The dampener isn't hitting the hood, or at least it shouldn't be. But i have so many rattles i can't distinguish anymore... haha

Might be your cat's exhaust sheild.. mine rattles on startup since its cracked but when it warms up the metal expands enough that it doesn't...?

 

Confirmed, there is a rattle because it absorbs the vibration. It can't exactly absorb all the vibration and therefore it will rattle a bit. The engine does need to rock a bit, back and forth.

 

^ i got scared the first time i started my car with the hood open, it looked like the engine was haveing a fit

 

1mph means nothing in the 1/4. You can win by seconds and still be slower than the loser. Net time matters, and the science there doesn't back you up. "change in distance"=1/2at^2 where a=acceleration (assumed constant) and t=time in seconds. you can be going 100mph and still lose to someone going 90mph in the 1/4 depending on their acceleration. In any case, top speed means absolutely ZERO in the 1/4.

I'm not sure what science you are using to back this post up, but it's new to me. Kinetic energy is mathematically defined as 1/2mv^2 where m=mass and v=velocity so where is it that the removal or addition of mass is not going to effect the energy of the system? Please don't mislead people here.

Look at it this way:

If subtracting 25 pounds in the quarter mile doesn't net you 1mph faster, do you think ADDING 25 pounds to the cars weight will add more or less than 1mph to your final time? I am willing to bet, especially for our car which is very limited in overall weight capacity due to the small engine, it will be more than 1mph.

I could do the math, but only with a constant acceleration, and it wouldn't prove anything due to that fact. Our acceleration is not constant, but doing the math with constant acceleration the lighter car always wins.

Anyone else want to venture a guess or actually have ET's to back this up?

 

OWNED

 

not ment as a negative post, but it's good to see someone agrees with me.

EGK-69:

This is for information purposes, as all my posts are supposed to be (unless otherwise noted ) so don't take offense because I said you were wrong.

Thanks,

i seriously hope you don't truly believe that.

take a box, push it across the table, effortless. put a 25pound weight in the box, and push it again. yeah, more resistance.

 

^ I really don't know about that example. I see your point though.

 

alright, not the greatest example, but yeah, my point is weight makes a difference. yeah, the 3pounds in this case is moot, but the heavier the load, the more strain on the engine. it's just not so pronounced on our cars because of the torque it has. i used to drive a 96 corolla, 90hp, decent for daily driving, but add so much as a big load of groceries, it could barely make it up a hill.

 

A classic example of weight making a difference is Arithmetic's video on Youtube. Do a search for "Mirror Battle - Ralliart vs Ralliart"

 

damn, you wont get any fastar, by anyway (mph or time) with 3pound less, simply you wont, i even doubt you see a difference by adding 25 pound, so what difference could be to have both things on the CAR!!!!!!!!!!

NO DIFFERENCE at AAAAALLLLLLLLLLLLL,

I dont care what you think, if you think you will be slower because you have (the TQ damper + the solid mounts) you are completly wrong, go and see it for your self.

It wont be slower not even by.001 on the track, I can maybe be faster, because of a more solid engine, less wheel hoop, better 60ft times, better 1/4 times

So whos wrong!???


Thank you Very much, thats all for today, do the homework and then come back to me.

 

You both have points there.

Given the mathematics by Dan, thats true to an extent however, with other examples 3 pounds won't make a huge difference in a 1/4 mile - If not any.

There is too many other variables to consider.

 

lol, a lil OT, but yesterday we squeezed(sp?) into a toyota yaris(lil 1.5litre) and omg it would barely move...
so yeah 6x~95kg = noticeable difference

 

Well as a Japanese car in Australia, every ounce doesn't count because of the metric system!

But theoretically yes its more weight; thus more power required to pull the car along, but at one item at that weight it is fairly negligible - unless you are at the point where you are throwing out all nonessential items, backseat, spare tyre, not driving on a full tank etc. 3 lbs is nada.

If it were I would remember not to go to the Sizzler if I was going to be racing after. That could be a Jenny Craig incentive for men though! Lose weight and your car will be faster!

I do notice the difference when I am alone in the car and my wifes work stuff is out of the boot (trunk) the car is a lot more responsive and fun.

 

im hearing noise like a can hitting metal, not sure if its the damper but t i never heard it before.
