nah, I just hook up an antannae to my laptop.

 

i've buried my 89 at 145 no problem thanks to shawns 145mph gauge

still had some 900 rpms to go too!

 

I no good at math, but you can use formulas to calculate top speed. GXE owners can also calculate their top speed based on the RPMs they are turning after they are no longer accelerating. You could make an equation from two known speeds and corresponding RPM in top gear (be sure your TC is locked), then the common value is your MPH per RPM. If your not blazed, as I am you can calculate how fast you are going.

My GXE with 230k will still do what I think to be 140. It has a Ypipe and I improved the intake.

 

H.. i've gone H in my car. sorry i mean approx 145. i have a 90 se w/ a 93 vg motor. i happen to have the speedo that runs up to 125 and i typically will hit the "h" in MPH before i stop pushing the car. it has more but whatever, already spent $$$ for one engine, might as well keep this one for a while

 

Good Deduction

 

smart move no blowin any motors like I did with nitrous

 

smart move u dont want to blow a motor like i did. blown 2 with nitrous

 

What did you do when you got the nitrous. Did you do the regular spark plug upgrades, used better fuel 91+, with some nitrous fans get a better piston rate, or get a better flywheel? I was seriously thinking about getting nitrous too. Ohh well my motor might be on it's last rev any day now so I might be looking for a new one in the near future.

 

calling BS right now. your needle did not hit the "H" in MPH, its not possible unless your guage is f*cked up and sits at about 40mph when you're not moving.

also, all you people are saying this and that about my speedo read so and so, well the speedo is NOT accurate above 115mph. do the math, put the car in 5th, sit at 120mph, look at the speedo and tach then figure out the speed using the final drive/5th gear ratio and RPM, that'll tell you how far off the speedo is..i only trust it to tell me when i'm going the speed limit in front of a cop.

now for my top speed? 149mph, speedo wasnt reading at all (dry solder joint somewhere) so i had to go home and figure it out from the tach reading.
stock tires, 5900rpm in 5th gear=146mph.
this was of course before new motor and alot of other mods...i could've gone faster but i saw a corner and freaked out and matted the brakes..sadly i could've taken the corner and went again but it was pretty scary..next time it'll be different, alot more suspension upgrades, better tires, alot more power.

 

I reached 142mph in my 1993 Auto SE VE when it was new 10 years ago.

 

I have done the same thing in my 92 SE and it was the most stable car I have ever been in doing that speed, or over 100 for that matter. props to the 92 SE's pushin 145 plus!

 

I hope you are joking.....

 

Of course weight affects how fast you reach top speed, but once there it makes no difference whether your car weighs 2000 or 10,000 lbs. It's called inertia. Wind resistance and rolling resistance are the only things you are fighting at top speed. Would you care to explain how I'm wrong?

 

Rolling resistance is directly related to weight....

 

my 88 celica topped out at 120 and then it completely cut power, the car almost felt as though it had died. when i pulled over the car was running fine and i was able to get back up to 110. that almost made me poop my pants coz i thought it was the end


i actually managed to get my car up to about 131 today, my buddy kept up with me in his lancer

 

Yes, but weight in and of its self doesn't affect top speed. It is a factor in rolling resistance, but there are many other factors that you didn't mention, like tire size, tread design, etc, etc,etc. Since you didn't mention any of the others or make the connection between the two, or even mention rolling resistance at all, I assumed that you thought wieght affected top speed like it affects acceleration; that power was required to keep the mass at speed. My mistake.

 

[QUOTE=MaDMaX024]calling BS right now. your needle did not hit the "H" in MPH, its not possible unless your guage is f*cked up and sits at about 40mph when you're not moving.

be quiet and stop thinking before you hurt yourself. it may be impossible to hit the H in MPH on your speedo since you most likely have the 145MPH speedo. i actually saw the needle hit the "H". when im on the highway and racing or whatever, i will typically run it about a 1/4 inch from the "H" which is more than half way from where 125 ends and h begins. oh yea.... my buddie with his supra actually gauged 145 and my needle does a really good job of sitting on top of the "H". so think again before you try to flame me by calling me BS... so STFU plz

 

YES I am saying weight effects top speed. Aside from wind resistance and power, mass is the largest factor in top speed. Power IS required to keep mass as speed. If you think weight doesnt effect top speed, see how fast you can run while carrying one of your friends.

 

if i'm not mistaken, i'd have to agree with MadMax. if i remember correctly the motor stops way before the "H" and not too far past 125 mph. i'll have to pull out my spare guage cluster to check though but i'm almost positive the motor is actually limited to just a tad over 125.

not trying to flame you or anything, i'm just basing this according to working on the gauges in the past. i'll check that cluster to be positive though before i say you are 100% wrong.

 

you're serious, aren't you? HAHAHA, OK, Physics lesson:

Newton's First Law: Inertia. If you have an object in motion (a car, for example, moving at 145 MPH), a force must be applied to it to change its direction or speed. Unless you have some external force (like wind resistance or rolling resistance), speed and direction will not change.


Newton's Second Law: F=ma. Multiplying the mass of an object by its rate of acceleration yields the force needed to cause that acceleration. This is an extension of Newton's first law of motion.

OK, at top speed, acceleration is zero, so the sum of the external forces is zero. The force exterted by the engine through the drivetrain to the road is exactly equal in magnitude and opposite in direction to the forces exerted by wind resistance and rolling resistance (really just friction). Mass could be next to nothing or it could be 25,000 lb. Either way, it doesn't affect the equation at all.

In a simpler example, how much does a bowling ball slow down as it rolls down the lane, where the rolling resistance is very low and the wind resistance is not very great? Why does a freight train need miles and miles to stop?

Apparently you aren't an engineering or physics major. Care to argue it further?

 

lemme school you:
i have a GXE speedo(or had one..it was from a parts car), which is how i know its impossible to hit the H.
maybe your speedo does do a good job, most do not. my friend's $40k audi read 148mph...thats strange, its ECU limited to 133, and it was still pulling so chances are that speedo is way off at high speeds.
i'm not saying you didnt hit 145, i'm saying your speedo didnt really come close enough to the "H" to be even remotely considered "on it", but i guess you're right, it does go halfway between 125 and the H. (silly we're more or less talking about a letter huh? )
i am however saying that your buddy's supra MAY NOT have any kind of accuracy above 115mph, just like every other car i've had experiance with.
like i said, look at the RPM, do the math (include non-stock tire size if need be) and it'll tell you how fast you're going. if you think that because its an almighty supra, its correct, you're wrong (shameless opinionated sh*t talk, supras < R33, R34 skyline/Z32, toyota < nissan).
dont post BS and i wont have to talk
also, if you have a personal problem with me, then you can IM me (PMs are too slow) and we'll figure it out there..enough p*ssing contests on this forum as it is (but i see it getting better).

 

i have CAI and hi-flow everything with fidanza. i've had my 5spd VG up past 125. it goes to 100 easily and without much effort. actually, too easily. once it is up to the 122-ish range, it becomes harder to gain additional speed so quickly (out of fear probably!), but it does happen. i'd like to take it to a closed track and really thrash it without fear. i can tell it can go faster. once i get the cattman headers on, i imagine the top-end will easily be 130-135.

it will blast an accord once i'm up in mid-range powerband, the later model ones, too(oops, did i say that? oh yes, it is driver skill over horsepower, like in D1)(hehe).

i'm more into torquey acceleration and "zippy" driving in and out of traffic than massive top-end. let's hope the headers don't kill that.

 

Top end wins races, low end makes it much easier to screw up your launch. I can barely chirp my tires off a hard launch. There aren't many FWD cars out there that can do mid 14s on street tires without having any traction problems. VE VLSD Autos OWNS ALL.

 

in a bone stock 93 se, i got above 145. I think i was going about 150 or so and still pulling.

 

i don't have any traction problems at all with mine and i even have the crappy vg tranny... <cough> i guess it could be the crappy oem clutch that barely wants to grip

 

I havent really tested TOP speed yet, due to my not so good rear tires. I was messing around one day last summer and hit 125 pretty quickly and when i let off the gas and hammered it again at that speed you could feel the jolt....so I'm guessing it had a nice amount left

 

I went 180mph on 215-45-15s

 

i tested the guage to see how far it would get to the "H" and it will indeed get about 1/4 inch away but there is no way for it to ever touch the "H" unless the needle isn't set up correctly which in that case you'd be reading faster than you were really going.

 

i went 755 mph on an overseas flight to japan two years ago. with tires retracted.

 

Army....Navy...Airforce...or travel?

 

on the way to the beach last year i maxed my 89 gxe, to 138mph and could have kept going with the digital dash it doesnt quit!!!!

 

turdlett, on korean airways to seoul, then to kansai. pleasure. saw lots of GTR's there.

maxine89, 138?! that is incredible. i'm too chicken **** to take my car up that fast on a highway even it can do it.

 

I had my 92 SE cruisin at about 100mph while it was hangin around 3000rpm. Im gonna try to max it out this weekend because I know a road by me where cops cant be. Ill let ya know

 

By all means be safe. Since you are on a VE and are going to top it out I want to be the first on a VG to top it out. That is after I get some better wheels and tires.

 

Korean Air? Dude...those planes are flying coffins. I lived in Japan (Fukuoka city) for three years and also visited Seoul many times as I have friends there. Even Koreans prefer JAL or ANY other airline over KoreanAir. Wonderful country....great people...but with one of the world's worst airlines no doubt!

 

I had mine up to 135 once and chickened out, but I was 16 and knew I had no business going that fast.

 

yea i also own a 2000 zx6r kawasaki nija so going fast is what i like to do... but yea guys deffinitly gotta be careful, when you get the butterflys in ur guts its time to slow down
