i push my pedal as hard as i can every chance i get.... i iwll let you know how it works out in about 50,000 miles(I cant help it but maybe i will blow the engine before my warr. is up and i will get a new sr20!!!lol)
I dunno. I got behind my sentra, put it in neutral, and pushed all of my weight into it. No matter how hard I leaned, the car never really went that fast. Maybe 5 mph tops. I didn't see any sort of damage from this.
