i have goten up to 145, could have gon faster but decided not to , but i did in down the 5 freeway in cali 3:00 am, so nobody was out and in the car alone 88 rx7 n/a turbo, how fast have you gotten...?

 

n/a turbo? do you mean either one or a conversion?

 

General consensus if I remember correctly is that the speedo is usually completely inaccurate at high speeds.

That said, I've had mine to 120 before - didn't have a long enough stretch of deserted highway to crank it open, and the road was getting a bit bumpy at 120. Right now it's top speed is however fast I can push it.

n/a a non turbo i only got an exhaust an air filter, rpm was only at 5k rpm in 5th (of course)

 

i was up to ~125 (reading on speedo, don't know actual speed) on my n/a. but for the past half year, it's been at a constant 0 mph. Still trying to work out some bugs on the vacuum hoses on my fresh rebuild

 

145? are you kidding?

 

umm... 4th gear is faster, i dunno about climbing to 145 in 5th unless you were already at 145 in 4th then shifted...

 

but ive hit 88 mph in my 91 NA then i went back in time...

 

no not kidding i was pretty amaized my self, hey it regesters at 150 i bet it will go faster than that but i wanted to see if it would do what it said, hell why not

 

 

to tell the truth its a big hill, but i still did it its the truth

 

i know sounds iffy but i DID

 

i've done 150 in a volvo

i guess another way to check your speed would be to check your engine RPM and do the math...

 

but the speedo was prolly off...
dont really matter neway, its very unsafe to drive at those speeds.
well i did 135 once...

 

the rpms dont lie 5th at 5k rpm, come on its at least up there aways

 

RPMs do lie. You can adjust the tacho in case you didn't know.

the RPM's might not lie, but i think you might

 

You must have the old flux capacitor. I got the newer one that you only have to go 35mph. Speedometers are pretty off usually by 5-10mph. According to my speedo I've gone as high as 137mph but I have a S5 auto with a 3.90 rear end which goes a little higher top end that the 4.10. Also the 5th gear on N/A trans is almost none existent.

 

yea i cant afford the new ones, or the old ones at that....
i had to make one

 

Did you get the idea when you fell while trying to hang a clock?

 

soo anyone wanna calculate how fast is 5k rpm in 5th gear?

 

nah smokin crack works better for me when trying to come up with ideas...

 

z4csI428 hey prove me wrong dont call any body a lier inless you got proof to back it up. ideas and i thinks dont cut in the real world, so unless u got actual proof i didnt hey a hill, rotary, open road, it could happen and it did so shut the f... up k

 

z4csI428 nothing u say makes sence any way

 

Chill out dude. Your speedo may have said 145mph but it takes quite a bit to get that high. I saw a S5 TII barely run 147mph at the salt flats with a few mods. Don't take it too seriously because there are a lot of tired 7's that barely do 120mph. I think the S4 TII topped out at 138mph so thats why it seems unbelievable.
(edit: He really does have a flux capacitor I ran into him earlier this century.)
