After 46,000 miles and hundreds of runs over the past 4 years, she finally let go... But not without a fair share 10 second 135+ mph 1/4 mile runs. This was the original 4g63 motor from the factory, right off the lot. Our goal was to see what this motor was capable of... and to date, no one has pushed a stock Evo VIII motor harder than STM. This is/was the fastest stock-block Evo VIII on the planet.
It was caused by a miss-shift. The motor had more in it.
