How fast are you going...
when you top out 4th and 5th gear???
|
I hit about 110 mph in 4th at 6000 rpm. Here is a sit that calculates how fast you should be going
www.sgmotorsports.com\mph.htm |
I've hit 138 in 4th at about 7K
I think the car would have done 140 in 5th...that was when the car was still NA...I'm shooting for 160 now. |
Depends on how accurate my speedo is. It's accurate at 70mph I know but on up there I dunno. I've read 155-160 on it though several times. West TX, long flat straight roads with no traffic. That was in 5th gear at about 7200 rpm if I remember correctly.
|
hmm I was at about 130 at 7~8K RPMs.
Do S4 have a higher gear ratio? :confused: |
tire size makes a diff also.
|
i have an auto with 9'' tires and all well i made it up to 130+mph then i let off the gas and let it idel and i was able to maintain it at 4k rpm, i win ;)

200km/h in 4th at redline. maybe a little over 7K rpm.
|
tire size makes a diff also. |
diameter can be diff on same sized rims ie 245/45/16 vs 245/60/16 or 245/35/16. 35 would be shorter than the 60.

ive seen 140 at about 6.5k and im running 18s....not sure how accurate the speedo was.
|
Mine has indicated 160, though I dont know how accurate it is. Now it indicates 0, even if it was running...my speedo cable came out!
|
in 5th gear, at 4k RPM I was going 100. Was on the interstate here inPcola, didn't want to go any faster, cause of the cops.... heh but I've been 115 @ 5k RPM.. in my car...

4th at about 7500= 147 mph (if those speed thingys they put beside the highway are accurate)
|
How fast are you going... |
I went 120 at about 5500rpm in 5th:)

Originally posted by ORX705 yep, what i'm trying to say is if you get new wheels the tyre specialist will sze the tyre so the overall dia stays the same. And, btw, Anyone here got an S4 NA? I am kinda agitated b/c b4 my engine was replaced, I got the car up to 120 in 4th ~ 7k, but any shift up to 5th, and I start to lose speed. After my Mazda Reman. engine was installed, I topped out at about 118 in 4th. Granted most of these cars getting 130 140 150 etc, are Tii's and S5's, but I am curious to see if this is typical of S4 NA's. These speeds are all with my 14's. Haven't bothered runnnig with my 18's. |
210km/h in 4th last October - don't remember the revs but it was above 7k.
Couldn't get her above 200km/h in 5th on the same day. And she's an s4 (non-turbo.) |
I am a wimp. I have only had my S4 na up to 100ish. My acura struggles to get even that far.
|
So that's about 130...is it stock?
|
I've driven my acura to 150 redlined in fifth. never been near that in my rx7 87 NA. the acura was a 95 vtec so there was no speed limiter. plus the wind was at my back. between ashland oregon and medford oregon on I-5. My fourth gear in the rx7 is about the same as the fifth in my integra. would a 91 lsd diff shorten that ratio?
|
I believe S4 N/A's top speed is 136 from the factory.

Now I've driven a 2001 Vette 6 speed and pulled 175 in 5th, then switch to 6th and loose 10 mph hehehe, Same thing with the Dodge Viper (Same buddy had the Vette that I drove,... rich prick) but the Viper would do 183ish in 5th then drop 10mph or so in 6th.
If I had a choice of a free car that I could not sell but had to drive, the Vette would win hands down. New Vette Mo Betta than any rex I've driven, there a dime a donzen though unlike an RX-7. I've seen maybe 6 different rex's on the streets in my area of 250k ppl or so. |
ya with 205/65/15 130 in 4th gear at 7k RPMs
|
Originally posted by cryptowave I do 100mph in 4th and come in just around 5k rpm. I rarely friggin use 5th gear cause the pull in 4th owns me! eek, I could be wrong. I don't know. I don't go that fast anymore since I have been pulled over - not for going that fast though, just for speeding.. lol. |
135mph in fourth @ around 6500rpms.
Not too sure b/c I was too scared to take my eyes off the road. 90 N/A ...oh yeah, three people were in the car...the other guys were sleeping, didn't even know what I was up to! |
Originally posted by Crionics So that's about 130...is it stock? Was this for me? No, she wasn't stock. Downpipe and hi-flo cat and K&N in the stock airbox. The airbox has since been dropped for a very nice DIY cold air box. She just needs headers and a cat-back and that'll be it for engine mods for me. :bigthumb: I haven't had a chance to see what she'll hit with the new box yet. Soon, I hope... :zip: |
My '89 convertible and my old '90 GTU both read 140 on the speedometer at about 8000 RPM's, maybe pushing a little into the redline. I doubt they're actually going that fast given speedo error... but that's what the speedo said.
The only time I ever see those speeds anymore is on my CBR. It's not exciting to do in a car, so I don't do it. |
Originally posted by christi well, when im on the interstate, i automatically redline 1-4 and then hit 5th gear. I know about 5500 in 4th gear is about 85-90, or so it was last time..... I did it.. lol eek, I could be wrong. I don't know. I don't go that fast anymore since I have been pulled over - not for going that fast though, just for speeding.. lol. Maybe i'll give 4th a redline test tomorrow... I'll bring a box of doughnuts just in case. |
I don't know how fast I was at in 4th but I have been at 155 in 5th before and it was at like 5500 rpm. I do believe it would of went 160.
|
I should get a picture of this...
I was going 85mph @ 0 rpm! My rpm gauge broke this morning! |
Well this sucks.. I topped out at 124 in 4th out here on I-71.. I was hitting redline too! But this was back in the day, last summer, when all I had was just dp/mp/cat back. Plus I'm pretty sure my turbo is caput. I shifted into 5th, and lost like 2 mph. ZERO pull what so ever in 5th gear. And whatever car it was I was racing, some big luxery sedan PULLED on me and left me. It was SAD!!! I remember doing over 120 in my '89 GXL one night and was pulling in 5th gear. Let off though. I was scared :). night time, country roads.. animals.... Wrecked that thing though.

Yes officer - it was 55 exactly. :angel:
|
Never taken it past 105. Too many cops around
|
ive hit around 125 without redlining 4th gear, but as soon as i shifted to 5th I started to lose power, the car didn't seem to want to accelerate much more.

143 at about 8100 rpm in a n/a t2 tranz and diff in 5th with buddy on a gixer 750 clockin side by side
scary body had 250,000 on stock rubber not a good feeling |
^ lol, you got some balls keeping it at redline for that long :) I've topped my car out at least 3 times. 7900 rpm at 135mph in 4th, 5th gear it starts decelerating.

142 in 5th down hill normaly 136ish

S4 Redline Speeds (@ 7000) Assuming non-86, NA tranny, 24.7" overall diameter, manual transmission, mph scale
1st: 36 2nd: 63 3rd: 92 4th: 125 5th: 179.89 (Yeah, not going to happen on a stock NA, or any NA for that matter with this tranny) S5 Redline Speeds (@ 8000) Assuming non-GTUs, NA tranny, 24.7" overall diameter, manual transmission, mph scale 1st: 41 2nd: 72 3rd: 105 4th: 143 (You'll have difficulty on a stock NA) 5th: 205.59 (Yeah, right) 86 and GTUs speeds are slightly different, 86's will have a slightly lower 5th gear max speed with better acceleration than its S4 bretheren due to a slightly taller 5th gear. The GTUs will have a lower top speed in every gear due to it's 4.3 Final Drive Gear as well as better acceleration and even lower top speed in 5th due to it's significantly taller 5th gear. (Think 10% taller, which equals 10% better acceleration in 5th gear based on 5th gear gearing alone) |

Granted, I've done a couple things to my motor so it isn't stock, but nothing as drastic as any kind of port job. 110 is a daily drive to work (and on occation while at work), so that probably accounts for the rear end problem I'm currently wrestling with. |
use this link.... thanks to Roen
http://www.kabamus.com/garage/gears.html You guys need to live in the boonies so you can mess around :) i usually only do 4th gear pulls but 3 times now we have done full 5th I dont have a speedo back in the car yet, but i had always thought around 180 but according to that site it was around 193........ Math never lies 275/45/17 DR's, 4.1 rear......... I had the rev limiter set at 7.5k and i know i got there each time because that is were i had the hard cut set at and it hit hard cut each time s5 TII tranny are a .752 right?? way waaaay back the na auto would take awhile but get to about 135 on the stock guage |
.719 actually
S4 TII is .762 S5 GTUs is .752 |
Whoa.... I guess the S5 TII has a .719 ratio not a .752 like i thought....
With that calculator that means 202mph at 7.5k with my tires and rear..... How the fuck could it be that fast???..... I always thought in my head about 180, def felt fast but i didnt think that fast, cuz it pulls too hard in 5th for me to think it got to those speeds as quickly as it does maybe no more of those for awhile :) edit... ha, roen i had just found on mazdatrix it is a .719 too |
This thread is 4 YEARS OLD!
|
blame the n00b, i just posted the end-all speed chart as defined by gear ratio. all questions should be directed to that post.
Good ol' Mazdatrix and their ratio page. |
let me see, following an audi on the freeway here in norcal at 135 mph in 5th at i think 6 or 7g, cant remember, all i know is i was flying.
peace |
