Yes actually VERY bad idea. One of my buddies put his car in a ditch because he didnt have the car straightened out before he got on it. You better learn to control that foot before you build a bigger/more powerful engine. I'm not tryin to sound like a parent or anything because I hate when people do that.... but never floor it while turning, bad things happen. And you can ignore me and keep doing it, but one time its gunna bite ya right in the as*... and it only takes one time to ruin the car you put so much money and work into or worse, hurt yourself or somebody else.
