Is it limited by a governor or cut-off? Ran mine the fastest ever today going to work ~ 95 MPH which was 4k RPM's. Hopefully it can take this for extended periods Just curios where it would stop though since the speedo says 140 MPH.

if you had searched, you would've already found your answer.

we are limited by drag.

Ive done 125mph in my 2003 Civic SI ( Canadian EX ). It equals out to about 202 km/h. I havent gone beyond that because quite frankly, its stupid and i'm too scared...lol

i did 118 and most of the cars are electronically limited i know i hit the limiter when i hit the 118mph

There are tons of threads about this, but it all depends on your car. Like with my 215-35zr18 i hit 135 and with my stockies i hit 125ish. I highly recommend not doing that unless you want your car to look like mine did after having a bad dayClick Here What you can't see is that my wheels were turned in the complete different ways. Trust me it's not fun i have so many problems with clicking sounds and the steering isin't right anymore and they fact that i indangered the 3 kids and 1 adult in the car i hit on the highway. Be smart not a dumb ***, and the highway was empty just took one person to cut in front of me and 135mph.
