Need help in calculating high speed run potential... - Page 3

Never once did I say that a stock crx would do 160mph.

826hp to go 170mph!!! HA HA HA!

I said mine will go 135mph.

You are the prick saying it takes 224 hp to go 130mph on a 2200lb car FUQTARD.

I am almost positive that the "CRX SI R" will go 160 and handle the speed people are making 700hp with a 1.6L engine on the import drag racing circuit.

Your statements were the most off the wall uneducated, ignorant and outragous thing I have ever heard dont try to take it back now cause you posted that dumb sh!t not me. So dont get mad when I call you out on it.

I could even make the "SHORT YELLOW BUS" you used to ride go 170mph with 826hp.

One thing people need to remember is that weight does not have that much to do with top speed, only how long it takes to get there.
As for being able to predict how fast a given car will go, it's just too complicated without knowing all the details of that particular cars setup - it really depends on the final drive ratio, the amount of change in gearing in shifting from one gear to the next at high speed (i.e. if you shift from 4-5 at redline in my stock geared '00GT it comes out of the powerband because 5th is so tall and you are screwed), and what the engine's powerband looks like. After all that then you figure in wind resistance and other friction factors.
I say run that turd and then let's hear about how fast it can go.
We can all agree that in general for a given aerodynamic configuration, the wind resistance increases as the square of the speed. Thus an approximation would tell you that is a stock CRX with 108hp can do 125mph according to the car mag, then to go 150mph you better be packing almost 50hp more than stock, which is no small feat for an engine that size. (150/125)^2 x 108hp = 155.5hp.
The trick here though is that the car needs to be able to make that horsepower at the exact rpm that it would be going that speed.
That is the main reason why people's cars won't go as fast as they think they will.

And that's all I have to say about that. ;-)

And please don't question my education.
