Going Hi-Tech To Catch Loud Cars

Two completely different topics. He was talking about a car alarm going off through the night. Not exhaust noise. And I've also never said there shouldn't be ANY laws. The dB level is just far far too low.

We have proven this in my area with independant testing at the hands of a LEO friend.

Read and comprehend fully before replying.

How so? If your going to call me out prove it? I'm not the one laughing at upping the idle to deal with solid motor mounts, which any idiot in the car scene would understand. Yet I'm the one with lacking knowledge? Call me out.

The fact that your solution to vibrations was to raise your idle to 1,500 RPM screams ignorance. If you paid someone to raise the idle that high they should be out of business.

I love your one liner repsones. You don't have a clue. School me. What would you do to smooth out the idle as a result of solid motor mounts?

I look forward to passing on your response to the rest of the auotmotive/racing industry to let them know they've been doing it wrong.

Your rebutle to, I'm not even sure what, is to reference this?

Loud cars suck. You can have power without obnoxiously loud exhaust systems. I also think fags (harley riders) should be taken to task for their obnoxious noises.

There's nothing inherently wrong with such a high idle. It feels much smoother in the car. Hell on my car if I'm idling around 750RPM it has a fair bit of vibration. But if I raise it to 1200-1500 and were blind and deaf I'd have no clue the car was running at the time.

This is the case in a number of cars. The reason the solid mounts when in my car in the first place is better response, and I was told that the increased vibration wasn't that bad by other owners. Unfortuantely It was a little worst than I had expected.

Hence the idle being increased enough to smooth it out. Any car guy understands this. I'm waiting for Blown 89 aka "Haven't a clue" to reply with some fuel consumption rubbish or something ridiculous.

Please do that because the racing community I'm part of realizes that raising your idle to 1,500 RPM is an idiotic thing to do.

Yet you still can't provide a reason or any facts or even an alternative. All you can provide is "You know nothing, that is wrong but I can't tell you why"
 
solid mounts in a car just limit the movement of the engine/transmission. allows for easier shifting at high rpms, and reduces Wheel hop ( fwd) gaining more traction. It also improvs the handling a small bit, as the engine isn't jumping around the the bar under hard cornering conditions.

street cars shouldn't really have solid mounts. There is a purpose they are not solid from the factory. One it fatigues the metal supporting the engine, two harsh vibrations but hey if your a chick you might like such things. I've seen and repaired many busted front ends due solid mounts, there is just no give so when it does give we are talking about ripping sheet metal. Semi solid mounts are the best for street cars.

As for car noise i already posted about that, simple fact other trucks. machines are easiliy over 80db. 100 DB is a much better limit to go by.

It really depends on the motor you're using.

If you have a typical small block v8 that idles around 300-500RPM, 1500 is nuts and completely unnecessary as the v8 layout has a well balanced firing order. An I4 with a 1-4-3-2 order is not well balanced. When stock at-running-temp idle is 800, 1,500 isn't too crazy. The cold idle on my car will touch 1700-1800RPM sometimes in the winter. That's the stock design. But there are unusual design parameters with mid engine that also deem a higher idle appropriate.

I agree 80db is a little low, but 100db is very high... About 4 times louder than 80db...

90db is about double as loud as 80db.


Somewhere between 80 and 90db seems to be the appropriate limit to me.

I was actually mistaken. It's been awhile since I even took my car out. I checked my map and I actually I idle at 1200rpm.

Agreed on all accounts. My car is a weekend warrior that sees track days, so the solid mounts do suit my needs. Daily driver? No way.

Increased carbon build up, driveline wear, unburnt fuel discharging, heat buildup, etc, etc. I don't care what car or what engine you have, no car on the street needs an idle that high.

I agree it's kind of a misapplication to put solid mounts on the street. Actually, a lot of times saying solid is a misnomer. Some people call solid (as in full, no holes or louvers cast, just a block) cast polyurethane with a fairly high durometer to be solid mounts, some people use delrin or make a solid metal bracket and bolt it down. (that's pretty hardcore solid).

You're best off allowing some flex in the mounts as to not destroy your frame/firewalls. If it can't bend the material, it'll just destroy it.

Again, I think it depends on the engine. A lot of the I6 engines barely feel a difference from solid motor mounts. I do agree that the potential is there for more problems but that could be said for a lot of things when you get into modding cars. Some guys want every ounce of performance they can get and really don't care about potential accelerated wear on other components.

I myself have cracked my exhaust a few times as I have no flex joints and solid mounts. I'm well aware of why it happens and it is my choice to run the car in that configuration so I just chalf it up as an operating cost.

It is MY CHOICE. Something I like having and everyone should have. Which is the purpose of this thread in the first place. Everyone has a choice, and you don't have to like theirs nor do they have to like yours.

Having a low idle can be hazardous to your rotating assembly. Your oil pump displaces very little fluid with the rotor turning so slowly. A couple bearing contacts because of low oil pressure/volume eats those things up.

Carbon buildup - uhh ok. Have you been watching gasoline commercials lately? That's really not much of a problem.

Unburnt fuel - Maybe. As your O2 sensor keeps reporting lean/rich conditions to maintain your idle as close to stoichiometric as possible, unburnt fuel shouldn't be much of an issue. It's still wasteful, just something the driver should decide for themselves and you should kindly butt yourself out of the decision making process.

Heat buildup - There's a cooling system with a thermostat and electic fans for a reason.

Yeah, I still get tickets for my 1950 Harley every so often. I beat them every time because it came from the factory with a straight exhaust. I love grandfather laws. Many bikes up until the 80's have straights, or just tip baffles that are not much better. I try to be reasonable though, as soon as I turn off of the primary road onto my side street, I cut the motor and coast into my driveway if it is late at night.

Not even going to mention how poorly shielded 50's magneto ignitions can really play havoc with modern electronics. Thump, thump, thump.

Agreed. I hate it when I'm sleeping and at four in the morning I hear some damn Harley drive by. I live in a neighborhood, but you can hear the damn thing through the whole block.
 
you are putting your own interests above everyone elses. Its not bothering me, its bothering everyone (except you apparently)
Click to expand...

What right do you have to speak for 'everyone'?
You don’t speak for me at all.

Yet I suppose SKiTLz has proven his point in this thread to me. The citizens of this country are paying out the ass for tons of wasteful government spending. Somehow the idea of making people pay money for an incident in which no one is harmed and burdening the population more sounds like a good idea.
Before I move on, if your argument is that most of the population wouldn’t miss it. Well I thought I lived in America and I didn’t know I had to decide my interests, loves, and hobbies based on the decision of the majority. I swore this country was constructed with freedom in mind. Does loud music bother you? Loud noises in general bother you? Those things upset you? So fining or banning is the answer!

Right?

Wrong.

Almost daily I see or hear things that upset or annoy me. Want to know how I deal with it? I keep moving, end of story. Would I be sad if shitty music just suddenly stopped being played loudly in America? Yeah I would but I would never suggest some sort of legal measure by which we could extinguish it ourselves. I don’t take joy in holding other people down because they happen to enjoy activities I do not. It’s just sound and nothing more...From low hanging pants, to rap music, to loud cars, to marijuana, to what else?
I get sick in my stomach when I find myself asking this question in anger but I have to ask it.

In what way would you prefer I live my life so as to not disturb you?

We should put noise restrictions inside neighborhoods because god damn those super bowl games and Fourth of July parties are nonsense I might not agree with. While those loud jerks partying and enjoying life harmlessly next door should cut it out cause I need to sleep.

Ill end my dysfunctional rant with this.
In life you are going to deal with being woken up when you are sleeping. You are going to deal with music you don’t like. You are going to see cars that upset you. You are going to have to learn how to tune it out and stay calm because it isn’t anywhere near as big of a deal as you
 
Its really funny. Hey I heard they are going to outlaw murder to
so pretty soon there wont be anymore yay... O wait they already
did that hmmm

Well that makes sense! Since you know, Murder actually harms another individual!
If we were to limit what we outlawed to things that are scientifically proven to harm another individual then we can get things done!

On another note, I don't mind cars that have exhaust systems, but I have a screw loose when it comes to loud bikes. The sweet purr of a Quadroporte, or the rumbling of a 'Stang, or any other muscle car...that is music to my ears. Loud fucking bikes on the other hand just grate on my nerves. I become a homicidal maniac when one of those drives by. No, I am talking about a Hog that's just driving by, I hate non-stock or overly annoying choppers that drive by every now and then.

I believe that we both are agreeing on the same subject...

Making something that is harmless illegal will only cause more problems.

I do listen to my music loud when Im driving but If Im at a light I always turn it down (almost always
unless someone issues a challange (turns there music up)) And also dont play it loud near homes(most my driving isnt near any anyways) 5 min before I get home I have to turn it down to let the system charge back up(hits way to hard 120amp alt and yellow top bats isnt enough) :(
 
Ya also put a total of 2k miles a year on my car so I dont think Im bothering to many people.

3000RPM? OHH NO.

My car idles at 1500RPM cause of solid motor mounts. 3000RPM is nothing. The 21st century is soft. Citizens these days are just complete whiners.

Cars are a hobby/interest of many. It's unfortuante there are some asshats, but guess what if it isn't a loud exhaust it'll be something else to wake you up. This mentality of "I don't like it, ban it" is a joke. You don't like something? Too bad. Everyone has dislikes. We deal with it. Banning everything and creating laws to baby sit everything we do is not the answer.

great post!
 
I will say this much.

I think noise is fine assuming its within a certain dB range. There is a point where its hurts the ears of pedestrians and is just plain obnoxious in residential areas. Most cars dont bother me, its really the E-Peen motorcycles and Jake Brakes. Honestly, I am not trying to prevent people from enjoying their hobbies but there is a certain point where its just too much.
 
Good loud cars are annoying as fuck.

They are like loud PC's before the whole quiet PC movement. No longer cool and a relic that should have been killed off in the 1950's or 70's or when ever the hell people thought putting crap on your car to make it louder was cool.

bust them and turn the cars to scrap metal I am sick of hearing the things on the road or drive by my house.

I want a fucking tesla roadster that makes 0 noise it is just a sweet ass cool Future like hum that sound like the fucking Knight rider cars.

unless you are this dumb ass who ruins it by adding Big ass speakers and fucking loud car sound effect to it.

I bet i can hit 130dB on that. My car is super loud when i floor it. There is only 12 inches between the exhaust valve and the exhaust tip. Open downpipe baby.

I just put down a reservation payment for a 2012 Tesla Model S.
  • slightly larger than a 5 series
  • can seat 7 (with two kids in the optional rear mounted folding seats
  • No engine up front means two trunks (and they're big!)
  • Largest battery has a range of 300 miles
  • Instant 0-rpm torque, 0-60 i 5.6s
  • top speed 125mph
  • sick 17" touch screen in dash
  • only slight electric whine
  • Ought to have best in class handling (due to torsional rigidity of battery)

And it looks amazing :)
