How fast?

Took my car on the toll road last night. Got her up to 250 klicks on the guage before I backed down. I was running out of road. I know that you can't tell true speed from the guage but that is where the needle was at.
So what is your top speed?

Be safe.

So what is your top speed?
Be safe.

I find that funny:D

146mph coming down a slight hill. Car handled it very well, it was just planted. I don't think I would have tried in the Stang.

I find that funny

It's called calculated risk. Think about before you do it. Some people don't.

1 mph = 1.6
1 kph = .6

146mph = 233kph

nice

Quick question, how did the car feel at that sort of speed? or where you to busy hanging on to take much notice?
The Skyline is a nice heavy car, so should sit well on the road, but thier not the most areodynamic bricks ever built, I should imagine it would want to move around a bit.

that's insane!!! did you wear a helmet?

The R32s are not as bad as the R33s or R34s, at 146 it was very stable. I was actually suprised at how well it felt. Seemed to be at home, if you know what I mean.

I only tried it once, getting a ticket at that speed. Well, I think I would need to invest in some running shoes:)

Damn guys aren't you worried about the cops and safety of others? High speed though.

cops are not much of a problem where I am at. The road I take is a mostly quite straight way so I can always see others up ahead. But it is a relatively short lengthof road.

Well, I think I would need to invest in some running shoes:) haha by the time a cop would take off after clockin you , man youd be gone with the wind, all the cop would hear is the ambient sound of a whoosh as u pass him by ;) , hick cop would be like "um i just clocked a car going 150, dont know what it was , it was too fast, must have been one of them new toyotas"

Trust me Razor, I am never going to do that again. Highest speed I go to know is 85mph, thats it.

tony , no 70 mph !!

Yes, the Queens Motorways only 70.

I ment 85km/h, ya thats it...85km/h

One of the Australian mags had a high speed comparison on a airport runway.
An R34 (clutch, exhaust, boost) which did 4.5secs to 100km/h (timed) did a top speed of 256km/h within the space. Dodge viper got 280 something and the porsche GT2 got 302km/h.

Had my old 25t up to 257km/h once....... at least that's what the 300km/h speedo said, it may have been lying to me.

Does the GTR use a VSS (vechile speed sensor) or a cable driven speedo?

Im guessing that for the ATESSA and HIACS to work the ECU would need an acurate measure of the cars speed, which would require a VSS.
And its a bit silly to install a VSS and then have a seperate cable driven speedo, its actualy easier to drive the speed from the ECU. (same as all Honda's from about 1990 on, and infact most Japanese cars from about 90 on)

If they are fitted with a VSS then chances are that even at 250+kmh the speed will still be acurate, probably to within only a few kmh. :)

R32s use a cable, and I think the R34s do as well, but I am not 100% positive about the R34.

Here is a pic of the R32 with the MPH gear installed.:)

It actually uses something simular and both. The speedo is as shown is cable driven/operated, but also if you trace that cable up it joins at a little box. The ecu in turns picks up a signal from that to process that information for the ATTESSA.

God damn :huh: that, ummm somewhat primitive.
It clearly works, but well ask anyone with a rally car where the Halda is driven off a cable and they will tell you how inaccurate it is.

And wouldnt that mean that the cars fitted with a MPH converter are getting a signal being sent to the ECU that would be slower than the car is really going? Not something I would consider to be very good for the speed sensitive 4WS?

Ok, I've got to ask cause these speeds seem rather low.

When you guys hit them how much did the car have left in it? I'm asking because my cousin's 91 Protege GT has broken 140MPH completely stock. Actually it is in worse condition than stock, but with only a 1/4 tank and no back seats so it's down to just a bit over 2000lbs.

As has been mentioned speedos aren't that reliable but it reads to just past 140MPH and it was totally buried.

Had more juice to go but I had to slow down for the upcoming corners. Plus my heart rate was up there. Like I said before it was a short straight way. I am looking for a device with a true speed sensor though. I spotted somthing in a magazine with a lighter plug in that fits in the dash but I forgot what the name was. Like SkylineUSA stated before the car was hugging the ground very well with little or no shaking. In one word "Dreamy".

Just because a Speedo says your going over a 140MPH, does not mean you are, trust me. I have seen them off over 20mph at higher speeds, not say that speedo was off, but they are not that accurate.

In one of the high speed shootouts I read last year, one cars speedo said its was doing 203, when actually it was doing 178. And this was a very high dollar car.

Also, at high speed like that aerodymanics plays a major roll in speed as well. A few months ago here in the UK, they had a R33 go over 200+, with a radar gun, that was amazing.

To claim that 250kmh is "slow" implies either your driving some VERY exotic mechinery, or your just ever so slightly mad.

Its faster than most ppl will ever go in thier life, and altough with in reach of most modern cars requires such a long straight piece of road that most would never get the chance.

My dead Civic for example was in theory capable of reaching 240kmh before red lining in 5th. Iv never got above 180 in it becasue the speed cut stopped me, and because the car was never designed to be driven at that speed and started to become aerodynamicly unstable on our uneven roads. However I do know someone who has done it with a European car which never had the speed cut, he claims the car actualy settled down at 240kph, but he did the run on a German autobahn, where the road is long straigh and very smooth.
So although the car could get up there (ands it was a faster car than the average) it took a while to get there, and wasnt really happy to be there.
Its really any great acievement.



Iv hit about 240kph in a car designed to go that fast, and when you get there in the same time it takes most cars to make it to 100 and are able to do it on a county road with out realising untill you stop and think hey im pulling 5,000rpm in 5th, you know that your in a truely fast car.
I should imagine the GTR is a similar experiance.



On the note of accurate speed sensors, Cars fitted with a VSS will be very accurate, since its a purly digital process, there is no room for error from things like flex in the cable, or inacuracy in the speed mechanism.
But they are also very simple, and Im sure you could either build your own with a few simple parts from an electronics store and a circut diagram, or even adapt one designed for use on bikes.
The hardest part would be mounting a sensor somewhere where it will not get knocked or moved which will affect its accuracy. On a drive shaft would be the best option.

But I wonder if you could prehaps also tap into the ABS sensors signal and use that?

Well, as far as I can tell there were only 1200 or so imported to canada, but it's still a FWD Non-turbo protege. As for the slightly mad part I get that a lot, although the driver is a little more off, he's the one who jumps out of moving cars for happy meals.

True, but the car pulls surprisingly well in 5th gear and was very stable. I'm in no way implying it's anything compared to a skyline which is what prompted the question in the first place because it seems that a skyline should be so much faster.

This is what I was getting at :) I know that the skyline would reach 240 way before the protege but I expected that it would be able to keep going a lot farther. But then, I don't know what the gear ratios are like so it was kinda dumb to assume anything:bloated:

Personally I had clocked 245kph on the front straight at Sepang F1 track...the front straight is 0.9 km long.
I am not very much a speedster on the road unless an exotic car is constantly kissing my ass! Never went more than 220kph on the road.
But that crazy Nagata San (he who drove 200mph in a tunnel) had clocked 302kph in my car at 3 am in Singapore with the tacho at almost 8000rpm. The car has another 500rpm to go...so dunno the max speed it cud go....

Now thats impressive!
I think theres an almost exponetial relationship between a cars top speed and the amount of hp required.
Anything above 250 is impressive, 300 is crazy! :D

I remember racing a mates MK1 MR2 in my little kit car. He had a huge power advantage, I had a weight advantage. From 0-100kph we were equal (I had wheel spin issues all the way :D ) but at 100kph it was like my car hit a brick wall as the aerodynamics came into the equation.
For a car to get above about 250kph then it needs to either have a LOT of power, or be every aerodynamic, or both.


But then I find anything above about 160kph feels pretty much the same, and like all driving in a straight line is rather boring.

:) 145 mph (245 kph) in my dads mondeo !!!!!!

Ok, So my Skyline is in pieces right now and this thread sucks, because honestly, I haven't had a chance to find out what the little bastard will do and I'm getting kinda jealous.
Anywayz, I'm pretty sure that when its done it'll play at speeds close to or above the Supra I'm driving now. I've run the Supra up to 180 mph on the speedo and I'm farely confident that it is pretty accurate. The Stock Supra has a speed limiter set by the computer at 160 and they work show 160 on the speedometer. I'm also confident that the Skyline speedo is accurate to some degree, at least at around 80 mph because I've run past those nifty little "Your Speed" signs at 80 to see how accurate they were and they were always within one or two mph. So, what I'm saying is, when the car in done, well see. I'll get to do some testing at a track near here and I'm hoping it out performs the Supra.

Before I had my car chipped the lil darling's limmiter would come on around 180~190kph unfortunately the dial was way past the 180 mark all the way pegged out. I really hated the feel of the limiter kicking in. Always sucks to know you can go lots faster.

Now I'm wondering how fast I was going. The speedo said 165mph but I know it was at least somewhat off. I wonder how much though...

145mph in a mondeo, a few of these cars I didnt think those speeds were possible. Anywhooo, who cares about topspeed, it only matters how fast it takes u to get to the speed.
Top speed will have a lot to do with gearing. U can gear ur car to get to 200kph in 3 seconds but it wont go much faster than that, alternatively u could take 40secs to get to 200 and be able to make it to 300.
So top speed is gay.

So, what about some GTR's in japan thjat can get from 0 - 300km/h in a little over 12-13 seconds? Does that make sTop speed gay then?

You could also do tons of things to modify horsepower but not alot of people view hp as gay. True it does matter how fast you get there. I would not have been able to make that speed in such a short distance without a good car. Now I just wish I could get on a good track. Getting as much power and speed out of the car is part of the fun of owning it. Unless you want to go out and buy a pinto.

So top speed is gay.

considering that most competitions don't just measure the speed, but how long it takes to get there...

and most top speed runs have to be done in a certain distance...

also... gearing is one part, but if you don't have the power and aero to push past the limits and keep the car accelerating up to the top speed, you're not going to do it.

there's alot to it, and something i fully respect people for.

you can go really fast, but are you stable? how fast can you get to that terminal velocity?

is your car built well enough to get there and back unbroken?

there's so much to it...

I'm sure there are very many professional drivers out there who wish they could increase their topspeed on a constant basis. Of course they have engineers and mechs at their disposal. Along with financial backing. Thats besides the point.

I meant more with street cars, like the guy that did 145mph in his mondeo, sure, he may have done that, but he didnt mention that it prob took him a minute to accelerate to there.
Basiacally just saying I dont listen to, "ooohhh my car can do 180mph etc etc, know what I mean?
Much rather hear that, "My car does 0-100kmh in 2 seconds flat."

i've had my r-32 gts up to the red line in 5th, think that about 230 - 235km/h. the speedo was back round to zero. was real stable too.

Stock speedo? Limmeter in or out?

Limiter would have to be out if he got it to redline in fifth.

YEP, NO LIMITER, SPEED OR REV'S, CUT THE SPEED WIRE LONG AGO. I BACKED OF AT 7500RPM. I'LD KILL MYSELF IF I BLEW HER UP AT THAT SPEED. IT'S THE STOCK 180KM/H SPEEDO.

ALL DONE UNDER CONTROLED SERCOMSTANCES OF COURSE.;)

What ECU you running???

I'm not sure if I'm right on this one but isn't safety around 8500rpm?

This is GTS-T not GTR.

:( :o yeah definately took a while but we got there in the end!!!!!

AAHHHH! Still not bad for a GT ST. I'm curious how well tuned the RB25's can get. Most of the information I have seen are on the 26's.

185mph in my R34 GTR with three of my friends with me. That was my speedo reading so I reckon my true speed was approx. 170mph. The car was still pulling strong but had to slow down as we were approaching a bend.

185mph, wow.

:cool: for me it would have to be overall power then you can say your car accelerates like sh=t and have a good top speed as well but 185mph? thats just awesome:) :)

Remember guys, that 185mph was my speedo reading.
Also that was the first & only time I have been up to that speed. Everything was passing so fast! When I was back down to the speed limit(70mph), it felt sooo slow!

dont it just , and 185 , is jail time :( just a thought

for me it would have to be overall power then you can say your car accelerates like sh=t and have a good top speed as well but 185mph?

if your car has the power to get there, it won't be getting there slowly...

keep in mind that top end acceleration is more impressive, b/c you've got to work against the aero effect as well as the weight of the car..

so if you can go that fast, your gearing and power must be pretty good...

you can make anything go that fast with gearing, but it's way more impressive to do it with power...

like the gt-r here has done

STANDARD ECU, AND NO TURBO EITHER, JUST EXHAUST, EXTRACTORS, HOME MADE CAI, AND TICKLED TIMING. GOT A RAM EFFECT IN THE AIR BOX, THAT HELPS A LOT AT SPEED.

How did you remove your rev limiter???

don't no. ididn't want to,

Gearing is the main thing tho. If I have a GTR with a stock box and 1000hp (just say it could be done) Vs a stock GTR they both would have the same topspeed as they would both redline in 5th (or 6th in R34) and be going the same speed. Just the 1000hp car would be there alot quicker.
So I'm not saying that timing ur car getting to 200mph is gay, I am saying that saying "my car went 150mph" is gay, coz with gearing and a 20mile stretch of road, something not that good could do that speed. Know what I mean??

I am going to Germany in two weeks, I'll be taking the GTSt. I'll post what I get on the Autobon(sp). And hey, its legal:)

:p :p :p nice one keep skyline usa

:huh:

what did you say? /\ ???

it's interesting to note that the top speed of a car based on gearing is one thing, but the actual top speed will be slightly higher, as you've got more power (if you've got that really powerful skyline)

keep in mind that you may not be able to redline 5-6th gear b/c of aero, and not enough power to get past it... that comes into play...

it's not all gearing and power, you've got to have the power to overcome the aero.

OK, good point.

I guess I would say I was a speed freak growing up… I've 170mph or so plenty of times and 195mph once. I grew up racing my moms Audi turbo since I was 13. Ya I know I could have lost my license or should I say lost the ability to get a license till 18 driving at break-neck speeds so young. But I had fate on my side I believe. I would top out the Audi all the time at 165 or so. The reason I think it was accurate is one empty midnight road I came across a 3 series BMW to race. So we hit it pretty evenly until 155mph came around he began to slow up and I kept accelerating. So I assume the speedo is correct since we all know that all beemers have the 155mph limiter (with a few exceptions I'm sure).

Now saying that the GTR would be slower than a 5cyl turbo Audi is crazy. I've yet to test out my GTR to its limits past 150mph but I'm sure it would do 180+.

On another “my car can go this fast…” deal I drove my stock eclipse gsx to 170 with 3 people in the car to witness it. All it had was intake, lowering springs, and advan vs-5 wheels. Along with countless times of freeway racing to 150 or 160. Ya I was stupid and I haven’t done it since. But in all that time I never once got a ticket or accident. I swear it’s when your going slow that all the accidents happen. And my only tickets were a 5mph over and a 10mph over ticket. I also ran an eclipse club and the few gsx’s in the club all were able to attain the same top speed since there is no limiter on the awd model.

If your wondering the one time I did 195mph… 288 GTO twin turbo Ferrari. Look it up, it’s a badass car.

OK, good point.

just wanted to make sure we're on the same page, b/c we're saying the same thing, but differently... wanted to get my "mindset" or thought process out...
