Yeah yeah, I know it's dangerous, but I just gotta know sometimes....
The temp was 15 degrees out and a few moths ago WITHOUT my OSCAI, I couldn't pass 128. After my install, I hit 133 and ran out of road...but I don't think it was going much more after that. Just thought I'd share...

oh yeah, does anybody have a top speed run comparison with a y-pipe and then without?

Thanks!

 

Plenty of people with Ypipes get up to 150 easy. But I dont know how much of it was because of the Ypipe or if it just got them there faster.

hmmm. btw, do you know the top speed of a stock max? 140?

 

A stock Max (4th Gen) will hit about 140. Most won't quite make it, but pretty close.

 

not enough speedo for this one.

 

Once, on a lone, long, abandoned hwy in the middle of nowhere*, our fearless SpeedRacer hit 144 mph (indicated) in his bone-stock Fed spec. 1995 Maxima SE, 5-speed. -He might have even made it one or two more clicks, but ran out of road.

Hey, like the others before me, I just had to know. May the Ralph Nader "protect me from myself" finger-wagging minions flame on!



*Only appropriate setting for an attempt like this.

he hit 140 in his stock maxima. i have passed 140 in my modded auto.

 

144, then an uphill, where I lost speed. Haven't tried again since.

 

I wouldn't say easy. The Max gets to 130 mph quite quickly, you almost don't think about it. But the 130-140 part takes some time, you've got to make sure there's plenty of road and free space.

Also, when I 1st got my Max, after doing a basic tune-up, I got it to 140 mph, stock with only a K&N panel filter.

funny how you are exact with your top speed

 

nice sig pic


My top speed was only around 100 or so. I ran out of room and didn't think it was safe going faster on crappy tires with hub caps.

 

I hit 140 bone stock.. now i go 150 and beyond

 

Now if only your comment made sense... Doesn't take a genius to guesstimate if there are no numbers. 144 is just about 140. Any other wiseass comments?

 

how do you calculate it past 140?

 

With the tach.

 

 

138 in my 95 SE with intake/exhaust then i ran out of road, definitley could have gone more! and the mustang gt 10 car lengths behind me topped out at 130.

 

what about the guys with 18 inch rims......how high have u guys hit??

 

150 .. but size or rims doesn't matter at high speeds

 

140+

 

umm people... how come...my car only goes to 120?
yalll said stock it goes faster... i have intake... and exhaust
neither of them ment for my car... but... well.. it jus wont go faster
is it cause my car is gle or auto or 97 (new laws inforce better stricter governor) ...

i wrote this on PHAT2k1AE cause i dont wanna sign on mines righ tknow
cause he's alreayd on it....

 

Thanks, it was taken just after a high speed run up the canyon

 

i don't know if gle's have limiters... i have a se auto... take od off and run it. it will take some room. if it losses power at 120 mph.. feels car hits a wall yes limiter.. if not keep foot on pedal and hopefully you will go till about 130 then turn od on

 

i cant figure out why your car looks like an i30 but has maxima badges... what country are you from? can you fill me in on this info, thanks

 

My top speed before I had my y pipe was 116. I hit 140* still pulling the other day, which I must say is a bit hairy on stock wheels and raised up coilovers. I'd say that its good for 146-148 now. I'm not gonna try until spring though when I have some real tires and my car lowered again.

Motortrend got 142.1 out of a 4th gen in an all brands top speed test...

 

Geez...I wish I live near some of you guys where I can try an all out top speed test. Faster I have gone was 130mph, then I ran out of road. I know I could have gone faster because when I stop at 130mph, I was still pulling strongly.

 

Just wondering, what rims are those str8ridin?

I know what you mean when I topped out my 1996 at maybe 150-160 (yes downhill) the speedo was well beyond 140, but my 1996 SE didn't have any mods and a little extra weight from my two best friends, the one in the back said "theres a cavalier up...back there" I just started cracking up when he said that.

 

thats pretty cool... its crazy to think that people from all different countries can come to this site

 

 

Sure they do. In most cases, larger rims have a higher rotational mass, meaning it takes more energy to rotate than a smaller rim, thus yeilding a slower accleration time and a lower top speed. Also, Larger rims have a greater contact patch which adds greater rolling resistance, which decreses top speed...for ex. 215 width vs. a 235 width tire.

However, if the distribution of mass through the tire/wheel package is equal for both stock and a larger wheel, some interesting things happen. If the overal tire/wheel package's diameter is larger than stock, the car will have a higher top speed. And vice versa, if the overal diameter of the tire and wheel is smaller, your top speed will be lower.

well i was talking about people with the right tire size..

and it doesn't matter at high speeds the size of the wheel.. that rotational mass BS doesn't mean anything..

 

so, you're saying that a heavy rim won't affect top speed?

 

On the autobahn, I've got the Autobahn Max up to 142mph, verified by my handheld GPS. The speedometer seems to be off about 5mph at that speed, as most cars are at high speeds (especially ones with speedos that only go to 140mph).

 

Dude - your suspension is broke.

 

that is what i am saying..

 

140+ with HEAVY 18in OZ's

 

You, my man, need to re-read your physics book. Weight, friction, aerodynamic drag etc. all play a role in a cars performance.

And by saying that, according to YOUR laws of physics, wheel weight doesn’t affect acceleration either.

Well, you apparently skipped physics 101. Weight, friction, aerodynamic drag etc. all play a role in a cars performance. Ask Road & Track, ask any Formula One fan whith no knowledge of engineering, heck, ask your physics professor, the heavier the rim/tire, the slower you go.

If you were to jog from point A to point B, would you get there faster wearing 100lbs shoes or 2lb shoes. Or, does it not matter?

 

if your shoes were rolling in a circle it would not..

let me explain something to you my son.. 16 inch wheels with 215/55 - 16 tire.. if you are running 235/40 - 18 inch tires.. the circumfrence is still the same.. its the same size... thats why we buy tires that match the same as stock tire.. ok if you don't understand.. go play with this tool.. http://www.miata.net/garage/tirecalc.html

being that the circumference is not different.. the wheel is still using the same amount of intertia to turn.. so in other words.. it don't matter what size my friend.. its the same at high speeds..

if you want to get into the technicality of weight.. then we have a problem.. because 18 inch Volk TE-37's are 20lbs lighter than 15 inch GXE Steel Rims.. and at that point.. you are still losing the argument..

anything further?

 

Further? Keep digging that hole if you please. I am well a aware of the overall wheel/tire combo diameter issue. Point in case, my two previous posts. I explained, excluding the weight factor, how if the overall rim/tire diameter is larger that stock, you will get a higher top speed. If it is smaller, it will yield a lower top speed. But as you stated the obvious, with 235/40 - 18 tire, it retains the same overall diameter as the stock with 215/55 – 16, which means little if no deviance from stock top speed.

But where you dig yourself deeper in that hole is when you say rim weight plays no factor in top speed. To use your word inertia, let’s use the example of ferris wheels, both the same size. One is loaded with fat passengers and the other is not loaded with ANY passengers. Further more, the loaded ferris wheel’s weight is distributed on the outside of the rim (more advanced Physics) . Which takes more energy to rotate? Ask anyone who is somewhat mathematically inclined and they will tell you the one with loaded passengers.

Same with a rim.
