err.. normally I hear that mit engine is base on RPM to cut off.
I had been test on my car.. there is no speed cut after 180km/h
For example :
ur engine cut off is at 8000rpm.
existing gearbox can speed at 190km/h
change other gearbox with low final drive ratio : maybe u can get up to 235km/h
What is the purpose about the speed limit cut?? Till now i still don't really get it.. Can someone explain what it for? I had seen a meter also have this function, but i dun really understand what the SPEED LIMIT CUT for..
why is that so hard to believe?
I'm only making a guess here. Since all Gov speed limits around the world are way under 180kph (except the Autobahn), I think the speed limiter is a method for the car manufacturers to prevent damage to rotating parts like shafts and bearings and tyres. How many of us actually buy tyres that are safely rated for >180kph? It's a safety cutoff for people who like to drive fast but don't really take care of their cars.
Just my 2 cents.
Oh.. Mean if they wanna speed above 180km/h, they should put in speed limit remover? But i guess this is only for ECU car right? Carb engine car doesn't effect much right?speed cut = limit the car speed above 180km/h
if u wish to go further, u will need to unlock it. some can do it by flash ecu, or easier is to install RSM/speed meter....to unlock it.
the purpose is road safety....in japan, nmo matter wat car u drive. standard meter is 180km/h ,tat will be the max speed u can go in road.
if u wish to drive faster than tat, u gotta go to track. tat's all.
there is speed cut, rpm/rev cut, boost cut...etc
btw, not all car can reach 8000rpm, different story if u drive vtec or mivec which required to deliver power at high rpm.
standard car normaly wont hit 8000rpm for sure
my2cent n corect me if im wrong
