Miata Vs C5

Actually power to weight is far from everything. It is important and nobody said it wasn't. Clearly, lightening the load will increase a cars potential for speed.

I've beaten C5s in my cars although my cars certainly heavier. Of course the driver is the single biggest factor, but there is more to it then any one issue like power to weight. From a standstill - you have traction. Higher speeds - you have drag. The power band and a dozen other things also make a difference.

btw - Good kill.

THANK YOU, I was beginning to feel all alone

Never said it wasn't important, just said it wasn't everything, read my post again. Are you telling me your miata is capable of over 170 mph? C'mon use your brain and think about this one. My old dirtbike couldn't reach a higher top speed because it lacked the nescessary power to compensate for the wind resistance and such. (it was not gear limited, believe me) So while your miata may be extremely quick, it is still not capable of the speeds of a C5. (so I believe your story actually, I'm just trying to clear up this whole power to weight theory) and your damn straight I'm comparing a dirtbike to a "turbo miata" and C5, because if "power to weight is everything" then it shouldn't matter what the vehicle is right? So it shouldn't matter if the vehicle is a miata or a C5 right? Your totally contradicting yourself... lol
So to sum it all up, with YOUR theory on "power to weight" (even with the proper gearing), my dirtbike should have been able to reach 170+mph.....ummm no. I picked an example like my dirtbike as an extreme example, because if I used something else, yall definately wouldn't understand.

I know my car is not capable of 170mph, becuase of gearing and the CD. I know I could go faster with a taller 5th or rear end. If your dirtbike was geared for higher speeds (and its most definatly not) it could get there, buts its a dirt bike..... look at a Hayabusa, tell me that power to weight AND gearing has nothing to do with it, it could be geared different and have a top end of 100....

Yea, but if it was geared for like 100mph, then the front wheel wouldn't have any use, might as well make it a uni-cycle then lol.

Yes, if my dirtbike were geared a little bit higher it would have been a little bit faster, but not 170 mph fast. you could get taller gears and shit for the miata but once you hit a 150 mph wind, your gonna need more than taller gears. The Hayabusa along with all other high performance motorcycles are are only like 2 feet wide and extremely aerodynamic. Your car is like a brick compared to those things. And if you want to talk about power to weight with those, let me tell you, their ratios far exceed yours beyond comparison anyways. (I'm sure R-1 rider can vouch for that) In other words, they are just scary fast, with around 140 hp and weighing around 500 lbs. that comes to about 3.5:1. Now, maybe if your car could lose about a thousand lbs or so and was extremely aerodynamic it could reach those speeds. But I still highly doubt it.

You would also get to that top speed of 100 mph in about 3 seconds

yeah, once you get up to 150mph, the air is gonna be the problem. the c5 corvette has a Cd of .29, in 97, when the car was new, that was the lowest drag of any production car. Im not sure if there is one better now, but that vette is still mad slippery.

power 2 weight only matters off the line

(remember physics - an object in motion at rests tends to stay at rest?)

well the more weight you have the more its going to resist acceleration

but at about 70 or so mph
wind resistance is a much much bigger factor than the weight of the car

the miata would probably have him on the 60 mph race - but more than likely doesnt have a chance to 120

aerodynamics is a huge thing at high speeds
the redesign on the 02 nsx dropped its cd 1 point
and raised its top speed like from 169 - 177 or something like that
quite a nice jump i would say

[TatII]

hmmmm the infiniti G35 has a CD of .26 soooo i guess the C5 is no longer the most aerodynamic car in production now.

i belive its called inertia:hehehe: :hehe: :hehehe: :hehe:

The murcielago has a negative coefficient of lift - meaning that the FASTER you go in that car, the MORE grip-creating downforce you get. I dont know of any other cars that can do this.

[|Banchi1O5|]

all cars with spoilers or other stability features do this

[Cbass]

The Ferrari 360 Modena has no wings and it does this... The Saleen S7 is a mad downforce machine. The editor from Road and Track says,

"As speed climbs and it's aerodynamic forces come into play, the S7 requires a deliberate mindset shift to accept that the faster you go, the more grip you have."

[|Banchi1O5|]

anything with a wedge shape (not isoceles but angled in a forward manner) is going to create downforce
and the faster air is moving around it the more df it creates
its creating it in terms of percentage

but considering things
like the self adjusting wing on the back of a 99 vr4
this actually changes its oriantation the faster it moves
therefore the percentage of downforce relative to the speed of the vehicle also increases
