What is it?

Little story as to why I'd like to know.....

I was driving my daily driver (Infiniti J30 220hp V6 RWD) down the turnpike at about 70mph. I was in the center lane (hwy)and a 2nd gen was over in the left lane. His front bumper was side by side with my rear bumper. I notice the guy starts pulling up faster and faster, and then I floor it cuz I didn't want to get stuck behind a slow poke I was comming up against and then I go over to the right lane.

Funny thing I noticed was I was inching away from the 2nd gen! By the time I hit 115mph, he was almost 1 car behind me then I let off. I went back down to 80mph and he stayed right behind me. My governor (damn ecu) is at 117mph and I was wondering if I kept going, how far along he would have gotten.

my freind with a intake and a header back bonez exsaust....tops out at 140. thts on a dyno... he has done 130 though........

Ok, so I know he was just toyng around or he just didnt have the ballz to go any further

I was up to 130mph in mine one day i kicked it down and it seamed to have plenty more to go. Maby my gearing is different but at 130mph it was able to gain 5mph from kickdown in under 2 sec i stoped cause i didnt wana hit anyone incase ied hit a rock or somethin or a cop would see me, Am i blessed with an unusual rx7?

Mephis

and i frogot to say mines an automatic tranny, O YEA I FROGOT i have higher gearing (3.20 final drive) in mine so i must be special , wow i was stupied not to have though of my final drive b4 posting lol.

rotary>piston

my GTUs will max out it's narrow gearing all too quickly. at 120 the tach is at 6500 or so. I bet with my gearing I couldn't go much over 130.
I bet you could hit 160 down a hill

slow87turbo

well he might not have good mods.... or yes he was toying.....i dont know i am not him

My current top speed is 135. I hit that stock but it took me a while to get there. Now I can do 125 daily but anything after that gets hard. The road I did this on is not flat by any means so it is hard to make her go REALLY fast.

145 in mine.. i have a few mods... Yeah... the dude was either messing wth ya... or he was runnin with a puked motor!!!!

Brian of BNR Supercars fame hit 146 in a GXL a long time ago when he was racing an NSX. I think he said he shifted to fifth at like 8500 rpm.

my 87 gxl was redlined at 137 it was an auto. I could have pushed it farther but that damn buzzer is awful.

I used to have a crappy 86 n/a and I was doing about 140 on the highway before I got pulled over. Was pretty fun though

I've done 130 somthing on the interstate. course at the time my alignment was off so the vibration made my rearview mirror completely useless.

ive hit somewhere somewhere between 145-150 with my top down in my convertible. smooth as hell of a ride too, even at that speed. i travel between NJ and FL all the time and i have quite the numerous opportunities to do so.

wpgrexx

i don't know what it is in mph, but when i first got my ride, completely stock i buried the needle at 240kmh. that was almost 5 years ago

he didnt have the *****... youd be amazed how many people are scared to even go past 100...

I personally dont like going that fast either. **** can happen too fast, and then you're dead, or are in the hospital with a totaled car. Im not saying Ive never hit 130+ in my FC, but its been very few times (can count them on one hand) and I dont make a habbit of it. Its too risky..

Elrynino

I dont really like going that fast, its hard to explain to a cop why you where going 140 mph but thats just me

von

I did 145mph wich comes out to 140 if you take into account the tack being a few hundred rpms off.

Oh come on... you're speedo's off or you have got lotsof mods to be able to go faster than a TII.

Anyways, I've gone 210km stock, (about 130) and 215-220km (137m) or so after mods (still N/A) , That's on hilly terrain... don't know what total top end is- not much more though.

BTW- stock speedos are next to useless at that speed. They could be off by 20+ km's.
Use GPS to be sure!
I know that my speedo reads 60km when I'm doing 55km. (Radar gun tested)

Horse Power really doesn't have any effect on top speed, it only matters on how fast you get to your top speed. Also top speed on NA is higher than TII. Top speed is determined by rpm,transmission gear ratio, final gear ratio, and tire diameter.Formual: top speed=[rpm*tire diameter(inches)*pi(3.14...)]/(transmission gear ratio*final gear ratio), notice that this formula will give you the speed as inches per minute( so you need this conversion 1056 ipm=1mph).

Fifth Gear ratio for(86-88) NA is .697, for TII it's .762 their final gear ratio is 4.100. Stock Tire diameter for NA is about 25 inches and for TII it's about 25.5 inches. Redline for NA and TII is both 7,000.

NA top speed (at 7000 RPM).
[(7000 RPM)(25 inches)(3.14...)]/[(4.100)(.697)]=192385.03 inches per minute which is 182 MPH

TII top speed (at 7000 RPM)
[(7000 RPM)(25.5 inches)(3.14...)]/[(4.100)(.762)]=179493.7 inches per minute which is 169 MPH

It's true top speed of TII is lower than top speed of NA. But since TII reaches it's top speed much faster than NA so it faster in that sence but when you look at top speed NA is faster.

135 in my old GTU.... it wasn't very happy and took a while lol
