i was sitting here about to ---- myself watching how fast this thing is then i realized its in kph and not mph but still sick nasty none the less

Re: Whats this noise????
 

Thanks for clearing that up. Saw it go from 100 to 130 in what seemed about half of a second...

ssqv. sounds just like mine.
my brother has a greddy type-s on his stealth and it sounds nothing like that.

That's MPH. Most 'busas came factory with a 220 mph speedo, but maxed out in the 180's. If that was KPH, he would only be doing about 120mph @ an indicated 200kph.
