8th Day Creations has developed what may be the easiest to install, most cost efficient performance upgrade available anywhere.

Can't seem to find quality performance upgrades for your car? This is the answer. Each one of these adds an extra 10 horsepower TO THE REAR WHEELS! * That's right, the increases are measured at the wheels and cumulative.

Many of our test vehicles have also found a fuel efficiency increase proportionate to that of such world-renowned products as the Tornado, gas-pill additives, and many aftermarket cone filters! *

For years vinyl decals have been internet proven to provide incredible increases in RWHP. 8th Day Creations is the first to harness this physics-breaking technology and calibrate it into tire-shredding 10 rwhp increments.

Our 'Stage II' set includes 2 die-cut decals that may be installed to any location you see fit. Each decal measures 1.500"x5.000" and is cut from premium automotive grade vinyls. They come sandwiched between a waxpaper backing and transfer paper for ease of application.








*Performance increases recorded by 8th Day's own highly calibrated butt-dyno. Actual results may vary depending upon make, model, wind speed and direction, road grade, and astrological alignment.
