just surfing around they had anywhere between 46 and 52... not really sure why so i figured 52 was fully decked out.... but why wouldn't a GT500 be already decked out.
as far as the weight goes for every 100lbs you add you lose about 10hp.
the mustang is 698lbs over the vette so that means its down 70hp vs the vette.. so its 505 vs 470 head to head
um you do lose hp by adding weight, no you lose time. and it's .1 for every 100 pounds
at 44secs is that a push rod engine? that would be sooo fucking stupid.

you also don't buy a 45k 54k whatever to dump 22k into it. sure some prick with too much money might. But people don't say I want a mustang that will beat a z06 so lets go buy the top of the line and drop the diffrence into it. You go out and find the cheapest ass mustang cause you know its getting gutted. And if you had a choice between and f-car and mustang to use to try to match a z06 in terms of handling and straight line.......... well you know you'd pick and f-car

By .1 I would assume you would be speaking about 1/4 times. Well not every car has the same power curve TQ and HP, so you can't really make a statment like + or - 100lbs would result in a gain or loss of just .1 in a 1/4 mile.
But you can say + or - 100lbs would result in THAT car performing as if it had 10 less or more HP.
How much faster or slower the car gets from the adding or subtracting of weight is up to alot more factors then pulling a number out of the air. This isn't the school of bench racing.

stop talking out your ass. thats not how it works.

try explaining your thoughts in a sentence next time. works better then name calling.
it was early in the morning and I was running out the door that was the best thing you were getting at the time.
why don't you explain why you think you're right. cause by dealing with the weight of the car 100lbs is equal to .1 of a sec. and yes that equates to all cars and I'm not the only one that says this.

lets just say we are gaining 10HP from losing 100lbs
vs
gaining .1 by losing 100lbs
the reason I say you can't say a car would 100% gain .1 from 10hp is because it depends on the whole setup of the car
gears - power curve - torque - RPM range, all of that. depending on the setup of the car it might gain nothing from 10hp maybe it will take 30hp before it gained .1
but you can say the car will perform as if it has and added 10hp, if it goes faster or not is a fuction of everything as a whole.
As you know you can gain x.xx in the 1/4 mile just by doing gears or a stall converter.. you didn't raise the HP but you've made the car faster.
There is also sprung vs unsprung weight advantages but you get the picture.

yeah but we're not talking sprung and unsprung we're talking static weight. for our examples we will assume that nothing else on the car is changed but the static weight. with less weight to move, the car will get faster.
yeah so f=ma where f=force m=mass a=acceleration a=f/m so as m gets smaller a would get larger essentially making the the time to cover a given distance faster. now for 99% of the cases this holds true 100lbs = .1 sec is the average of time gained or lost for the weight. weight has no direct relation to hp by adding weight it will not effect hp and the other way around.
thats something a ricer would say. "I lost 3000lbs so I must have 50,000whp"

my point is you would be getting more for your money with the mustang than with the Z06

Yea there really is no point in saying "it's like gaining 10hp, it's like losing 10hp"...it's too erroneous. Horsepower isn't even a "thing". One can't measure horsepower, it's just a made-up term by making Torque a function of RPM. Power production has nothing to do with mass, and by saying a 2500 lb 300hp Civic would run the same time as a 2600 lb 310hp Civic is pointless.
As I was just discussing with RedWabbit....F = ma. a = F/m. The smaller m gets, the larger acceleration gets.
0.1s per 100 lb is a nice average that usually works. But trust me, to actually measure 1/4 mile performance using numbers, you need to take in several factors, and you need to thoroughly understand Vehicle Dynamics. It took me over 300 lines to write a program to accurately estimate 1/4 mile times that probably has a 5% error from the real world. It takes into account traction forces, drag forces, tire forces, weight distribution, gearing, final drive, the torque curve, sprung/unsprung weights, friction coefficients and more.
Edit: 10hp here or there doesn't have enough of an effect compared to only changing the mass. Traction forces, Drag forces, and gearing will always have a much larger effect than even adding 10% more power. Mass is the only thing that has a direct effect on the times no matter what. Also, it should be noted, that mass removed from the wrong place, can even make you slower (even if your traction capabilities haven't changed)....from the squat/dive characteristics of the suspension.

just that a 3000lbs car with 210hp will run like the EXACT same car that is
2900lbs and 200hp
ONLY on vehicles with very linear power curves.
Otherwise, all bets are off. If it's more of an exponentially shaped powerband, that 3000lb 210hp will beat the same style powerband 200hp car.
Or maybe the extra power lets that first car get into VTEC first, and it will still beat that lighter car.
So in the end, you CAN'T claim what you're claiming on a general basis. However you CAN generally claim that a reduction in mass can be equivalent to a drop in E/T.
