I have been readin the forum off and on all day..(snow and rain here)..I've seen a couple postings of speed in an N/A..roughly 145-150 mph. I can see the n/a doin 120 (easy)..so ..gentlemen(and ladies,sorry)..start your engines..how fast have you got your car to do..N/A..(hell TII also..I like to read!)..and type!!!

 

About two miles an hour... rolling down the hill off the tow dolly

Hopefully it'll get a little faster in the next few days

 

N/A Top speed acording to Mazda and other tests (stock) 130 mph.
My old FC I think was around 130 ish when I let off. The speedo's are notoriously inacurate around 100 and above. They seem to have the tendancy to read optimisticly.

 

Well, I've gotten the speedo to over 145 before. Since its about 5 fast at 60, I would assume its about 10 fast at 130, so that would put it about 135 or so. The previous owner actually clocked it at 131 with a radar gun on the race track, though. And that was with nothing but exhaust, intake, and a 200k engine.

 

I wouldn't trust a non-timed, GPS'd, or radar'd speed on a NA.

I believe 8k RPM in 4th gear with normal tires gives you 135mph or so, and you slow down in 5th because the engine doesn't have the power to go any faster - that's why a TII is faster, it can wind out 5th.

I've been "officially" clocked at 106 (by a cop... that wasn't fun), but I've wound the speedo up past 125 or so. There was still some left, but it was when my aux ports weren't working, and due to that minor speeding ticket I haven't pushed it even into triple digits in the past year.

i think ive got you beat!

Gotten my first 90 vert up to 125mph in 4th gear.

I've gotten a clocked speed of 117. Good 'ol sheriff was kind enough to help me with that. (not really)

 

ive gotten my na up to 135 in 4th before,i have a full exhaust, car dynoed at 133HP to the ground, with alot of miles on it,

calculating with my tire size and rpm, 8000 in 4th is like 139.5 mph or something like that, i was very close to 8000,

 

137 at around 7500, maybe more, RPM in my S4. STOCK.

With a tailwind, going slightly down hill. It also took me a VERY long time to do it.

This was with the stock tach and speedo, on stock 17x7 205/45/zr17 tires.

NA by the way, during Fall...probably like 45 degrees outside. Probably around 10 mph off.

 

fastest i went was 122mph. could've went faster but at that speed it wants to fishtail. i gotta make my ride lower and get low-profile tires. tokico blues with stock phone dials, 195-70r-14 tires. it' just too high

 

We've covered this many, many many times and usually it just turns into a pissing match. So I'm going to close this topic. If you search for "top speed", "maximum speed", "speed limiter" and variations on that you should find all the info you need.
