i was trying to do a top speed run today, and the speedometer didnt seem to want to go past 120. i shifted to 5th gear and at that speed it didnt seem like the car wanted to move any faster, like it was giving up. is there something i can remove to stop this? or is my car just stuck with it and never going to go any faster.

 

probably maxed out power wise. I hear the N/As don't really accell in 5th.

 

Congrats, you've just found your top speed. Until you get more power, that's all she's got.

 

120? man that ain't much...sorry. My car pulls to probably 150mph, takin er to...115, then the tires started to fall apart...hahaha

 

You have an NA right? You're not getting near 150mph without another 100-110hp. Don't make silly claims you can't back up.

 

Roll up the windows +3MPH
Close the sunroof +1MPH
Headlights & antenna down +1MPH
All accessories off +.5MPH
My best ~126-7

 

The RX is my toy/hobby, if I need to go fast, I borrow my wife's northstar (~142)

 

Of course if you must go faster - go downhill & downwind. Or tailgate a 150MPH Semi.

 

yeah i've only gotten my '87 se up to about 125 with a K&N intake and no pre-cats.

 

i did a test run on my FC and got it to 140 well i got bad injectors and also my computer was cutting off my fuel at 8.5 of boost well some like it ,danm ineed to get a fuel cut defencer

 

90 gtu bonestock (at the time) 135-140 racing a svt contour on rt 18 in nj...

 

A stock Series 5 Turbo tops out at 135mph. Time to get your speedo recalibrated...

 

Oops, man a friend of mine, totally stock car. same as mine, sport edition, went 238 clicks! what the hell.

 

Well I have gotten 145 plus on a series 4 turbo so ha ha . but my current mods will put me way past than number. Oh 2nd gen don't worry I will only do 125 mph so not to dust you too bad.

 

okay, what the ****! I can go up hills there is a hill, with about an 11 degree gradient up by our local macks, and i was driving behind this guy doing 100 miles an hour....Up a hill! wtf!

 

actually it was @ 135 with a lil downgrade on the hill...

 

i hate that damn 120mph stopping point, mine stops around 122 or so, BUT if you find a nice long downhill on the freeway, oh man...my highest is 140mph, thanks to a downhill, it wold have kept going but when i looked down, and almost shitted myself, i thought it wise to back off. you know, this sucks consiering that i was in my friends 93 prelude when it was bone stock and it grinded out to top gear redline at 140mph, and it kept going past redline, waah, i want more power, but at least my friends GST is governed and he cant pass me on the free way, that makes me feel a little bit better.

 

Actually if you are above the 4k mark NAs do accell in 5th. I had my old '87 base model up to 137mph before. Currently I've had my '87 sport to 130mph. NAs aren't as slow as some claim they are.

So you either had 200hp, an inaccurate speedo or you were running downhill.

Guys, it's very easy to accurately calculate top speed from power and vice versa if you know the top speed and power of the stock car. So if you're gonna claim top speeds, back it up with some facts...

 

Maybe we should post pictures of our speeding tickets. (Hey officer, could you write that up at 150??)

 

Actually I was on a completely flat freeway. My car only had a RP 50mm cat back at the time. I can't explain it either, but I do know that it happened. It's very possible that my car's speedo was out of wack, but I doubt that my new RX-7 has the exact same problem. Unless it is a common problem among second gens. By the way, who would lie about a top speed? I know my car is slow and I don't have a problem admitting it.

listed car top speed runs are recorded in a one or 2 mile strech. given an long empty road. I'm sure all cars can beat there listed top speed.

 

ive hit 125 and still pulling in arizona where the altitude is fairly high also my speedo is off a lil', it says 77 when im actually going 80 so i duno what that means when im going 125+

 

i've taken my n/a fc to 127 on just a k&n air filter

 

I've hit 120MPH fairly easily, and it was still pulling (not alot, but pulling) Im sure I couldve hit around 140 given another 15 seconds or so. Of course that is what the speedo said, so I assume I was actually going 5-15mph slower than that. (All speedometers are off at high speeds)
