bgoetz alright thx i just wanted to be sure i got exactly what he meant.
and as for the whole thing of a saturn going 200mph... do you think that was with a stock tranny and that they didnt modify any other parts or replace any other parts... if your talking about salt flat speed records or something like i think you are. those cars are like funny cars when you break it down to stock parts theres barely any left.
bottom line is there is no way our car could handle those speeds, unless you modified it to do those speeds in which case this topic is friggin ridiculously unnescessary because i would hope everyobody knows that anycar in the world can go 200 mph if you " modify " it to get there.

hey on a side note i used this calculator to figure out my approximate top speed since my speedometer only goes to 120 (i guess i only have 120 hp accourding to the one guys dumbass buddies) anyway using the calculations on the chart i have hit 140 mph in my pickup truck lol and it was really stable

and if you want a few parts ... well chances are youd need a buttload of hp and tourque to get our cars to 170 so unless you baby it youd be smart to replace axles because they could snap, also the body would twist in ways a rubber band cant even twist if you got that fast (please dont take my exaggeration serious cus i know someone will), also theres plenty of bearings which i dont think are designed to be put to that stress inside the tranny and other places, and im not saying honda doesnt make good parts i love honda its that they dont make a part stronger than it has to be because that would cost them more money and car companys are all about making money. if you really want me to ill talk to a guy that has been completely dismantling and repairing and rebuilding auto trannies and manual trannies for like 35 yrs. (thats all he does everyday) ill ask him if a honda civics 5 spd could withstand 180 mph or so or if it could handle the hp it would need

this thread has turned into a rediculous aguement.

this is retarded there is no way in hell a fking ex or any civic will reach 170mph.
but im not an idiot this is relative to moddification of course.

the original thread was about a stock civic. :GAY: (oh there is no icon for that well you get the idea)

this the **** that domestic and higher end car owners laugh at import owners about

i agree people are missing the point of s2000. He's sayin the tranmission is designed to go up to 180mph based on the gearing. The gearing is probably less aggressive to save on gas. In real terms, i think a stock civic tops out at about 120-130mph. I've hit 120mph on my ex auto civic at 6k rpm with aem sri. When i was alone on the 5 driving from north cal to so cal late at nite. It makess more sense that our cars are rpm governed rather speed governed considering a rpm governator would protect the engine from damage when you over rev.

thiscrackerntam

maybe not with you its not a debate, but it is with these other boneheads that wanna refuse to believe that atleast some of the EX's are not speed governed.

True that. Mine isn't

here's the calculations you wanted

S2000man01

iTrader: (1)

you are over-emphasizing the amount of mods it would take to get a civic to the top speed it's transmission would allow.

to get there, you'd need some more hp (ala turbo), remove the governor, better tires, and that's pretty much it. you might wanna do some suspension tuning to help you drive the car at the higher speed.

you dont need to make a civic a funny car to get it up to that speed.

S2000man01

iTrader: (1)

you underestimate the honda. do you realize, for example, the stock honda crankshaft can withstand 600+ hp? trust me, if you slap on a turbo and remove the governor, the car isn't gonna "fall apart" or suffer any damage from going to 170mph.

next time how about you read and discuss the topic rather than flame like an ***.

Why can't someone put an EX 5-speed on the dyno and run it to redline in 5th gear and i guarantee you it will get to around 150 or whatever that calculated number is on the speedo. Air resistance wont' be a factor and you can see what the top speed would be with no resisting forces besides the friction on the dyno. Someone try that if theres a dyno that will handle speeds that fast.

S2000man01

iTrader: (1)

you'd have to remove the governor first. also, i dont think most dynos will let you run a car to 170mph on their dyno.

i used that calculator for my friends celi gts its says he can go 183 mph..

scansel912

iTrader: (4)

I don't think EX's are speed governed because alot of people say they have gotten them up to 130 or higher. I think the only governor is RPM fuel cut off which would act as a governor in EX's in 5th gear.

bgoetz

iTrader: (1)

and as far as even needing a ton more hp or axel shattering torque you don't really need that to get to 170. I say about a 5 mile straight at closer to 180whp with no governor would get a civic up to 170. You have to think a civic is not that aerodynamically inefficient were you would need that much hp. I think that is his miss understanding

heres a question. if our cars were gear differently, lets say to max out at 130 or 140, if u use the same calculations, wouldnt they actually run the quarter faster? and just in general be quicker in auto-x and stuff like that?

bgoetz

iTrader: (1)

no gearing for top speed and gearing for speed are two different types of gearing it all has to do with the final gear, of which you will never use in the 1/4 or auto X

ricergribbs

iTrader: (3)

right, but if we were to shorten each gear wouldnt that make a difference?

bgoetz

iTrader: (1)

to a point it would make it quicker, but then your final gear would be shorter and top speed less. And that is why there are 6 speeds for shorter gearing and a good overall high end

ricergribbs

iTrader: (3)

right so thats what im asking. wtf is the point of gearing civics that high? change the gearing a bit and bam! our cars are quicker lol.

bgoetz

iTrader: (1)

for efficiency you don't want a fuel efficient car running at 5K in 5th when you are cruising on the highway at 80

Zzyzx

actually a 6 speed is used to shorten the gears for quicker acceleration (by keeping the engine in its powerband) the 6th gear is typically simmalar to a 5th gear on on 5 speed transmissions.

Example
RSX-S 6 speed gear ratios.
1st = 3.267
2nd = 2.130
3rd = 1.517
4th = 1.147
5th = 0.921
6th = 0.738

RSX Base 5 speed
1st = 3.267
2nd = 1.880
3rd = 1.212
4th = 0.921
5th = 0.738

notice that the RSX-S's 5th and 6th gears are the same as the 5 speeds 4th and 5th...

so ricergribbs is right, Shortining the gearing would improve acceleration, at the cost of top speed. which is why I run "Short" tires to alter the final drive ratio of my car, effectivly shortining the gear ratios = better acceleration

another example... The Lotus Elise has an official top speed of only 135 MPH.... But it gets there real fast.

ricergribbs

iTrader: (3)

ah yes, didnt even think of that lol. still... bastards @ honda screwing us over...

bgoetz

iTrader: (1)

Sorry if I was not clear, but I meant the same thing that you just said

S2000man01

iTrader: (1)

yes if you geared the car to top out at 130 to 140 (assuming you change the FD), the car would fly through the 1/4 mile faster.

edit: i see this has been answered

ricergribbs

iTrader: (3)

so... how much would a new transmission cost? LoL

ncirom2003

iTrader: (7)

s2000 ill agree to disagree since you disagree on agreeing with me ... agreed?
and dynos are normally testing a car in third gear i think

Calculate the theoretical top speed of your car neglecting rolling resistance, wind drag, and other variables in real world physics.


this is the first sentence on that page.... those last three words are enough for me

S2000man01

iTrader: (1)

right... in other words, calculate your top speed based on gearing, wheel circumference, and redline. they put in the part about drag, resistance, etc, because you'd need enough hp to get to the top speed in the first place.
