Default How fast have you gone?

Im really curious about what the top speed you guys have gone in your miata.
I also would like to know the top speed on the stock miata NA 1.8l and the 99-00 NB models as well. And of course turbo'd and just upgraded cars in general.

thanks

I wasn't aware that the Miata had an ecu top speed cutoff. I always thought stock miatas were just too underpowered to reach the top of 5th/6th.

Approx 110mph before the limiter cut in.
Car is a Jap import & limited to 180kph (easy to fix that, just can't be bothered tbh)
I read a similar thread recently & with the gearing we have 120-130mph is about the limit. generally.

There was never a limit put on anymiata speedo ever that i have ever known off most 1.6's and 1.8's top out in the 110-123 mph range lightly modified or unmodded. Turboed i can snap on 140 or so pretty easy when i have high boost going. But i don't have roads to handle that kinda speed here so i generally stay aroun 120 or so if i wanna wind it out.

i just did 120 in 4th on the dyno.

on the road i've had the car up to 140ish

if you wanna know what models will do what max speed in each gear use this page http://www.fatboyraceworks.com/gears/

you have to full in tire size, gearings, and your diff ratio(final drive)

you can get gearing info at http://members.aol.com/solomiata/Drivetrain.html

final drive ratios:
90-93 - 4.30
94-97 - 4.10
99+ 5 speed - 4.30
99+ 6 speed - 3.90
MSM - 3.90

(i think)

before you wanna question my 120mph in 4th on the dyno:
5 speed with 3.90, 215/45/15.
