I hit about 110 mph in 4th at 6000 rpm. Here is a sit that calculates how fast you should be going

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.

West TX RX-7

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?

West TX RX-7

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

He is talking about tire diameter, not width.

200km/h in 4th at redline. maybe a little over 7K rpm.

ORX705

tyre dia should be the same, no matter how big your rims are

West TX RX-7

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.

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.

ive seen 140 at about 6.5k and im running 18s....not sure how accurate the speedo was.

BoostedRotors

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!

christi

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)

RX7withNitrous

Faster than whoever im racing.

Bigretardhead

I went 120 at about 5500rpm in 5th

Crionics

Not necessarily. The way tire sizes work, you will not be able to get it exact. For instance, I went from the 14" phone-dials plus 4 to 18's. The tire size went from 186/70 to 215/40. If you look up some tires in those sizes, you will notice that the rolling diameter are not the same. I also suspect that if you look up 215/35's, the same will hold true.

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.

Amur_

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.)

88IntegraLS

I am a wimp. I have only had my S4 na up to 100ish. My acura struggles to get even that far.

Crionics

So that's about 130...is it stock?

sneakyasian

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?

BDoty311

I believe S4 N/A's top speed is 136 from the factory.

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!
