I get what you're saying.
I'd be willing to bet just about every well maintained stock CSVT that rolls out the door will top out at over 140mph
Your 6 - 10hp mods and auto transaxle on a tired 130hp Zetec needs to put its trust in an inaccurate speedometer then present it as some sort of fact.
And your "know what speed feels like" isn't any better proof than an inaccurate speedometer.
One moment you say your speedometer is inaccurate, then you say that it's darn close, more accurate with your 17s, but you're basing all of this on your 14" tire run?
Ever been clocked at going 130mph or ever did any dyno runs to backup your HP claims, since you're kind of hinting that the factory might have severely underestimated your car?
Like the guy said, I'd guess that you're closer to 120mph
