top speed

[theboz]

I got a 4.4 R32 VLSD diff in my 90 coupe and swapped out the manual trans ecu for and auto ecu. This eliminates the speed limiter because of something to do with the transmission shift point for the auto transmission. I read that on a post in here and got an auto ecu for free and swapped it. I have had my coupe up to 120 before I got off the gas. I wouldnt expect too much more than that though as I was at about 6250 rpm's.

i know, my buddy was looking at a Volkswagon something or other, adn the sales woman said

"look at the speedometer, it goes to 160, that should tell you what a performance machine this is"

we left

wow jaja performance machine uh?i love it when my friends ask me about the speedo after 5 minutes of thingking about it, of couse they only see the numbers

[zippitta]

I am sorry but I am going to have to throw the BS flag on the Jetta doing 160. There has only been a few street vehicles that I have ridden in past 140... and one was my bike...RIP... it was a zx-6R and put down about 120 hp to the ground. (close to what a stock 240 has) That thing would stop pulling at 160...you want to tell me that a stock 240 with more than twice the drag is going to make it to 160....HE!! no. The other vehicles were highly moddified cars 500hp+.

The drag force of the wind is becomes too much for the stock 240 at around 130-135. And dont think an extra 50-100hp is going to do it either. Force increases exponentially. I would not be suprised if it took 350+ whp to push a 240 to 160.

Top speed is between 134-138. Maybe on the salt flats you can acheive more.I woukldn't say over 145mph because of wind resistance. Gearing is only to 155-160. I have gone 134-138mph but was clsoe to a 2mile run maybe a little more.

You can doubt it all you want... but its true. I have done a couple of pulls with him from about 90, and that thing hauls ***. I have seen him hit 140, and it was no problem.

The aerodynamics of bikes are HORRIFICALLY bad compared to cars produced past like 1965. For example, a bike with a REALLY good Cd (A hayabusa) has a .561Cd, whereas a stock 240 has like a .32 or something.

[zippitta]

I didnt feel like looking up your numbers, but I will go on ahead and take them at your word. The Cd/Area might be higher on the bike, but the force applied on a bike by wind is a lot less than a car.

But I am going to have to say that A sport bikeis a lot more sliptreamed than a 240sx.

The top speed of the 2005 Jetta VR6 is 146mph. The 2000 Jetta VR6 has 174 HP, but does not list top speed. The 2005 has 200 HP. Like I said, I doubt the 2000 VR6 goes to 160 without heavy mods.

[naed240sx]

Where did that stat come from, and is it a drag limited, computer limited or gear limited top speed? The 05 is a POS anyways that weighs a ton. That is only 14 mph away. Going slightly downhill could have helped as well.

[Florida240sx]

Pardon the dirty dash.

[Fenvy]

Pardon the dirty dash.

i get that all the time but I am pretty sure our gauge cluster is far from perfect.

Which is one of the reason why I;m caling some of you people running over 140mph BS.

It does not list gear or governed limit; which, tells me that it is drag limited. And when it comes to top speed, weight isnt really a factor, horsepower and aerodynamics is what it is all about.

Haha nice. I hope you were not the one taking that picture. that is what my speedo looks like when I top my car out. It read high before, and now it reads even higher because of the 4.4 diff.

[cyrus240sx]

you know if you look around on the internet theres a video of a guy in his 600whp s13 240sx that goes 170+ mph... he figured it out by math since he pegged his 120 mph speedo in 4th gear at around 5k rpms, then he went all through 5th gear up to 8750 rpm. figured it out by the gearing of his 5th gear in his transmission, his rpm, his final drive, and his overall wheel size.... the video is called "fast cars" done by a company called rhombus tuning

[cyrus240sx]

And btw, top speed is pointless anyway, if it wasnt, why would all german cars be electronically limited to 155 even if they can go alot faster?( like the new m5, with the limiter gone it can go 200 mph). And especially doing it in a basically stock 240sx, because any decent car will be able to get to their top speed alot faster than you can... dont get me wrong... i love my car, but without an engine swap or a turbo, 240sx's are SLOW!

[Charlie240sxt]

dont know how fast i was going but maybe one of the smart guys that read this can work it out for me

s14 5th 3.91 rear gears 255/50/16 tires in back 5600 rpms

They run mid-high 15's stock if you can drive. That's faster than 90% of the cars on the road, really. You have a skewed perception of what slow is. Go drive a metro and you will understand the true meaning of slow.

[0wn3r]

it'd probably just be easier to go buy a radar gun and call it a day....

[Tulsa_S-13]

Charlie240sxt, my Ti-89 says you were going 135.13 mph, you than have to factor in air resistance, etc.

Check out this thread if you want to know how I found your mph zerothread?id=133075

[Charlie240sxt]

i think it was faster then that cuz i was being tailed by a car with 135 on the speedo and he told me his was toped out

no its not that i have a skewed perception, its just that what a 240sx is, which i consider is a sports car, it is damn slow, considering pretty much every other sports car will beat it hands down...

all of my friends are car people, so they all have nice cars, and im my group of friends i have the slowest one! do you know how much that sucks! thats why i consider 240sx's slow, its a completely different story if you have a turbo or swap, but since i live in cali and want to stay legal, thats why i have a 1972 240z that im fixing up... no smog, so i can do whatever i want

[blackS13]

does cutting the yellow and green wire on the DOCH just disable the the speed limiter or does it kill the spedo also?

[kansas240]

just need proper motor-vationhttp://www.scta-bni.org/Bonnev...s.htmdone with a flathead fordwithout a timeslip, you're full of ****

[91RMKS13]

I have done the math 7 grand in 4th brings you to 125, 7 grand in 5th takes you to 170. with gears from an infiniti j30 i think it brings those speeds up about 7(dont remeber exactly it has been awhile since i did the math) mph faster in each gear. Also I have snipped the govenor on my car and 125 VERY easy to reach and pass. for any of you speed demons that are wondering what your speedo would read if were not limited at 115 should look at http://www.lsauto.com/products.asp . But sadly in the end you top speed is limited by your cars POWER which I think was already stated. Oh yea i forgot i have also seen the video talked about earlier but the car only had 500hp and it did do 170 in 4th and with the speed at which it was accelerating i know the limit was still far away with the revs it was capable of i think the top speed is over 200. I heard that after the video the car was sold for 16 grand then with 669hp.

[Fenvy]

most of this pages' post seems to forget about 1) air resistance 2) tach isn't accurate, it's only to be used as a reference and is usually faster than what you're doing

[kansas240]

if a naturally aspirated flathead can push 150 almost, surely a ka-t can do it with a little aero work. If you can put on a turbo kit, you can dodge a ball.

150mph? any accurate record of this? is it stock motor with stock gear ratio?

theory is one thing, reality testing is another

Try this pic on for size....

The only mod this VW R32 has is a chip that removed the rpm limiter. This was on a flat stretch of highway, corrected it is about 176 mph. My 1.8t jetta with a chip that ups the boost and removes the speed governer will only get up to right about 155mph gear limited, bouncing off the rev limiter. It does get there fairly quick for a car with about 230hp, full trim and with 3 people in it. The 240 will not do more then 140 period..... I drove my 93' hb only with a 3inch catback along side my friend with the R32 and after for-freaking-ever on the highway the highest he read on his speedo next to me was about 139-140.... it just will not go faster, now a Ka-T, that's another story of course .

[dal2kvvisp]

i was riding in an SS camaro beside a friends 92 base model hatch, 70 k orig miles, hotshot header, aem intake, kyb shocks and eibach springs, and a 180sx vlsd, we hit 160 in the camaro right next to the 240 ( govorner's removed, gear and top speed) at which point the camaro driver's gf started hitting him from the back seat telling him to slow down....

sounds skeptical i know... i thought the same, but after seeing that, im a believer, i need to test my 240 now...

i hit 138 at a slight downhill in my dad's stock 93 auto coupe with the digital speedo, its an automatic... and apparently auto's dont have a govorner

[kansas240]

how many times do people have to say speedometer error before you listen? gps or a timeslip. thats proof.

tires grow at speed. the increase in diameter changes the final drive ratio. speedometers are not accurate even at 100. sportbikes are affected as well. it doesn't matter what kind of car your friend has. TIMESLIPS!
