Just test drove 2013... loud bang

[IWannaGoFast]

I am looking to buy a new Speed3 so I went down to the local dealership and test drove a brand new 2013. During my test drive I turned off traction control and popped the clutch going into 2nd (expecting the tires to break loose or at least chirp) to my surprise I heard a really loud noise that honestly sounded like the tranny dropping out or a motor mount missing and the engine knocking around. I am coming from the turbo sr20 scene and have never experienced anything like this. Is there something wrong with this car I test drove or is this something common on the Speed3?

[mingenyx]

must be defective. should have searched eh?

[beachshoer]

Weak Rear Motor Mount means turbo hits firewall. Nothing new. Buy car. Spend $90 on JBR dogbone. Harness torque.

Problem Solved

[Snotrocket]

sure it wasnt wheel hop?

[bryansawiseone]

Like mentioned above... Buy new RMM and gurantee problem will disappear...

[Keko]

Like they said, RMM. It will also lessen torque steer if you're one of those guys.

Get it

[robry]

where did you test drive it at, so we know not to buy that one....

[vlp123]

i have a 2013 speed3 and no bang?

you don't drive your car hard enough, gramps

[Stingray69]

You guys are going soft on OP. This has to be the easiest thing to find about this car. If he couldn't find this info it is going to be a painful existence around here.

I test drove it at a Mazda dealership in Duluth, GA.

Positive... sounded like the engine fell out of the car.

I can see just about every forum on the internet is now littered with search nazis. I would have searched had I not thought this was an isolated incident. Typically car's don't roll of the line with something as silly as a weak motor mount that would cause a turbo to slam into the firewall.

I don't think i like your smartass tone when asking for help on a problem that is actually extremely common in these cars. THIS site has search nazi's because it is run by OUR donations and not advertisements. So extra useless threads are what clutters this forum and causes the donations to go higher. So either you are cool with that and can see our frustration and adapt and enjoy your stay here, OR you can get butt hurt, cry and whine, and we can make your life miserable here and send you to a extremely shitty forum like mazdas247.com. You choose your fate...

its a combination of the torque output of the motor, and the absence of a front motor mount. The engine sits on two different mounts on the drivers and passengers side. with the mount in the rear being a "roll stop". The first part everyone replaces is pretty much the rear motor mount. Its a common trait of this car for there to be a good amount of engine slop when slamming the gears.

Sounds like they put 87 octane in that bitch or a waste gate problem like I had one time. Easiest solution though, go test drive another one and see if it does the same thing lol. If it does, then it just needs RMM more than likely but that's shitty of mazda to produce cars that will knock like that from factory...

So after he stated that he pretty much slammed the car into 2nd gear and was beating on it, and after everyone said its the RMM because it has been documented over and over again, you come up with waste gate problems or 87 octane?!?!

Well why would I want to post another ANSWER about the RMM? I was giving my personal example when that happened to me, and it wasn't a RMM that fixed it. Sorry for not thoroughly having the time all day long to read every single msg on here.

I am stock with a 2011, no mods. You have to manage all that power and respect the drive train with your foot. I mash it only once I get going, say 30-100, I don't have to burn rubber and introduce wheel spin, torque steer every time I take off. I love the car's strength and how it pulls in third gear and at the higher speeds--and how it handles. That's where I surprise cars.....including a Corvette yesterday who gave me a brake test. He did not like me lingering 4 car lengths back and keeping up with him. I was so far behind him, it did not matter I just let off the gas. That is what is so great about this car and why I love it so much.

[Pintozoz]

wheel hop. How have you never felt this on your car?

[Pu Manchu]

@IWannaGoFast it's nothing to worry about, the turbo will eventually make room for itself in the firewall, and then you'll have more space for an even bigger turbo.

[Koke382]

[ThizSpeed3]

i herd the same thing when i drove the car the 1st time how it was supposed to be driven , never herd it again since than gramps

Don't give out this secret! Everyone will want the cool firewall mod now...

[embibb]

Thanks for sharing .. I remember the same experience when I test drove. Fortunately I had been browsing this forum for a few days and gained some insight to the RMM being weak... Buy the car and ENJOY This forum offers a concise and unbiased opinion of a really COOL CAR...

[fortressofcomfort]

Driver mod needed? I drive my car plenty hard enough and have no plans for an upgraded RMM. To each his own I guess. Still, anyone shifting that hard needs lots of practice. Also, I have never ever had an ounce of wheelhop in this car. I know what wheelhop is too; its what did in my last car's transmission :-(

[johnspeed3]

It's just the rear section of the motor hitting the firewall. Upgrade the stock Rear Motor Mount and it will be gone. These cars have alot of torque and the stock rear mount sucks.

People, please stop regurgitating what you read and spreading false information.

It is IMPOSSIBLE for the engine/turbo to hit the firewall with all three engine mounts intact.

Go jack up your car, get underneath, and remove your RMM completely. Rotate the engine fully forward and fully backward. Notice how nothing makes contact with the firewall?

The noise most people hear when they shift hard on the stock RMM is the metal portion of the RMM bottoming out on the subframe when the bushing allows excessive travel. If the RMM is removed, the transmission adapter bracket it attaches to will hit the steering rack LONG before the turbo or down pipe decides to share space with the firewall.

Do you dopes really think that Mazda would have designed the engine bay and mounts to ALLOW the engine to contact the firewall?

[beachshoer]

Yes.

In the end its the same thing.

Weak RMM is the cause. You even said it yourself. So who's the dope now?

Hypocritical motherfucker. And why the fuck are people still trying to answer this question? What a waste of space.

[6Y MAZDA]

Lol i think OP should go back to the dealership, tell them he dogged the shit out of the car when he test drove it, and he thinks he broke it. Come back and tell us what they say

Of course you can't move it with your hands you dumb cunt. Thats what 300 lb/ft of torque will do. Just because you can't recreate the problem with your pathetic excuse for muscles doesn't mean the fucking 3500lb car can't. And yes Mazda would sell a car like that. They used the exact same RMM on the speed 3 's that they use on the regular 3's.

What the fuck is wrong with you? Take the hate somewhere else faggot, my post wasn't directed at you. Go eat a dick.

I guess I'll have to make a video to show you mechanically challenged fucktards what I mean, since comprehension of written English is obviously not your strong point.

Then again, why should I bother explaining this all to someone who drives around with purple headlights...

Just because it wasn't directed at me doesn't mean I can't call you out on your dumb fucking post. "Disconnect the RMM and grab your engine and try to move it forward and backward" that doesn't prove anything except you can't generate 300 pounds of torque to make the engine move enough to hit shit you dumb cunt.
Actually it is my strong point which is why you are getting all butt hurt because I called you out. But go ahead and make your video so we can all see how cool you are! Who has purple headlights? If you are referring to my 10,000k 55w bulbs, you would know they are equivalent in color to a 35w 8,000k

By disconnecting the RMM and moving the engine forward and backward, you are simulating the application of high torque load. You can move it forward and backward by hand through a range that's quite a bit larger than any RMM would otherwise allow.

If you remove the RMM and rock the engine in the direction of torque load, the transmission adapter bracket will hit the steering rack and the turbo/downpipe assembly will still have several inches of clearance to the firewall. The TMM and PMM would not allow that extra movement to occur unless they're severely damaged, which is moot because the OP was test driving a brand new car.

I'll take my dumb cunt elsewhere; you can have your topical, constructive thread back now.

I would like to point out to the dumbass known as @outshined That the Ford Focus ST also has the exact same problem with it hitting the firewall that we do.
