Yes, I can take a picture but I've got to warn you...they look silly!

The things we do for speed.

These were my trial run for a track setup, not to be used as a daily driver. I was testing two different theories. One that my calculations for rotating inertia were correct and two, that my gearing was correct. Before I spent big bucks on lighter/smaller/wider etc. tires and wheels and settled on a gearing I wanted to test. This only cost me some inexpensive Coopers. I've only got about 3" of clearance! I am happy to report that my math was right on. With my AWD gearing I wanted to hit 113 mph at the 1/4 mile and my Flashpaq speed was 110 mph with a shift off of 6,600 rpm a blink of an eye after! Based on that alone I think I was pretty close with the Flashpaq.

Speaking of tire size. That is another big variable. I have 255/45/20's, which makes my tuner times slower than it actually is. So I adjusted the speedo with flashpaq. But I wonder how accurate flashpaq's speedo correction is.

That is one of the great things about the Predator, you can enter your width/aspect ratio/wheel and it does the division and gives you a spot on size!

I also wonder if flashpaq and diablo secretly mess with the speedo to make our cars appear to be faster then they really are. But that is just me, the big skeptic.

Although it is easy to get jaded when hearing the crescendo of BS put out by the aftermarket I believe that both the Flashpaq and Predator do the math correctly.
* Edit * Joey, I decided that the tires/wheel combo was just too ugly to post. PM sent instead.
