nickball75 Posted February 24, 2009 Share Posted February 24, 2009 Hey, My NA is still limited but is topping at about 120mph. I know it should be 112mph. So is my speedo out? If so is this something that can be easily sorted. Will be purchasing a thor unit soon to delimit but just curious as to why my speedo would be out. Could it be somthing to do with the larger wheels?

No speedo ever created is accurate at those speeds. 120 sounds about right for the limiter. Speedo's are designed to be accurate at 30, once you hit 100 they are usually around 10% out. Thought i better edit before the pedanticus-maximus come out. Speedo's on conventional cars are not made to be accurate, police cars etc are far more accurate.

lexsum Posted February 24, 2009 Share Posted February 24, 2009 speedos will always read over and should never read under as the VOSA chaps won't pass an import it if it is 1mph under at set levels. (eg doing 71mph reading 70mph) p.s. i assume that you found this out on a private road (or rolling road) ?! Quote Link to comment Share on other sites More sharing options...

Fearless Posted February 24, 2009 Share Posted February 24, 2009 Yes....rolling road:sly: lol I was going to suggest using a sat nav to get a true speed reading but that won't work on a rolling road. Quote Link to comment Share on other sites More sharing options...

It would have been in 3rd if you had your foot to floor, at about 112mph Quote Link to comment Share on other sites More sharing options...

MrRalphMan Posted February 24, 2009 Share Posted February 24, 2009 (edited) God thats funny.......... Sorry, must be the time of night.. There deffo should have been another gear in reserve. If you have your floor on the floor, it's going to be reluctant to change up. Edited February 24, 2009 by MrRalphMan I'm a pleb.

If so is this something that can be easily sorted. An N/A you say? 120mph? You'll probably find your car isn't limited and your speedo is perfectly accurate.

You'll probably find your car isn't limited and your speedo is perfectly accurate. looking through the forum, most members are saying it should do 140mph at least. Its definatley limited, you can hear it "flatline" at around 120 (on my speedo!) just before the KA over takes Quote Link to comment Share on other sites More sharing options...
