Boost makes torque baby! But is that the only way to make torque in a smaller engine like a 4.8 LS? In this video from Richard Holdener, he’s going to put a 4.8L through its paces to see if he can make big engine torque with the smallest of LS Engines. The good news is that he’ll be making notes and sharing all the results with you so that you too can make this kind of power with your own 4.8.
