do not like our motor mounts. It is amusing that you don't say the same as the other mounts on the market Other mounts require the bolt to go through the bottom of the mount. If the top nut loosens and comes off, where does the motor go? You are attacking me personally at this point and not our product. Your statements have been expressed and I don't think there is much else for you to say.

No, I don't hate you. I think your attacks at me personally are a bit far. I would like everyone to understand the pros and cons for a solid motor mount as it is not intended for everyone. I am never here to take advantage of any customer. You can ask anyone that I have done business with in the past. These mounts cost us a lot of money to produce, more so then others, so they have a higher price. I am not getting rich off this design or anything else we are producing and selling.

 

everyone needs to relax, there not gonna sell many/any so don't worry about it.

 

Comon Sentry... I know you understand what I'm talking about. Chances are it would but would you want to take that chance?

 

yeah the bickering over quality etc is getting old

let the consumer make the choice. Glad there's another option, and hope whoever buys them thinks they're worth the price

everyone kinda skipped over my engine balance question/comments/theory and kept bickering instead

the crashtesting is something new I've never considered with solid motor mounts. I tend to think the engine would bend backwards twisting on the engine mounting points if one side doesn't sheer off. It probably is less safe than the stock rubber ones, but I don't think it's a show stopper issue. I mean there's guys removing their airbags and using 4 pt harnesses on the street on unapproved harness bars. Or guys putting in carbon doors with roll cages on the street.

 

so - does anyone know of any stock mounts breaking?

 

i think you brought up a good point, but I already took the chance since I have SVR mounts on my car and have been extremely happy with them

some people think the mounts would punch a hole in the aluminum engine block in an impact

 

As far as engine balancing goes, race cars (mostly drag cars from my experience) use solid motor mounts. Engine dynos use solid motor mounts. I understand you theory on rubber mounts taking the cushion but don't think a solid motor mount would cause more wear on the internals of an engine. Just my thoughts.

 

Come one guys take it easy .... all of this because of an engine mount!!!

 

That's a good point too. But think about it like this...
The Nissan Engineers and designers did infact do a lot of crash testing on our cars. There were some benifits that came out of it. taks for instants the carbon fiber drive shaft that comes stock on all our cars. It was designed to shatter in a front end impact allowing the motor to break away from the motor mounts thus allowing the motor to drop out of the bottom of the car. While that CF drive shaft (due to it's lighter weight) give some performace benefits it was put there with safety in mind first.
I believe that the motor mount design are just as important as a seatbelt or an airbag in that case. It was designed to serve multiple functions to a greater good.

 

This is a really good question that could use an answer. Why not polyurethane?

 

no that's just it, even though the rubber mounts would absorb the energy, the internals are still moving sideways inside the engine

with the solid mounts, there is no sideways energy because the engine can't move, and it gets channeled down the driveshaft instead turning it harder and therefore the engine internals never have to experience lateral forces just from reving your engine

 

too bad the G35 doesn't have a carbon fiber driveshaft though.

yeah I'm sure they did a lot of testing. I think it's probably the overall everything why they chose to go with rubber mounts - no vibration and probably a little better at crashes. They know that their target market are mainly people who like how the car looks and drives and not crazy people like us who want to put forced induction and roll cages on it

 

i use nylock nuts on the bolts we use, so even if the bolt could possibly loosen up, it would never be able to unscrew more by itself. no need to worry there. but as sentry was saying, with people removing their front bumper beams to fit the greddy tt kit (including myself, lol) sometimes form can outway function. i made my mounts for the main reason of satisfiying road racers and drag racers, where possibly other safety devices have been incorporated. i personally love to run solid mounts on the street, and always have, because i love the feel of them. more solid drivetrain responce, and more solid clutch feel.
with the driveline still being able to shatter, i would highly doubt the aluminum block mounts to stay in one piece, and the motor to shove under the car as designed.

 

LOL Right.

 

Wow. Two different products for the same ultimate purpose, one priced more than the other. Both seem to get the job done. Let it go already, all the possible points have been made and scored.

 

Okay MOM.... Geez.

 

Hahaha. Thought I would do something out of character as it is usally me who is ranting and raving.

 

yep.
