Something seems wierd. It's accelerating like crazy from 130-140, then stops close to 150, slows down, then takes off again, but it didn't sound like he lifted. They should have showed the road if it was real.


That's what i thought. You could put 4.10s in with a stock gear and maybe hit 120 and it would read about that high.
 
Yep, sounds like a 'calibration' issue as well...

The % increase in gear, makes the speed increase more and more the faster you go...

3.73's over those factory 3.27's is rougly a 14% increase. So at any given speed, your speedo will show 14% faster than he is going...

So the faster you are actually going, it shows even faster...:)

It isn't just a '10 mph' difference...

150 actually turns to 171 (speedo) and 50 mph actual is 57 (speedo).

He did lift at the 145mph mark or so...when it 'slowed down'...

I'm sure he shows all his high school buddies the video:rolleyes:

It's not a Saleen either...

no we have a vid of it, its legit, mind you he has like a 3.45 speedo gear so it is off a little but not that much, he has 3.73's and yes we were pulling from jon like he was tied to a stump. never underestimate the power of a ported pi swap 4.6, with lots of compression!!!
