breaking 120?
 

well, in my car, it won't go past 120mph. i figure its being limited by the computer chip in the car. so in theory, if i get a new chip (any ideas?) i would be able to break that lovely 120 mark.

hmm did u try going that fast ? i know i put mine once over the 130mph mark but with triple digit speeds it's not too accurate

if you tryed, what does it do when you hit 120?

I have a 5th gen civic, And have also put mine over the 130 mark.

i have put mine over the 130mph hour mark as well...i'm amazed at how many cars can't do that...?

i got a 97 DX. and once i get 120 and step on it it won't go anymore. nor my MPH or either RPM gauges (thats right, i have 2 RPM'S =P ) will increase after a certain point.

your engine just cant push your car any faster, if you hit the limiter, you'd know it. it would bring you down to 110 or something

remember that gearing matters as well. You aren't driving a race car.

i know, but this is for later reference. like after an engine swap and a turbo. cause the need for speed's gonna be there, and i wanna use it =)

you need to be careful what kind of car your taking to 120+. just because you have the power dosnt mean you have the car. you need to upgrade brakes(you WILL have brake fade by 90mph coming back down and crash if need to stop from that) your suspension(if you get a gust of air under the car, your gone, and if you need to switch lanes, body roll will kill you.) and the tires/traction(lots can go wrong) i had a video of a car hitting 140 but not being able to handle it, the front lifted, and i think the guy died.

ok..what chriscantskate just said....freaked me outa bit

Its true though. Most stock cars aren't meant to top out at 130+ (aerodynamically), and its not worth trying :no:

i'd rather freak people out than reading about another death. ive seen too many "<username> passed away last night" threads then they are about how someone tried to either speed through interstate traffic and lost control, or couldnt hold high speeds in their cars.

i with chris cant skate. my friend has a video of an integra that was flying over a hill and got airborne and of course the driver lost control, not to mention he passed away
unexperience drivers trying to make cars do things they cant handle dont mix :no:

85mph is fast enough for me....:rambo:

LOL;)

woah.. this thread is kind of freaky.

but i agree about the mph... i got up to 120 in my civic and its freaky feeling like u dont have control of the car.. def not something ill be doing again in that car :no:

I've been up to 138 in my spec. Every little movement you make is amplified.

yeah.. i did 135 in the lude, it felt too safe though, so i quickly got back to 90mph. i just dont really trust a $25k car above 140mph for some reason.

my civic feels more stable at 120 then my fathers 94 911 convertable did.

136 in my civic, it wasn't bad at all, no shaking, pretty smooth ride, almost like I was floating

wanna race? :)

that floating feeling is not good, lack of downforce? If you hit a bump you really would have been floating.

anyway there is a rev limiter on purpose if u take ne stock car honda or acura over 120 your valves, valve springs can break at such speeds... such a beating on the motor.. the fastest ive got my civic as 120+ i got my 92 nissan stanza to like 130 somethin an it never ran right after that

No!
honda/acura NSX... 'nuff said. j/k... no one driving that posts here anyway...

just think about how fast you are going and dont be stupid..... the only reason i did the things to my car is so i can pass the cars on the road that i need to....

125 i hit on midnight freeway and then it felt like my car had never done it before, smooth, but you just know somthin not right. ive seen them videos of cars flipping over in high school 5 years ago. Integra, Is300, civic, nsx, all good then like nothing there flying like leaves.

i'd say a h22/b18c5/b18c1 can handle those extended periods of revs... remeber your tranny is taking the major abuse of spinning, not the motor. 6k rpms is 6k rpms on the motor at any speed

you really think so? i want to believe that... i feel like i shouldn't drive my b18c1 the way i do. i commute like a madman- 180 miles roundtrip everyday. my car is garaged right now, but when i was doing my commute with it, i was almost paranoid to drive that car fast for extended periods. because of the low gearing, driving 80 (no admission of guilt) put the motor above 4000 rpm, and 90(again, i'm not saying i ever do that) would be over 4500. i know this engine is designed to spin up to 8000+ rpm, but that extended period at such a high piston speed makes me worry. i posted a thread about that when i first got the car, but no one ever answered what a "safe" cruising speed is. do you know? the one thing i think makes the rsx reign supreme over the integra- the available six speed tranny... i love my 'teg, but i know that when it's supercharged(one of these days) i would like the car just that much more if i could tear through fifth and drop one more gear... and that's really only for peace of mind, because it makes me worry to turn 4k+ rpm for an hour and a half.

what's the worst that could happen? the crank seizes and the rods go out the oil pan. ;)

just to clear things up, the limiter will not reduce your speed. I hit my limiter a fair bit 132mph and it just wont let me go any faster. I have 1800rpm left and even goign down a hill i cant bring my speed past 132mph. Drive safe everyone, i wouldn't ever take a civic up that fast, though my car feels great at those speeds.

Cheers

I would hope that all of you that are going 103+ have the right kind of tires for that? Unless your tires are made for those speeds such as the Z type tires 180+ :bow: I would never go that fast. And that "smooth floating feeling" you are feeling is the tires expanding and contracting causing a ton of heat in which will make your tires explode:o So my suggestion would not go over 103 unless you have the car for it:no:

think most of us probably have at least v-rated tires, good for 149 mph... z rated is over that much, but they don't specify how much over. the tires are rated at those speeds for ten minute periods- meaning they'll last at least that long for the rated speed. i think part, if not all, of the floating feeling comes from all the air going under the car... making it "lighter". look at the speed ratings below...

N=87 MPH, 140km/h, Spare Tires
P=93 MPH, 150km/h
Q=99 MPH, 160km/h, Winter, LT Tires
R=106 MPH, 170km/h, LT Tires
S=112 MPH, 180km/h
T=118 MPH, 190km/h
U=124 MPH, 200km/h
H=130 MPH, 210km/h, Sport Sedans
V=149 MPH, 240km/h, Sports Cars
Z=149 MPH, 240km/h and over, Sports Cars
W=168 MPH, 270km/h, Exotic Sport Cars
Y=186 MPH, 300km/h, Exotic Sport Cars

Z is the highest rating included in the tire size, i.e.,
P225/50ZR15

W and Y are included in the service description, i.e.,
P225/50ZR15 91W

after i break 100 i get scared to death, you feel like every little bump

thats a scary story..... I once drove my car 140 + mph for 20 miles. It was pretty scary driving at that speed. Turning was alittle scary.... but yeah.... I guess like with anything else as long as you know what your doing and don't make any sudden movements you should be ok at any speed........... But i definitely recommend getting some suspension if you decide to go that fast. It is a must..........

what mods do you have to your civic to where it can go that fast

I just had turbo in my car and a very heavy foot.....

My car tops out at 120 too, it's a 92 civic Lx with mild modifications. I have yet to hit the nitrous at that speed. I have 225 tires and a good rear wing so I stick to the ground. My car is also lowered. It feels really safe but it's really loud due to the exaust. What do you all think would happen if I hit the switch?

might blow the engine cause of the RPMs but i dont have experience with Nitrous so i have no idea

my barely hits 120 it won't go over that ........

Re: breaking 120?
 

What mods do you have? I thought the USDM civics did not have a speed restriction on them. BTW, my mom's stock 2000 civic lx wont go past 100mph in 4th gear - but i have gotten my car up to 127.
